- Tap on Night Shift and toggle off the scheduled option.
2 Turn Off “Attention-Aware” Features
If you have the Face ID feature turned on for your device, you most likely have the Attention-Aware setting.

The problem is that if this feature is going haywire, it could easily cause my phone brightness keeps changing problem. To turn this off:
- Tap on Settings and navigate to Accessibility.
- There should be a setting for FACE ID and Attention.
- Tap on them and then change the toggle option next to Attention-Aware.
3 Disable the “True Tone” Option
It is a pretty new option that has helped iPhone users get a better experience on their devices by shifting the brightness setting according to the ambient light and temperature of their physical environment. It is a fun set to play with, but can get confused if you’re next to a fan or in a shifting outdoor area. The easiest solution is to turn this feature off when your iPhone brightness keeps changing unexpectedly.
- Go to Settings and tap on Display and Brightness.
- Under the brightness bar you’ll see the True Tone option.

The Low Power mode is designed to dim your screen whenever your battery reaches a low level, like 20% or 10% of the total battery charge. You can turn this off by:
- Go into Settings > Battery > Low Power.
- Slide the toggle next to that to the off position.
6 Extend How Quickly Your iPhone Auto-Lock
The auto-lock mode we mentioned earlier is a great feature for your iPhone. It helps you defend against unwanted users trying to see what is on your device when you have put your phone down for a little while and to focus on other things. If you feel like this mode is too short, you have the option to extend it longer than a few seconds. You can do this by:
- Go to Settings > Display and Brightness > Auto-Lock.
