Battery issues with 4.2.1?

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,

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.

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...

Battery drain with 3g on terrible

Hi guys,
Is anyone else get terrible battery life with 3g and data on even on standby? I believe the phone function drains the battery and it lasts only 2 days or so on standby. I constantly have the tab on flight mode with wifi enabled and battery is much improved to about 1 week standby. Anyone else? I am on stock 4.0.4.
Thanks

Wtf r this guy even serious? I wish i had 1 day standby, what a joke

Hi Iong. We are talking about a tablet here, not a phone. Tablets should have 1 week standby at least. The battery drain with 3g and phone on is unacceptable. I think the reason is the connection to phone signal which is constant.

Mate 1 day pr 2 day standby is a lot, given the fact you install many program and it constantly connect to tinternet to check for updates notifs etx. You dont have 1 week standby whatsover, forget it. Big tablet big baterry big screen. Ot all goes scaling together

So 'l2_hsic' and 'batt_work wake lock' are the 2 processes keeping my table awake for 5 hours in total since yesterday. Any idea of what these do?
Thanks

most likely is that one or more of your apps is causing the problem. try a reset and see if the problem goes away. if it does, install apps one by and and check which one is the problem

Use juice defender ultimate in tablet mode. I can go several days idle time and lose almost no battery.

wow guys are you all serious??? i lose around 10-15 percent overnight man

Dude.. My phone was on 60 percent at 6pm once when I slept... Next morning at seven it was off... Wifi off data off.. All **** off... I dint even get a call or msg... Definitely not 1 percent I guess...

If I leave data and WiFi off, about 2% to 10% but that isn't usual. When I am home, I leave WiFi on and that gets my currents and YouTube video preloaded. 15% to 20% Max. I rarely leave it to charge overnight.

REBOOTED - nothing, drain battery like hell, lose about 30-40% in 5 hours...
I woke up with 15-20% battery drained... wtf guys ?
I kill all apps, turn of data, wifi and etc, still nothing...
BATTERY STATUS - messaging use 84% of battery... wtf ?

To all of you having problems with battery drain, you should know that last Google Maps update messed up the deep sleep state of the system.
I´m running Carbon ROM, but also tested with other 2 ROM´s and the results were the same, around 20%-25% battery drain over night.
I read that disabling "Reporting Location" and "Location History" under Location settings in the Google Settings app(the one with the green icon) helps a little, but still is an issue.
With these settings disabled, I get around 5% battery drain over night. Although the wakelock has decreased, is still there waking up the device. Already reported to Google to see if they can do anything to fix it. The wakelock appears as "Android System" or "Google Services".
Before update I had around 3% battery drain over night(around 8 hours) with WiFi.
Hope this helps.
:fingers-crossed:

As a battery life druggie, I get 1% max. Regardless rom. Usually wifi off and 2g data on. (wifi on is bad for HUMAN DEEP SLEEP).
A not sure useful or not hint, set pm.sleep_mode=1 in your build.prop
Disable everything you can think of. Wifi, gps etc.
Uninstall bloatwares, replace with downloadable ones, use greenify to freeze them.

[Q] Nexus 4 Battery Drain

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

:silly:

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...

Did you mean when the screen is off? Because obviously it status awake while the screen is on. But there may be an app keeping it awake. Make sure all your apps are trusted

and all the apps ive downloaded are from Google Play Store of course.

I'd go for a wakelock detecting app like "better battery stats" or "wakelock detector" to see which app could be the culprit. "Greenify" could then be used to block that app from keeping your tablet awake.
I personally do have no issues with standby whatsoever. I'd say I lose about 3-4% of battery during the day on 4.4. (WLAN and sync on all day, but I'm taking it to work where I have no WLAN I could use). I guess I had the same mimimum drain on 4.3. So standby couldn't be better on N10 in my opinion.
I only had one issue so far, where at about 25% of battery left it suddenly began to drain like 10-15% an hour, thus leading to my N10 shutting off after about 2 hours. No idea what caused that drain in standby.

I second that, get better battery stats or something similar to see what's keeping it awake.

mhm ... will not install 4.4 if the battery life is that terrible. Did you guys control the typical Google apps, which usually like to eat a lot of battery?

I have this since 4.4.2 on my Nexus 10 and 7v2. Not on the 5. My N10 uses almost every juice for Android OS. Before it used 5% for 1-2 days for standby. Now 3 hours. See screenshot. Is this normal?
And it wasn't awake. See other screenshot.
