Android OS Battery Drain - Nexus 4 Q&A, Help & Troubleshooting

When my Nexus 4 is idle "Android OS" kills the battery.
This is even after a factory reset.
I'm on the stock ROM.

Must be a wakelock problem. Check to see if you have a rouge app. Your device is not going into deep sleep.

Nexus 7 battery drain

Hi. It has been two weeks since I got the nexus 7. At first, the battery lasted for a long time. Now I'm realizing that it is draining much quicker than it is supposed to. What should I do?

Better battery stats to check the wake locks and cpu spy to see if your device is deep sleeping

Battery life is horrible!

I purposely left my phone off charge over night to see how much battery drains. In 8 hours it drained 20% with is wrong??

Sounds like your device isn't sleeping. My standby battery life is excellent, less than 1% an hour. On my old N7 I had to turn WiFi off to get good standby, on this one I usually just leave it on as it still doesn't lose anything to speak of.

So yesterday I spent the day rooting and installing CyanogenMod and still I'm losing 2.5% battery an hour in standby/sleep mode! What's the deal?

Deal is stock will always give you the best battery life. Also, ROMS usually take few days to settle after flashing.

Get the app Better Battery Stats to find out what's keeping it awake.

Your battery stats will not be accurate until you drain more of your battery.

Shell process battery drain

Suddenly I noticed that at least 50% of my note battery is by a process called shell which keeps the cpu awake

Battery stats.

I have noticed that every time I reboot my phone battery stats reset itself which is very annoying. Is this the same in your devices?
