Boot Speed Test: iPhone 5s vs iPhone 5c vs iPhone 5
As I’ve mentioned before, the iPhone 5s with a brand new 64-bit processor was the fastest. It took only 20.5 seconds for it to boot. The boot speed of the iPhone 5c and iPhone 5 is 25.9 and 29.0 seconds respectively. You should note though, that the devices were restored to iOS 7 before the testing and contained no user data. So the actual boot speed may vary.
Here’s the boot speed ‘competition’ video.
