Optimize your settings.
There are two simple ways you can preserve battery life — no matter how you use your device: adjust your screen brightness and use Wi-Fi.
Dim the screen or turn on Auto-Brightness to extend battery life.
- To dim, swipe up from the bottom of any screen to open Control Center and drag the Brightness slider to the left.
- Auto-Brightness adjusts your screen to lighting conditions automatically. To activate it, go to Settings > Display & Brightness and set Auto-Brightness to On.
When you use your device to access data, a Wi-Fi connection uses less power than a cellular network — so keep Wi-Fi on at all times. There are two ways to turn on Wi-Fi:
- Swipe up to open Control Center, tap the Wi-Fi icon, and log in to a Wi-Fi network.
- Go to Settings > Wi-Fi to access a Wi-Fi network..
