Weak Battery Life? Post Your Battery Use Numbers

I am still not too happy with the battery of the Galaxy, even though it should be conditioned by now. Nowhere near as good as the iPhone 3Gs, even though the 45nm chip in the galaxy, as well as the AMOLED screen, should be benefitial to battery life.
Maybe a good benchmark would be to see what readings people get at the time of the first "Low Battery" warning. You can see what depleted your battery by going to Settings/About/Phone/Battery Use. To get details, touch the corresponding bar in the graph.
Mine are:
20h 32m 4s since unplugged
Display: 38% (1h 54m)
Cell standby: 24%
Phone idle" 16%
Android OS 10% (CPU usage 50m 4s)
Voice calls: 6% (2m 54s --- WTF?!)
Android System: 4%
K-9 Mail: 2%
Advanced Task Killer: 2%

Those numbers look good to me somehow, I wouldn't expect better battery life after using the display for 2 hours and another 19 hours of standby? Especially as the phone can easily stand by another few hours on the last 15%...

i just got my phone recently, i'll post my results after a few weeks of daily usage.
i do a lot of 3G+, WiFi and SMS, not so much voice call, but regularly enough like two or 3 calls a day
that should be a pretty good test to see how long the battery last from full to like 20% that's when i usually recharge my phone if i don't carry a spare battery with me

It depends on what you compare it to, I guess.
I am comparing it to my old iPhone 3Gs, which would last about 48 hours, usually with considerably longer talk time than the 2m 54s I have on the Galaxy S. How can less than 3 minutes of talk show 6% battery drain?!
As I noted, the Galaxy S's smaller die (45nm) and AMOLED screen should be an advantage over the iPhone 3Gs's older hardware, yet the iPhone lasts markedly longer.
Anyway, I just wanted to see what others are seeing and how long their phones are lasting. It might be interesting to many others, too.

The galaxy S holds considerably longer than the iPhone 3GS. Probably longer than the iPhone 4 as well.
My current stats:
2D 0H 33M 41S Since unplugged
Voice calls: 34% (38m 37s)
Cell Standby: 28%
Phone idle: 19%
Display: 18%
Funny, it doesn't show the time when i played SandStorm and Asphalt.
Oh, and my current battery level: 66%
If i skimp on the battery, i can hold 5 days between charges.

WOW! This is just amazing!
How long was your screen on for only 18%? (I have mine set at the dimmest, but still....)
Do you use email much and if so, how many accounts and often do you have the phone checking it?

Wait, you use tons of WiFi and you're suprised that the phone won't hold too much?
In contrast to the iphones that require you to manually search for a network, android ACTIVELY searches for local open networks and connects to them.
When you're not using WiFi- TURN IT OFF.
If you're talking about cellular internet, that's another thing.
And the display (set to medium-low brightness, the brightest mode where it doesn't BURN MY EYES. Damn this display is bright) registers 1h 27m.

For what it's worth, my WiFi has been off for most of the day.
But, on WiFi discovey, my experience has been the opposite.
On the iPhone 3Gs, I always had WiFi and BT turned on. if I was not connected to WiFi, but WiFi became available, the iPhone would bring up a pop up, asking me if I want to connect to the network.
With te Galaxy S, I can have WiFi Notifications on, but unless I search for a network (usually by turning WiFi off, then back on), it doesn't inform me of available networks.
To boot, even though it remembers both my home and office networks, half the time it does not sign in automatically when I enter the area, but I have to do the off/on thing to get signed on

Well consider yourself lucky! you got an amazing battery from the future or something, because this is not what we are all seeing... I get a decent 30 hours with mine max...

