Would a bad battery prevent phone powering on even while plugged in?
Does anyone know if a bad battery will prevent the S7 from turning on even while connected to a USB power source?
Galaxy S7 won't power on, no safe mode, hard reset, no lights, nothing. After charging overnight I removed the back cover and measured the battery output +/- pins as 2.9V. Nominal running voltage is 3.85V, so I'm thinking the battery is bad.
Is this a good question?
