[SOLVED][Q] Battery issues?

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

Battery Life Bug - Heads Up

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...

Had you installed anything that could have caused this?

Mine was plugged in all night and said 100% then froze this am and dropped to 10% after reboot

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.
Transmission sent from a Galaxy S II.

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.

100% to nearly dead in 5.5 hours with no usage at all

So my battery life so far has been hugely inconsistent. The first day it was draining so fast (60% in an hour) that I contemplated turning around and taking it right back to the Verizon store.
I decided to give it a better chance than that and gave it a full conditioning cycle and all seemed well - I got 16 hours with moderate usage including an hour and a half where my screen was constantly on! I was very pleased. Extremely pleased.
So I charge my phone back up to 100% before I go to sleep then take it off the charger once it does. I drift off into dreamland, dead to the world, and five hours later I decided to check my phone for calls, texts and email.
Before I could even pull my notification bar down I saw something horrific - an extremely low battery capacity, nearly red. Checked battery usage and it said it went from 100% to 13% in about 5.5 hours.
Android OS - 64%
Phone Idle - 10%
This is the big indicator. Under Android OS, my phone (not the display) was kept awake for an hour and a half overnight. I'm really not sure what's going on here and what's causing this to happen. I haven't downloaded much - 1 game, Skype, Google Reader, Facebook, Tweetcaster, Evernote and Foursquare - and none of them showed any signs of being the culprit.
As you can tell, this is very worrisome. If I can't get more than 5.5 hours on a full charge what use is this phone to me? Does anyone know what could be going on or has anyone else run into this issue?

Horrible Battery! I just dont understand!

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.

[Q] Do I have a faulty device.?

So I had several calls yesterday for over 30 mins each..
Each time i would hear echoy sound of my voice, and i also feel like i could hear the voice coming out of the phone lol, even though the phone isnt on speaker.
I also my have a bad battery it'll go pretty low i guess. Yesterday was my first full day using it, went to work at 70% since i forgot to charge it, at noon unplugged it's at 100% came home around 9 and got 10% left. , so i got 9 hours in total, from calls. light browsing, light twitter, facebook use.. I havent even setup my work email, and i constantly get over 100+ emails a day on my account. So i know battery will go significantly
Should I wipe everything clean and see if it works.. I have 14 days to return for a new one.
also today left my house at 7:30.. it 9:50 now and already at 75%...

I think someone else on here had similar issue with having an echo when speaking into the phone. If im not mistaken they exchanged it and the new one did not have the problem. Maybe you should take it in for an exchange.
As far as battery life, well it seems to be varying from user to user. I am getting pretty good battery life, anywhere from 12-15 hours on a charge with medium use. On light use I get well over 15 hours. There are some that seem to be having poor battery life. Have you checked your battery stats? Whats your android OS % at? And what is your screen on time? Have you turned on ECO mode?

Assuming you dont have a lemon, it all depends on how you use your phone.
Do you have lots of apps with push notifications?
Or do you have lots of apps that check for new notifications every 10 minutes?
Screen brightness? Screen-on time?
What radios do you have on?
...the list goes on
On a typical day, I can get about 12 hours with moderate use (3 hrs screen on time). Close to 24 hours with light use. Mine idles pretty well (approx 1% or less battery loss per hour).
FWIW - my 'Android OS' is usually at around 50% and screen is at about 25%

Doesn't seem like a lemon to me. Falls somewhat in line with my battery experience.
You can check screen on time by going to the power saver in settings, scroll down to battery use and hit that. Then hit 'screen'

Yeah - I never turned those on or used any kind of juice defender either (thought I am on Wifi alot). I think you're fine.
Try this - fully charge your phone before you go to bed. Leave it off the charger over night. See how much your battery drops. Even with a few google accounts on push, facebook messenger push, instagram push, LG social+ and a couple of news readers that auto-update every few hours, I've seen my battery drop at most 5% over 7 hours.
