Apple iPhone 6 years anniversary Watch all iPhone models go head to head in a test of speed

The first iPhone was launched back in 2007. Since then, Apple’s smartphone has continued to be a major player in the global smartphone arena. Tens of millions of units have been sold around the globe and sales don’t seem to be slowing down anytime soon, particularly due to the fact that the company just recently announced two new models. As of now, Apple has released eight models of the iPhone ever since the first one came out in 2007.

Obviously, a lot of hardware changes and advancements have been made. Its obvious that the original iPhone is going to be smoked by the iPhone 4, or even the iPhone 3GS. However, it is interesting to note that all iPhones running iOS 7 seem to power down simultaneously. In the test of speed, all iPhones are first shut down and then booted together. The iPhone 5s and iPhone 5 are neck and neck, with the iPhone 5c slightly trailing behind both of them.

Web tests are also conducted, which reveal just how much the browsing experience and speed has been improved over the years. In the web test, all iPhones are sent to Apple’s home page as well as Reddit. If you’re interested in seeing how things have changed for the iPhone in all these years, do take a look at the video posted above.
