Apple rolled out a surprise iOS 9.3.4 update on Thursday, which promises to improve security on iPhones and iPads. But does it make them any faster? Find out in the speed test videos below, which compare iOS 9.3.4 with iOS 9.3.3 on the iPhone.
iOS 9.3.4 is only a minor software update, weighing in at just 25.1MB if your device is already running iOS 9.3.3. You’re probably thinking it’s not going to make any difference to performance, then — but you’re wrong.
iOS 9.3.4 actually makes the boot up process ever so slightly slower on the iPhone 6s. There’s certainly not much in it, but it’s definitely a noticeable difference. Performance throughout the rest of the OS remains almost identical.
Strangely, iOS 9.3.4 actually boots slightly faster than iOS 9.3.3 on the iPhone 6, iPhone 5s, and iPhone 5. However, just like on the iPhone 6s, the experience when launching apps, loading webpages, and multitasking it almost unchanged.
iOS 9.3.4 makes no noticeable change to boot-up times on the iPhone 4s, however, it does appear to slow many other things down. Apps like Messages and Safari just aren’t quite s snappy after the update, though many others remain the same.
There’s no good reason to avoid iOS 9.3.4 if you use stock Apple software, then. Aside from the slightly slower boot-up times on the iPhone 6s and slight slowdowns on the iPhone 4s, it appears to be somewhat snapper on other devices.
Having said that, iOS 9.3.4 should be avoided if you jailbreak. The update patches the flaw that is used by the latest Pangu jailbreak, meaning once you have updated, there’s no way to get your hands on Cydia and all your favorite tweaks.
