But even in this situation, many users believe Apple failed to reach speeds of older versions of iOS. Is it really so? Let’s find out.

The comparison was conducted by channel iAppleBytes. For testing we used a few iPhone 5s — iOS 9.3.5, iOS 10.3.3 and iOS 12.1.3, respectively. The results were quite entertaining.
