Preliminary Fixes

Cool down the iPhone

Many problems are observed within the iPhone due to the overheating issue. Many a time, users tend to forget that they are using their iPhones in bright sunlight areas or in places which is extreme temperatures. This causes the iPhone to start getting heated.

Therefore, we suggest our users try cooling down their iPhones and see if this helps.

Turn Off Always On Display (Only for iPhone 14 Users)

This applies to only iPhone 14 users where there is a newly introduced feature called Always On Display. This feature dims the brightness and displays some necessary widgets, time, etc on the screen even after it is locked.

This makes users feel like the screen is dimmed and not locked. So try turning off this feature by going to the Settings app and selecting the Display & Brightness option. After that, scroll down and disable the Always On option by tapping on its toggle switch as shown below.

Auto-Brightness is an option available on the iPhone that adjusts the screen brightness level depending on the surrounding. For example, if you are inside the house in a dark room, it reduces the brightness so the user can be comfortable viewing the screen.

So try turning off the Auto-Brightness feature on your iPhone using the steps below.

1. Go to the Settings app on your iPhone first and select the Accessibility option by clicking on it.
