If your phone is heating up repeatedly, then turn it off immediately and also close all the apps. This will reduce the extra pressure on the phone and it will heat up less. Do not use the phone in the sun and keep it away from external heat. These can increase its heat.

If the phone's battery is giving trouble, then it can heat up. iPhone also has the facility to check battery health. If you are running the phone on data or WiFi, then turn off the network and see if the phone is heating up less. Continuously searching the network also heats the phone.

Sometimes the phone heats up even due to not updating. In such a situation, if any update has come, then install it. If the phone is not stopping heating up and this is becoming a problem, then you should do a factory reset, but first, take a backup of the data.
