Tests Show Why You Shouldn’t Update Your iPhone 4S to iOS 8.0

Today Apple rolled out the first public version of it’s latest mobile operating system: iOS 8. It brings changes all-round whilst keeping the standard look of iOS 7. Though there are no mind-blowing improvements, there are general improvements all round including the ability to customize keyboards and a smarter Siri virtual assistant.

Apple have decided not to bring the update to the iPhone 4 – but 4S users are in luck; or are they? iOS 8 updates are available for iPhone 4S owners worldwide, but according to some very simple tests we carried out, we wouldn’t recommend updating!

Every year questions are raised as to why Apple decide to leave the oldest devices behind with new firmware updates. Apple claim that they try their best to bring updates to all users but the hardware of devices older than four years is simply not capable of handling the latest mobile OS.

The iOS 8 update seems focused on higher-end devices and does not respect the hardware of the iPhone 4S. We carried out several simple everyday tests and found the iPhone 4S to be slower in everything compared to an equivalent running iOS 7.1.2.

Applications iOS 7.1.2 iOS 8.0
Safari 1.25 seconds 2.16 seconds
Camera 1.5 seconds 1.8 seconds
Settings 0.95 seconds 1.25 seconds
Mail 0.91 seconds 1.30 seconds
Messages 1.73 seconds 1.83 seconds
Calender 0.8 seconds 1.25 seconds
Cold Boot 36.4 seconds 39.8 seconds

The table above shows how long it took for core applications to load up in iOS 7.1.2 and iOS 8.0 respectively. From these basic tests it is clear to see that iOS 8.0 slows down tasks on the iPhone 4S.

It seems that iOS 8 has been primarily aimed and tuned for the new flagship iPhone 6, and we can only hope iOS 8.1 will bring improvements for lower-end devices such as the iPad 2 and iPhone 4S.
