Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use
none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.
Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?
tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps
well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up
I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.
I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

Are you on stock? You are not using quick boot are you? That is a known bug in that app.
I am on SRF 1.1.1 and when I switched over I did the battery calibration where you charge while on (always to 100%), unplug, charge while off, unplug, charge while on, unplug and then wipe battery stats. I then downloaded and ran the battery calibration tool, ran my battery out and charged to full. It's a monster now. I can really say I'm one of those people who wandered around for an hour randomly doing things and checking my phone as usual and where I would have normally been at 94%, which is fine life after an hour, it just turned to 99% at the 1 hour point. I will keep watching to see if performance is better at first and wanes or what.

Where did you get this battery calibration tool? The market?
I think his issue is the big percentage changes upon reboot which is a bug and not an actual percentage drop. It was especially noted with Quick Boot.

Sure, but if he stops using reboot and calibrates his battery settings, won't that fix things?
Edit: poor terminology

Yes. But he hasn't come back to confirm or deny this is what he is doing. Not even sure if he is rooted or not. Thanks on the Nema tip. Gonna download it now.
Yeah that app is awesome. I use it all the time.

Im havng the same exact problem, i power down and back on and the percentage drops drasticly. Im on SRF 1.1.0.
Follow my post exactly. I don't know which battery calibration kicked the weirdness, but it's totally stable now.

The hardest part is finding what will tun out the battery fastest. I suggest flashlight screen on bright blue with pandora, tunein, and mlb running a live game.

Don't count a reboot and a major change in percentage as horrible battery life. I have been getting that recently because I beta test and when it drops like 40% on a reboot I power down, plug it into a charger, it goes back to where it should be, then I power back on and it is back at the level before the reboot. It is a bug somewhere. As for your normal usage, how many hours do you get on a full charge without any reboots? Users report anywhere from 10 hours to 18 hours with some usage (of course there are a few extraordinary cases out there).

..that's continuously playing music with my screen off...n sometimes playing a gameloft game or PES 2011 for 15 mins and checking engadget every 20 mins or so( no Widgets btw)...when I play music for an hour with the screen off, I get atleast a 6% drain....it used to to be 3% drain or less the first time I got the phone (a week and half ago)...I am just trying to get the best life out of my battery

Are you streaming music or playing mp3s stored on the phone? If you are streaming and the 3G or 4G keeps dropping out it will kill your battery constantly reconnecting.
I cant tell if it's always been like this. Or if this actually isn't normal because I'm always concern with battery life. Im a very heavy user in the sense my phone will be on and im texting, xda, social apps i.e google +, email check every hr, and twitter.
However, i started feeling like my battery has been draining alot faster when the screen is on. I have no problem with the phone sleeping. I was experience this on Calk rom and now acs ics rom. I literally can look at my battery percentage drop 10% in like a half hour. Is this normal if screen is on the whole time? I've used better battery stats and system panel I can't find anything causing the drain. I see the suspend and events but doesn't that effect the phone sleeping?

Are you on the new modem? Looks like you have weak a signal. EG31 might help a little if your not on it already. I used the full EG31 tar right when it dropped and have been getting great battery life (it may be to early but so far so good)

turn your display down to under 50% you won't see a difference except outside in daylight and kill this app every time you reboot the phone hit Settings>Applications>Running services then hit DRM content > stop > ok
I get over a day on one charge.

Ok ill try the drm content stop..however my display brightness is already down at like 10%.
Also, kill the Social Hub as well, that drains the battery significantly.
You might try one of several roms available in dev. They address most of the aforementioned issues.

The biggest battery drain reason is the location by wireless network option. Make sure its unchecked. Ever since I did that, my battery life has been awesome. I get to keep my brightness high, Bluetooth on, etc...

