So here is everything you need to know about the difference between iPhone 7 and iPhone 8 and decide whether it is a worthy upgrade?


When you look at iPhone 7 and iPhone 8, you find them really indistinguishable. The design of both of the phones is almost the same. The only difference is that the iPhone 8 is bigger in size than iPhone 7 and also 7% heavier because the back of the iPhone 8 is glass and not aluminum.

  • iPhone 8 - 138.4 x 67.3 x 7.3 mm (5.45 x 2.65 x 0.29 in) and 148g (5.22 oz)

  • iPhone 7 - 138.3 x 67.1 x 7.1 mm (5.44 x 2.64 x 0.28 in) and 138g (4.87 oz) 

Display  (LCD Screen)

The iPhone 8 comes with a true tone technology from the iPad pro range which reacts to environmental light and ensures a correct color balance all the time. iPhone LCD Screens also supports Dolby vision and HDR10 for a higher dynamic range. But the iPhone 8 does not match the contrast ratio (1400:1) or brightness (625 cd/m2 max) of iPhone 7. 


iPhone 7 and iPhone 7 plus were considered the fastest smartphones in the world, but this was before iPhone 8 was launched. iPhone 8 is much faster and smarter with the following features:

  • Six-Core CPU

  • Six-Core GPU

  • M11 motion coprocessor

  • 3GB RAM ( iPhone 8 Plus), 2GB RAM (iPhone 8) 


  • The iPhone 8 has a 12 megapixel wide-angle camera  f/1.8 aperture

  • optical image stabilization plus a 7 megapixel

  • f/2.2 camera on the front - both identical to the iPhone 7. 

Battery life

There is both a good news and a bad news when it comes to battery life. Even Apple admits that the iPhone 8 lasts about the same as iPhone 7. The good news is that iPhone 8 has a feature of fast and wireless charging.

Overall, one must not buy iPhone 8 just for its looks and display as it is very identical to the iPhone 7. When it comes to storage, it has been doubled up but the prices have been raised too.
