Android battery drain?

[Koala Koala]

Ok guys it's a new issue, but recently my Xperia z2's battery isn't performing as well. It says Android system and Android os sucks a total of 60% of my battery. Anybody might know the cause of this?

As a side note, that's 60% of the amount being drawn, not 60% of the battery's capacity. (If you could add up all the numbers [most of them are below 0.5% and aren't shown] it would always add up to 100% - all of the power being used is being used by something.)

If you recently had an update, Android will eat battery like crazy for a few days. With 3GB of RAM and a 2.3GHz Krait 400, even running a few large apps at once shouldn't slow it down much.

You could try a full backup - all your apps and data (use Helium if you don't have anything else), factory reset, then see whether it's pperforming badly. If it is, it's probably still under warranty, so it's exchange time.

(You could try starting in Safe Mode first, just to see if it's one of your apps that's causing the problem.)