Can you tell us how long is the display time ?
My guess is that I could stay 2 days with my phone if I was never swithcing on the screen.
The thing is that you seems to use your phone like I was using my old nokia 6310 ...
Try to play some music or video and you won't last 5 days or even 2days ... maybe 1 if you are lucky
Basically you have left your phone switch off 2 days and call 38mn and that's all ?? I can't tell you that my old iphone3GS is going to be pretty close in term of performance of battery
given that 1h54 give 38% of 85% for the OP I would say that you have maybe 20mn of display

The battery life of my SGS was terrible for the first few days of use. I don't have the battery usage numbers but the battery would only last for around 20 hours doing: 30-60 min call, 2hour music, 30mins video, 30mins game, and approx. 40mins web surf using mostly wifi.
But after about 5 charging cycles (discharging until battery ran low and the phone eventually turns off, then charging the phone to full), the phone lasts for two whole days with the same usage described above each day!
So I have noticed a significant improvement in battery.
If you haven't gone through the charging cycle and your phone is relatively new, give it a week before you think the battery life is crap

yeah I am still waiting for the improvment
After almost 2 weeks , a dozain of cycle I still don't see it coming ...
I guess I must be using the screen too much ( miminum light) ...
Afert 12h46 I am at 25% with 65% taken by the display , 10% by cell idle, 8% by android , 6% by network idle, 4% by call ...
I have already used the screen 3h14mn
I don't know what you do but on my side I am reading my mails, reading xda, reading some newspaper on the train, watching some video ...
So my crappy battery doens't seem to come from some app draining it ... but just from the display.
So basically nothing I could do except using it less than what I am used to

Display time was 1h 27m

mine last around 10h (display on 4,5h) and thats as low as u can adjust brightness in settings according to gsmarena blog display can last up to 10h...
im using dimmer app now. hope i get 5-6h (display time) with that.

ok i'll play:
10hr:10min since last unplugged.
Battery at 74%
Display: 50% (I leave it on auto brightness)
Cell Standby:19%
Phone Idle: 12%
Bluetooth: 8%
NDrive: 7%
Android System: 2%
I'm happy with that.

I'm easily getting through a 15 hour day with moderate use (my normal usage pattern). this is on a par with my previous Nexus One and iPhone 3G.
BTW, I keep the WiFi on persistently (even when the screen is off) because I heard it draws less juice than the 3G/phone data. (I typically spend a lot of time around the house on WiFi ...)
Battery killer is normally "time without signal", the N1 would average maybe 70% without a signal, the SGS is averaging around 30% without a signal - so based on that perhaps the battery isn't quite as robust as the N1 (which was on Froyo).
Anyway, I have no concerns about my SGS battery based on similar phones and usage patterns. I will be tempted to get an extended battery for it though (I had a Mugen 3200mAh on the N1 and that would give me 2 days under quite heavy usage).

BTW, I keep the WiFi on persistently (even when the screen is off) because I heard it draws less juice than the 3G/phone data.

Are you sure about this? I thought I noticed much better battery life when I started to switch wifi off and using 3g instead. I guess it could just be my battery maturing

Keeping the WiFi policy to never disconnect apparently uses less battery than the system thrashing between 3G and non-3G data when sync'ing etc. Typically WiFi will show as 2% battery usage at the end of the cycle.
I base it off my old N1 usage, which I got from here:

Epic battery performance after months of use

Hoping to get some good feedback from those who have used the epic for a couple months or more. Now that you're probably using the device normally, as in not attached to it all the time, how is battery life? I've heard initial reports that it's not so good... Also, for those of you who have updated unofficially to Froyo, does the upgrade help with battery life? Can anyone comment how Epic's battery compares to EVO's?
Thanks.

I usually get about 9 hours in my stock battery and 6-7 on my cheap eBay ones. Overall idea say meh, its about on par with most other android devices. I'm running the stock dk28 leak as well with no battery tweaks or mangers of any sort.
Sent from my SPH-D700 using XDA App

On most of the DK28 roms I'm pulling a solid 10 hours with moderate use. For reference, If I leave the phone on standby all day in my house it's lasted 23 hours, if I recall correctly. Honestly that's pretty damn good for a smartphone.
EDIT: I don't use any battery-manager or powersaver either. Brightness = Auto, bluetooth/wifi/4g/gps = 1 is on at any given point in time usually. Google auto-sync = on as well as touiteur (twitter) and facebook notifications every 15 min.

