I have seen others that reports around 30% and mine is usually around 60-70 for just the Android system. At first I thought maybe I added something but its like that after I did a hard reset and everything stock.
Anyone else? My battery just seems to drain fast and I need to figure this out. 60% for Android seems high what is everyone elses?
Its at 54% right now.
Android is around 43% for me.
mine stays above 40... i will say that i do believe this is a bug... with my hero android system would never get above 20%
Well at least I am not the only one..This seems really high and needs addressed.

Exactly. What gives?! Mine the highest I've seen is 31%.
I have maybe 10 apps but it was that high even after a hard reset..it can't be the phone so an exchange wouldn't help..
I just reported and its still that high..I don't get how everyone else's is so low....ughhhhh

It is too high bro. Do you have Wifi and Bluetooth and GPS on?
I have all that turned off..for those of you with low numbers are you rooted with the custom stock Rom? Mine is completely stock and I haven't even done the ota yet cause some said they noticed the battery performance worse.
I'm not sure what to do since I already hard reset and don't use live wallpapers.

I dont use live wallpapers, I have unrevoked root, and not updated to the OTA. Do you have Advance Task Manager, it works wonders for me, and its only .99cents.
Mine is at 9%...
8h 9m 2s since unplugged
Call standby 41%
Phone idle 38%
Android System 9%
Maps 9%
Display 3%
Unplugged it at around 1:40am and left it on for the alarm to wake me up at 7:30 and its now 9:40.
Only have about 7 apps installed and this was sitting idle for about 7 hours since last night.

I took my phone for a ride yesterday to make it a full testing day for the battery. I unplugged it at 9. And used it until 10:30 am, until it gave out. I did all sorts of things with it. Played 3D Games, Watched Iron Man, Listened to music, talked on the phone highly and even did some tethering. And the phone lasted more than 12 hours. I mean. COME ON! What more can you ask for!? Hell yeaH!!
I cant believe how far mine is..I dont use a task manager cause everyone says not to cause Android handles memory so great..It doesnt look like it to me!
I unplugged my phone at 6am and im at 23% four hours later..I guess ill try that task manager..I dunno what else to do!

Look it up in the market my friend. Its called Advance Task Manager. Also, try having the refresh on things like Facebook, Twitter and Mail to a bigger elapsed time. If you can do it manually even better for the phone.
Excuse me if I'm wrong, but doesn't the Battery Use screen show only what's using the percent of the battery out of 100% for however long it's been unplugged?
So, in essence, if you unplugged it an hour ago, and haven't done anything except turn on the screen, and let it sit idle and standby, then it would show a higher percentage used by Android because the 100% is divided among the only things that have run since it was unplugged.
Right now, mine is as follows:
Android System 27%
Cell Standby 23%
Bluetooth 23%
Phone Idle 18%
Display 9%
Total: 100% of the 23% total battery charge that I have USED today. Battery charge is currently at 77%)

The two screenshots below say it all. I didn't really tax my phone that much.
Facebook is set to update every hour (while pushing messages to me too)
Twitter is set to update every 15 minutes
Sync was on full blast
Had only two long voice calls throughout the day (1h:30min)
Screen brightness set to lowest all day
Q: Why did my battery go UP when it wasn't on a charger all day until now?
Q: Why did my battery get used LESS when it was awake more later on the day?
Q: Is this chart no longer reliable?
PS: I tried an experiment in which I turned sync and background data off at night and I checked this chart in the morning. My "Awake" state would flux at night. What's going on that's keeping my phone awake besides cell standby?

No problem at all. I'm actually wondering that myself. I seem to get them at a random interval (haven't been tracking) but it's definitely more often than one hour at a time. I don't see any setting to adjust when the app checks for new notifications. It's all very strange.

Battery woes ;( ... tracking down faulty Apps
Here are my first two days of use. I had auto-brightness on, and I kept on wifi when I was in range. I got pretty solid life (better than my EVO on CM6.1.1). You can see I used it fairly frequently throughout both days:
I don't have the stats to back it up but I have seen a considerable increase in battery life over my N1.
By the way, is the second battery stats screen new to Gingerbread? I don't remember it in Froyo, and I like it.

