My iPhone 12 mini screen will dim for no apparent reason and it becomes nonadjustable at that point. Also the phone becomes very hot to the touch especially on the back of the phone. I see where this issue was addressed sometime ago. Has Apple or anyone ever resolve this issue or commented on it?
Hi rickautry,
If you'd like more information about your iPhone being warmer than expected, and then the screen dimming, this might help.
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. Here are some of the higher ambient-temperature conditions and activities to avoid, because they might cause your device to change performance and behavior:
- Avoid leaving your device in a car on a hot day.
- Avoid leaving your device in direct sunlight for an extended period of time.
- Avoid 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.
The information above is from If your iPhone, iPad, or iPod touch gets too hot or too cold. This link has excellent information about the expected performance and temperature of your iPhone. It explains what is normal and what is not. If you're using a graphics-intensive app, for example, your device might get warmer and slower. Your screen dimming is also another way your iPhone regulates temperature (see above.) Again, this is likely normal. You can use the tips that begin with "Avoid..." quoted above to help avoid this from happening.
If you have any additional questions, let us know if you've ever received a temperature warning on your screen. Additionally, let us know the names of the apps that you're using when this happens.
We hope that helps with your question and take care!
