Apple gives you the freedom to adjust your iPhone's screen brightness, so you can set it as high or as low as you want. Although many people set their screen brightness somewhere in the middle, the brighter your screen shines, the faster your battery will drain.
The iPhone's Auto-Brightness setting also does a decent job of adjusting brightness based on the ambient light around you, but if you're willing to set the level lower, you can save more juice. Here's how to adjust your screen brightness manually to save crucial battery life.
- Navigate to the Settings menu, then tap Brightness & Wallpaper.
As you move from environment to environment, you may find it necessary to adjust the brightness manually. For example, if you're in direct sunlight, you'll need to pump it up to maximum, but if you're in a dark place, you may be able to get by with the lowest setting.
