I got my SGSII on Sunday and I am extremely pleased with it. Its like the phone of my dreams in almost every way. It's responsiveness, its camera, its form factor, its screen, everything about it was great. Until I noticed that the battery was being drained kinda fast. I rooted it within a day and tried every ROM available so far but none of them alleviated my battery issue. I've read and tried every solution on these forums but nothing works.
I lose approximately 10 percent of battery every 30 minutes and have gained a maximum battery battery life of 8 and a half hours. Ive Frozen most of sammy's bloatware and have optimized it as much as i can. i disabled fast dormancy everything.... I just dont know what to do.
Did you try restoring original Samsung firmware, factory reset with full wipe, and then doing initial setup prior to getting on wifi?
Try this, don't config any account besides google, don't install any software and certainly don't freeze any apps. Monitor phone for a few hours and then post screenshots of Battery Use app for us to see.
I get about 15+ hrs worth.of battery.
With heavy exchange (push) email and quite a few apps.
My problem is random reboots especially when playing music.

Wait for some days. Battery need to calibrate and take some charge to be fully operational.
See pic, I got better battery life than my x10....

Give it some time. Battery life improves quite a bit after some discharge cycles. Do a factory reset and reinstall as some have mentioned above.
And remember some apps can cause the OS to misbehave.
That's the reason I sold mine. Battery life was unacceptable. Other than that, perfect phone!!! Still looking at this forum hoping for solution to battery problem. Would definitely buy the device back then.

Thanks for the advice first thing in the morning ill flash KE7, which is what my phone came with, and report back with screenshots and after a few hours.
Any smartphone battery need at least a good month before reaching the maximum potential.
Just wait a couple of days and use custom kernel with SetCPU.
My ex-Arc did the same, first day battery droped 7% every hour on idle but after a week battery could last 3 days
if u continue in this topic its very better. 1 topic about battery is more better

For me, it's simply because i'm battering the phone with internet use, and generally playing around with it constantly all day while at work.
I get a full day, sometimes two now, depending on how I use it.
My old HTC Desire used to need charging twice a day, until I got my SGS 2, now the Desire needs a charge once every 3 or 4 days, due to the fact I am playing with my new toy! lol
I'd say battery life will improve as time goes on and usage of the phone goes from all day, to normal smart phone usage
In all seriousness, the SGS two outlasts my Desire easily, which is good enough for me. I struggle to kill the SGS 2 in a day.
If you are losing 10% per half hour, is that with the screen on? If so, that is fairly normal. I find that 5 hours of screen on time is the most you'd normally get. If its in standby mode (screen off) and you are losing that much per half hour then something is wrong.
Those you of who are getting amazing battery life, would love to see a screenshot with more than 5 hours screen on time - just to see if it is possible. 3 or 4 days means nothing if its in standby 99% of the time

Yep, how you use the phone is huge. Screen brightness and many other factors like installed apps and what they are doing can have a major impact on batt life. IMO battery life is almost impossible to compare except your own in static usage after making changes. Even idle batt life is effected by push email, weather, etc. In my own usage I was getting poor battery life to start with (multiple charges per day) or was I? There I was screwing around with the phone constantly. Loading this, uninstalling that, taking browsers for test drives, trying launchers, flashing roms, seeing how different games played, showing other people the phone, and so on. The excitement wore off and I got to normal usage (for me) which since I unplugged 17 hours ago is 18 texts, 7 calls all of which were short, and assorted stuff like doing a search, a little web browsing following the search and so on. I'm at 61% showing on batt and my largest user was screen with 59% and then OS with 11%. So this is pretty obvious, cant make it through the day hammering the phone but no problems with what I think most people would consider light usage. Where I'm going is that I think some people may not realize how much they are using their phones in their wahoo new phone frenzy.

Quoted for truth! With normal daily usage about 12-14 hours off the charger you'll see 5 hours of display at the most. GSMArena has done some tests and in airplane mode playing a video on loop on 50% brightness can last a bit over 8 hours. Once you add in having to maintain a cell signal, wifi, push email, idling for another couple hours, it reduces your possible screen time in favor for those other activities.
The best ways to conserve battery are to make sure you don't have rogue apps that are keeping your phone awake when it should be sleeping. Check your battery graph and actually CLICK on the graph to expand it to check if your "awake" bars line up with your "screen on" bars. If they don't, something is wrong and you have to find out what's causing it to stay awake. If you've been browsing (white) websites on wifi for 5 hours and complain when the phone says low battery... tough. You're using the display, wifi, maintaining a cell signal, as well as viewing sites that strain the SAMOLED display the most - white backgrounds.
Based on my experience, my battery life is actually quite good. After 4 hours of idling and only about 20m of display on (auto brightness) I'm still at 91%. After a day's use with about 1h of screen time and 14 hours off the charger (about my avg workday usage) I end up around 65-75% which I consider not too bad and can definitely go 2 days on my average usage. Basically minimizing the battery draw when the screen is off is key since when the screen is on, nothing can stop it from draining the battery.

Mine,
From 100% to Full drain (Switch Off). Total usage 1d 19h. At 20% Brightness. On XWKE8. More than 5 or 5½ hours is NOT possible, whatever you do. It's not that I am impressed with it, 5 hours isn't enough, 7-8 hours would be good though
Regards.
Well i left my phone idle for approx. 5hrs and im dwn to 63% but now im noticing a problem that i havent noticed before... my Android OS is now taking up 38% with which is more than Display which only took 21% and the phone was constantly waking up. I have no apps runnin in the background nothing else out of the ordinary.

