it might be an app keeping your phone awake, repair your phone with SUS or PCC

from the screen shots i am seeing that your android os is using much battery ie nearly 35% which is quite more(general is 7% to 15%). So i propose to switch off the phone and restart it again so that ram will be freed and do charge ur battery from 20% to 100%(full condtion rather than charging condition) at on go........

one more thing is that the network signal strength is very low.....so might be regular network access is causing more battery drain out.......

If you r not doing any internet stuffs then do switch off ur wifi.......:smileyhappy:

Again if at all u r keeping wifi on, please at least switch off your GPS ........during night time i dont think u will be needing GPS to be on.......:smileysilly:

hope it will help:smileyhappy:

My problem is:this.

How and WHY uses the Android Os so much power: cpu total is 45m 46s,

Its not the 1st time i have this problem, i rly didnt used my phone (after charging it) since i was working (24h shift).

And somethimes when im at 20-25%(battery) if i turn on mobile data i get a battery dropdown in like 5seconds to o%(zero) and the phone switches off. Turning back i still got around 15%.

I have the exact same problem! Have sometimes also a dropdown from 20% to 0%. And sometimes the phone works for hours on 1%. I have this problem since the last update!

Tried everything, reset and a new installation of the firmware!

Have also the camera issue.

Please Sony fix this fast as possible!

And now this

I never had this problem before->

Pluged in for charge and it stucked at 11% for like hours, i did a reset/update with SUS, but something during the night kept my phone awake for like 5hours - constant (wifi off mobile data off sync off) just the alarm was on.

How to find out what app or what keeps the phone awake.

bring it to sony service center since reparing it didn't solve the issue. maybe there is hardware issue.
