Video Test: a comparison of the speed of the iPhone 4s on iOS 5 and iOS 9

Another test video, this time from the blogger iAppleBytes, who decided to empirically verify how different performance mobile platforms iOS 5.0.1 and iOS 9.0.2, running on the smartphone iPhone 4s.


Recall that the operating system iOS 5 was released in 2011, while iOS 9.0.2 was released in late September this year. As with all such tests on two identical models of the iPhone series the pre-installed software and fixed speed response platform.

Watching the progress of testing, you can see for themselves that the smartphone iPhone 4s, running iOS 5.0.1, almost all applications open faster than a similar gadget, but with the latest version of the firmware on the board.

In addition, it was stated that the slow work of iPhone 4s running iOS 9 is also due to the peculiarities of the interface platform - its specific "smooth" animations.
