The iPhone 7 came out a few weeks ago in this video you can see it being compared to the 2G which is Apples first iPhone. You can see that the iPhones are different in size straight away as the iPhone 7 is a lot larger but also thinner than the iPhone 2G.
First of all the iPhone 7’s touch ID home button which isn’t really a home button as it doesn’t actually click. On the other hand, the iPhone 2G has a button that clicks but doesn’t have touch ID. The iPhone 7 doesn’t have a headphone jack but the iPhone 2G does although it’s positioned at the top of the iPhone instead of at the bottom near the charging port. As you can see both devices have a different charging port as the iPhone 2G is much larger than the iPhone 7.
The iPhone 7 is water and dust resistant whereas the iPhone 2G is not. The other differences include the speaker sound which is a lot better on the iPhone 7 compared to the iPhone 2G. The screen sizes are different as well as the 2G has a 3.3″ size screen compared to the iPhone 7 which has a 4.7″ screen. The resolution, colours and sharpness of each screen are completely different to the other with the iPhone 7 having a better screen overall which you would expect from a newer device.
The iPhone 2G had a ARM 11 processor, 128 MB of RAM & you could choose from 4, 8 or 16 GB of storage. In contrast to this, the iPhone 7 has the A10 fusion processor, 2GB of RAM, 32, 128 or 256 GB of storage. You can see how different they are in terms of specifications as well as the design. The iPhone 7 is 120x faster than the first iPhone which makes it one of the fastest iPhones around. The original iPhone still works well even using it today which shows that from the beginning Apple knew what they were doing when it came to smartphones.
