Why Does my Brightness Keep Going Down: It’s likely that your iPhone’s light varies occasionally if it’s up to date. This might be because of Auto-Brightness, a feature that automatically changes the brightness of your screen to match the ambient light level so you can see more clearly.

Why Does my Brightness Keep Going Down

Another function, Night Shift, alters the hue and light of your iPhone at specific times, usually between sunset and morning. You can do this after looking at your phone and before going to bed.

Why Your iPhone Keeps Dimming

Your iPhone dims frequently because Auto-Brightness is activated most of the time. The Auto-Brightness feature on your iPhone automatically adjusts the screen’s light based on ambient lighting.

Auto-Brightness will dim your iPhone’s display at night when it’s darker so your eyes won’t be blinded by what you’re viewing on the screen.

When you’re at the beach on a bright, sunny day, Auto-lighting will typically turn up the light of your iPhone’s display so you can really see what’s going on there!

If you wish to stop your iPhone from darkening, you must off Auto-Brightness. Tap Accessibility -> Display & Text Size in Settings after opening it. The switch adjacent to Auto-Brightness must then be turned off.
