Perfect Phone except for battery

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 .

ATT - battery just isn't cutting it

No matter what I do the battery will not last me a full day. A full day for me is about 18 hours. I use my phone almost none at all while at work and I use juice defender to keep data and wifi off while I am not using the phone. I would say 80% of my day is wifi and only a little is LTE. I monitor my task usage and the only thing that ever shows up is screen...there are other apps but very little usage. I use auto brightness. Could that be it? Unless JD doesn't work well with these phones, I just can't figure out what it is. Unless of course its just normal...
Phone has to last me 18 hours with moderate usage. If it doesn't, I need another phone.

Post some screenies?

The big killer of battery life is when LTE doesn't have a good signal (inside a large building). Connecting and reconnecting to the tower is what always kills my battery. I suggest you look and try those "turn of LTE" hacks around. My battery lasts me about 20 hours with moderate usage (but I am always in a great LTE location), and about 12 hours with heavy usage.

As long as your signal (wi-fi, LTE, HSPA, whatever it may be) remains good, you should have amazing battery life. I often take my phone out for 16-17 hours between charges and have ended the day with anywhere from 60% to 25% of the battery life, ranging from light to moderate usage.
For me, an average day is on wi-fi for at least 90% of the time, but a recent trip I had to Chicago (LTE all day, no wi-fi) showed similar results - and that was with some more moderate use while traveling! Not sure if there is much you can do about your signal, but I know my last phone (Captivate) got worse signal in my pocket vs. on my desk. SIII doesn't seem to be having as much of an issue, but still something to consider if necessary in your case.

I live in Dallas and have great LTE.

I just copped the sgs3 today and have not put it down my batt isn't that bad. 8 hours st8 on it lol

OP, one suggestion I have...
What makes this phone a winner over my One X is the removable battery. I believe you can get a second stock battery for about $30, and I saw a charger and battery for around $40 earlier. Maybe you should pick up a spare? I realize it's not ideal, but it's an option.

I'm in Vegas, lte rocks and I use my phone constantly. I can't get 4 hours so I just ordered an Anker 2200mAh.
I'm not on wifi but the Lte network in Vegas flies too which is just an additional $$. I've just got juice defender ultimate. I know a lot of people swear by it but I can do it better and faster myself. I'm a heavy user and if we could just turn off the Lte u and then maybe slow down the processor., I would be fine. It's ridiculous we still need additional batteries.
Whenever I leave my house I do the following in settings.
Power Savings I now just leave on.
I either completely Restrict background data or you can do by application in Data usage and go into Accounts and Sync and turn most off. Anything not Google is off and under Google I just sync my calendar, address and Gmail.
Now if we can turn off Lte, I will be fine I think.

I was running rom that was supposed to be stock but debloated and I installed the cpu1 sleep apk and I got horrible battery life. 5 hours and I was completely dead. I could not see any partial wakelocks. I was about ready to box up the phone and ship it back to Amazon. I flashed back the complete stock rom and I got great battery life. 12 hours, 3 phone calls, 3 push mail accounts, yahoo checks every 15 minutes, 1 hour streaming and the Windows Weekly podcast and I still had 65% left. I was moving so I didn't get a chance to browse or do work crap on it.
Hell with it, I'm staying stock till CM9/10 gets most of the bugs worked out.

I live/work just outside of an LTE area, and lately have been using my phone pretty light due to not being able to use it at work other than when I'm on lunch. I get almost no signal in my entire building, so 75% of the day I turn airplane on so my battery doesn't get raped.
So for me and my use recently, the battery has been doing good enough for me.
the standby thing raping my battery is weird,same thing with maps even though i never use it... but i guess both are common. Chrome use was at 3% and i forgot to check screen on time.
On the current charge I'm siting at 47% at almost 24 hours, about 1hr 15 mins of screen on time. 30 mins of voice, 10 of chrome...but i accidently unplugged the phone right before i went to sleep last night instead of starting this morning, and i just took a nap so again there is a lot of sleep time
Take all that for what it's worth, which I have no idea lol

I had the same issue, then discovered that going through a charge cycle fixes the issue. I got only 5.5 hours of use off my first charge (80% of the time on standby), but things improved enormously after recharging it to some extent, then unplugging it. See my post http://forum.xda-developers.com/showpost.php?p=28742643&postcount=297
I've had my phone unplugged for an hour now after the last partial charge, and it's actually gone from 48% then to 51% now, as the battery is still recalibrating.

