Anyone using Optimized Battery Charging ? I have it on from day 1 by default. And according to apple, there should be a notification appearing once u hit 80% charging, so it won't go beyond 80%, but every single time it goes beyond 80%, like to 82%, and no notifications. I also read that in Location Services > System Customization MUST be enabled, and also Significant Location, but almost everyone said that Significant Location must be turn off to extend battery life as it's continuously using GPS to check your location, but System Customization is the one that must be enabled for OBC to work, can anyone verify ?

For the record, I don't charge my phone overnight, I normally always charge it any time of the day most likely around night time, I charge it at 40-50% and manually unplug it when it reaches 80%, but sometimes I forget and it goes beyond 80%, does this means OBC will not work for my situation ?

Your iPhone uses on-device machine learning to learn your daily charging routine so that Optimized Battery Charging activates only when your iPhone predicts it will be connected to a charger for an extended period of time.

So in order to meet that condition, I have to charge my phone at almost the same time daily or I have to charge my phone overnight daily ?

Ohh i see, so for my case, if I charge it manually even at the same exact time, for less than 1-2 hours, OBC will never activate ? And to have it activate the only option is to charge it overnight..