All the basics (brightness and all that stuff) on top of the stuff you have running. The darn task killer/manager I see in the icon top left of your screenshot is a HOG on resources check the caching... You can literally **** with these phones for half a day to set it up the right way to conserve. I think wireless is hogging too but I am talking primarily about the first part of your rapid loss, the left part of the graph so to speak.

I purchased an extended battery and was still getting crappy battery life. SpareParts always FC'd on me... but last night I found Badass Battery Monitor in the market and in my opinion it's even better than SpareParts!
It helped me find that the Hotmail app was keeping my phone awake for almost an hour every day even though I had it set to download email only once a day. Removed that right away.
Plus it gives a great % readout in notification of the battery level. I think it's a fairly new app, but it really is worth checking out especially if you're having battery drain problems.
Just killing Social Hub has increased my battery life significantly. I'm at 11 hours now on battery, with 62% left. This is from last night when I unplugged the phone at 100%.

I'm on the Sydnicate Rom there isn't even no social hubb app. He has alot of the mods like noCiq and everything. My phone sleeps well its just when I start using it I can see it basically draining like 10% every half hour. I'm a heavy user I know my phone will drain fast while I'm on it I just would expect it to last 8-10 hours on heavy use.
Right NOW:
I'm at 4 hours 12 mins 22 secs at 37% left.
Display Time is 50% 2 hrs 41 mins 51s (Brightness is set all the way down)
Android OS 10%
So I'm assuming in 2 more hours my phone will die. If this is just normal for a heavy user then I guess I have to deal with it?
I was very disappointed with my Epic Touch when I first got it. I was getting a dead battery in about 6 to 8 hours no matter what I did or did not do.
Calibrating the battery seems to have fixed it.
I'm at 73% battery with 8:32 hours up time and I've made about 12 calls ranging from 2 to 10 minutes.
I've also checked voice mails, emails and other stuff.
I just charged the battery til it was full, plugged and repeated until it stayed at 10%, popped into CWM5 and cleared the battery data and then used Battery Calibration from the market (free) and it's like a got a battery upgrade!
As far as wake lock issues, I've not having any of those. I took my charger off the phone around 3:30am this morning (100% charge) and when I left for work at 6:50am, I had 98% battery still.
When I got to work it was down to 96%, I checked my email on the drive there.
I'm trying this out, wish me luck.
There doesn't seem to be any possible way to charge my battery to 100%, unplug it and not have it immediately drop to 99%.

