Extended Information: Tips to Extend iPhone Battery Life:

1.Make it a good habit to recharge.

Charge the battery in time when the iPhone prompts a low battery to avoid automatic shutdown caused by too low a battery, and try to replace the battery if the battery efficiency is less than 80%.

2.Turn on Optimized Charging.

This function can intelligently learn and judge the user's usage and charging habits, so that the charging process is more balanced, thereby slowing down the aging of the battery and improving the battery life of the iPhone to a certain extent.

How to view: The "Optimize Battery Charging" function can be viewed in Settings - Battery - Battery Health

3.Disable background app refreshes.

Apps use battery life when running in the background. You can see how much time the app is running in the background. If an app runs out of too much power when it's not in use, you can disable background app refresh to prevent it from running in the background.

If the app is draining too much battery, we can also choose to uninstall it!

4.Enable the Low Power Mode.

The "Low Power Mode" feature allows your phone to save more battery. When Low Power Mode is enabled, your screen dims slightly, restricting background processes, slowing down your processor slightly, or reducing the amount of energy your device needs during normal use.

How to do it: The easiest way to enable this feature is to swipe down from the top right corner of your iPhone and then the battery icon. Or you can enable the low power mode in Settings > Battery > Low Power Mode.

Push app notifications, email-read notifications, and more can all shorten battery life, so it's best to turn it off to make your iPhone last longer. Notifications can be turned off in "Settings" for each app.
