Whether you're texting, scrolling through your socials or playing a game, a phone screen that keeps dimming can be a major annoyance. Why does this keep happening when your auto-brightness feature is turned off?
There are a few possible reasons your phone screen is dimming, and there are also a few ways you can try to fix the dimming problem yourself.
One of the most straightforward explanations is that your iPhone is overheating, either externally or internally. When the phone gets hot, it's designed to cut back on energy and performance to maintain a stable internal temperature. Considering that the touchscreen is one of the most power-hungry features of a phone, screen brightness is scaled back as a precaution when the phone gets too hot. But phones can also overheat when you're running apps that require extra power, like gaming, using the camera, streaming HD video, updating software or wirelessly charging your phone.
Whether the heat is from internal or external sources, get your iPhone into a more comfortable environment so it has the chance to cool off. If your iPhone is in a protective case, take it off so more heat can escape. And be sure to close down any power-hungry apps or tasks you're running on the phone to let it stabilize.
Another reason that your phone's screen is dimming may be that your phone's power-saving settings are enabled. This feature certainly helps your iPhone maintain its battery power between charges, but it can also cause the screen to dim as a default way to save power.