You must have SOMETHING that is eating up the CPU. If you are out of guesses, do a factory reset with data wipe, restore original firmware (if you flashed a custom rom), do another factory reset, configure only gmail, and then monitor the battery usage. It would be losing at most 2% an hour in standby. For me it was 1% every 2 hours (with absolutely nothing running except google) when I tested. I the slowly added my apps making sure I do not install crap and do not configure osmething to always do some **** I do not want.
I don't understand these "battery life sucks" threads.
I have an Unlocked SG2 with stock ROM. It is not rooted, I have not frozen any apps. I have four exchange accounts syncing on push, social networks up and running and widgets on all of my screens. I text and check e-mail frequently throughout the day and I use the camera here and there.
I always get at least 15 hours out of my battery, if not more. For comparison, I was using an iPhone 4 under the same conditions (with the same accounts syncing) minus any widgets or automatic social updates and I was getting roughly the same battery life.
No, this phone won't last you a week with heavy use, but you should easily get a day out of it and I rarely find myself in a situation when I can't charge it overnight. This phone is on par with all of the best battery life smartphones out there, as far as I'm concerned. Those of you getting horrible battery life should probably look into an exchange or maybe an app you recently downloaded. The only time I got really bad battery life was when I ran a live wallpaper that was pegging my CPU.

If you are happy with 15 hours back up with the stuffs you mentioned you do then I've nothing to say. And AFAIK, iPhone 4 has much better battery back up than GS II, in fact it's the only phone, rather smartphonecool which has the best battery back up atm.

Before going to sleep do these things,
A- Check if 'Auto Sync' is running, Disable it if it was. Same goes for Background Data, Disable it.
B- Go to Task Manager and see if any Apps are running. Close it if some were.
C- In Task Manager, go to RAM tab, Press Clear Memory, it should close the hidden apps were running. ***DO NOT do this if you have some kind of Scheduler application running, it will NOT work then***
D- Download an app like Auto Task Killer.
E- If possible keep the 'Power Saving Feature' on with your desired settings.
Do these first, if not worked, do a Hard reset. For me, it decreases about 5-6% battery (max) in overnight period of 8-9 hours.
Regards.

I'm not sure what you mean by "battery backup". Are you referring to standby time? Yes, the iphone does better in that department, but that's not typical daily use. Phones are meant to be used, not sit around for days at a time. Iphone can do this because it doesn't truly multitask and no data is syncing. Either you have a faulty device, bad Rom, or your expectations are unrealistic .

sucks. I know there are threads about this but I just am sick of this. I had the Evo for a bit and I swear that battery life was better.
I don't know if its because of my crappy reception or what--but I can't even last a morning of light use with this phone. Super annoying... I had high expectations but when i'm getting low battery warnings before noon with barely using the phone at all, something has got to be wrong. I did a factory reset, did a full discharge/full charge. after it said fully charged i unplugged and plugged back in. i don't know what else to try. should i replace my phone? ask for a different battery? the date on the battery is 8/14.
Ok my rant is over...publicly that is.
edit: mods you can just delete this thread. i also hate clutter and hate that my rant has added to it. (hopefully we get some sort of update/custom rom soon that fixes battery!)

The battery life on my EVO is not better.
What do you do with the phone that drains it so much?
Open up your battery statistics. What is using it the most? How long is your display on for (select "display" from battery history and it will say long long it has been on for).
Have you charged it correctly for 1st time use? (charge to 100%, then drain to 0, then charge to 100% again)?
Seems like you are experiencing much faster battery drain than expected. My battery lasts all day long with light use (~22 hours). 10-12 hours under heavy use (3-4 hours of screen on time). I use juice defender as well, and I keep my screen brightness at 0% (still pretty bright) unless I go outside).

i've done everything you said. this isn't my first smart phone.. i've been around a long time. :-/. from what i have been reading some have been getting the ok battery life while others are in the sinking boat with me. just frustrating..i've been giving it more than one chance since i got it at 8am 1 week ago.
Bro turn off wat u don't need. Auto sync is adrain and having data connected is a drain as well. If ur not using the data then turn it off. U can still txt n get calls. N when u wanna check the net or watever then turn it bak on.

In Battery Usage / Cell standby, what is your time without signal? If it's high (like over 10%) this will eat your battery, so you'll need to reset the radio by quickly going into airplane mode (hold power) and leaving airplane mode. TWS will drop quickly. Weird bug, you'll have to do this once every reboot, hope it gets fixed.
Also, if you are in an area like work or home that has wi-fi, leave it always on, turn off "notify open networks" and hit Menu / Advanced to switch the wi-fi policy to "never sleep". When you are at home or work the phone will auto connect to these places and do all data over wi-fi which uses less power than 3G, even when the screen is asleep.
Finally, while I leave on window animations & Google Talk, I turn brightness in the browser and on the phone all the way down and turn off haptic feedback except for the capacitive buttons.
I've been unplugged since 8:30am and have been at work & home and texting all day, light surfing, a few phone calls, apps, etc, and now at 10pm I have 65% battery remaining. I think that's pretty good.

Wha?! All that and still 65% by 10pm? If I let my phone sit on the desk from 8:30 am by 10pm I would probably be less than 65%.
The range of experiences is just way too wide on this board. I like this phone so much that I've decided to just accept it drains battery and have chargers everywhere. Plus I have 2 in my house purchased in different stores that exhibit the same power consumption.

You wanna explain this to me? Do you mean ALWAYS have wi-fi enabled? Or just when I'm at home? I use wi-fi at home for both the better battery life and faster speeds, but I was under the impression that if I always had it on that it would always be searching for signal, thus being entirely counterproductive.

