4. Hot Environment

As mentioned before, direct sunlight was the reason my iPhone 13 overheated when charging. However, any external heat source can lead to overheating as well.

So, avoid placing your iPhone in direct sunlight or a car on a hot day for an extended time. Instead, place it in a cool room with moderate airflow. It can also help to remove your case if it is blocking airflow and trapping heat.

5. Heavy Background Processes

It’s normal for your iPhone to be warm when charging. However, if there are many background processes running during charging, it can lead to overheating as well.

To avoid this, close all non-essential background apps. If you want to go a step further, open Settings, go to General, and Background App Refresh. Here, select Background App Refresh and tap Off.

In addition, once your iPhone has reached a normal temperature, update iOS and all your apps. Apple and app developers frequently release software updates that can include bug fixes and optimizations to help prevent overheating issues.
