Earlier today, Apple released iOS 9.2.1 for the masses. Are you waiting to update your iOS device? Those with older devices, such as the iPhone 4S, can be wary of new firmware updates, as in the past they have slowed things down.

YouTube channel EverythingApplePro has shared a speed test comparison of iOS 9.2.1 vs iOS 9.2 on the iPhone 4S, iPhone 5/5S and iPhone 6/6S. A variety of hands-on tests of animations, boot-up speeds, app loading speeds, Wi-Fi and Geekbench scores and more are compared.

Check it out below:

Have you updated to iOS 9.2.1 yet? How did it go?


  • I did the whole “About phone” sliding back a forth as he does in the video, and yeah it’s ever so slightly choppy, but I never did that test on my 6s Plus before I updated, so I’m not sure if that’s from the update, or has always been like that

    As for everything else, I don’t see any difference. My 6s plus performes exceptionally well as it always has.

    This post would have been much more helpful to *readers* had you given a summary of the results rather than making them commit to watching a 6 minute video to get an answer.

    He’s talking fractions of a second and this is definitely not a scientific analysis. Most people wouldn’t notice any difference on one vs the other.
