iOS 9.2 beta goes up against iOS 8.4.1 in new speed test


iOS 9.2 vs. iOS 8.4.1 speed test

66 percent of compatible devices have already been updated to iOS 9, according to Apple, but 25 percent are still clinging onto iOS 8 and earlier releases. It’s thought speed concerns may have something to do with that — but can the latest iOS 9.2 beta change that? Find out in the speed tests below.

iAppleBytes has put the iOS 9.2 beta up against iOS 8.4.1 — the most recent iOS 8 release — to establish which is fastest on the iPhone 4s, iPhone 5, and iPhone 5s. As these devices are getting older now, they’re the ones that will be most affected by any decreases in snappiness.

As you’ll see in the videos below, the iOS 9.2 beta boots up slightly faster than iOS 8.4.1 on the iPhone 5s, but iOS 8.4.1 boots up faster on the iPhone 5 and the iPhone 4s. However, when it comes to opening and switching between apps, there’s not a whole lot of difference into the two.

On the iPhone 5 and iPhone 5s, both iOS 8.4.1 and iOS 9.2 open and load apps at identical speeds. One is ever so slightly snappier than the other in some cases, but the difference is so small, it’s really not worth noting. Both also get very similar GeekBench scores; iOS 8.4.1 gets more points, but again, the difference is small.

On the iPhone 4s, it’s a different story. There’s noticeable lag with almost everything in iOS 9.2, whether it’s loading apps, opening messages, using the keyboard, and even just unlocking the device. The difference isn’t too great, but it’s certainly noticeable.

If you’re still using iOS 8 for fear that upgrading to iOS 9 will make your iPhone slower, then, you can be sure that the difference is pretty negligible on the iPhone 5 and iPhone 5s. However, if you have an iPhone 4s, perhaps you’ll want to stick with the older software if you value performance.
