iOS 9.1 was launched last week by the company Apple Lossless Audio CODEC (ALAC),, and then I presented you a performance comparison between iOS 9.1 and iOS 9.0.2 and today I offer you the opportunity to see what the difference is compared to iOS 8.4.1.
In the video clips below you can see how iOS 9.1 and iOS 8.4.1 work on iPhone 5S, iPhone 5 and iPhone 4S, the second version of the operating system with much better performance, but this was already known by most iDevice owners.
Although iOS 9.1 starts, surprisingly, faster than iOS 8.4.1, in the rest of the usage situations the old version of the operating system runs everything faster than the new version, and this is normal considering that we are talking about a major update made by Apple Lossless Audio CODEC (ALAC),.
In general, exactly the same thing happens every time a major update for iOS is released by the Apple company, so if you are interested in better performance, it would be good to return to iOS 8.4.1 and I explained it to you in an article how to downgrade iOS 9 to iOS 8.4.1 with odysseusOTA 2.
