So this has happened twice recently. I'm not sure if it's the battery or an app that caused this.
Basically I left my tablet at around 40% overnight idling and throughout the day at home while I was at work. I come back around 8 pm and pick it up..battery is dead. Like completely dead, the tablet won't turn on until I charge it a bit. It's kind of ridiculous in an approximately 14-16 hour period my tablet died going from 40% to 0 on idle?
How can I find out what's causing this? I'm not really sure what changed because I haven't really installed anymore apps in the past few weeks.
@C2Q Go into Settings > Battery > and then take a screen print and post it here of what % of battery each app has used.
Should give you an idea from there. If I were guess I'd say it will be Android.System thats draining it...well thats what happened to me.
Thanks. Yeah I have tried that, I also have a bunch of other battery monitoring apps. All it says is Android OS but no specifics. I'm wondering if there's a way to tell after rebooting, what caused that much battery drain (app wise)?
@C2Q Take a screenprint and post it here..
Hmm..I'll try to get one screenshot when this happens again. Yesterday I charged to 100% overnight, unplugged in the morning before work and then came back after work about 10-11h later to see it at 99%. That was pretty normal. Wakelock detector only showed Gmail as the biggest battery usage in those 11 hours. Will keep an eye out to see if this mysteriously drains again.
What rom are you using ? It could be a faulty kernel if android os is running like crazy.

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

Initially, I was very surprised and pleased by the battery life of this phone. I charged it on Saturday, and my usage since then took it down to about 73% this morning. 32 hours of use and 27% battery drain? I'll take that!
But something weird happened today. About midway through the day, the battery just started to crater. Worse yet, charging didn't do anything! The charging indicator animated, but battery life was still falling precipitously. I used it constantly on the train this morning, so I get why it was at 58% by the time I got to work, but then from 8am to about 2pm, it went down to 30%. Then from 2pm to 3pm while it was "charging", it went down to 18%.
Of course I googled the hell out of this, and came across this thread
And rebooting the phone magically stopped the battery drain, and allowed it to start charging again. So I guess our SGSII's are just like the international ones in that regard. Apparently some ROMs have fixed this, but we're still a little new to benefit from that approach. So, just a heads up: if your battery chart just starts falling into the floor, reboot and all will be well.
Note: this also explains the "Android OS" entry showing up at the top of your battery charts. I was shocked when 2 hours of display only accounted for 22% of my battery usage, while Android OS was 68%. Apparently the suspend mode goes insane sometimes and the process of attempting and failing to sleep the phone sucks the battery dry. I'd say that's pretty ironic, myself.
This happened to me also. I was not even touching my phone while working today and it beeped saying 50% I'm like wtf? So I let it sit still working and it beeped saying it needs to be charged. Crazy but I sure do hope this helps and is fixed soon.

happened 2 me couple times, i thought some app was keeping my phone from going to sleep. so i tried spare parts, spare parts doesnt work on stock gingerbread roms on samsung... so i cudnt figure out wat was going wrong... because lets say my battery was at 80%, after i reboot, it would be at 55%, just with a reboot...
i figured something was going wrong in the background, and the battery stats are not reported correctly, your REAL battery percentage shows right when you reboot...
-------------------
after i rooted the phone, THIS FREAKING EXACT PROBLEM made me do a factory reset on my phone, which put my phone in a boot loop... after waiting 16+ hours for a stock kernal to come out, i had to brick my device on purpose (so sprint could not even turn it on), and dey gave me a new SGSII... if i didn't brick it, they would have known it was rooted, due to the international splash screen...

No. I haven't installed anything since yesterday, when it was (supposedly) sipping the battery. It just started going nuts this afternoon. That's why I started looking and found that bug thread for the international SGSII. Apparently there was also a bug in 2.3.3 that would cause some widgets to suck the battery dry within hours, while idle and even in airplane mode. So I guess they're moving in the right direction.
I had a weird issue just now. Battery was at 26 percent. Did a reboot by holding the power button down for 8 seconds or whatever it is. When it booted back up about 30 seconds later i had 10 percent battery.

