iOS 11.2.1 Battery Life Test : Has it improved vs iOS 11.2? HD

So iOS 11.2.1 is out, and many wonder... Will it ruin my already great battery life, or will it improve my battery life which is horrible on iOS 11.2. In this test I try to figure that out by comparing iOS 11.2 vs iOS 11.2.1 in battery life using the battery life test of Geekbench 4. First I run the test on iOS 11.2, then upgrade to iOS 11.2.1 and run the full test once more, and then we compare the scores. The battery wear of the iPhones are measured in the beginning of the video and checked again before running again on the upgraded version. The iPhone 6S are on TMSC chipset. Hope you enjoy the video.
