Manage Your iPhone’s Brightness
The iPhone 13’s display is one of the best on the market. With that said, the larger and more powerful the display is, the more battery power it needs. You can help this by reducing the screen brightness on your iPhone from the Control Center. Another thing you can do is disable True Tone. That way, your iPhone won’t constantly be adjusting the screen brightness and color based on your environment.
- Go to the Settings app.
- Scroll down and tap Display & Brightness.
- Toggle True Tone off.
You can also do it from your Control Center by long-pressing the brightness slider and tapping True Tone at the bottom right corner.
Tip: If you’re using the iPhone 13 Pro or 13 Pro Max, you might also want to consider disabling ProMotion. You can do this by going to Settings > Accessibility > Motion and then just tap the toggle next to Limit Time Frame.
