Consider when the problem began to assist you to figure out which app is the perpetrator or causing your iPhone to overheat. Was it after I installed this new gaming app or after I downloaded this new movie when it started? The fresh download may have crashed or become corrupted in this situation.

• Go to Settings->Privacy->Analytics->Analytics Data to see which app has been crashing on your iPhone. You'll see a list of apps and services that have been crashing, as well as the log files on your device, under the data area.
