My S7 Edge started dropping battery charge quickly about 2 weeks ago. At first, it would be at 66% to 67% and go into restart loop because the charge dropped to 7%. It would not actually boot. I could plug it back in and it would be fine until draining to 66% again and going into restart loop again. Now, it works fine while plugged in but will completely drain a couple of minutes after unplugging. I've tried everything suggested in the tips and troubleshooting section except a complete backup and reset. I've cleared the cache, booted in safe mode, tried all kinds of power settings, ran virus and system checks, deleted all apps installed right before and after this started, you name it.
T-Mobile. Android 8.0.0. Samsung Experience 9.0. Knox 3.1. PLEASE HELP!
