Great iAppleBytes posted a video which compares the performance of the iPhone on which you installed two versions of iOS 9.1 and 9.2 beta 2. The purpose of the video: to compare the performance of operating systems.
As it turned out, iOS 9.2 speeds up the work “Apple” devices. Especially the effect is seen on older models – iPhone 4s and iPhone 5. In particular, you can see that the gadget with iOS 9.2 beta 2 runs faster, and the regular opening apps takes less time. The relatively new iPhone 5s, the difference in performance is not as noticeable. Probably in a new release Apple has decided to optimize the operating system for older devices.
The second experimental iOS release 9.2 was proposed by the company this week. In addition to correcting errors in the work of “smart” clock Apple Watch cloud and iCloud keychain, improved Safari the behavior of the View Controller, the “engine” of the Safari browser inside the app, which is now eliminated with a swipe.
The real novelty is the support function NumberSync that allows you to receive calls and initiate them from any approved device over the Internet. Now the Continuity feature allows you to use Mac, iPad, or iPod touch for calls, if the user’s device is connected to the same wireless network Wi-Fi. In this case we are talking about Wi-Fi calls that do not require being in network with the iPhone could be at least a hundred miles away and even out of network coverage.