Yeah, mine only goes up to 97% usually. You can "top it off" by unplugging when it gets to 100%, re-plugging, and repeating a few times.
This may be very hard to believe, but I got 34 hours on one complete charge. I always have the brightness on full blast too. Of course, that was on very few phone calls, but lots of downloading and text messaging though. The best I ever got on the Nexus One was 26 hours.

Help, google voice update sucked my battery dry.
I just installed a google voice update on my NS. After I installed it I notice a big drop in my battery, and soon there after my battery was dead. Any ideas why?? I have since removed the update, and everything seems back to normal.
I flashed my vibrant to bionix 1.3.1 a while back, pretty much a week after is was released. Its been great up to about 2-3 days ago. I had a full charge at work at today around 2 pm, I got home and checked the battery life at around 6 pm it was at 72%. I sent out about 4 texts lastnight. Got up this morning is was at 44%. I used to get about 2-3 days out of light use. It will probably be dead by 2 pm again today.
What gives?
Network data off -
Black background -
Brightness is the lowest -
Idk maybe randomly reading it wrong? P.s. Why dont people charge their phones at night?!?!? Thats what I do
Oh i do as well usually. But like i said, the battery is starting to drop so fast that by lunch that day it was already at like 49%. By 2 pm is was full and so on. I just dont understand why its dropping so fast thats all.
Might have something to do with the battery
Check what's running in the background. The other night I was just using the phone normally and put it to sleep, checked it a few times and it was dropping 1% every 15 minutes or so. Noticed it kept checking into something. VVM and Market Checkin was running, killed it and it seemed to help. Also discovered (might not be true) that the New MAPS and GMAIL apps constantly check in and drain the battery after removing the updates phone seems to last longer/as it did before..:/
oo maybe that might be it. I Just updated a boat load of my apps a few days ago. P.s. how do you remove just the update?

also clean up Your battery stats in clockwork and recharge it with wall outlet Your battery might be recalibrated and when it shows 2% left u might have 10 really instead that's why clean battery stats and recharge.
or sadlly Your battery cant hold the juice anymore because it was recharged to zero few times too many , sorry
This is crazy. I just came to xda to post my bionix 1.3.1 battery problem. I been running it for a week and no issues. But this morning I took the phone off the charger and within 10 minutes of using it I was down to 85%. Usually after my morning usage I'd be around 93-95%. But that's not the issue I wanted to post.
I was trying to wait for Black Ice since Frost had the best battery life of any rom I've tried...just not feeling the Frost theme. So I started to download the Frost zip & got the phone on the charger.
Even after I put it back on the charger my battery life kept going down. Plugged it in at 85% and a few minutes later I noticed it was at 83%

Just go to the market, tap menu and then go to DOWNLOADS
look for GMAIL and MAPS, click on them and then where it says "Uninstall update" you want to click that. Done.

if u updated ,find out which modem the previous rom u ran and reflash it to the modem u had before.

I have the same problem. I have system panel running all the time. When I sleep, the phone sleeps too and uses about 1% of battery per hour. But when im actually using the phone, even if the use is minimal like sending a few texts etc. The battery consumption is far greater than the use. Top apps in system panel monitoring is usually system process and system itself. How do I correct this issue?

I agree with you also. These guys must have some super batteries to get that kind of life out of it. lol.
I thought with a battery this big there wouldn't be much of an issue but if you push this phone it won't last the day.
I have screen set to auto, manual sync, data off, wifi off, gps off and here's how I got on today.
6am Of charger and 5mins checking email twitter then wifi off
7 hrs radio and music player,
Then through out the course of the evening I checked emails etc again for a max of 15 mins.
Phone turned of at 8pm so thats 14hrs but that was 14hrs with everything turned off and not really using the phone, my Desire S I used the same way and at this stage of the evening it still had well over a 3rd of battery left almost half. I installed Juice Defender yesterday and it made no difference.
Is this type of battery life normal for this phone?

Keep in mind I am using Ninphetamine 2.0.2 kernel with villain rom 2.4.2, juicedefender, and did a proper, full battery calibration.
Today I played about 2h of games, listened to music for about 3h, and then did random things like checking email, downloading apps from market etc. I have only Wifi and autorotation always enabled. It's been about 12 hours since I unplugged it, and I am at 83% of my battery life. Looks like I won't have to charge it for 4-5 days using it regularly.

