Hello All,

i just updated to official android 5.0 (got the update this weekend) using the OTA.
After update the my s4 is very slow, and on top of that the battery is very poor. 5h with nearly no use i have lost 80% of battery.

What could i do?

I searched to disable fast dormancy (like on 4.4.2) but can't find anything.
I have an official build no root or nothing.

Any suggestion?

Thanks
