Once again, YouTube channel iApplyBytes has had the time and patience to compare the iOS 11.2.1 battery performance to that of its predecessor, iOS 11.2. The resulting video shows the results and sees if Apple has made any notable improvements where battery management is concerned with the release of iOS 11.2.1.
The process involved should be extremely familiar by now. Multiple iOS devices, which in this instance involves iPhone 5s, iPhone 6, iPhone 6s, and iPhone 7, are loaded up with iOS 11.2 and iOS 11.2.1 and ran through the new battery test on Geekbench 4.
That particular test is designed to obliterate the battery with power-hungry tests in order to consume its power as quickly as possible. We are then left with a timing score at the end which shows just how well each device running each tested version of iOS was able to perform. Where iOS 11.2 is concerned, which is the version of iOS that introduced Apple Pay Cash and 7.5W faster wireless charging, iPhone 5s was able to stay running for 2-hours and 18-minutes, iPhone 6 for 2-hours and 8-minutes, iPhone 6s for 2-hours 54-minutes and iPhone 7 for 2-hours and 41-minutes.
All fairly respectable results considering the test was designed to hammer the battery into oblivion and deplete it as quickly as possible. iOS 11.2.1, which is Apple’s latest public release, manages to squeeze just a few more minutes out of each device, with iPhone 5s lasting 2-hours and 24-minutes, iPhone 6 for 2-hours and 12-minutes, iPhone 6s for the same 2-hours and 54-minutes, and iPhone 7 for 2-hours and 43-minutes.
The improved times aren’t exactly mind-boggling, and definitely won’t give users endless hours of additional browsing or viewing time, but are definitely enough to show that noticeable improvements have been made where iOS 11.2.1 and power management are concerned. Of course, Apple now has iOS 11.2.5 in a pre-release state with registered developers and testers, with the second beta arriving only just now right before the Christmas shutdown, so it’s only a matter of time before we can tell if any additional improvements have been made.
Still, until then, check out the video for yourself below and see how the results of the video compare when pitted against your own experiences on iOS 11.2 and iOS 11.2.1.
