Z5 draining the battery so fast... Even on sleep mode.

[CharlesJ]

I sent my phone to be repair under the Sony warranty. According to the return form, the battery was replaced. The phone seems to be working just fine for a week or so. Yesterday it starts draining the battery so fast. Customer support says the phone lasts 2 days on standby mode(what!). Thing is, that the OS and the Android system appears to be the ones who are draining must of the battery, sometimes, even more than the screen itself. The Android system and OS have shown before 18 to 20% or higher. The barcode app I rarely use it...

Sir, yes sir

[CharlesJ]

Have you ever had this kind of problem with your Z5's?

[Uliwooly]

Yeah, but it was an app acting up (google services/app)

[CharlesJ]

Hey! I tried the safe mode and it's about the same.

Post both screenshots

Screenshots were taken right after booting from safe mode to normal 

Those were this morning. 

I just got home like an hour ago and the phone was dying.