Another Battery Question Thread...

Does anyone feel like their Note 2 gave them significantly better battery life??? I have the Sprint variant Note 3 and 2, and my note 3 after just 2.75 hours on time, and only being awake 4 hrs 20 minutes, is down to 62% already!! I have disabled so many things, what is sipping my battery?? The on time wasnt even gaming time, just web browsing or texting...
I used to get 10% out of every hour on for my Note 2, and would only lose about 3-5% overnight. Now Im dropping like 2-3% an hour, and couldnt even approach the 75 hour stress test that I read this phone could achieve.
Anyway, any help would be appreciated...

Check your apps, something is keeping it awake. Better battery stats, battery mix and battery in settings. One of those will give you your answer. It's not N3 vs N2, it's just apps. I get 5-6 hours on screen time at 33% brightness while always on LTE or wifi. Also disabling GPS, rooting, using greenify, will all help. You should give more info on what settings/apps you use.

Lol. I am getting at least 2 hours more battery life from note 2.

It seems that you would have to get it replaced or Sprint did something.
I got my Note 3 from TELUS Canada SM-N900W8 I have absolutely no issues with the battery life.
It is the best I have ever gotten, 2 Days EASY with light use, (I have many apps downloaded and most of my settings are ON except the old S4 stuff like wave your hand and other rubbish)
With Heavy gaming and use it still lasts me a day without a sweat, When I go to bed at around 11 AM I am still yet to see my batt life remaining under 25%.

This is true, no lie. I can Game heavy 3D games, 2D games, Kakao, surf the web a lot, take a few calls, send lots of text messages, do facebook and various others. and still last a full day.
If its light use its very similar with the guy above. Just strictly kakao/fb/whatsapp, web browsing. play with settings.
Plus the phone never heats up UNLESS I play intensive 3D games.

I have to agree...my note 2 was better for battery. Same apps...bascially same settings and usage is pretty predictable in my case. I never worried about battery on my N2...I just ordered the samsung battery and charge kit for my N3 if that tells you anything.
And i do have better battery and gsam installed..nothing really stands out as a batt killer.
Last night I charged both notes to 100 and then unplugged and left them
Note 2 dropped from 100 to 92
Note 3 dropped from 100 to 73
Again nothing stands out in the battery apps?

This is very similar to my experience. And this is my second N3. First was the same. I'm only getting about 4.5 to 5 hours of screen on time with less than 24 hours battery. N2 would get closer to 8 hrs on with at least a day...

With all sensors running, no bloat removed, I am getting above 7gr screen time with 24hr usage. On note 2, I could barely get 5hr mark.
Note 2 was great in battery until 4.1.1. 4.1.2 has dropped battery life a lot and this was the case with most people.
Now only problem with note 3 is that battery drains a bit overnight. You leave it at 100% and when u wake up, you could be at 95%. Is that a note 3 fault? Nooo, its the fault of 4.3. When I updated the 4.3 on n2 battery started getting worse on overnight. Actually in 4
3 Google services has started eating more battery.

With all sensors running, no bloat removed, I am getting above 7gr screen time with 24hr usage. On note 2, I could barely get 5hr mark.
Note 2 was great in battery until 4.1.1. 4.1.2 has dropped battery life a lot and this was the case with most people.
Now only problem with note 3 is that battery drains a bit overnight. You leave it at 100% and when u wake up, you could be at 95%. Is that a note 3 fault? Nooo, its the fault of 4.3. When I updated the 4.3 on n2 battery started getting worse on overnight. Actually in 4
3 Google services has started eating more battery.

Post your battery life info *stock rom only*

Hey guys, I'm using the iPhone 6 plus now and I'm seriously thinking about switching back to android. Just can't stand iOS. My only concern is the battery life since I got excellent battery life on the 6 plus. From the reviews every reviewer says it's very good battery life but I need to hear real experience from actual users here. How is the standby time? Screen on time? Please stock rom only and please post screen on time and overal battery screenshot. Thanks!!

Standby time? Lol I've been on it too much for that. Battery is excellent don't sweat the move from iphone.

