While the iPhone has made some impressive strides when it comes to battery life, there are still some options that you can change which will help to extend life between charges.
One of the biggest contributors to battery usage is the screen brightness. The dimmer your screen is, the less battery it uses.
But changing the brightness of the screen while making it bright enough to read can be a delicate balance, and you might find that the screen is too dark.
You can change the iPhone 13 screen brightness by going to Settings > Display & Brightness > then changing the setting on the Brightness scale.
Our tutorial below provides additional information on locating and adjusting this setting, as well as an alternate way to change the brightness and some other brightness-related settings that you may want to change, too.

More Information on iPhone Screen Brightness
The steps above show you how to adjust the brightness of your iPhone screen by going through the Settings menu. However, you can also change the brightness from the Control Center.
To change iPhone screen brightness from the Control Center, swipe down from the top-right corner of the screen to open the Control Center. You can then drag the brightness scale up or down to adjust the brightness.
Note that if you tap and hold on the brightness icon in the Control Center, it will expand the scale while also displaying these options at the bottom of the screen:
- Dark Mode – this changes your iPhone’s color palette to a darker one so that the screen isn’t so bright in dark environments.
- Night Shift – this automatically shifts the colors on the screen to warmer colors which may help you sleep better at night.
- True Tone – this automatically adjusts the color tone of the device screen so that the appearance of the colors on the screen remains consistent with variable ambient light.
There is also an Auto-Brightness option on the Settings > Accessibility > Display & Text Size menu. If you have manually adjusted the brightness and find that it’s still too dark sometimes, turning off auto-brightness could help resolve that. Note that disabling auto-brightness can affect your battery life and the long-term performance of the screen.
