Why after update IOS 16.7,my IP11Pro heat up hot while play games

Hey there Alcy79,

With regard to your question about whether it's preferable to use the protective case or use graphics-intensive games/apps, that ultimately comes down to your preference. What we would want to note is that if your device ever gets too warm, to the point that your iPhone could sustain any sort of internal issue, the device will automatically alert you and turn off the display to help regulate the temperature. The article shared above has more information:

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 helpful!

Have a great day.

Hi Alcy79,

The following steps address what you're describing specifically, and should provide a solution:

"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.
