IOS 9.2.1 make iPhone 4S faster (Video)

iPhone 4S is faster with iOS 9.2.1 than with iOS 9.2, and that we're seeing thanks to a performance test that I've presented today in him being compared iOS 9.2 with iOS  9.2.1 public beta 2 released a few days ago by the Apple company.

As you'll see in the video below, iPhone 4S with iOS 9.2.1 beta 2 public works much better than iPhone 4S with iOS 9.2 and this is quite surprising considering that so far Apple has not improved terminal performance significantly with iOS 9.

Depending on what you do with iPhone 4S in iOS 9.2.1 public beta 2, you will sense the difference even a few seconds of iOS 9.2 and this says a lot about how Apple engineers were able to improve the performance of a terminal for more than 4 years old.

Since iOS 9.2.1 public beta 2 is a beta version of an update for iOS 9, you don't need to be 100% sure that you will have exactly the same performance when iOS 9.2.1 will be officially released, Apple can make changes that cancels this raise performance.
