Hello everyone, and welcome to the iOS 15.1.1 battery performance video on iPhone 12 & 13.
Battery test for the iPhone 12&13 exclusive iOS release iOS 15.1.1
Note that both the iPhone 13 and 12 in this video are BRAND NEW DEVICES. With very
limited use on the channel so far, so they should have the best performing battery
at this stage in its life.
This video was shot 6 days iOS 15.1.1 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 6 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…