I have been impressed by my battery life actually. I can't speak for the EVO(although maybe soon since my friend might give me his as a backup). I can usually get between 4-5 hours of play time(surfing, texting, apps, music, wireless tethering, movies, etc) The rest of the time it is usually idol. I usually charge it over night, unplug it around 7am, then plug it back in around 11pm. At 11pm, I usually have between 10- 30% battery left.
I just switched to a froyo ROM(bonsai, which is excellent) and so far the battery seems to be about the same. By lunchtime 12:30 it is usually between 70-80% and right now I am at 72% but I also had some extensive time testing the tethering feature.
To be honest, I had a blackberry, and the battery life was a little better, but the features were not nearly as good. It amazes me the battery these things get with that amazing samoled screen.
disclaimer: I do not play games outside of sudoku and spades, so my CPU does not really get challenged, which probably accounts for some battery savings. Oh and I use regular wallpapers, cause I don't really like the live wallpapers.

Im on 2.2.1,and I have to say I see a 40% increase in battery life compared to 2.1,and thats about 11-12 hours,no battery saving apps either,well except setcpu,which does help,but its set at 100mhz - 1ghz conservative.And I use it more now then when I got it,I havnt got tired of it at all.I have noticed the first 10% goes the fastest,and I have calibrated twice since moving to the ROM im on,and its the same in all,so if you get an Epic dont let that scare you.

I've had an Epic since a couple weeks after it was released and I think the battery is probably working the way they meant it to, which means a solid day. I charge it overnight, unplug it when I go to work, plug it in when I go to bed, and I'm usually at around 40% by that time with moderate use. I don't generally have problems with battery drain.
The exception to this is when using GPS with the screen on. It's really difficult to use this phone as a direct PND replacement even though it's basically made for it (especially with Froyo, which fixes the GPS lock issues), because the screen and GPS together will drain the battery from 100% to 0% in about 40 minutes. My dedicated PND, by contrast, will give me 8 *hours* of continuous use on battery power.
Also, I have a 1000mah car charger and even with that connected, the battery still drains when using GPS and the screen (it just drains slower). I have to just turn the screen off when I know I won't be needing to make a turn for a while.
The one thing I wish about the Epic is that it had a regular old LCD screen. The AMOLED screen is the one battery killer - you really need to watch how long you have it on. In normal use it isn't much of an issue, but you just can't do much of all the cool things they advertise that you can do with this phone (like GPS or watching movies).
I do also keep my screen turned way down, which makes a difference, but it's still a killer.

Well, I reported over in another thread that with Froyo, and basically having my phone sit around and do nothing with no WiFi, GPS, Bluetooth, no "fixes" such as switching to airplane mode or killing the DRM service, and no "battery saver" programs, I was able to get 108 hours on a single charge with the stock battery (1500mAH). That was with the screen on time of about 50 minutes and talk time of about 40 minutes... (pictures here)
It all boils down to how you use your phone, but in a stock configuration, the power management seems to be better on 2.2 than 2.1 as shown by the large amount of "idle" time I was able to get on a single charge.

I don't disbelieve that - in my post above, when I'm talking about draining the battery with GPS and the screen on in 40 minutes, or when I'm talking about having 40% battery left at the end of a regular day, it's almost always with a screen on time of 30-40 minutes. So 50 minutes sounds about right to drain the battery completely, with nothing else on.
I'll bet if you had 0 minutes screen on time - just let the phone sit idle - you could have probably gotten 200 hours or more.

LOL, what's the point of having a phone then? 8-9 days without using it? I dont think I could hold out that long.

