I have the same issue. Full re-charge last night. It was in sleep mode for 4 hours and it was at 93%. Checked battery usage, and Google Maps was at 27% - Display 30%.
Seems odd to me since i never opened up GMaps.

Maps has been OK for me. But drained 40% in 5 hours with no use

you guys all stock rom? or oc?
Mine was even better. the first night after the 3.1 upgrade it stayed at 100% for couple of hours...
in fact now even with oc tiamat 1.4.2 kernel, it is 1% / hour if very light use, 10%-15%/hour if watching videos.

Stock here. auto-screen brightness. no task killers. Only change post 3.1, was buying Bang Bang Racing.

Stock haven't changed anything

Sorry, mine was wifi xoom. How about yours? 3G model?

after the initial 3.1 upgrade i did feel like my battery was dying fast but I did not have to charge the Xoom From Thursday Night until Sunday Night and I used it all weekend.
With Tiamat installed and SetCPU lowering CPU usage while screen is off, I dont think I'll ever need to charge my xoom again

3g model

Sorry my experience may not speak for 3G users.

My 3G Xoom depletes itself at about 3 times the speed of my ipad...playing angry birds or simply reading rss news feeds. From 100% to 29% in a few hours.

Do you guys have any background updates running? I have the wifi xoom and mine last 2 days with medium usage with background updates on.... just curious...

Nope no updates. So weird because battery lasted forever before the update

Weird... just checked mine, android is at 18%, maps at 27% screen 28%, idle 15%

My battery drain is about the same

Ok just checked mine. Android system . 49. Screen 29. Everything below 5% what the heck is going on

I had the same problem with the battery running down very quickly. Did a factory reset, reinstalled my apps and everything's back to normal. Good battery life again.

I get about the same as you do with pretty heavy usage. I haven't put it down much since I purchased it, so I can't really tell you how long the battery lasts with mild to slight moderate use.

Screentime 9 hours with 50 percent? That's very good!

I get about 7hrs to 7.5 hrs (Screen On, Awake is about 1hr more) with moderate use. It just depends on what you are using it for. I'm never over 50% brightness, at night its at the minimum brightness possible plus I use Screen Filter app (lowers the brightness even more). I tried to turn off wifi when I'm not using it, for example in games.
Admiral could you tell us if that 9hrs are screen on and how you use your tablet (wifi on all the time, browsing, watching videos, games, etc.)

Regarding battery life

Hello
Long time Hero user who switched to blackberry and now back to android. I've had note 2 for 3 months now and I'm actually disappointed from its battery level. Not that its not enough. .it just didnt live up to its expectations
Through constant whatsapp messaging only (today) 40% drained in 7-8 hours. . I know its a long time but shouldn't it last longer or is 3g that much of a battery usage?
Also does charging with a 2a non official charger might affect my battery? And with the time frames I have available for charging I can never get a full charge. .does that matter?
And is pile stocking on applications and games affecting my battery? Even if they are not open? (Currently using go power master for that)

Show some screen shots of the battery graph. I was just wondering what was your screen time to get a better idea.

You can click on that little chart to see a more detailed view of your battery consumption. Your battery life is a bit on the short side (compared to mine at least), Im guessing the screen is the culprit. Do you have brightness all the way down? How much screen time does the phone get?

@Shei77
For me is battery consumption pretty fine. It depends of course what I am doing with the phone through the day. For example yesterday after whole day "playing" with phone from time to time I had around 70%. I am chargin it when I go to sleep because still if I have in the morning 30-50% it wont make it through day when I dont have option to charge it. Just to add, I have Wifi and GPS always on.

If constant messaging for 7-8 hours means the screen being on for 7ish hours, you have ridiculously good battery life at 40 percent..

I'd say your battery life is fine, im guessing maybe even better than mine. Im doing 6h 37m right now with 69% left, H+/3G always on, with moderate screen time and a bit of gaming.

Huh..what about charging?
Also any tips for extending? Ram keeps filling up after some time..is it cause I have a lot of applications?

As shown from your screenshot your phone signals are really bad. That might be contributing to the drain of the battery.

I think your battery life is fine :good: Usually with my note 2 i can do 4 display hours and 1 day or more of battery life. 3g/h+ always on, lumi 50% all sync on, calls, gaming and web.

