For users who have been experienced performance degradation after updating an iPhone or iPad to iOS 9 from iOS 8.4.1 or older, you may be pleased to discover improved performance on some devices with the iOS 9.2 update.
The speed boost offered with iOS 9.2 is particularly noticeable with the iPhone 6 Plus, which many users discovered had significant lag and interface stuttering after updating to iOS 9 with even the most basic of tasks, like bringing about Spotlight search or opening the Camera. Additionally, the user interface lag and stuttering seems to have been improved on that device quite a bit as well, and while it doesn’t feel as fast as iOS 8 did on the same hardware, it does seem to offer a noticeable improvement over any of the prior iOS 9.x releases. Apparently some other models also have received a slight performance increase from the device as well, but they may not be as notable as that which is experienced on the iPhone 6 Plus, nonetheless users should probably update to the latest version and discover how the performance is on iPhone 6, iPhone 5S, iPhone 5, iPhone 4s, iPad Air of all models, and all supported iPad Mini devices.
From personal experience, the iOS 9.2 update initially didn’t seem to help the speed of my own frustratingly laggy iPhone 6 Plus with iOS 9.1, but after hard rebooting the device hours later, it was suddenly much faster and the UI lag and stuttering was much improved. No more half second lag to bring up the keyboard in Spotlight search, no more 10 second delay to open the Camera and start using it, apps open faster, the multitasking screen to quit apps is faster, the device just feels much faster, and it’s notable. Sure this is anecdotal evidence and it applies to the iPhone 6 Plus, but a quick search on Twitter, our comments, and Apple Support Forums has shown that many other users have experienced similar performance improvements with iOS 9.2 after a second reboot on other devices too.
The iOS 9.2 Speed Boost Trick: Update, Wait, and Reboot
Again this is mostly relevant to iPhone 6 Plus but it may apply to other devices as well, let us know in the comments what your experience has been.
- Back up the iPhone first (this keeps your stuff, but also allows you to downgrade back to iOS 9.1, for a limited time anyway, if you want to for some reason)
- Update the iPhone or iPad to iOS 9.2 and let the installation complete and return back to the Home Screen
- Let the device sit and do nothing for an hour or two, this is recommended as under the hood tasks are taking place to index the device. Some initial perceptions of reduced speed due to iOS updates are simply the maintenance routines going on in the background, so let this complete
- After the iPhone or iPad has been updated and sat for a while, do a force hard reboot by holding down the Power button and Home button, let the device boot as usual and enjoy your (hopefully) freshly snappier iOS experience
If you update to iOS 9.2, wait a few hours, hard reboot, and still experience sluggish performance, you may want to try some of these direct performance improvement tips for iOS 9 devices, which involve disabling some features to lighten the software load on hardware a bit.
While the release notes of iOS 9.2 don’t mention much of anything about performance enhancements included in the update, it’s quite possible some under the hood improvements were made. Whatever the reason, iOS 9.2 seems to run faster than iOS 9.1 or iOS 9 did on the same hardware, and a variety of videos help to demonstrate this:
Note some of these performance videos were made with earlier beta releases so they are less reliable, but the topmost video is an iPhone 6 Plus with iOS 9.2 final.
What have you noticed? Have you experienced any performance changes with iOS 9.2? Maybe speed improvements with iOS 9.2? Let us know in the comments. And hopefully you have not found iOS 9.2 leads to slower hardware, but if you’ve experience declines in performance, let us know that in the comments too.
