Alternatively, you may not be a fan of the chunky designs that most modern smartphones have, preferring to have a smaller handset that you can fit in your pocket. If this is the case, consider the iPhone SE 2020 with a screen that measures just 4.7-inches. Both the iPhone 8 and iPhone 7 have a similar-sized screen, although you can get even smaller by going for even older models - although you may be disappointed with their performance.
