iOS 16.7 Battery Life / Battery Drain / Speed Test.
iOS 16.7 was released September 22, 2023. It came with a different build number that the RC release.
This video was shot more than 48 hours after iOS 16.7 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 more than 48 hours after I updated them this time. In that period they were left without power and then powered back to 100% to be
ready for the test to run.
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.
