The iPhone 7 and iPhone 7 Plus look a lot like the iPhone 6s and iPhone 6s Plus, with the exception of two new colors. Both iPhone 7 models are the same size, thickness and feature the same screen resolution as their predecessors. One glaring difference is that the iPhone 7 does not ship with the standard 3.5mm headphone jack. Instead both models feature stereo speakers and come packaged with Lighting Connector equipped EarPods.
As with all next-generation iPhone models, the iPhone 7 and 7 Plus received an upgraded processor. Both models are powered by an A10 Fusion chip with 64-bit architecture and M10 motion processor, instead of the A9 chip found on the 6s models.
The iPhone 7 Plus is equipped with "all-new 12MP wide-angle and telephoto cameras" and iPhone 7 is the first 4.7-inch model to ship with optical image stabilization (OIS). There is no change in the iPhone 7's video recording capabilities compared to the 6s. Both the iPhone 7 and iPhone 7 Plus can capture 4k video at 30 fps, just like both 6s models. The FaceTime HD Camera on the iPhone 7 is upgraded to 7-megapixels, instead of 5MP. It also now features auto image stabilization, which is not found on the previous iPhone models.
Other differences include a redesigned Home button, a 25% brighter display with wider color gamut and arguably the most important improvement of all -- an IP67 rating for dust and water resistance up to one meter (3.28 feet).
