Hello khush272,
Thank you for using Apple Support Communities and for sharing the details with us. If you notice that your iPhone feels warmer than usual, this can occur under specific circumstances. The following resource explains more in-depth why this might occur and which steps you can take to address it. Click here: If your iPhone or iPad gets too hot or too cold - Apple Support
Your device might get warm
You might notice that your device feels warmer when you:
* Set up your device the first time
* Restore from a backup
* Wirelessly charge your device
* Use graphics-intensive or processor-intensive apps, games, or features, including augmented-reality apps
* Stream high-quality video
These conditions are normal, and your device will return to a regular temperature when the process is complete or when you finish your activity. If your device doesn't display a temperature warning, you can keep using your device.
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 hope this information is useful. Thank you for using Apple Support Communities. Take care.
