iphone 11 not charging to 100% since updating to ios18
Since updating to iOS 18 4 days ago, my iPhone will not charge to 100%. I wake every morning and it’s at 76%.
iPhone 11, iOS 18
Try a Forced Restart on the phone. Follow the instructions very carefully, as this is a bit tricky. (Hint.....ignore the "slider" when it appears and keep holding the Side button in until the Apple logo appears. This might take another 30 seconds.)

Enable Optimized Battery Charging and connect the power supply to the phone at night and leave it connected all night....every night.
It may take up to 2 weeks for Optimized Battery Charging to learn your routine.
