iOS 12.4.7 Battery and Speed Test on iPhone 6 and iPhone 5S.

OS 12.4.7 was released by Apple May 20th for older devices, the same day Apple released iOS 13.5 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 12.4.7. 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.