Today is my first day giving this phone a while, and I've been awestruck by the battery life.
Screen on for a large chunk of the past 12 hours that I've owned it, and I'm still showing about 50 percent. I imagine a battery anticipating 4G usage but me having it turned off all the time gives the phone a real edge, lifewise.
Not looking forward to it cratering like you guys have seen.
HOW CAN YOU GET THIS LIFE AND I CANT?????
I hard reset and started over for everything
Should I take it to sprint store?
like it was some what pointed out alot may be due to the charger....i kept my epic 4g charger and have been using that

I kept my htc evo one, after hearing about screen sensitivity issues and now this.
I got 23 hours with some heavy use on the first charge. It should only get better with the new kernels.

so this is 4 out of 4 samsung devices that do this. both galaxy tablets - 7 and 10.1, droid charge and now this. none of my other android tablets or phones do this. the battery just drops with nothing being used. at -2ma usage it goes from 60% to 20% in seconds or from a reboot.

That may be the case, but I know from my Droid Eris, that bugs just happen. It had the infamous "Time without a signal" bug that used like half the battery life per charge. It basically had to be ROMed to work right. And that bug was there for over a year.
It's just sad the phone makers are being so sloppy. It makes Android seem like a POS, when it's really their fault.

Is it normal to lose 27% charge with jjust 40 minutes of screen on time? Phone has been off the charger for maybe 2 hours. Im not getting anywhere near the claims of some people...

Thanks guys for this thread, My first day I went out and had the phone and installed everything and got root and did titanium backup from my EVO 3D, and played some third blade, and got great battery life, but then yesturday went to work and it just tanked 5 hours and down 50% i was shocked, going to pull the battery if that happens to correct that.
This really disappoints me to see the 'Android OS' bug hasn't been fixed by Samsung despite the issue being reported this Spring when the international SGS2 launched. If I remember correctly it's due to the phone not going into 'deep sleep' after it's been unplugged from the charger. Android OS will be listed in the battery stats as the top consumer of battery.. the workaround is to reboot the phone after pulling it off of the charger in the morning.
I hope Samsung stays true to its word and provides steady firmware updates for their recent devices.. NOT to introduce new features but to fix some of these glaring issues (this one first and foremost)

I'll have to try that. I know rebooting after the system goes nuts stops the drain, but I didn't realize it wasn't sleeping after being charged. I'll report back.
I experience weird battery draining periods throughout the day as well. I think I'll just try to clear my battery stats later.
Hi all,
I've had for the past couple of months some pretty dire battery life on my phone and I'm unsure as to what exactly it is thats causing it.
A couple of months ago I was on the Modaco custom ROM, i think it was version ir8, and I was able to use my phone lightly during the day from 7am every now and then, and by the end of the day say around 10pm id still have at least 60% left. At the time the longest i went without a charge was about 2 days and maybe 4-6 hours. I can't remember exactly.
Anyway, I updated the rom a couple of times, and things have never been the same. I tried reverting to the older version but things were still bad. I also tried a different rom (AOKP) which im still on now, but still things are not right.
Right now after ~14 hours on battery I have 45% left, and this is actually a good day...usually with similar use id be lucky to have 20% remaining by now. I'm unable to post images it seems. I wanted to post an image showing 63% battery, 9 hours 49 mins. Android OS > 28%, screen > 26%, phone idle > 17%, mobile stand by > 12 %, maps > 5%, wifi > 3%
Up until I noticed my battery life going down the drain I never noticed the android os using up much battery, but maybe I just wasn't looking for anything. It doesnt seem right to me however....
What steps can I take to properly figure out where the problem lies?
For reference I'm on the AOKP ROM build 40, and franco kernel milestone 4 on GSM Galaxy Nexus. Any other info needed?
Calibrate the battery. Charge full. Pull charger. Turn off. Plug back in. Charge full. Pull battery about 30 seconds. Pop back in. Turn on. And see what happens.
butter and jelly please...
You could try something like CPUSpy from the market and see what is keeping your system awake and active. Or Watchdog
Edit: I actually stopped using Watchdog because it ate more battery than what it s service was worth.
I tried calibrating as mentioned which didn't seem to do anything.
Tried CPU spy and nothing seemed odd. Most of the time was spent in the lowest frequency or in deep sleep.
I've just installed the MCR jelly bean ROM last night. And I've instantly noticed massively improved battery life, however I haven't fully restored all my apps and data yet, so I'm slightly dubious as to whether this will remain.
If once I restore all the apps and data I get battery issues again, is there anything else I could do to try and find out the route cause?
Would a log cat help?
Thanks
search the forum for betterbatterystats, if this is an app issue, then bbs will find out which app is behaving weird
The first month this phone was great on battery... Its horrible now 3 months later! I shut off all the samsung stuff that suck up the battery. I have the screen power down to the lowest setting. Sometimes when i charge the phone is says its fully charged and when i unplug it its about 98%. Does this once and awhile. I've been playing a games for about 1.5 hours. The batter is about 40%. Is this normal?
10 minutes later i just checked the phone and now its down to 30%... wtf is going on with this battery?