This. I don't have all the chargers yet, but come Friday, I'll have two house chargers, an extra computer cable (for school/work), and my car charger. This phone is too awesome to let my battery life ruin it.
I've noticed that web browsing kills it fastest, which wasn't a surprise at all. I usually get 8-10 hours out of it, which is a lot lower than desired, but something I can live with. At least if I get my chargers, I can save the overall life of the battery.
Another thing to mention:
Vibration, while convenient and least annoying to everyone else, is the most power-draining notification you can use. Next is audio. Last is silence (obviously). Having it make noise AND vibrate is like signing your battery life's death warrant.
i think hydralisks epic runs on fairy dust and unicorn blood bc my epic sucked battery like no other.. and thats...screen brightness at 0...no programs running at all. and it still said 77% of battery drain was from the display. lol
+1 yeah battery life does suck worst than evo I rebooted phone once and it was at 40% came back on at 2% had similar problems with moment just have to deal with it juicedefender does help overall its horrible

First one reads: 21 hours and 29 minutes. For almost 4 hours of that, the screen is on. So you people saying you get 5 hours of battery life are doing something very wrong... or you have a bad phone. I can easily surpass 4 hours battery life with the screen on the whole time. Some of you don't seem to realize that once the phone hits 10-15%, it takes a LONG TIME to get it down to 0%. This is probably due to the battery just not being calibrated yet. At 6% battery I actually had to watch a whole hour of movies to get it to 0%... and even then the phone did not shut down.
Edit: phone was in airplane mode because the battery was at 0% and I didn't want it to crash before I snapped the photos. Cell standby is a major killer of battery. A solution to that (if you have a large cell standby number) is just to toggle airplane mode on and off when you boot up your phone. It works... dont know why. By my cell standby is almost always down to 5-10% now. More info on this issue here: http://forum.xda-developers.com/showthread.php?t=772571
i agree with hydralisk, try toggling the airport mode on and then off. it will reboot the antenna of the epic. the cell standby mode totally drains the phone's battery reguardless of user activity or not. mine was 51% without signal but after the airport mode toggling, it dropped down to 8% without signal and my battery is somewhat better. (i'm a hardcore user so 8-10 hours is awesome for me. haha)
I can say that my first Epic was a bad phone. It wouldn't even last 3 hours on a single charge! It would discharge while browsing amazon.com and bn.com using the built-in browser and while plugged into the AC charger. I thought I was seeing things.
Today, I've exchanged it for a 2nd Epic. It still does discharge when I'm pounding away on it even though it's plugged into a USB charger. But otherwise, everything else is looking at lot better now, especially AC charging.
So there are good and there are some very bad examples of the Epic out there. I believe I've personally had my hands on both kinds.

I'm getting great life with the latest rooted kernel by noobl. 5 hours and phones at 98% medium usage
i am getting similar hours to hydralisk.
i love this phone! it looks like there may be a few bad apples in the bunch, but i hope everyone else who got a good phone is enjoying it as well!
Alright so, I know people frequently post pictures of their battery life "Unplugged for" screenshots.
So I'm wondering, whats the longest we've seen, with atleast 2 and a half hours of display on-time?
And what ROM/Kernel were they using?

Oh my bad man.
I'm running Baked Snack 1.5 ROM with HeroSpecial#2 kernel right now.
Its still at 5% and currently 2d 19h 14m. Could prolly get 3days to read on there if I felt like it.
I have to say I'm getting amazing battery life with Baked snack 1.5. I had the phone running for one day and 18 hours, I spent about 3 hours on the phone and using it constantly to check messages. I'm very happy with my phone.I'm installing 1.6 now, it should make it to two days. I had WIFi on all day.
2 hours of display on time over 3 days? Anyone could get ridiculous battery life if they never use the phone.
The ONLY way to compare battery life semi equally across various roms/kernels/settings and setups is to restart the phone, turn off the display, leave it for several hours without using it at all, and measure what the %loss per hour is for a completely idle phone with no use. The longer you leave the phone idle, the more accurate the measurement of % loss per hour will be. We can then compare how much power various setups are using in idle as a baseline.
Anything other than that is open to people messing with their phone or turning on airplane mode or never using it and claiming amazing battery life.

First, that was my normal use for those two + days, didn't have time to use my phone other than for texting and such. And if your a texter, than you know it only takes 20seconds TOPS to reply a text message, and texting is a majority of what I did with those two+ hours. so we'll say 1:45min of it was texting.
20seconds of on screen time per text = about 315 text messages, which is about what I did.
To me that is great battery life, if I can get that much battery to do that than I'm happy.
As for the way you stated, I guess this counts:
When I slept, I slept for 8 hours and some odd minutes and lost 3% the first night and slept I believe 6 hours and lost 2% the 2nd.
I guess that would mean 3hours idle = 1% battery drain judging by your method? Idk. Lol.

And if your a texter, than you know it only takes 20seconds TOPS to reply a text message, and texting is a majority of what I did with those two+ hours. so we'll say 1:45min of it was texting.
20seconds of on screen time per text = about 315 text messages, which is about what I did.
To me that is great battery life, if I can get that much battery to do that than I'm happy.
As for the way you stated, I guess this counts:
When I slept, I slept for 8 hours and some odd minutes and lost 3% the first night and slept I believe 6 hours and lost 2% the 2nd.
I guess that would mean 3hours idle = 1% battery drain judging by your method? Idk. Lol.

Ummm I don't even see why you need this phone if all you are going to do is text with it. There are so many other phones that are smaller, lighter and way better on battery if that is all you do. The LG rumor 2 comes to mind.

Meh, I guess since Baked Snacks thread got closed, none of you saw my post in it before it was, stating why I wasn't using my phone much -.-
I was back and forth to the hospital all this week, no time to worry about charging my phone and no time to use it much other than quickly texting. My grandmother is in there but thats a personal note and doesn't relate to any of this.
Anyway, point is, I wasn't able to worry about charging my phone much, and I was impressed that it made it through all that without dying on me, I was planning on not having a phone for a day because I knew I wouldn't be charging it. Thats why I was impressed.
But thanks for the suggestion of yours. I'll be sure to write it on the next piece of toilet paper I use.
And can we please get back to the original reason I posted this thread..?
Nobody has mentioned the best battery life they've seen on the epic.

