Particularly for those of us who have always used iPhones, it’s fascinating to be reminded of how far the technology has come in under a decade.

With that in mind, a recent video by YouTube channel EveryApplePro puts every iPhone model Apple has ever put out (with the exception, unfortunately, of the new iPhone SE) through a battery of tests to check everything from startup time to speaker output to, yes, even their heat signatures.

Check it out below.

If you can’t view it, the video tests how long it takes each iPhone to start up, their Geekbench processor stats, WiFi speeds, HTML5 and browser experience, how long it takes to load a website and open the camera app, the speaker volume, how hot the iPhones run, and a side-by-side look at their image quality. Most of the results are as you would expect them — with the newer iPhones triumphing over their predecessors.

There were a few interesting take-homes, however. The first is just how much better the iPhone 6s generation is compared to those handsets which have come before. We take it for granted that Apple puts out a superior phone each year, but it’s still astonishing to see how the company has managed to improve on literally every aspect of the device over the years. The difference in photo quality is particularly striking.

The second is the fact that newer iPhones run hotter than their predecessors — with the hottest point of the iPhone 6s being 106.7 degrees after ten minutes of heavy usage, compared with just 85.4 degrees for the original 2007-era iPhone: likely down to the size of the battery and the amount of pixels they have to push around on-screen.

Finally it’s interesting to be reminded that, for iPhone 4s users, upgrading to iOS 9 (the oldest iPhone capable of running Apple’s latest mobile OS) is a big mistake. That won’t come as a shock to anyone who has tried using iOS 9 on an older iPhone, but it’s starkly obvious when you watch a battery of tests like this one.
