Optimized Battery Charging not working on your iPhone
Optimized Battery Charging learns your charging routine and only works if it thinks you're charging overnight. If you charge at different times every day, the phone can't learn when to hold at 80 percent. Try keeping your phone plugged in at the same time every night for a week — once the pattern is clear, it will start working.
Optimized Battery Charging is designed to protect your battery by keeping it at 80 percent for as long as it can during overnight charging, then charging to 100 percent just before you wake up. But it only works if your iPhone can see a clear pattern — if you charge at random times, it can't predict when you'll need your phone and charges all the way to 100 percent to be safe. Charging at consistent times lets the phone learn your routine.

Skip — I just want a technicianCommon mistakes to avoid
- Thinking you need to charge at night — the feature is designed for overnight charging but can work any time if the pattern is consistent
- Giving up after a few days and switching the setting back off — the phone needs at least a week to learn your routine
- Assuming the feature is broken when it's actually just waiting to see a clear pattern
Signs you need professional help
- The setting is on and you've been charging at the same time every night for two weeks, but it still isn't activating
- The feature was working but suddenly stopped — there can be a system issue or the pattern changed too much
- You're seeing battery health drop rapidly even though Optimized Battery Charging is supposed to be on
