iOS 12 Home screen With Downtime Enabled 1

Apple is all set to release iOS 12 in a few hours from now. The company boasts that the latest version of the OS brings about major performance improvements especially for its older devices. But what about battery life? Does iOS 12 bring about any improvements in the battery life department as well?

As an iOS 12 Golden Master vs iOS 11.4.1 battery life test conducted by YouTuber¬†iAppleBytes¬†shows, the performance improvements in iOS 12 actually come at the expense of battery life. For the test, the YouTuber used Geekbench’s battery life benchmark and ran it on the iPhone 5s, iPhone 6, iPhone 6s and iPhone 7. All four phones had fairly new batteries with minimal wear and tear, and the testing conditions while running the tests across different operating systems were the same.

The iPhone 7 saw its battery runtime score decrease to 2 hours 53 minutes on iOS 12 when compared to 3 hours and 11 minutes it managed under iOS 11. Similarly, the iPhone 6s saw its battery runtime reduce to 2 hours 42 minutes on iOS 12 when compared to 2 hours 54 minutes on iOS 11. The iPhone 6 was the worst hit as its battery life declined to 2 hours 36 minutes under iOS 12 vs 3 hours on iOS 11.4.1. Lastly, the iPhone 5s managed a battery runtime of 2 hours 42 minutes under iOS 12, while under iOS 11, its battery runtime score was 2hours 58 minutes.

iOS 12 Battery Life

Overall, it looks like the performance improvements in iOS 12 come at the cost of slightly lower battery life. Nonetheless, it is also possible that Apple will be able to further tweak and optimize the OS with future point releases to reduce this difference in battery life.

Are you disappointed that iOS 12 does not bring any improvements in the battery life department as well? Or are you just happy with the performance improvements it is going to bring to the table?
