I’ve been receiving the message, “Some apps or processes are overloading the system ( CPU) and must restart”, since July 4. Battery drain has been about 39% - 50%, overnight while sleep. Is dead in the morning if I go to sleep with 39%. Is half drained after a full charge before sleep. No problem during the day. Ive cleared app cache, wiped partition. I don’t have social media or gaming apps on phone. Started after I installed android message app, but I uninstalled on the 5th and I’m still receiving this error. Android System is the highest % of battery usage. Sometimes it gets up to 59%. Tried toggling between its ability to allow background usage. No difference. Same issue. Have had the phone since mid-March and has been working week; no battery/charge issues. Help!