1.) You should get Better Battery Stats from the Play Store so you can see what could be causing this battery drain.
2.) When you unplug your device and it shows 98% it's a good thing. It means that your fuel gauge is working correctly. We have a safety feature that helps the battery to never get over charged. It helps the battery last a lot longer. The way these batteries work is if it's constantly overcharged over an certain amount of time it would deplete the battery life.

you have something in the background going on. could be a rouge app. check Better Battery Stats.
A coworker of mine has a Galaxy III on ATT same as I do. She complained about her battery to me. We both opened our Elvision Battery Widget and saw that screen times and time on battery were within 30 minutes of each other (1hr 50m mine vs 2hr 15m hers). She had 73% and I had 95%; her widget said 38XXmv, mine said 4100 (I have more stuff on than her). I had her restart her phone just for the hell of it, then I flipped through her settings and TURNED OFF battery saver. The problem went away. I've never used the battery saver and my battery stays golden all day. That said there's no telling if the restart did more for the phone than turning off the battery saver. I told her to turn on battery saver for 2 hours this weekend and see what it does. Will keep everyone posted.

Are you on stock?
Stock ICS on my S3
I'm rooted on stock ICS...
Google Now is a huge battery drain from my experience.
I'm rooted stock. No battery issues in fact gs3 has some of the best battery life I've seen second only to my hoxl.
Download autostart fromvthe market.
Find out what's running at os startup.
Disable. Things like googleplay, Googlemaps etc. Don't need to start up.
In fact the only thing required is integral Os components. At start up, I have alimost everything Google disabled.
None of your maps need time start when boot. None of them. Keep in mind I'm talkin aps like ....anything AT&T... w/e you dl'd from market.
Also go through and disable bloatware.
This will help. check your battery. It should be flat or slightly concaved. If it's bulging even slightly get a new one.
Report back and let us know.

My battery life suddenly became horrible this morning. Normally I unplug my phone every morning around 6AM, and i dont need to charge it again until closer to 9PM.
This morning, I realized that despite being on a full charge at 6AM as usual, my battery was completely depleted by 10. I checked the battery "app" and it said that phone idle and cell standby were both at 13% usage, and that was the most i had used my phone. it registered the full time (4 hours) of usage for those 2 but it also said that it was only responsible for 13 % of my battery drain each. After that there was google play services.
I figured it was just a fluke, so I reboot the phone and recharged it. Once again, the battery drained in a mere 4 hours. This time it told me a voice call of only 10 minutes length was responsible for 35% of my battery drain, and that having my screen on for a seperate 10 minutes was responsible for 25% of my battery drain. This might be fine and dandy if the actual draining chart showed a steep fall off when i made the call, but that is not the case. the chart is a straight line showing constant drainage with no steep or flat areas. I'm thinking something is definitely wrong and the phone is causing itself to drain. maybe something hardware oriented, since i dont even have very many apps downloaded.
I've literally only interacted with my phone maybe 3 times today, and I didnt even do anything major.
Do you guys have any ideas as to what is going on with it?
I'm CM10, latest stable. not the monthlies. no cpu hacks or anything, and as I said, this problem cropped up this morning. before this everything has been fine.
Please search for Better Battery Stats here on XDA. That thread has quiet a few tips on saving battery drain.

If I hadnt already made sure I was following the tips and I wasnt dead sure that something was the problem, I would not have made this post.
I did manage to figure out the problem by sheer dumb luck and a little bit of educated guessing.
I uninstalled the MyFitnessPal and tried again today. I'm exhibiting normal battery drain now (10 hours and im at 46% with not too much usage of the phone).
If you read the post I made, no apps were showing up as a large battery drainer, and all my stats were reporting incorrect times (13% battery usage for a 4 hour period despite showing me i only used the phone for 10 minutes). So something was definitely wrong. Uninstalling the app fixed the issue though, so for anyone who exhibits this problem, uninstall whatever apps you most recently installed and do a reboot.
I didnt have to reset or anything.
