This week Apple released an update iOS 9.2.1 beta 1 and made it available for everyone to test the new release of the mobile operating system. Not only developers, but ordinary iPhone and iPad users can download and install a test build of iOS 9.2.1. iAppleBytes decided to compare the performance of iOS updates 9.2.1 and previous major release of IOS, iOS 9.2.
9.2.1 iOS public beta became available after the closed test developers, which had begun the day before. She did not find any significant changes at the function level, which suggests that the update focuses on fixing bugs, improving performance and other improvements.
Performance iOS and iOS 9.2 9.2.1 compared three relatively older devices – iPhone 4s, iPhone 5 and iPhone 5s. From what you can see in the video, the updated OS works a bit faster in some aspects. The smoothness of the interface is improved, and the startup speed of applications slightly increased. It remains to wait for the final version of iOS 9.2.1, to confirm the preliminary test results.
