iPhone 7 vs iPhone X Comparison

iPhone 7 vs iPhone X: a vintage match-up!

The iPhone 7 and the iPhone X are two of Apple's most popular vintage smartphones. The iPhone 7 was released in 2016, while the iPhone X was released a year later in 2017, making it the more recent device.

iPhone 7 vs iPhone X: camera quality

When it comes to camera quality, both devices share a 7 MP selfie camera, but the rear camera is where they both differ from each other; the iPhone X sports a dual camera 12 MP system with wide and telephoto lenses, whereas the iPhone 7 only has a single camera setup which is a wide lens.

iPhone 7 vs iPhone X: size, battery, and design

Regarding the display size and resolution of the two devices, they both start to get more different from each other; the iPhone 7 has a 4.7 inch display with 750 x 1334 px resolution while the iPhone X has a 5.8 inch display with 1125 x 2436 px resolution, indicating you’ll likely have a better content viewing experience with the iPhone X. The battery life of each device also shows a stark contrast; The battery capacity of the iPhone 7 is 1960 mAh which can last up to 10 hours when web browsing or video streaming whereas the battery capacity of the iPhone X is 2716 mAh which can last up to 14 hours - again another point to the iPhone X here. In terms of design, both devices have sleek designs but what is obvious is the removal of the button and bezel on the iPhone X. In addition to this, is the weight difference too; the weight of an iPhone 7 is 138 g whereas an iPhone X is much heavier at 174 g. Both devices come in various colors such as black, silver and gold but the iPhone 7 provides a wider range of colors with red, gold and rose gold which is not offered in the iPhone X model. In terms of storage capacity, both phones offer storage options as high as 256GB, but regarding RAM capacity, The iPhone 7 is inferior slightly with 2 GB RAM while The iPhone X has 3 GB RAM for faster performance speeds. For iOS, the iPhone 7 is upgradable to only iOS 15.7, but the iPhone X can upgrade to the latest which is 16.3.

No contest: iPhone X is your best bet!

Overall, the newer iPhone X model offers better technical specifications than slightly older iPhone 7 - It provides higher screen resolution, longer battery life, higher RAM capacity and is upgradable to the latest iOS so that it’s indifferent to even the latest model’s operating system (iPhone 14 series). All evidence is pointing towards the iPhone X as the clear-cut winner in this battle.At Back Market we believe that buying refurbished products helps reduce our environmental impact by reducing waste production from manufacturing new products from scratch.
