The first iPhone hit the market in June 2007, and regardless of your opinion about Apple, one thing is certain: in the nine years since, the iPhone has evolved enough to shed its reputation as a "high-risk bet" and become the standard by which the rest of the industry measures itself. How much has it really changed? The best way to find out is to line up all fifteen iPhone models side by side and watch them work.
Apple's Flagship, Generation After Generation
Let's not kid ourselves: the iPhone is Apple's number one product. On the surface, each generational leap looks a little more conservative than the last, but with a billion devices sold worldwide, it's hard to blame Cupertino for being extremely cautious with anything iPhone-related. The removal of the traditional headphone jack on the iPhone 7 and 7 Plus set off enough alarm bells that Apple clearly understands the need to measure every change with precision and care. Several specialist outlets believe Cupertino saved a lot of its firepower for the next iPhone, which will mark its tenth year on the market, and it's easy to understand the criticism of a "stagnant design." The most direct way to test that idea is to put all fifteen models on a table and compare their core functions and performance.
A Brutal Performance Test
The EverythingApplePro channel took on this Herculean task, and that's no exaggeration: it's already difficult enough to find a mobile device over nine years old that still works like day one and can run benchmarks. The differences between the original iPhone and the 7 Plus are genuinely staggering. Apple claims the 7 Plus is 120 times faster than that first-generation iPhone, now a museum piece. Even so, the aging smartphone managed to take ninth place in the boot test, while the iPhone 4S running iOS 9.3.5 came in last. This is a reminder of how important it is to choose the right iOS version for each iPhone. Newer versions are more secure, but the performance hit can turn the device into a nightmare.
Heat and Cameras
A common complaint about other smartphones is how hot they get during normal use, but the iPhone managed a solid average across all fifteen models, staying between 30 and 40 degrees Celsius. To close things out, the video compares camera quality on every iPhone, and that's where the biggest differences show up. Sure, 2 megapixels versus 12 isn't exactly a fair fight, but there are nine years between them. Time passes, even for technology.
