In the speed test videos we get to see the iOS 11.2.5 Beta 4 vs iOS 11.2.2 tested side by side on the iPhone 5S, the iPhone 6, the iPhone 6S and iPhone 7. Will there be any improvement in speed, up first is the iPhone 5S.
As we can see from the video the iPhone 5S running iOS 11.2.5 beta 4 booted up slightly faster than the device running the current release. There does not appear to be much difference between the two in the apps, next up is the iPhone 6.
With the iPhone 6 the one running the iOS 11.2.2 software appeared to boot up slightly faster than the device running the new beta of iOS 11.2.5. The current release also appears to be slightly faster within the apps, next up is the iPhone 6S.
As we can see in the video the iPhone 6S running the iOS 11.2.2 software booted up faster than the handset running the iOS 11.2.5 beta 4, the two handsets seem about the same running apps. Finally we have the iPhone 7.
The iPhone 7 running the iOS 11.2.2 software also booted up slightly faster than the device running the latest beta. There is not much difference between the two when running the apps. So it would appear that the new iOS 11.2.5 software could bring some minor speed improvements to the iPhone 5S. This may change by the time the final version of iOS 11.2.5 is released later this month.
