Factory reset and do NOT choose app or app data restore. Uncheck these 2 checked boxes.
SKIP step 5.
This is my usual process and I have had no issues.
The reasons for disabling app data is due to the fact that DAVLIK is now ART and the Android Optimization process might not go as planned if you just slap the new OS over the old OS. Also, when you go back to the Play Store to download apps, they will be the correct version this time for this OS.
screen , cell standby, android system android os , i have lost almost 10% battery in an hour and all i have done is is send a few msgs on hangouts
There is nothing unusual in the battery usage stats , nothing extra running , nothing showing extra use , and there is nothing different on my phone since update , there is actually less !!
Battery stats need resetting. Let the phone die, then recharge while off. Then let it settle in. Sounds dumb, but it usually works.
What % is your batter at right now?
It's promising that the OS aren't the top 2 items, though not the best they are high up there.
Just to verify, when you did the factory reset you disabled app data back up and restore prior to doing one?
and i disabled everything , i had to completely start from scratch i have not even redownloaded several things i had on my phone previously
and sorry i thought i had said i recalibrted the battery but i am not seeing i posted that , so yes i let it die completely and then charge while powered off to 100% the turned it on left it plugged in etc