Well that seems like some good battery life if you only lost 1 percent every 3 hours. Airplane mode? juicedefender?

Whats the normal drainage for idle phones?
Neither, I just turn 3G off and force roam it at home with Roam control because I get 1-bar while roaming and 0 bars with Sprint coverage at home so roaming helps the Time Without Signal a very little bit, on sprint it runs at 99% without signal at my house and on roam it runs at 80-90% without signal.

I get a little under 1% an hour when idle usually. I would have to check it again tonight to see what I am currently getting. I am using phoenix 1.43 and EE 1.2.03. I use juicedefender and disable drm and toggle airplane mode and all that nonsense.
i'm curious what most people are getting for % battery loss with screen on. i feel like mine tends to be high across several ROMs and kernels. its varied somewhat of course, i've used AOSP magic, EE, Syndicate and on baked snack 1.6 now. my numbers show approx 1% battery loss for every 2 minutes of screen on. so that would only be 3hrs 20min of screen on time total which is junk, lol. anyone else got reports?

First, there's just way, way, WAY too much pissing and carping that goes on around here between people about their different usage models.
We each use the phone the way we use it. If you hardly turn it on, you'll get awesome battery life. If you use it like a combination phone/PSP/iPod/Nuvi all day long, you'll get horrible battery life.
I fall in the latter category. I use my phone for business, so I talk hours a day on it. I use it for navigation in the car. I watch probably 2+ hours a day of video on it in the evenings. I listen to music while I'm out and about. I play games when waiting around (like in the doctor's office).
I do all of this usually with wireless bluetooth.
So, I'm happy if I get 6-8 hours out of a full charge, which is rare. However, it's not because the Epic has a crappy battery or sucks juice... It's because I use it to it's full capability throughout the day, every day.
That said, muyoso's point is spot-on when it comes to comparing battery hog/waif in terms of ROMs and kernels. The only thing that matters is non-use. A setup should be very stingy and sip electrons when nothing's happening. Under interactive use, there's little to nothing a dev can do to squeeze more life out of 1500mAh than, well, 1500 mAh.
I've been running Syndicate 1.2 for 24 hours now, and I can say that when the phone is idled, it's far more stingy with power than the stock ROM. The latter drank milliwatts like it was weightlifting when it was asleep and nothing was going on. Syndicate seems to barely be breathing at all when the phone's asleep -- just how you want it to be.

Because of how an AMOLED screen works power usage will vary greatly depending on brightness setting. So, taking care to adjust the brightness to suit viewing conditions regularly can make a big difference -- or use auto brightness.
I don't think the latter does a very good job, and I don't like it surprise changing/adjusting while I'm using the phone, so in all my anal retentiveness I constant adjust it manually to suit me.
Thank God for the nice notification-bar-finger-slide-brightness feature that Sammy added.

Hey, if you guys can engineer a fix to the incredibly stupid non-mixing, single-audio-source idiocy of Android's audio subsytem, I'll give you a very generous donation. I love almost everything about my Epic and Android, and haven't looked back wistfully to my WM Omnia II until I noticed this... Can't believe Google botched something as tecnically simple and unchallenging as this.
I mean, really... there's public domain, GPL code out there that could have just been plopped in to make a barely decent sound subsytem. It's a crime that my music mutes every time I get a notification about an email, SMS, etc.
The only solution is to disable sound notifications, which I've done. I can easily live with that, but I shouldn't have to.
One thing the ACS team might consider is adding an option to disable sound notifications when certain apps are running, like media apps playing music or video.
I think for most, if you just root the phone, disable the DRM, and run a program like Setcpu it will make a dramatic difference. It did for me. I just set SetCPU to throttle down when the screen is off.

That is 36 hours since a last charge and counting with 39% battery left! during this time I have been using the internet, a few apps, the camera and XDA forum app!
The lowest the Play has latest me is about 7 hours but that is playing 3D games non stop, so anything pushing the gpu will drain the battery a LOT faster than shown above.
So yup, the Play has got a FANTASTIC battery
UPDATE: So far it has lasted 40 hours 8 minutes with 18% remaining
Update, 43 hours with 13% left
Damn i'm jealous. My play doesn't last that long. Did you disable some app's? Ans all sync on manual probably

I've got about 150 apps on my phone, Trillian constantly running to keep me online with IM protocols, syncing set to automatic, streaming podcasts with bluetooth and playing games from time to time, often with the screen on for long periods of time. I've been averaging 24-35 hours per charge, FAR better than my old Captivate which wouldn't last a day at any point.

Mine is rooted and I removed a few system apps, nothing major though, I have facebook and twitter syncing every 3 hours, email every hour.
My Play finally turned off at 2%, total time - 45 hours, 7 minutes
I have been using a lot this afternoon so did go down faster during the last few hours, highly impressed as my old samsung galaxy s would never last a day without a charge.
Yeah, I think it just depends on how you use it. For me I don't use 3G at all so that already saves, and then on top of that I selectively turn on/off bluetooth and wifi. I can game for like 3 hours straight and still have 75% left. I think the longest I've gone is 24+ hours with heavy periods of gaming throughout. If you constantly use 3g, wifi, bluetooth, and have a gazillion programs running then ur battery life might be way less.

