Speed Test Shows iOS 10.3 Starts 6 Seconds Faster on iPhone 5s

· · Cool Stuff Found

iAppleBytes did some speed tests comparing iOS 10.2.1 and iOS 10.3—with its new file system. In the video below, they show startup times on an iPhone 5 and an iPhone 5s. The device on the left of each pair is running iOS 10.2.1, the current shipping version of iOS. The devices on the right of each pair are running iOS 10.3, which includes Apple File System (APFS). This is a brand new file system years in the making, and it will change of underlying structural aspects of iOS. This demonstration shows one of those things is startup times. The iPhone 5s running iOS 10.3 started up 5.88 seconds faster than its cousin running 10.2.1. That’s 19.7% faster! The iPhone 5 running iOS 10.3 started up 7.57 seconds faster (18.7% faster). This is just one metric, mind you, and it’s important to remember this version of iOS 10.3 is the first developer preview. Newer iPhone and iPads with newer processors will likely show a smaller delta in absolute terms, but the whole point is that things are going to be happening faster. Squuuueeeeeeeeeeeeee!
