The release of the iOS 9.3.4 a week ago came as a surprise, because everyone thought that iOS 9.3.3 will be the last update before the arrival of iOS 10. This new update was released without being previously announced and it is supposed to be a security update for iPhone and iPad. Is it worth installing it? Does it improve the performance of Apple’s devices?
First of all, iOS 9.3.4 can be installed on the iPhone 4S (or later), iPad 2 (or later), iPad mini (or later), iPad Pro tablets and the 5th generation iPod touch (or later) and if users don’t receive the notification to upgrade, they can manually trigger it by going to Settings > General > Software Update. The installation file weighs in between 20MB and 80MB, which means that you won’t have to connect to a wireless network to download it. So, should you upgrade from iOS 9.3.3 to iOS 9.3.4? A guy wanted to see if there’s any difference between the two updates in terms of performance and he installed them on a iPhone 4s (32GB), iPhone 5 and 5s (64GB), and iPhone 6 and 6s (16GB).
In the cold boot test, iOS 9.3.4 and iOS 9.3.3 had identical boot times on the iPone 4S, but on the iPhone 5 and iPhone 5S, the iOS 9.3.4 booted up faster. It’s interesting that iPhone 6 booted faster with iOS 9.3.4, while iOS 9.3.3 booted up faster on the iPhone 6s.
When it comes to the boot times results when launching some applications, it seems that iOS 9.3.4 was a few milliseconds faster, but when it came to memory, the previous iOS 9.3.3 caught up quickly.
iAppleBytes has ran a few tests on the iPhone 4s, iPhone 5/5s, and iPhone 6/6s and posted videos with the results for each device running on the two operating systems.