If he had mobile data and the phone turned off and just on wifi that's doable.
Listening to music with the screen off is a pretty low consumption scenario, cos the cpu will hit 200mhz and the dps' will be doing most of the work.
And considering that the screen and the mobile data connection are #1 and #2 users of power!
Doable but still maybe a slight exaggeration.
The phone has a very low idle draw though, so when its just sitting there not doing anything in deep sleep, you know you wont find your battery dead which is good.
Do people really not have access to chargers in a 12-24hr period? I don't get this whole batt life issue. Yeah,they suck, but seriously, who can't plug their phone in for 20-30mins a couple times a day?
oh and I deft call BS on not having to charge for four days. Never going to happen. Even if you dont touch your phone at all for four days. Still won't happen.

Doing a factory reset before installing anything is becoming the gold standard.
Hope it helps you.
I get between 7-9 hours of active use. Sounds like some process is running amok on yours. I didn't factory reset when I bought it either....though I have rooted it since then, but battery life is about the same pre and post root.
You might want to consider a program to monitor battery use to see what's eating it up. Maybe do that before you factory reset it so you don't install the same thing again.

System panel is a good app to find what's using your CPU and better batterystats can help find what's keeping your phone from going to deep sleep. An easy way to see if this is the case is go into battery setting and select the first option(history details). Compare the Awake bar with the screen on bar. Those two should be nearly identical if not then you have a rogue app.

The one I've seen mentioned several times in here is BetterBatteryStats. I just don't want to drop $3.00 on something I don't need. It might help your issue though.

have you flashed any kernels or roms? sometimes this makes the tablet report the wrong battery stats for a bit.
did you run the battery down until it turns off and then give it a full charge? sometimes you have more juice than what is being reported. ive been stuck at 1-2% for over an hour before. Most likely its a rogue app though, system panel and better batterystats should find out what app it is. if they dont then it could be that you have a defective battery...
Been on mine continuously for 3 hrs 18 mins and at 60%. Excellent if you ask me. Next step up in battery life would be Transformer series with dock.

Hello everyone, i purchased my Nexus 7 and it arrived in the mail 3 days ago. And as with every other Android device ive ever owned, the batter is absolutely terrible. I get about 2hrs on screen time when browing the web and maybe playing an occasional game. Does anyone have any idea whats going on? Or have any way to help? Thanks so much

Quite the opposite for me; unlike every other Android device I've had (Nexus One, GS2) the battery life is excellent. I watched 720p mkv video on the train yesterday for a good 3 hours, and still had ~70% by the time I got home, from a full charge.
The battery life is excellent, as far as I'm concerned.
Scoutamis said:
Really? Like as soon as you set up the device, you are suppose to factory reset it? And since im facotry resetting it 3 days into having it, do i have to calibrate the battery again?

Don't think you needed to calibrate the battery to begin with. I usually get fine battery life without doing anything special.
Something must be causing the poor battery on your Nexus, Yesterday after my N7 was fully charged, I watched the movie Thor for 1hr and 54 minutes n and my battery only dropped to 83%.
I'm at 16 hours and 52 minutes with 3 hours and 44 minutes of on screen time, the battery is at 51%

My N7 is completely stock and has never been rooted. I also did do a couple charge cycles which didn't seem to help much. And better batterystats has AudioOut_2 at 38% (while I'm playing music) but other than that it doesn't seem to be a rogue app

Download CPU spy from the market to see if the tablet is sleeping properly, and what frequency its constantly running at

Unless you listen to music for over 5 hours or streaming the songs it shouldnt use that much battery. If you can't find a wakelock with better battery stats then it might just be a bad unit.
Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!
If your saying you left the screen on over night, meaning the phone never went into deep sleep.. If you slept for let's say 6 hours and the phones screen was on for that whole time it's normal that it went down to sixty percent battery.
Maybe I'm understanding your post wrong? Btw I cannot see the picture you posted.

Turn off mobile data and lower the screen brightness to 0 during the day. Also disable WiFi when you're sleeping. I also make sure all apps are closed using the app manager button on the far right.
Mine's been fine following this logic.
Oh sorry, I should meant sleeping overnight, whilst I slept cosily in my bed.
I'll reattach the image in a second
Ah, you won't be able to see any links till I've gone past 10 posts. Back in a bit then, ha.

