iOS 12 in the beta version is already faster than iOS 11
The first beta version of iOS 12 is out and there are already the first comparison tests with iOS 11. iOS 12 actually brings a small speed advantage.
No matter on which iPhone you install iOS 12 Beta, it actually always seems to be a little faster than the current version. Even the iPhone 5s is still very usable. This is good news, of course, because more speed is always welcome. This acceleration may even increase if iOS 12 is properly mature by the time it is released.
