Why Does My iPhone 11/XS/XR/8/X/7/6s Get Hot and How to Fix It

1. iPhone Case

You must feel shocked about cases that will make iPhone get overheat. In fact, it truly does. Especially in summer, the outside temperature is high enough, and the case will stop the heat dissipation. iPhone will get hotter and hotter. So the solution is taking off the case when the temperature is weirdly high.

2. Bad Network Connection or USB Connection

In areas with poor or reduced network connectivity, iPhone has to expend more time searching for and maintaining network connections. This uses more energy which causes the battery to heat up.

4. CPU Usage Issue

If your phone is heating up, you may have a lot of applications open. Also, if you were playing a lot of games, then you can expect an increase in CPU usage and temperature as well. Games, Data Usage (Facebook, Emails), Fetch/Push Data, Possible Solutions can contribute to an increase in CPU Usage.

Possible Solution
