Why does my phone keep shutting off for no reason?

[AC Question]

My phone keeps shutting off for no reason.

My phone keeps shutting off with at least 1/2 battery life. It acts like its dead compleetly. It wont come on for at least 20 min. The last time it did it it got real hot, now it keeps restarting. I have a non removable battery and a virus protector. Please help?

So, just try to google battery calibration. In some words: full discharge, disable phone, charge again without turning on, turn on and just put on table for 30 min(don,t try to do anything), again charge from around 95% to 100%. It helps me