This is the thing, On the other end of the scale I have only got 7 hours out of it when I was playing games non stop all day but that isn't bad as my old psp would go flat in 3 hours playing non stop.
It definitely depends how you use it but its good to know it can last for almost 48 hours between charges if you want it too!
Hello FK1983, thanks to your post I found the Battery Monitor Widget, which provide more information than the one I had before. I was reading all the post about the xperia play battery because mine was lasting just for half day.
I install this widget and noticed that where it provide the estimate charge use by the phone was showing more than 150mA, this even in standby, while yours was only showing 4mA, base on this I know somethign was running and eating my battery so I restart the phone and now it has been in 2mA while in standby and around 40mA and 60mA while writing msg or checking something else.
Is there any way to know what is eating my battery if I notice the last behavior again? so i can just kill it and not just restart the phone again
Another thing I noticed is that in your picture where you can see the battery information it says "Techno: Li-poly 585/1500mAh" while in my play says "Techno: Li-poly XXX/1200mAh" where XXX is the actual battery charge. Is this indicating that there is something wrong with my battery? I check it just to be sure that it wont be a 1200mAh battery model because of different region market but the battery has written on it 1500mAh. Any help will be appreciate.
Thanks.
Always check to make sure Gtalk isn't running in the background if you're on 3G (make sure your signed out), as it literally destroys my battery in about 6 hours.
And if anyone knows of a precise application that indicates battery usage (outside of the built-in one), I'd love to hear about it!
There's no question that the play has great battery life compared to most smart phones out there. I lost my charger and it lasted 4 days and still wasn't dead when I bought a new one.
any tip?
is a good time in u battery....

The battery mAH settings you can change from 1200 to 1500 in the options, that maybe why some of your stats look different to mine? give it a try.
Regarding running apps, you could keep a close eye on the running processes and see what is running there, or use a task killer or even an "app monitor" that records apps usage.
Folks that report awesome battery life:
Have you applied the 2.3.3 update? I'm still on 2.3.2, and I'm lucky if I get 5 hours of moderate internet browsing before needing to plug in (with about 20% battery left).
Also, in contrast to the OP's picture, my battery widget is consistently reporting between 200 and 300 mA shortly after a reboot. Can't kill any tasks to speak of either. Nothing is running to speak of except homescreen widgets.
Using launcher pro with its built in facebook widget, power control, fancy widget, pandora widget (not playing), winamp widget (not playing), battery monitor widget, google plus widget, and a volume control widget. Running a live wallpaper as well. With all this running, is 300mA a reasonable usage?
I'm on 2.3.3. 5 hours seems awfully short for just web browsing...
I get around 24 hours with 15 hours of Facebook & ebudddy....around 2hours of web browsing and abit of gaming
Sent from my R800i using XDA Premium App
Im on 2.3.3 and i get around 24 to 30 hours facebook and surfing the web for around 2 hours and sending msgs and making some calls. if you are getting 200 or 300 mA i think something is killing your battery. On idle Im getting around 4 and 5 mA sometimes 12-15 mA(I guess something running in the background) and when using the web browser, WIFI on and GPS on im getting around 100-150 mA the most being really bad.
I'm on the R800X. I guess verizon really screwed this phone up.
I rooted my play last night and my battery seems to drain quicker.
I don't know why I havent done anything to phone yet as iv been at work all day. And since I havent replaced all my games yet iv used it alot less today than I normally would but the battery seems to have drained more than usual.
Would a task killer help prolong battery life? I read somewhere that a task manager is not needed with android but im skeptical

Android has a build in task killer, having two will only drain battery. try setcpu and remove as much bloatware as you can(need root).
I just updated my play to 2.3.3 and battery life seems worse for me than 2.3.2. I can barely get through a day of light usage (no gaming, and ard 1 hr's worth of web surfing, switched off most of the updating from apps like facebook, email, pulse etc to manual).
I tried battery monitor widget and my Battery health shows up to be 'null' (my friend's htc desire hd shows 'good'). Would any kind soul be able to tell me if there's something wrong with the battery or the software (mine is stock Singapore xperia play firmware 2.3.3).
I'm running Toxic Crazy8, stock battery, Bali Kernel, undervolted an extra -25v across the board, reduced clock speed to 400mhz when screen's off. Light use gave me 44 hours of battery!
I probably could have pushed it even further. The first night it was updating 35 apps over wifi, and that sucked up almost 60%

That's great an all but it comes slow. Try multitasking or play a simple game. It will lag like crazy. 44 hours is too much anyway, for me 12 hours would be the best.

I got 48hrs from the same rom, with wifi on constantly with skype. light to moderate use. Music at least 2+ hours twice in that span as well. Great rom. I chose not to UV or overclock so I have no SetCPU or anything installed, it's stock toxic with the 98 kickass script and v6. Really fast actually and no need for oc.

thats impossible with "moderate" use.
its light, and i mean like.. VERY light not even to the scale of being the actual light... so techinically your not using light, but using little light to no light at all.
P.S. my sentence includes 6 words "light"
now that i'm done with that bull****.
Please people posting their batteries as 40+ hours, PLEASE start using your phone. or just get a feature phone, honestly.
I, too, keep my phone on standby more than actual use, but i DO use it when i can. theres atleast 8 hours of music daily, constant wifi use, 24/7, and i get near 20 hours of battery life because i consider my use minimal moderate. At the end of the day, my battery life is usually at 40%, then i charge it again.
I'm on MIUI as well so battery life isn't perfect and i can deal with that.