This is the current on screen which is a few hours after the first screenshots
What can I do about signals? And if I have a lot of apps do they consume battery through background?
Sent from my GT-N7100 using xda premium

Really, your battery life isn't that bad. The 7 or so screen time hours you'll get if that continues, is pretty good!
And to your other questions, charger type doesn't affect battery performance. Charging time should take around 2,5 hours from 0 to 100, if you're far away from that, the charger might be at fault.

Charging usually takes 3 hours for a full charge and according to my charging current its using 1698mah

I updated it just a couple of days ago I need an expert opinion on how good my battery's time is.

^No offence, but without screen on time a battery stats is just meaningless!
So kindly post your 'Screen on' time.
@shei77: You're on H+ and you're having almost three hours screen on time, with 60 odd percent left. That is very good battery life.
'Swyped' from my GT-N7100

Maybe a bit OT, but what I have noticed is that when the phone reports fully charged, Elixir widget still displays 1600mA being charged into the device? Also, when the battery is full at 100%, the phone is still pretty warm! I don;t remember my HTC did that? It was warm, but when it reached 100% it cooled down and was not hot anymore... I tend to keep phone in charger in the evening because I use wifi hotspot....

My battery life is awesome I'm on cm 10.1 rom with uneak kernel, cm 10.1 is smooth and great performance and great on battery life,
I have attached a screen shot of battery stats...

You probably have a battery drain. Try this: charge your battery till 100% before you go to sleep, leave it in standby over night and see how much power you loose. My 9005 goes from 100% to 96% in 9 hours of standby, which is pretty good. If yours loses much more, you probably have an app keeping your phone awake. A first check would be the location tracking settings in Google maps. Switch location report and location history off. They are famous battery drainers.

Wifi. I was pleasantly surprised myself I didn't try heavy screen usage yet, but with normal use including telephone calls, navigation, note taking etc. I get through the day easily without extra charging. A normal day for me lasts from 7:00 till midnight, with 30% battery left at the end of the day.

Sorry, probably I was not helpful. Just saying I am running an SG3 on CM and that is exactly what my battery usage looks like, I hope you get it fixed an d I hope it is not indicative of the SGN3 that I'm getting my hands on tomorrow. Cheers.

Not to rub it in, just to show you that a good battery life ís in fact possible: on 4G/LTE the battery power went from 100% to 98% in 2,5 hrs.

Nexus 7 battery drain overnight

I purchased a nexus 7 recently,updated to 4.3,locked and unrooted as of yet. I currently have 2 user accounts active on it. Since my first 100% charge, I have been getting tacky battery life. I follow the 100% charge and discharge till 1% method. Overnight with WiFi on and all apps closed,I'm getting a drop from 74% to 57% . Looking in the battery stats doesn't help as it doesn't show any unusual ongoing background activity. I'm also getting around 6 hours Screen on time,I could never exceed this mark. I only have the customary Google apps,Facebook,Twitter, instagram,pulse,and 3 games installed. What can be the reason of this ?
Sent from my Nexus 7 using xda app-developers app

Those apps keep running.. Also some third party apps push ads and also turn screen on, which could drain battery..
For better battery life, you can turn wifi off if not needed,.
Sent from my Nexus 7 using xda app-developers app

I tried with WiFi off one night, I got around 9% drain still. I kept the sync interval at the maximum in every data fetching app I have installed too.
Sent from my Nexus 7 using xda app-developers app

You might well try the app Better Battery Stats, and see what it believes is keeping your tablet from going into deep sleep. 9% drain overnight is not terribly excessive -- it should be more like 5%, I guess.

My 2012 nexus 7 had 51% before I went to sleep last night and when I woke up this morning it was completely dead. I didn't even get a charge icon when I plugged it in to charge. I had to leave it for an hour then tried again and it fired right up.. Hope I can see what's causing the drain with better battery stats
Sent from my Nexus 7 using xda app-developers app

I was using mine once in the morning,when the battery hit 4% it suddenly shut down. I tried to charge but the battery icon wouldn't show up. Started it finally using the tips on the Google support site. Must say,I've been plagued with battery issues. I'll try a factory reset and while on it unlock the boot loader too.

I checked with BBS with WiFi off overnight. "PowerManagementService.wake lock" is keeping my N7 awake. Any solutions?
EDIT: I checked in partial wakelocks,AudioOut_2 was the highest at 30m runtime.
