Hello everyone, and welcome to the iOS 15.6 battery performance video.
iOS 15.6 was released on July 21st, 2022.
This video was shot 2 days iOS 15.6 was installed, so it had some time to settle in. I have seen many comments that it takes about a week for battery performance to optimize itself after an iOS update. I have always been skeptical of 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 2 days they were just idling with power connected. So let’s run the battery test again, and see if we will get some different results this time around.
Before the test was run the devices were set to 25% display brightness, auto brightness has been disabled, all devices use same settings, and are connected to the same access point.