No I know, I was more just clarifying so it didn't seem like we contradicted each other. I think the important stat is really screen time and then any extra radios you have turned on. Just with the regular radio and nothing else, you could get ridiculous battery life on the Epic. It's the extra radios and screen that kill it.

My phone gets me through the day. About 20% down in 7 hours on standby, so thats decent. Heavy usage with full brightness on and live wallpaper starting in the morning, stopping at like 6 A.M...it'd probably die there, for me at least.
The battery is good; I'm running the dk28 rom but it really hasn't affected my battery life at all.

On phoenix kernel i was getting 20-36 hours moderate to light usage. With acs xtreme kernel I'm getting 12-20 hrs w/ moderate use.
That's about 3-4 hrs of screen on time, 45-60 min of talk time. Emails, text ing, twitter, xda, and some various forum reading. Angry birds if waiting in line somewhere..
Note: I leave background data turned off and manually sync/refresh mail/contacts/data. I have no need/desire to be alerted evrytime someone updates twit/fb. I also use juice defender.
Sent from my SPH-D700 using XDA App

I can barely look at my phone on full brightness - it hurts my eyes with beams of awesome.
I get between 13 and 16 hours depending on how much Angry Bird time I put in that day. If I'm doing normal browsing, facebooking, etc then I'll be closer to 16, but gaming drops my battery like a rock.

Thanks for the replies! I think I'm convinced a lot of it has to do with how you use the device. Pretty much how it went with the EVO when it first came out... lots of people complaining about battery and then it kind of faded once everyone settled down. All I need is to get from early morning to right before bed.
GPS with google nav is a killer on any Android with decent screen size and resolution I think. Anyway, I thought SAMOLED is supposed to save a little battery? Or is that only if the background is black? In any case, I usually dim my screen to 30%, keep GPS off, keep auto-updates down to a manageable size, and use some other tricks to save battery, so I should be good to go.
I tried to thank all of you with the new thanks button, but didn't realize there's a limit per day haha. I'll finish it up tomorrow.

As far as I am concerned the battery life on DK28 is amazing. I use overclock widget set at 1000/200 screen on and 400/200 screen off. I can pull more than 30 hours with multiple phone calls, texting, email, web and games for over an hour. Here's the screen shot I took today before putting the phone on the charger.

I've noticed a substantial improvement in battery life since upgrading to 2.2. However, I also began using the Epic Experience ROM shortly afterwards, which boosted it even further. That, plus Juice Defender nets me a perfectly acceptable battery life.
I used my phone heavily today and still got about 18 hours out of it before plugging it in before bed at a 35% charge. On top of that, my phone's never felt snappier.

whoa, is it normal for the epic to take 3.5 hours to charge? If so, any explanation? Past devices i've had tend to take an hour less... Running 2.1, does Froyo help?

Currently on Epic Experience with SuperPower installed. I unplugged the phone about 16 hours ago and it's sitting at 36% with light voice and moderate SMS/data use.
Battery life definitely improved after upgrading from 2.1, even with light use it would be dead in under 12 hours on stock 2.1/DI17.

