iOS 13.5.1 Battery Life / Battery Performance Test.
the iOS 13.5.1 battery performance video. This video was shot 6 days after iOS 13.5.1 was installed, so it had time o settle in, so to speak. I have seen many comments that it takes about a week for battery performance to optimize it self after an iOS update. I have always been skeptical on this statement as I have never personally had bad battery life right after I update. If I restore and download backup from iCloud well then that is another story. So I decided to run the battery test 6 days after I updated them. In those 6 days they were just idling with power connected. So let us run the battery test again, and see if we will get some different results this time around.
