My New S7 extreme battery drainage with pictures

[bellamy123]

Hello,

My used S7 came in yesterday from Amazon and everything has been fine except the battery. The battery drains very quick. Earlier today the battery went from 100 to 80% in around 20 minutes.

The phone came with G930U software and I flashed it back to G930R4 which is what the phone is originally, then I flashed it back to G930U because Oreo came out for it earlier today.

I disabled Always on Display, device scanning, etc. I even ran ADB and removed Gear Vr and bloatware apps.

Here's some screenshots:

I don't know why the Screen is using so much battery. Any help will be appreciated!

Honestly sounds like your device might be defective. I'd recommend returning it through Amazon and either buying another or buying a better device.

Honestly, you should consider yourself very lucky to get 4+ hours of screen time. I'm lucky to get over 1 hour before I'm running to a charger.
