Why does the 13 overheat constantly. This is the lousiest phone I have had in over 12 years

Hi Tanglim,

We recommend you try the steps below if your iPhone is warmer than expected.

If your iPhone or iPad gets too hot or too cold - Apple Support

To perform the recommended troubleshooting steps via the link above, complete the steps in the section titled "If your device gets too warm."

iOS and iPadOS devices have built-in protections to prevent overheating. If the interior temperature of your device exceeds the normal operating range, your device will protect its internal components by attempting to regulate its temperature. 

Avoid these conditions and activities because they might change the performance of your device:

* Leaving your device in a car on a hot day.

* Leaving your device in direct sunlight for an extended period of time.

* Using certain features in hot conditions or direct sunlight for an extended period of time, such as GPS tracking or navigation in a car, playing a graphics-intensive game, or using augmented-reality apps.

If the interior temperature of your device exceeds the normal operating range, you might notice these changes:

* Charging, including wireless charging, slows or stops.

* The display dims or goes black.

* Cellular radios enter a low-power state. The signal might weaken during this time.

* The camera flash is temporarily disabled.

* Performance slows with graphics-intensive or augmented-reality apps or features.

Additionally, if you're navigating, your device might show this alert and turn off the display: "Temperature: iPhone needs to cool down." Navigation still provides audible turn-by-turn directions. When approaching a turn, the display will illuminate to guide you through the turn.

We recommend the steps above because they will show you what to do if your device gets too warm.

Please let us know the outcome after giving the above steps a try.

Thanks for using the Apple Support Communities.

Cheers!