How to get unbelievable battery life
I have some very VERY helpful hints of great battery life for the Epic 4g. (as i am on hour 26 to 28 and have 20% left with about 1 to 1.5 hours of screen on use.)
First off, use black, or almost black background. Our screens are superAMOLED. This means that if the screen is showing black... those particular black pixels... are simply not on. If you have the home screen black, and have no icons on it, then the status bar is all that is using power... maybe 6 or 8 percent.
Next, Lose the brightness. A few helpful hints on this. 1) uncheck the autobrightness in the display settings 2) turn the brightness down in the display settings 3) If you slide your finger from right to left across the status bar at the top, the screen will dim, if you slide your finger from left to right, it will brighten(this causes accidental brightness 4) cover this light sensor on the right side at the top (I believe) because the phone seems to have a problem always autobrighting even with the uncheck in the settings. This is done best with electrical tape, or perhaps finger nail polish. These things should ensure to always be at minimum brightness
Next, Install Frankenstein Froyo Rom(lightest rom=less cpu usage/blackest rom=less screen battery usage), And Genocide Kernel(undervolted)
Next, install task killer(keeps the rom at optimum efficiency meaning less cpu usage assuming you are killing the apps 3 or 4 times a day) install set cpu(This allows you to limit the cpu clock speed(400mhz is optimal usable and battery settings)
Things to remember, ALWAYS TURN THE SCREEN OFF.
If you pick it up every thirty seconds to see if you have a text, then just sit it down... whats happening now.. The screen is staying on for another 15 seconds probably. DUH!!! bye bye battery!!
TURN OFF THE SCREEN BEFORE YOU SIT THE PHONE DOWN!!!
Turn off gps when not in use.
Turn off wifi when not in use.
Turn off 4g when not in use
Dont use it as an mp3 player.
Dont talk on speaker phone.
Those last few were pretty obvious.. but some people need to be told.
I Hope this helps anyone looking to conserve battery. Follow these steps and i promise 24 hours plus ever time and often as much as 48 hours.
Enjoy
EDIT****
By the way, When you set yourself up with this rom, you are making your phone TWICE as fast... LITERALLY. Hard to believe that a ROM could be twice as fast.
With stock android2.1 this phone gets 800 to 900 in quadrant(benchmark tool/tell how fast your phone REALLY is) Stock android 2.2 quadrant score is a little better scoring as high as 1000.
With this setup, i have gotten as high as 1950 in quadrant. No joke. This is reflected as you cant even tell the phone is clocked down to 400mhz without heavy apps and REALLY paying attention.

I used to get about 8 hrs of use before having to charge. Battery would drain even when I wasn't using the phone. Since flashing to DI18 a few months ago battery life has been great. A good 15-17 hours of moderate/high use and minimal drain with the phone on standby.
I lower the brightness all the way, end the DRM process and do the TWS trick after a reboot. No fancy battery management app that disables all your phone for the sake of battery.
I expect 2 hrs of the screen being on before my battery gets down to 20-30%. Which I think is very reasonable for moderate to high usage.

Battery drained in 12 hrs (screenshots included)

- I tried removing a lot of thumbnails to combat the mediaserver drain
- I removed a clock-app that constantly used around 4% cpu
- I tried removing facebook and google now or whatever their weather/intelligent widget is called
- I tried using greenify on everything i could think of.
Today i woke up to a phone that had a depleted its battery more or less overnight with just 30% screen on time.
I did experience the phone lasting 2½ days without a charge during my holidays and that was with 2 hrs screentime and 35% left. That's the kind of performance I'd wish for. The phone is rooted, and I'm using solo launcher, but hardly any customization that aside.
I took SCREENSHOTS of everything that might be important. Maybe you can tell me whats wrong. Under cpu states it says 1khz and only that. Isn't that a bit odd?

IMO that's not too bad I have a 7200 mah battery and it last me about that longs with around 4 hours of SOT, but it seems like your phone might be clocking too high, and brightness might be too high for the screen to be the main suspect like that, with only 30 mins of SOT

I think it's linked to the 3g/4g. If I disable that my phone will last significantly longer. I spend roughly 2 hours on transport a day. Conversely during my holidays it stayed in and around a summerhouse for 2½ days on one charge with 3g with long screen time and camera use. That's a hypothesis at least. Also I didn't use google music or any other audio player at that time.
I can get 2 hrs of SoT, but then I have to actively spend all the battery in the first half of the day, because after a full day the battery will be more or less drained regardless of SoT

If you don't ever use your printing features then i would delete those apps also because the printing service are usually turned on by default and searching for something to connect too or make sure its turned off in your ROMs settings so its not constantly searching.