If those screens are both from the same charge, I see nothing wrong with your phone.
you have 17% left, and you have 2.5 hours of screen on time. So you're on target to get just over 3 hours of on screeen time which is completely in the norm for these phones. AND you're over 12 hours. I don't understand what else you could ask for?
People get all caught up on total charge time, but, to be honest, it's completely IRRELEVENT.
If I dont use my phone I'll get easily over 48 hours out of the phone... Screen on time is what matters. And from a full charge, if I were to use my phone for 4 straight hours without stopping, it would be about dead. When the screen is on, you're using the phone, and the display is the biggest battery suck out there. When I do all the tricks to conserve battery, and I set it up right, I get 4 hours screen on time, which is pretty incredible with these phones.
Now, If you WANT to get better then you have right now, a few things are coming into play.
1) Your signal is weak, this will suck power no matter what more then it should, so get better signal if you want some more time out of your phone.
2) If you installed a new rom, and you didn't calibrate your battery properly, you're losing battery life.
to calibrate properly:
a) download battery callibration app from market
b) charge to 100%
c) unplug battery charger and REPLUG IN and wait for 100%
d) repeat step c a couple times
e) while plugged in hit the calibrate battery button in the app
f) unplug phone and use til dead and recharge
This will yeild you the best battery life.
3) De-Theme. Although I use a theme, every theme I've tested, for one reason or another, drains my battery faster then running the stock phone theme.
4) If you haven't done the basic battery saving things, you should do them to help yourself out. Here's a few I use.
a) Turn off background data, you only need it on to use market
b) Turn off, or set sync for all email and social apps at as long intervals as possible
c) dont use any widgets
d) download watchdog lite so you can see when apps are acting up and using extra battery
e) when you're done using your phone, open task manager, kill all apps, and clear memory
f) always leave the brightness off automatic and as low as possible
g) download SETCPU and run your phone at 800mhz, and undervolt as much as possible (50mv most all phone can take)
h) use black or dark wallpapers, on LED screens back means the pixel is off which uses less battery
G will be your biggest battery save. I've also tried using the SUPERFREEZE thing in the dev section and, besides in sleep mode, I saw no adverse effect. If you wanna kill socialhub, fine, but I dont see any noticable difference on my phone with it off.
If you do all these I promise you'll get better battery life.
Wow, I did a proper calibration today and I'm getting great results already. I've calibrated before but I never had cleared stats in CWM or did the unplug then replug charging thing.
Anyways, I after 12 hours I'm still at 35%! The longest I've ever gone before is 12.5 hours. Screen on time = 1 hour 30 min, but some of that was a battery intensive game (puzzle quest 2). Also i'm running calk's rom, so i'm sure that helped.
Thanks kdoggy, i didn't expect to see results this great.
Those are good tips too Jermzz, thanks!
I was at about 49% battery life when I rebooted my phone (to try my new Maxroam sim card) and when I started my phone again I was down to 22%?!
I have attached a screenshot to show this? Anyone have any ideas what the problem is? Is this normal. My ROM & Kernel is in my Signature.
I've had the opposite happen, too. Had 40% battery left, rebooted, suddenly it had 60%.
I'm 99% sure it's not an actual change in battery charge. It's probably something related to how it measures battery capacity, and rebooting throws it off. I wouldn't worry too much about it.
This has happened on my Captivate as well as my GNex when it randomly reboots. I have noticed that it usually corrects itself over maybe a 15-20 minute time period. I have no battery charts to prove, but when my captivate would crash and reboot the battery would be much lower than it was before like you described. If you watch, you'll see the percentage go back up without charging. Its just a glitch in the reading when things crash or don't shutdown correctly.

Hello everyone,
I observed a strange behavior of my arc s , when the phone reaches 100% charge and later when i unplug it my phone spends almost 20 minutes at this point and after some time it starts to discharge ie. it comes down by 1%.
But if i use it hear after it discharges rapidly.
I find this behavior very odd !
Can anyone explain me this behavior ???
Thank you in advance.

Check battery use
Check battery use to see what is consuming the battery
Maybe WIFI and sleep policy,Bluetooth,Network type WCDMA/GSM ,GPS and accounts sync ?
Observe the diagram or the slope in the battery use to see is your battery draining fast or is it normal,also what rom and kernel are you using
Isn't that the normal behaviour of a battery coming from a smartphone? .-. Mine's like.. 20 minutes on 100% before starting going down, and it doesn't affect my overall battery life at all..

I have observed all of that.
Everything is fine, as the display uses the battery predominantly.
My guess is that is a sign for use to change the battery.
And also i see spikes in chart instead of going down the charge goes up and down.
Sent from my LT18i using xda app-developers app
how old is the battery?
how old is the battery ?if the spike goes up that means it is connected to USB and the phone is charging .attached is my battery usage 7 % in 11 hours the slope is continuously going down as it's been unplugged and running on battery only ,phone and battery are a year and half old
The "spikes" you refer to are because your battery isnt well calibrated...
You can charge it fully, use it and when its around 5% charge it again to full. And if you delete the battery stats your battery must sette down over some day or two.
But for a better response you need to upload a picture of your battery stats.
My battery sometimes stays in 100% some minutes, some other times is goes down to 99 very quicky, but its normal for me cause it usually lengths for two days + with normal use

Yes i totally agree the oly time the graph should go up is when its plugged in and not wen unplugged.
But i sometimes see the spikes when unplugged.
Nevertheless it has not degraded the performance.