I SAID "light to moderate"... Also how can one judge what moderate is vs moderate with a guy who acts like a girl being on the phone all day texting and talking??? It's a ridiculous to even judge moderate or light vs someone else, because everyones concept of light to moderate are vastly different. So don't come at me like that bro.
Light to moderate (hence i didn't use strictly moderate) to me is at least 1 and a half hours on skype calls, at least an hour and a half on calls, a few texts on skype and sms, 10+ emails, a few show-offs lol, Wifi never turned off and skype always signed in, at least 4+ hours with music at the gym and a little after, a few random checks, a few market and web browses and maybe a short vid chat. That's light to moderate to me.
If you want to see less than light, like when I'm sleeping and checking my phone occasionally with wifi set to never turn off and skype signed in always I'll show you. It's been almost 12 hours since i was at full charge and unpluged and I am now at 94%. seems ridiculous I know and I thought so too but I ain't complaining. Stock battery as well. I'm no way saying this is light or what have you because it was idle for 90%+ Just an example of how deadly toxic 8 is with battery. And I do have apps. I dont usually play games though.
look at the attachment.That was after I downloaded 2 apps and tried them both lol and couldnt figure out how to screenshot. I'm done with this "bull****" now.
Once I see the cell standby is higher than the display I pretty much know how you use your phone.
No, you only know what you see. I am running Toxic8 also and am getting around 30+hours of real actual use, granted 8 of those are when I am sleeping, but still get strong use all day long.
Day in my battery.
Get up and go to work at 7am, listen to Iheartradio until 930-10
PowerAmp until 130 lunch with texts and email checks throughout.
130-2 XDA, random surfing
2-6 I listen to 2 different podcasts.
6-7 ride home on bus and listen to PowerAmp and check XDA again.
9-10 after kids in bed and I play a few games and check/clean some files in
Root Explorer.
Go to bed and then start over in the morning and finally plug in around 10 or 11 (lunchtime)
The cycle may shift a few hours here or there but it almost always the same. Oh and not sure if it is this ROM or not,but if I go into settings>about phone>status>batteryuse the picture shows that my display is at 75%, stand-by is 15% and phone idle is at 10% all +/- and that is clearly not the case. So you think that you see what my use is like but really you aren't.
I also use Juice Defender Plus which kills the radio/data traffic for an app-to-app basis and I have it set to kill radio/data while I am asleep.
I can post a screen shot if you like of the battery use (seeing isn't believing) or a shot of BetterBattery Stats (seeing is believing) if you like, but I am using my phone all day AND getting 30.
my vibrant hates toxic 8 for some reason. ultimate rom on the other hand has been very fast, responsive, and long lasting.
I prefer to actually use my phone for what I paid for it to do.....if I just want a phone ill go buy one out of a gumball machine or pick it out of a box of cracker jacks

I was at 19 hours and 31 minutes using the Stock ROM with 41% battery left.
That's 33 hours if I had let it go all the way down with the same usage, and I definitely used it more than the OP does if that screen shot is any indication.
Didn't use airplane mode or anything.
I just uninstalled all apps I don't use and use a Black Background with only 3 home screens and a 30 second screen time-out.
WiFi used whenever I could, and I keep GPS on all the time now. Automatic screen brightness, too
The people who are being negative, what do YOU consider good use? I'm on trigger 3.2 final with bali 1.8.8 kernel, and my phone can get 24 hours with occasional use and still be at 50% battery, easily 24 hours with REAL use.
Real use includes calling for 1-2 hours, playing at least an hour of games, and just syncing off for apps I don't use constantly.. I don't have the phone underclocked when screen is off or undervolted any more than the kernel is set for.
How do I get that battery life? When the screen is off, it is in deep sleep. I get less than 1% battery drop per hour when it is in deep sleep. So basically unless I'm ACTUALLY using my phone, it isn't draining.
The part that impresses me is that I get easily 20+ hours of heavy use on the ORIGINAL battery(over a year and a half old). I know that battery must have lost some of its ability to charge.. I got my phone replaced by warranty, and the battery they included WILL NOT give as much battery life.. it makes me think that the problem with some people is a combination of a crap stock battery, and wake lock issues..
Wow this is some crazy stuff! I've been on GB for a long time now. I was just thinking the other day to flash back to 2.2 just for the lulz. But then along came the ICS port.
It seems I should try this out.