My iPhone 6 plus has exceptional standby time so it gives me a feeling that the battery is endless. For example, how much juice does the note 4 lose overnight? (7-8 hours)

Bluetooth and wifi always on, pebble connected, poor coverage area. I keep it set to pick up lte when available, but I only have edge where I live. I travel a lot though and still get good life when I actually get lte. I haven't tweaked anything (yet). Be warned that my first charge gave abysmal life. It wasn't until the second or third charge that I started getting decent life, so don't worry when your first charge runs to nothing after 8 hours.

Amen. I use powersaving, and you could always use the ultra power saving in a bind.

Around 0 to 1 percent. Maybe 2 if I get a bunch of notifications. My fiance has the iPhone 6 plus, trust me my note 4 destroys her iPhone in battery. With light to moderate use I'm easily getting 2 full days ( I send roughly 500-600 texts, maybe 20 emails, at least 20 phone calls, navigate to appointments and I'm always on pandora....also I have a moto 360 connected all day). When I'm doing heavy usage I get about 24 hours or so. But my heavy usage is actually HEAVY. I can almost guarantee you don't use your phone more than me. You will be fine with battery life.

Thanks for the info!! I glad it does well with Bluetooth since I might buy a smart watch later. I intend to let Bluetooth and gps on,plus streaming a lot of spotify. Time to ditch the 6 plus.

Brightness at 50%. GPS on, Sync on, MultiWindow on.

Excellent battery life. I use my phone almost all day and night. FB, messaging, music, texting, phone calls, camera, reading, photo editing, youtube. I use it extensively on a daily basis during the week. On weekends I don't use it as much so I have more than half charge by Monday.

I turn on power saving mode at 100% when i go to bed, and when I wake up 5 hrs later I'm usually at 99% or 98%. Without power saving mode, I wake up to 96%.
I can easily get through a full day at Disney World (about 8 hrs) with light usage - mixed use of wifi and 4g, checking the disney app and checking my farmville farm, and checking feedly. I usually leave Disney with about 50% juice left. Brightness on auto, wifi on, bluetooth off, gps on.
I've tested streaming as well. On 4g, starting at 100% charge, I can stream about 4 hour long episodes on Netflix, on Plex it's usually a little longer than that before it hits 50%. At home on wifi, I can stream about double that amount before hitting 50%.
I'm pretty happy about the battery life, and the best part is I can always remove the battery if this one goes bad, or bring spares on trips. I can live with Touchwiz if it means I can have removable batteries, sd card, and the pen.

I've done multiple tests on this. I will charge it up at night 100% then leave it off charger for the night, look in the morning. I'm averaging 3-4% discharge per night which is not too bad. My Nexus 5 was a ridiculous 10-15%. Still nothing close to iPhone that just doesn't go down if you don't use it.
I leave all things on. Don't really want a phone that acts like a 2002 device.

Hey all,
Ok So My battery is at 23% with 4 hours 45 min of screen time and it's been of the charger for 1 day 20 hrs 15 min and 20 sec

The phone charge so fast and it is amazing. I dont know if I want to do that in the long run bc fast ch arging is bad on battery!
I have a nice battery charger and it says charging the battery slow will last longer per charge and longer life cycle itself too.
So what do you do?

I returned the iPhone and have used the Note for 2 days now. Battery is... Well, not as good as I expected. At least not comparable to the iPhone 6 plus. But I don't sweat on this since it does take quote some time for Android battery to kick in. I kinda wish Samsung didn't push the pixels since it's truly a battery drain. Also the GPS drains battery too. These 2 functions on the iPhone are very efficient.
And yes fast charge is wonderful. I say don't worry about the battery since it's fairly cheap.

Simple fixes.
1.) Make sure you screen brightness is on auto
2.) Put on a background that is dark, or mostly black
3.) Set your location to device only (GPS only)
4.) Turn the run time to ART
You will easily see an increase in battery life.
Below is my normal battery life. And an example of a good background to use.
Had about 5.5 hours of screen on time.

I actually switched from GPS only to power saving. I have quite a few email syncing tho. One interesting thing... Are you sure we should be on art? I heard its not fully compatible.

ART bogs down my phone so I don't use it. Also during boot up, it take forever to finish as it tries to optimize some apps every time. About 39 on mine. This makes my phone super hot and there's no way to bypass this process. I say ART is a bad idea.

Urgent question about battery (replace it or not under first 14 days?)

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