This is NOT the answer. His battery in the image has dropped 7%. If he hasn't used the screen much it is perfectly understandable that screen might not be a large percentage of that 7%. As he uses the phone more screen will use a larger percentage of his battery and Android OS will use less.
If he gets to the point where the screen is on for an hour or two and the percentages are still like this then yes there is a problem.

My android system has never been that high, regardless if I used the phone for 10 minutes or 10 seconds , or not at all.

Actually No the "Screen" should not always be at the top of the stat list. If you use the phone more than it idles, then yes... but if you are like me, mine says "Phone Idle: 20%" (which is on top) and "Screen" is 4th on the list with 12% (Wi-Fi and Cell standby above it) [this is my personal phone, and I mostly use my work phone. hence the high Idle & standby]
I was having an issue with my phone running out of battery, with very little usage from it. I mean very little, I might make 2 calls from it each day, and respond to an email now and then. I found that an App was preventing my Screen from going into "Deep Sleep" or even "Sleeping" possibly. So I uninstalled all apps (well I only had like 4 additional apps installed), except for 2 that I need (Google Voice & Drive). Powered off the phone, charged it fully, then powered back on. Its been running on the same charge for 24+hrs now and reads 68% battery remaining.
So check the apps you have installed, some use background data, and might be causing problems...

And your phone is the definitive guide for what Android OS usage is? Maybe his phone woke up those services for a period of time longer than normal.
The answer of "lol looks wrong root and install kernel" is terrible advice when so little information is given.

A longer battery graph would help a lot. If yuppy want top search XDA there is a free app called better battery stats that will help you diagnose if something is running in the background eating battery or even if your phone I'd properly entering deep sleep.

See now it is much easier to see that you actually do have a problem and what it is. You have the wakelock problem as you can see from Better Battery Stats which falls under Android OS on the other screen. It also appears that you have somewhat weak signal which could cause the wakelock to drain battery even more. There's not much you can do about that wake lock, some kernels have patches for it but those have their own issues as well.

Could I just install any kernel on stock android and be OK with it? As I've said I've no idea what's best for me; just something nice and clean that doesn't have issues like this. I live onsite where I work so my WiFi is pretty much on all the time if that helps in anyway whatsoever
I'm gonna let it run down completely tonight and charge it, but I don't expect it to help much.

I never told him to install a kernel. The advice I gave is to do a reset then I asked if he was rooted or running a custom rom or kernel because that might of been the problem.

Fully charged overnight, battery still sinking like a ship. 45 minutes and I'm already down to 94% already!
Idiot question; will installing a kernel just solve this? For now as a new guy I'd like to keep it as stock as possible before fiddling with it.

The battery on the n4 seems horrible.
I'm completely stock I just got my phone yesterday, I charged it to 100% now its at 64% battery with only 47 minutes of screen on time.
on the s3 I would be around 83% with 47 minutes of screen on time.
I'm gonna unlock the boot loader and root soon and try Franco kernel I've been reading good things about it.
Sent from my Nexus 4 using xda app-developers app
The battery life on the stock kernel isn't great because the CPU management isn't optimized well. It ramps up the CPU (frequency, number of active cores...) very easily and keeps it there long, which removes the occasional lag but sucks more battery. Flashing a more battery friendly kernel would definitely help you if that is the root of your battery issues and not a badly coded app.
Franco's kernel is a very popular one, and very battery friendly compared to stock (and that doesn't mean you lose performance). It is the one I'm currently using. Most people report of screen on times of 4 or 5 hours. With not so heavy usage and wifi (not 3g) I can also pass 5 hrs.
To install a kernel you need to unlock your boot loader and install a custom recovery. No need to root, but.. why not since you're at it
You can try different kernels with the stock ROM. You don't necessarily need a custom ROM. Just be careful to read the dev's OP and instructions, and definitely not to flash a kernel for another device.
Also another thing that reduces battery is your mobile data, if there are a lot of programs that sync on the background. You can use a program that turns off your mobile data when your screen is off and switch it back on just for a sync every xx minutes. Juice Defender is such app, though I like to use Tasker for that. If you use Tasker and are interested in that project, ask or send me a pm. It works great.
