Apple released iOS 12.1.1 software update recently, we have already seen some speed test videos of the OS and now we have a battery test video.
In the video below we get to see the new iOS 12.1.1 and the previous iOS 12.1 software to see if there are any battery life improvements.
As we can see in the video the iPhone 5S had a slightly lower battery life on the new software as did the iPhone 7. The rest of the handsets has slightly longer battery life.
The battery life improvements on the new iOS 12.1.1 software are minimal so it looks like this new OS has brought no major difference in battery life to Apple’s iPhones.
