It’s easy to overlook certain rad iOS features just because they’re not obvious. Nonetheless, we’re sure that without them, the premium nature of iPhone would fall below the expectations. On the other hand, if you are not informed about those features, they may appear to be a weird system issue or 3rd-party app’s error.

One user on Apple’s community forum experienced something strange in regard to screen brightness and we’re bringing you his/hers experience below:

”I turned on the maximum brightness screen and I turned off the brightness mode but why when I turned on max brightness and I played the game for about 10 minutes then my screen light suddenly darkened To some extent but while the light bar in the control center is still the maximum. After I stop playing the game, the screen light will come back to normal after about 10 minutes! I do not understand what is happening on my device.”

You can find the explanation below.

Why may iPhone dim screen while gaming?

As you can see for yourself, this seems like a strange bug. But just on a first glance. This isn’t the problem but it’s rather a solution for overheating. If you have been using your device for the extended period of time, especially playing a demanding game, the phone will, logically, start to heat up. In order to prevent overheating and possible hardware damage, iOS software regulates certain processes in order to ”cool down” the device.

This is a standard practice, so you have nothing to worry about. Just leave your phone for some time and everything, including the screen brightness, will restore to normal values and activity.

These are some features that will be affected by the changes iOS inflicts in order to prevent the device from overheating:

  • Camera flash will be temporarily disabled.
  • Cellular radio will enter the low-energy state which might affect your signal and Mobile Data.
  • The display will dim or turn black temporarily.
  • If the device is plugged into the wall socket, it will stop charging.

If the temperatures are above the norms, you’ll see the emergency prompt that informs you about the current state. In order to use your device, you’ll need to wait for the cooldown.

How to speed up the cooldown process or even avoid heating?

You can speed up the cooldown by unplugging your device from a charger, avoiding sun exposure and just let it be. On the other hand, if you’re keen to prevent overheating, it’s paramount to use your handset only when it’s not charging. This especially comes into play when is hot outside. In addition, don’t expose it to sun or heat sources for the extended period of time. And, finally, if you run graphically demanding games, make sure to take a break from time to time.