2.2 toxic is a great rom. i think it doesn't get enough love because of the GB and ICS options.
either way even 12hrs of battery life is pretty nice congrats
What I don't understand is:
1. How come it's on flight mode?
2. How come Display < Stand By?
Running on stock 2.2 with 3G, WiFi, Bluetooth, and GPS turned off, barely any apps installed so nothing started up in the background, and not recieving any calls all day my battery went from 100% to 93% in 13.5 hours. I estimate just shy of 60 hours of potential battery life.
But that was with a phone that wasn't being used at all; i.e. a paperweight. I could just turn the phone off and claim I had a bajillion hours of battery life.
FYI when I took the sim card out of my daughter's iPhone 3G, turned off wifi, and shut the screen off it lost about 1% PER DAY. That works out to a 3-month battery life (give or take) but again it's just a paper weight at that point.
In other words, if you're using your phone as an MP3 player for 2 hours a day, why shouldn't it get 44 hours of battery life?
Ok so i read all this hype about crazy8 so im trying it out now...
Damnit im very impressed....
I watched 2 movies complete played angry birds, on my phone for most the night and this morning when i got off work 9 1/2 hrs later i still had 35% battery life.
That is awsome to me,though i did not get 44 hrs due to i actually use my phone i will say im impressed,,,,i now no longer need to carry my 3 batteries and the external charger with me everywhere i go lol
I normaly go thru 2 battery changes a night.
Tonight i will run with all the script tweeks and so on...im excited to see the results then lol...although i will not run plane mode and undervolt it and all those lame tricks, actually may oc clock it a bit.
No more miui and cm7 for me lol bad ass battery life with everything working and snappy as hell....im at home with crazy 8
everybody,
I am totally new on here. It is the first forum to pop up, when I was searching about battery for Galaxy S7 Edge.
So here is my problem... I bought my S7 Edge 6 day ago. That is 1st of september. I must say, that I tottally love it. Nice design, works good, beautiful.
But after the first 3 days of playing with it and tweeking it to my liking, I started using it more normaly... so not playing with it ALL the time. And I couldnt help but notice that the didnt get me throguh the whole day like it did on previous phone.
My previous phone was LG G3 and the battery was great for about year and half. Meaning, it survived till bed time (around 21-22 for me). But this phone was on 10% at 6 pm.
At first I thought it was because I did not charge it over night, but more about that later.
So yestrday I went on the internet and browsed a bit, and found that people usually get about 7hr of SoT with 20% battery left (with no power saving modes). Well mine had 4hr 50min SoT and 15% battery left (23hrs total use)... doesnt seem normal at all.
So yestrday when I got home I plugged in my phone and started browsing about this... i was online till about 3.30 am and that is when I UNPLUGGED my phone. I only went to set the alarm clock and in the first 2 MINUTES after unplugging it drained to 97%... "Okay", I said to my self and went to sleep. This morning I woke up to 93% battery (i slept about 6 or 7 hours so normal drain, i guess)... i had the night watch on and i also have aod on. Anyways... I thought that all is good and i went to get my coffe and went to check something on youtube and I didnt even start the video and it drained for 1%...
So I decied to post on here about my problem.
Now bare in mind, I woke up at... checked the battery... went on youtube...saw that drain...decided to post here and i have been typing this post on my s7 edge...
I have 40 minutes of SOT and it drained from 93% to 83%...right NOW. That is 10% in less than an hout of only typing a text on a forum... many people reported that they were on YouTube for a whole hour and lost about 1-2%. And here I am typing on forum for less than an hour
All I currently have on is 4G (LTE) and Chrome browser to type on this forum. I have AOD on but its not in use right now since I am using the device.... also auto brightness and 3 bars of signal.
Now tell me is something wrong with me or with my phone? I dont get it. Should i go to my provider and get a new one? Do you think this one came with a bad battery?
Should I go to my provider and replace it?
I dont know what to do and I hope you will be able to help me. ((
As i Finish this post, i am left with 82% battery... i think even my LG G3 lasted longer to get to 82% and its 2014 phone with 3000mAh if im correct.
Thanks for your help guys
Oh also I am sorry if I posted in the wrong section. Tell me and I will do my best to find the right one.
And also what I should mention is, that I have the Exynos version.
Another update.
So after i posted, I deliberately went on youtube and was watching videos for a full one hour and few minutes on 4g data. And came from 82% to 71%.
My current battery stats are:
Total time: 2hr 8min
SoT: 1hr 55min
As i am finishing this post i have exactly 70% left.
So here is my report i hope you can help me as much as ppossible, if its normal or not, if i should replace it or not. I just think that based on report of other my battery os worse. Some people have like even 1day 14hrs total time and a crazy 7.5 or 8 hrs of SoT.. mine was tops 1d and sot of almost 5 hrs... and well you can see from my forst post how it drained...
Hope i am not complicating and over reacting but i want to get the best out of this phone for the money i spent
And another update.
I talked on phone with my friend, who has LG G3, for 40 minutes.
It drained my battery from 69% to 63%.
It is funny because in the exact same time his phone also drained 9% of battery. Thats why i called him actually. And it shouldnt be like this. Cause his phone is older and has a 3000mah battery... so how can consumption be the same?
I don't know your usage pattern my friend or how is cell reception quality in your area, but I can tell you that your battery life will only get better after a few days/weeks.
Android will settle down, learn your usage pattern, optimize apps that use battery in the background but you never use, etc. Your battery too, chemically, will hold a charge more efficiently after a few charge cycles.
I've been using my Galaxy S7 Edge for 2 weeks now (with a custom ROM/kernel though), and I got 6h54m of screen-on time yesterday (auto-brightness) when I went to bed (15% battery left). That's something I've not seen since my good old Galaxy S3.
Give your phone some time to settle down, cache the stuff it needs, etc.
Thx for the reply.
Well I have around 3 bars of 4g signal in my area.
Like I said I have had it since last thursday. Ive been using the phone since 10.30 and its 14.08 now and i have 59% and i have 2hrs 15 min SoT. (Total time around 3hrs).
I really do hope it will break in,settle in, chemichally like you said... because right now i feel its same or just a bit worse than lg g3 i had last week (which was 2 yrs old). And that is not logical to me, that a new phone has same battery stats as a 2 yrs old phone.
What were your stats the first week or two and when did it start settling in and getting better?
4G + YouTube for one hour and You only lost 11%? Your battery is really good. Also 40 minutes of call and 6% drain is once again really good.
Usually using 4G for internet and calls or videos drains battery unbelievably quickly. I get around 5:30 hr SOT with a custom rom and a custom kernel but only when I have WiFi only without 4G enabled. With 4G I would probably have like 2-3 hours of SOT if not less lol.
I've had many phones, chinese, low end, mid end, high end, iPhones. And so far S7 Edge has the best battery. Even some of those phones had a 4000mah battery and were really power efficient, but they still had worse battery life than my S7 Edge.
The results that You have are really good. Nothing to be worried about. Replacing battery might only give You a worse one or a identical one.
Edit: Just checked and G3 has 40-50k antutu benchmark score. And (my) S7 Edge 146k. It's kind of obvious that it will drain battery a tiny bit faster. Other than that display goes there too or even things like better signal(4G module) boards that take more power but still give You better signal in some situations.
I think that you are overreacting. Your battery life seems pretty good. It will vary for everyone and is really dependent on usage patterns. 7-8 hours of SOT is an absolute best case and not many people will actually achieve that. Most people will fall in the 4-6 hours of SOT with normal use. I typically get 4.5 hours of SOT and 28-30 hours total.
Edit: I have gotten over 7 hours of SOT once, when I was at home all day playing games on my phone. Also, the Exynos processor version seems to have better battery life than the Snapdragon version. Which one you have is based on location typically.
Thanks guys! Thank for comforting me. I feel much better. I guess many of those reporting those crazy SoTs are in reading news in a dark room lol.
Well i have 40% left. But i was literally on my phone since 10.30 and on 4g all the time (except that phone call, during calls i disable it).
Otherwise I am really,really happy with this phone. When i bought lg g3 i had a bit buyers remorse... with this one i have mone (although lg was phenomenal!).
Also if someone withi same worries will read this... i noticed that stock browser is faster than chrome and it drains less batrery than chrome. So I will try to get used to the stock browser, also for something new, cuz i have been using chrome for ever now.
And it also has fingerprint to log into sites (stock one)
Last update on this charge.
Right now i have 4hr 40 minutes of SoT. And 20% battery left. I enabled battery saver at 25%.
Total time of battery is almost 16hrs.
And i have to say that at around 14pm i was browsing on chrome for like and hour or maybe 2 hours and id say thats pretty heavy for the device. On chrome which eats ram like dragon.
Thanks again guys for helping.
But still nothinf compared to those guys that are getting 6hrs or 7 or even 8.
Thats like 2 to 3 hrs more than mine. Either they are having all functions turnes off (smart capture, edge feed etc) and brightness to lowest possible...or my i am doing something wrong. Haha

