My phone is a few years old and before the weekend it randomly started powering off/shutting off after the 10 minute mark. When the phone goes into sleep mode, I can’t wake it back up. I have to hold the power button down for 3 sec and go through the startup. It never shuts off randomly while in use, only when not in use in sleep mode. As long as I continue to touch the screen before 10 minutes (longest setting I have to keep it awake) its fine. I cannot figure out how to resolve this issue. Any suggestions? Things I’ve done so far:
- Cleaned charging port
- held down volume down and power to open in “safe mode” and to manually restart
- messed with setting to see if apps are draining my battery too fast and the phone thinks its trying to save power by shutting down.
