iOS 15.2 Battery Life Drain And Performance Tested Across 9 Different iPhone Models [Video]

After a lengthy beta program, Apple has now made iOS 15.2 publicly available and, as always, people are concerned about what the update will mean in terms of battery life. Now we can answer that question.

Thanks to a video from YouTuber iAppleBytes, we can see what iOS 15.2 does with battery performance on various iPhones, nine of them to be exact.

Running the battery benchmarks, the video shows us that the results run on everything from an iPhone SE to an iPhone 13, with all kinds of devices in between. How did things turn out? You can watch the video to find out!

This video was shot 3 days ago after iOS 15.2 was installed so it had some time to adjust. I’ve seen a lot of feedback that it takes about a week to optimize battery performance after an iOS update. I have always been skeptical of this claim, as I have personally never experienced bad battery life right after the update. If I restore and download iCloud backup fine, then that’s another story. So I decided to run the battery test 6 days after updating them. In those 6 days they were simply inactive with the power connected. So let’s run the battery test again and see if we get a few different results this time.

The short version is that the iOS 15.2 update doesn’t seem to be great in terms of battery life, at least when using benchmarks. This may be a bug with Geekbench 4 rather than something indicative of a problem, but we’ll need more people to spend real time with the update to be sure.

Do these results match your experience with iOS 15.2? Let us know in the comments!
