Most of the time when people think that their phones overheating, it’s actually not. Just because it feels hot in the hand, doesn’t mean something bad is gonna happen to it. Phone and computers can withstand high CPU core temps these days. A useful tool is System Tuner. It is a popular android app that allows you to monitor the real temperature of your phone’s CPU. It is also a wise thing to avoid bulky or cases that completely cover up your phone, as they could block the phone’s heat from dissipating.
