Hello-
Ever since I updated to 4.2 and especially 4.2.1, battery life has not been the same. Today I went from 100% last night to 73% in 22 hours just in standby. I didn't change any settings that I can remember. Can anyone please help with this?
Thanks,
wws12

I had the same battery issues on 4.2 in standby...even with wifi disabled. I ended up flashing back to 4.1.2 and battery is back to normal. To me 4.1.2 is more stable and much smoother. Hopefully Google will fix these issues in the next update.

I noticed that a large portion of the battery is being used by something called "Media server" Any idea what that is or how to turn it off?

I'm also noticing the same sleep mode battery drain on 4.2.1,around 1% per hour..
I need to root my tablet to downgrade?

Use media scanner root from the play site and disable the media scanner. Then this battery drain should reduce.

Do I need to be rooted for this?

Yes. Root access is a must.

I think in my case most of the battery issues was from the device being new and the software stats still needed more time to be accurate, that has happened to me on my Sony tablet also..
Now I can see some real stats as I use better battery stats app for keeping track of the battery.
I use my tablet as a use when needed device because it's not my notifications device that is always connected, for that I use my smartphone. That said I turn on airplane mode when I'm not using it and sync when needed as well.
Só when my Nexus 7 is in sleep mode it has very few apps and services running other than the system ones.
So the stats I came up with are:
1% in sleep mode with airplane mode on and Google Now and Location History turned on..
And..
0.3% in sleep mode with airplane mode and Google Now plus Location History off..
So for me no Google Now as I don't need that much.. It lasts 3x more in standby without it... And the truth is, in my country Google now for me isn't that useful as it is although I'm sure someday will be..

It's strange...with stock 4.2.1 no root I haven't any battery drain... 0.7% /hour with wifi on and sync enabled...In the battery stats, even if in a hour i turn on the display on a minute, the display takes at least 40% of battery...

Gotta figure out your wake locks. I lost 0-1% overnight last night.
Best bet is to download better battery stats and gsam battery info. Also CPU spy is helpful for figuring if your tablet is deep sleeping or not.

Also turn off NFC and WiFi. That will help a ton

I've turned off NFC, Location Services and only sync the folders I need in Gmail and i'm down to about 5% overnight. I'll try setting the wifi to sleep when the screen is off and see how that goes.
How accurate are battery stats on the Nexus 10?
Hi guys. Need some help. Very happy with my nexus 4 but, and its a big but, i am having some serious issues with the battery. I am struggling to even get 2 hrs of screen time on my nexus 4. The battery cant be this bad. Is there any way i can see what is exactly causing my battery drain? Sync, nfc is turned off. No widgets r running. Cant understand it. May have to rma this thing.
Help please.

This is probably the cause of your problem.

What kind of apps do you have?? Like apps that you think might drain some battery. Also use betterbatterystat app to monitor what's waking your device.

With stock, around 2 hours of screen on time is typical. You can prolong the battery life by disable Google Now, location service, email sync, Playstore auto update, etc. Check your battery stats (try better battery stats from the store) to see if any third-party apps drain your battery.
The better way to do it is to unlock bootloader, root your phone then flash a custom kernel. I recommend franco.Kernel. 3-4 hours of screen on time is typical with franco.

Might as well flash a custom ROM with it if you're going to use a custom kernel IMO. When a new OTA, OP will have problems updating to it because he is using stock + custom kernel + custom recovery.
Here is how to fix your battery problem.
1. Turn off location access in Google Maps settings.
2. Wait about a week for the battery to go through its charge cycle 6-10 times. Let it get as low as possible without the battery dying (this is really bad) and be sure to let the battery sit at 100% for atleast a half hour or so when fully charged.
Each day you will see your battery life increase and when done, you should be getting around 5 hours screen on time.
Well dramatic change in battery life as displayed below. Now after having a read in several topics it seems like a fix is to have the wifi on. How strange as this goes against the ethos of all previous smartphones i have owned i.e. wifi on drains battery. I have uninstalled a few apps and also switched of location access, so to be sure that the fix is wifi related i will switch wifi off the next time i do a full charge and see how that behaves. By the way android os is way down in battery consumption now.

My nexus 7 was fully charged and I put it in the rack in the night. Next morning it shut down completely. When I switched it on, it showed battery 0% says 0% the same c thing happened today as well. Its a new device. Any idea??

Some app or service is draining your battery. Get BetterBatteryStats to narrow it down.

Like someone said before it's a rogue app and the only way your going to get the battery drain issue to go away is to figure out which app is doing it and then get rid of it.

I think the best solution for you is to factory reset or re-install android on your device once.
It will be easier than finding out where is the problem. as screen snap shows most of the battery is drained by "android OS".
It was just my opinion you can take it if you want.
My battery usage. Even though my screen on time was only about 2 hrs most of the battery was drained by the screen. So there music be something very wrong in your case.
I don't know about android virus but that might be an option.

Gonna follow along and disable my daydream as well since I'm having the same problem you are with it actually draining while on the charger (Stock ROM, Franco Kernel, OEM wall wart with gold tipped USB cable). Tis quite annoying to have to either keep the screen off or power down completely in order for this bad boy to charge...
Recently i noticed that my phone's battery begin drained at night during sleep like about 20% without any use.
i did turn off location services, Wi-Fi, GPS. I don't know what could be the problem for the battery to be drained.
Is there a way to check it?
Use BetterBatteryStats to find the issue. Do you use s2w or touch control? They drain some battery too

I checked battery in Settings and it shows 41% Phone idle and 26% Cell standby.
So i don't think Google Services is the problem here...

0 for me. In fact, the battery gets charged to full over night. I put it on the wireless charger by the bed right before I go to sleep. :laugh:
My device sat unused for two nights and it only lost 6%.
i lost yesterday about 4% in 14 hours. do this ** settings- wifi - advanced - keep wifi on during sleep - only when plugged in ** you will see huge battery improvement. also you can use greenify app to hibernate apps that wake you tablet during sleep

Mine has been very good. Been unplugged for 7days 12hrs, WiFi on the whole time, couple hours of screen on time and still got 20% left. Overall I'm happy.
