If you don’t like Optimized Battery Charging feature, or are charging your phone outside of your usual routine, you can go the manual route. As we mentioned above, one of the best things you can do to increase your iPhone’s overall battery longevity (reduce degradation) is to not charge it over 80%.
Now, there’s no reliable way to actually force iPhone to stop charging after 80%, but using a Shortcuts automation, you can get an alert when the iPhone is charged over 80%. Then, you can simply yank out the charging cable. Gently, of course.
Open the Shortcuts app, go to the “Automation” tab, hit the Plus button, and choose “Create Personal Automation.”Go to “Battery Level,” configure the setting to “Rises Above 80%,” and tap the “Next” button.Search and add the “Speak Text” action. Change the command to something like “Charged Up,” and tap the “Next” button.Disable the “Ask Before Running” option, and tap the “Done” button.Now, when your iPhone charges past 80%, you’ll hear an audible cue to remind you to unplug it.
