If you’ve noticed that your iPhone screen dims when you’re playing games, you’re not alone.
This is a common issue that can be caused by a number of factors. In this article, we will discuss some potential causes of this problem and provide some steps you can try to fix it.
If your iPhone screen dims when you’re playing games, it can be frustrating and disrupt your gaming experience.
This issue can be caused by a number of factors, including settings on your iPhone, the type of game you’re playing, and the age of your iPhone’s battery.
Causes of iPhone Screen Dimming When Playing Games
One possible cause of this problem is the settings on your iPhone.
If you have the “Auto-Brightness” feature turned on, your iPhone’s screen may dim automatically when you’re playing games to save battery power.
You can check and adjust this setting by going to the “Display & Brightness” section in the Settings app on your iPhone.
Another possible cause of this issue is the type of game you’re playing.
Some games may be more demanding on your iPhone’s battery and processor, causing the screen to dim as a result.
If this is the case, you may need to reduce the graphics settings on the game or close other apps running in the background to help improve performance.
Lastly, the age of your iPhone’s battery can also play a role in this problem.
As batteries age, they lose their ability to hold a charge, which can cause the screen to dim when playing games.
If your iPhone’s battery is old, you may need to replace it to fix the issue.

Steps to fix iPhone screen dims when playing games
Here are some steps you can try to fix the problem of your iPhone screen dimming when playing games:
- Check and adjust the “Auto-Brightness” setting on your iPhone. This can be done by going to the “Display & Brightness” section in the Settings app.
- Reduce the graphics settings on the game you’re playing or close other apps running in the background. This can help improve performance and prevent the screen from dimming.
- If your iPhone’s battery is old, consider replacing it. A new battery can help improve performance and prevent the screen from dimming when playing games.
How Much Can An iPhone Screen Dim?
The amount that an iPhone’s screen can dim depends on a few factors, including the settings on the iPhone, the type of game being played, and the age of the battery.
If the “Auto-Brightness” setting is turned on, the iPhone’s screen will automatically adjust its brightness based on the ambient light in the environment.
In this case, the screen can dim to a very low level if the lighting is low.
If the game being played is demanding on the iPhone’s battery and processor, the screen may dim more than usual to conserve battery power. This can happen even if the “Auto-Brightness” setting is turned off.
Lastly, if the battery is old and has lost its ability to hold a charge, the screen may dim more than usual when playing games.
In this case, the screen may dim to a very low level, even if the “Auto-Brightness” setting is turned off and the game is not particularly demanding.
Overall, the amount that an iPhone’s screen can dim depends on the specific circumstances and can range from a slight dimming to a very low level of brightness.
