Xperia Z2 battery draining quickly..

[Bhargav4000]

I have this problem since the firmware update to 17.1.2.A.0.314 on my Xperia Z2. My battery doesn't last that long. I lose about 1% battery a minute. I didn't have this problem before the update and I find it hard. Please help me with a solution.

Xperia Z2
Model: D6502

Thanks in advance,
Bhargav.

I suggest you go for a software repair:
