For a full charge in the morning, it only takes half hour of reading news for the battery drop from 100% to 93%.Lastly, there’s Low Power mode, which disables things like the always-on display and limits the display refresh rate to 60Hz on ProMotion devices to save battery power for essential tasks.

Jul 4, 2020. #1. Hi!. I have a problem with my iPhone 11 Pro Max. My iphone has 100% battery condition on the iOS 13.3.1 software and I noticed that when the phone is charged to these 20-40%, the battery often drops by 2%, i.e. the phone lies a few minutes at 30% and usually drops after one or at all. A 4 minutes later it can drop to these 28%9ypM.
