How to Fix it When Optimized Battery Charging is Not Working on iPhone 13

Optimized battery charging is designed to keep your iPhone 13's battery lasting longer. This smarter charging keeps track of how you use your iPhone and only charges it fully when it knows you'll need it.

Why Is My Optimized Charging Not Working?

Your iPhone 13 has enabled optimized battery charging, but it may have been accidentally turned off. This feature also requires a consistent charging routine to activate and function properly.

Another place to look is your iPhone’s location services settings. Optimized battery charging requires specific permissions to work, including:

• General location services
• System customization permission
• Significant locations access
  

Last but never least, your iPhone might require a reboot or a system update to keep this feature working.

How to Fix Optimized Charging On iPhone 13

Try this list of solutions in order, from simple to more time-intensive. Unless something very unusual is wrong, one of these will get you fixed up.

1. Check you have the feature on. While your iPhone 13 most likely shipped with optimized charging on, double-check this feature is active. Tap Settings > Battery > Battery Health > Optimized Battery Charging and ensure the toggle is green.
   

   

2. Turn the feature off and on again. A tried-and-true fix for malfunctioning features is to give them a reset by turning them off and on again. Select Settings > Battery > Battery Health > Optimized Battery Charging and move the toggle from green to gray and back on to see if that helps.
   

3. Turn on location services. Go to Settings > Privacy > Location Services, and ensure the toggle is in the on position. The optimized charging tool won’t work unless you activate location services generally, as well as the following permissions:

   • System Services > System Customization
   • System Services > Significant Locations 
     

4. Reboot your iPhone 13. This step often resolves issues by clearing the phone’s cache and memory. Try this fix after double-checking you’ve turned on optimized battery charging or disabled and enabled the feature, and all required location permissions are on.
   

5. Update iOS. Now would be a good time to check your phone isn’t due for a system update. Visit Settings > General > Software Update.
   

6. Keep a consistent charging routine. Optimized battery charging works well only if you maintain a consistent schedule, such as charging your battery overnight or at the same time every day. The tool also only works at home or what Apple calls significant locations, which you often visit, so the feature might not work while traveling or when varying your schedule a lot.
   

7. Give the feature time to learn. The optimized battery charging feature uses machine learning to monitor your battery performance needs. However, your iPhone 13 could require more than a few days to know your charging habits.
   

8. Factory reset your iPhone 13. If you don’t have any luck with the above steps, reset your device to its factory settings and try again with a clean slate. Tap Settings > General > Transfer or Reset iPhone > Erase All Content and Settings and follow the instructions. 
   

   As the setting says, this deletes all your content. Make sure you have backups.

9. Contact Apple Support. If you’ve waited a considerable amount of time and all your settings are correct, you might want to seek support from Apple about what could be causing issues with optimized battery charging on your iPhone 13.
   

   Another way to make the most of the iPhone 13’s long battery life is to turn on Smart Data mode if you use 5G.
