Tips to extend iPhone battery life:
1. Develop a good habit of charging
Charge your Apple cell phone in time when it prompts a low battery, to avoid the low power caused by automatic shutdown, if the battery efficiency is less than 80% try to replace the battery.
2. Turn on Optimized Charging
This feature intelligently learns and judges the user's usage and charging habits to make the charging process more balanced, thus slowing down the aging of the battery and boosting the iPhone's battery life to a certain extent.
How to check: The "Optimize Battery Charging" feature can be found in Settings - Battery - Battery Health~
3. Disable background app refreshes
Apps use battery life while running in the background. You can see how much time apps are running in the background. If an app is draining too much power when you're not using it, you can disable background app refresh to prevent it from running in the background. We also have the option to uninstall apps if they're draining too much power!
4. Enable Low Power Mode
The Low Power Mode feature allows your phone to save more power. When Low Power Mode is enabled, your screen dims slightly, restricts background processes, slows down the processor slightly, or reduces the amount of power your device requires 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 low power mode in Settings > Battery > Low Power Mode.
5. Turn off certain app push
Push app notifications, email read notifications, etc. can shorten battery life, so it's a good idea to turn them off to make your iPhone battery last longer. You can turn off notifications by editing each app in Settings.