90% of the time that unexplained battery drain occurs it is caused by low signal and the phone constantly trying to lock on or find a better signal. You can try to decrease this drain by using wifi in low signal areas but your phone will still drain your battery if the voice signal is low to. My phone lasts all day and then some when I'm in good signal coverage. When I go to my brother in law's house which is out in the middle of no where my phone will drain the battery in a matter of hours.

Battery Life?

What are you guys seeing as "normal" sot? I know there are many variables but I also find that at the 2.5 hours the phone has been off the charger, I'm already at 75% with only 1 hour of sot. I am stock with power saver turned on even and no rogue apps listed in Gsam Battery Monitor. Bought the phone on Friday..... Call me confused.

I'm getting about 4 to 4 and a half hours SOT. Seems like the display on the HTC 10 is a major power hog.
In terms of optimization they did a fantastic job as my radio is only listed as using 3% of my total battery and app usage is only 21% according to GSAM, meanwhile Screen has used 72% of my battery, and I tend to run the display at a pretty low brightness (about 20-25% brightness) I have 22% battery remaining and screen on time so far of 3:38

Running full brightness all day without power saver, my record so far is 4.5 hours, generally though I only need about 3 hours or so out of it per day, and 3 or 3.5 hours is my average.
How's your signal strength?

I guess I am around a similar time frame then. I hit 5 hours yesterday but like you, the screen is pretty low and it still eats up the battery pretty good. I guess Ill have to "optimize" a little better.

Signal strength is not great. I do bounce around band 25,26, and 41 quite often but my signal strength meter under the battery settings is a mess of a rainbow. Here's to an update heading our way soon...

Battery Life on Pixel 2XL

Has anyone been getting battery life like this on the Pixel 2XL? After an hour or so of screen on time I'll already be at 80%. I think I noticed it in December. I've been getting 3.5 or 4 hours of screen on time whereas I used to get 6 or 7.

I would say, losing 10% battery for 30min screen on time is quite normal. At this rate you would get 5hrs of SOT.
Judging battery life based on SOT only is quite wrong too. What you were doing on that screen matters. Gaming will be very different from netflix. It also depends on your network signal strength, whether you were on wifi or mobile data, what other background stuffs were running....

You could run accubattery for a week or so and see if your battery is degrading. It also does a pretty good job tracking what apps are using the most battery

Do you use it at maximum brightness?
My first 10% constantly give me about 50-55 minutes

Have you changed usage habits in any way? (more gaming or anything else that maxes out CPU)
Are you in a cell network fringe area and barely get signal? If your phone is struggling to maintain signal, that will drain battery fast.
Do you have a lot of apps using battery/data in the background?
Have you tried a factory reset?
I have not noticed any degradation in battery life since December. I still get at least 6 hours SOT between recharges. When I am using the phone, it typically loses ~10% per hour. When phone is asleep, it drains less than 1% per hour.

I notice me too a drop of battery life since December Patch.
10% give me 1h10 min of video (in wifi) Now it's more 40min, 50min.
And data suck my battery like nothing, it's like snow under sun.

I have not noticed any degradation in battery life since December. I still get at least 6 hours SOT between recharges. When I am using the phone, it typically loses ~10% per hour. When phone is asleep, it drains less than 1% per hour.

I don't use my phone for gaming at all. I do live in an area now where I don't get great service, but I'm on wifi like 90% of the time. I do keep apps open all the time. I haven't changed how I use this phone at all. I used to get almost 9 hours of screen on time with many apps still open in the background, but I now I don't. I'm starting to think I need a new battery.

10% give me 1h10 min of video (in wifi) Now it's more 40min, 50min.
And data suck my battery like nothing, it's like snow under sun.

I think it's my battery. A couple of months of ago my phone would cut off when I tried taking a picture with Snapchat when my battery was below 30% or so. I looked it up and it's sort of common. Someone said a battery replacement was needed.

Same here. Never had a huge drop in percentage after a restart like you described.
