I am enable the optimised battery charging but like it’s show it’s not working in battery level when I change my iPhone overnight . It seems like it’s fully charged 100 in one half hour . My problem is where the battery optimised work

Please review your first screen shot. Under Optimized Battery Charing, it states that, To reduce battery ageing, iPhone learns from your daily charging routine so it can wait to finish charging past 80% until vou need to use it.

Your iPhone will learn from your charging patterns over time and then determine how long and when to get your iPhone charged to 100%. Sometimes it takes weeks for the iPhone to learn your charging patterns.
