4.2 battery life

[jpash549]

Just installed Advanced Task Manager from app world. Looks like it might help some battery drain problems. Anyone got comments?

Did you guys do a fresh install or did you do the OTA update? I've installed 4.2 fresh on my N7 and my N4 and I'm having ZERO issues. No problems with battery drain and no bugs, other than the December thing. I keep hearing people having all of these issues and blog posts criticizing 4.s for being buggy, but I haven't experience any of that.

I haven't noticed any hit on battery life since the update to 4.2, it's been much of the same.

Ditto. Just checked my N7, 1 day 4 hours on the battery and it's at 60%. And my kids streamed Netflix for perhaps an hour or so. Although, it was idle for a ton of the other time.

Have you turned off the NFC, Bluetooth and location service?
I manually updated my 32 and have had no issues other than it is much faster!

I was running paranoid android before so I had to fresh install, I just ran the 4.2 factory image straight on it.

Everything else works great other than the drain

I, myself, updated via OTA. It shouldn't matter in my opinion. Maybe we're all just paying too much attention to the battery life, and subconsciously expected to be more life?

I believe you can manually update, which probably also fresh installing.

I don't feel battery life has been any better or worse since my 7 updated to 4.2.

I definitely notice the battery drain with the update! My screen is on auto brightness and have nothing special running other than WiFi.

Someone correct me if I'm wrong... I think what's meant by a fresh install of the 4.2 update is if you did a factory reset and install the update before installing any apps?

I did not do the factory reset before installing 4.2 and I've noticed faster battery drain, bluetooth cutting out, and subtle screen flicker. Although, either the screen flicker isn't so bad anymore or I've gotten used to it...

Anyway, I'm considering Doing factory reset and trying the update again. But will a factory reset take the OS back to 4.1 (or whatever version it was when I first got it) now that I'm on 4.2?

That's strange!

I'll be lucky to get 8 hours out of this battery today.

Google really needs to start Project Roadrunner for battery, because this life doesn't last.

So this battery is lasting longer b.c I put it on airplane mode every time i leave the tablet idle for long periods of time. Exchange Services (work email) and ,APS I used for like 30 seconds each and look at their batter consumption! Both were not running in the background either.


Not saying the 4-3% is that much for long term but I literally had them on for 30 seconds each haha

Are you all using Live wallpapers? Two nights ago I realized that l switched my wallpaper to one of the new Live wallpapers that came with 4.2. Of course that was shortly after I upgraded to 4.2 and started noticing the poor battery life. I then switched to one of the non-live wallpapers and my battery seems to be lot better and the Google Services isn't so high on my battery stats:


But Maps is still pretty high on the list and I don't think I even used it!

No change in battery life for me. Getting at least a full day of use off a full charge.

If you are having issues, do a factory reset and reinstall apps manually - not from a backup. Battery drain can be caused by app data/cache issues.
