Apple has released a total of eight iPhone handsets since 2007 and each one has been released with the promise of faster speeds and improved performance.
But how different is the original model to the current 5S?
Fan site EverythingApplePro has created a video test of all eight handsets, from the original to the new model, plus the 3G, 3GS, 4, 4S, 5 and 5C.
Each of the handsets were ‘freshly restored and not jailbroken’ meaning they each had the same default settings and all applications were force closed beforehand.
In the first test, all the phones were powered off simultaneously and the 3GS shut down fastest, followed by 3G, then the 4, then the original model.
The newer handsets all took noticeably longer than the older models, but took exactly the same amount of time as each other, to the second.
The voiceover explained during the video that iOS 6 had a much faster shut down time than iOS 7 and this was highlighted in the test.
Each of the phones booted up at different times, but EverythingApplePro highlights that the models differ in the amount of processing power and RAM and software between the newest and oldest phones, meaning this was not unexpected.
The newer models all booted up first, and at almost the same time, yet the original phone booted up faster than the iPhone 4. Apple’s iPhone 3G was the slowest to boost.