Chrome is a ram killer on every device. Mostly Windows.
For now I have a 5:30 hr SOT (today) but with some battery saving tweaks(custom kernel too) and WiFi all day.
Like I said Your battery is pretty good cause my phone with 4G enabled would get not more than 2:30hr SOT. Maybe my carrier has poor signal and the phone needs more power for antennas to see signal. I've no idea.
I also think there's nothing wrong with your battery, I usually get around 5 hours of SoT, right now I habe 5 hrs 12 min of SoT and it's been 16 hours since last full charge, also I have 32% left, It's about the best usage time I have ever gotten.
The difference may be that today I turned the gps off and set the auto brightness.
People reporting over 7 hours of SoT are most likely using a custom Rom or custom kernel, or apps like greenify to hibernate apps and background process.
I used to have a LG G3 before this phone and the battery was anything near this momster, and has been getting worse over time, now it barely last 2 or 3 hours of SoT and the pone gets reaaaaally hot.
I have read that the battery seems to last longer if you dissable the quick charge option.
Btw, while writing this my battery drained 1%.
I see that you came to this forum by clicking the firts link that came out in google, well lucky you, this is one of the best android forums out there, most of the greates achievement in android have seen the light here, give it a chance and you'll find a lot of help and information on here

Oh, one last thing, I strongly advise not to get your battery replaced, the phone needs to be oppened to replace it and it will lost its water resistant for ever

Well let me report again.
Yesterday I activated power saving at 25% and used it normally and tried my best not to plug it in.
I plugged it in at around 3 am with 2% left. Before that I was on 9gag and facebook and got around 1 more hour SOT. Before plugging it in I checked battery stats and I had around 23 hours total use, if i recall correctly and 6hr and some minutes of SOT, and I'd say I was pretty hard on the phone yestrday with all the youtube and 4g and chrome browsing.
Right now i have total time 2hr 36min and sot 1hr 33min and im on 80%.
I feel better now that you guys told me its actually pretty good battery and I thank you for that!
Btw do you guys suggest any apps that kill background apps that i am not using? Or is samsungs system pretty okay in doing that? I never really used app killers on any phone before.
Thx
Oh also, i have to say that i use location only when i need it. And also wifi and 4g. BT always off also NFC. Most of these are off...they are on only wheen needed. And i have almost all advenced functions turned on (AOD, Night watch,smart capture,direct call etc...) i really like them and i use them. And they are awesome, so why turn them off. Im saying these because probably some sensors are needed to be turned on to and this drains battery.
But still i am happy with the phone and battery,especcially now that you guys told me all the good stuff

I'd say that process/app killers are going to make Your phone less smooth. Your phone caches the apps in the background and this way it launches them 2x as fast. And some apps when You clean backround processes will pretty much restart themselves immediately and slow down Your phone
I could only advice You to clean cache/apt cache every month. That should give You more space and refresh Your apps. But even if You were not going to do that, Your performance wouldn't be slower anyway .
This phone is powerful enough to run windows xp at a decent speed(tried it out yesterday) and it has a lot of internal code that makes sure that everything is clean and smooth.
I guess that this is how S7 Edge works. Yesterday I was 50% battery left when I went home after working. With my note 4 I left the office with a 75% battery full. Thou I dint have AOD in the nothe 25% battery for that it seems too much so I installed several xposed modules and from today Im testing batterys consumption. My note didnt have LTE to I will check the % used with LTE, tomorrow Ill test with 3g and comapre the results, maybe LTE requires more power. Also, after this tests Ill disable AOD and Ill test it again...

App killers are really a bad idea, in android free ram is wasted ram, the phone uses more resources to start the aplications again everytime you need it, it is far better to have them loaded in ram so they can open faster and with less effort to the phone. Android manage ram and background apps based on priorities defined for every app. just let the system handle the ram on its own and it will be fine.
You can, however, use greenify to hibernate (not the same ass kill) the apps running on background, that way they stop consuming resources untill the app is woken up by user or other app.
In general, any app or wakelock that prevents your phone from going into deep sleep are the main causes of battery drain while the phone is idle.
You can search on this forum for a guide on how to use greenify along with amplify to obtain almost 0% battery drain while the phone is idle, but you going to need to read a lot.

Update:
Today for the first time I got 9 hrs of SoT
I think is interesting since the only different thing I did was turn the gps off and ser the auto brightness at 50%
Could it be that after a month of use the phone finally adapted and is managing the energy better?
I think 3 hours more of SoT than usual just for dissable the gps and set auto brightness is too much.
I hope I can still get this amazing battery life in the future
