Battery drain after upgrading to 5.1.1.

[VladV]

Hi guys,

I have a problem with my Z1 Compact. After upgrading to android 5.1.1., my phone battery started draining very very fast. Especially when I am on mobile data or wifi. After 10-15 minutes of using data or wifi, my phone shuts down. I read most of the post here were people have/had the same problem.

I had my phone reset to factory settings already - > nothing

I read about a bug that android 5.1.1. has that when you are on data or wifi it continously enables "mobile radio something" and that may be one of the reasons.

If you have any ideas how I can fix my phone, please share.

It's getting anoying already. My phone powers off when I most need it.

Thank you !

There a couple of threads here with people experiencing the same problem (I'm one of them)

Some people have had succes with software repair via PC companion (I'm not one of them) or with removing stamina mode (turn of stamina mode, remove app from phone, restart phone)

You could read up on what other people have tried and try for yourself...
