Want to make that charge on your iPhone last a little longer? We’ve got a few tips.
First, consider switching to WiFi instead of using your phone provider’s 4 or 5G network. That’s less work your phone. Of course, that’s only if you’re somewhere you know you have a secure Wi-Fi Connection.
To turn on Wi‑Fi, go to Settings > Wi‑Fi to access a Wi‑Fi network.

Dim the Screen. Turning down the brightness level on your screen is another easy way to save power.
To manually dim your phone, open Control Center and drag the Brightness slider to the bottom.

Or go to Settings > Accessibility. Tap Display & Text Size, then turn on Auto-Brightness to allow your phone to automatically adjust.
Turn on Low Power Mode – Go to Settings > Battery – then switch on Low Power Mode. It will turn down the display brightness, minimize animations, and prevent apps from downloading content in the background. You will still be able to receive calls and messages.

Turn off Location Services – tracking your location can eat up a lot of power. Here’s how to turn it off – Go to Settings > Privacy > Location Services.
