Apple released iOS 13.6 to the public recently but alongside that we also saw the arrival of iOS 12.4.8. Specifically released for devices that couldn’t run iOS 13, that update brought the usual array of security and bug fixes. But what did it do to performance and battery life?

That’s something that YouTuber iAppleBytes wanted to find out and the result is a speed and performance test video that runs for new fewer than 23 minutes. That’s what you call thorough.

iOS 12.4.8 was released by Apple July 15th for older devices, the same day Apple released iOS 13.6 to all new devices. Not of lot of info from Apple as to what is new in this release, but we must assume that it contains security fixes, bug fixes etc. You can even still jailbreak iOS 12.4.8. So there are not real reason why you should not upgrade from any other version of iOS 12. I will run a comparison anyways to see if there are any signs of performance improvements, just the same. I will also include a side by side battery test video of the iPhone 6 as those devices have new batteries.

The fact that this update was specifically designed for older iPhones means there’s more at stake here. Those older iPhones already have older batteries and slower chips inside – impact from a poor software update could be catastrophic.

We’re not going to spoil the fun of watching the video for you, but we will simply say this – we’d suggest watching it before you update. Just in case.
