YouTube channel EverythingApplePro posted an interesting video this weekend, showing multiple side by side speed comparison tests of all 10 iPhone models. This includes the iPhone 6 Plus, iPhone 6, iPhone 5s, iPhone 5c, iPhone 5, iPhone 4s, iPhone 4, iPhone 3GS, iPhone 3G and the original iPhone.
The clip, which is about 4 minutes long, shows a wide range of speed tests such as shutdown, startup, webpage loading, and even a GeekBench benchmark test. For the most part everything works out like you'd expect, with the newer devices outpacing their predecessors, but there are a few surprises.
