Deep-pocketed power users may buy new smartphones once a year or even every few months to take advantage of improved displays, better cameras and faster processors, but the majority of owners are more likely to tire of their device's appearance long before its outdated specs. A few manufacturers have taken a new approach when designing their handsets, opting to include not only replaceable batteries, but also swappable backs, that let you change the look of your phone for only a few bucks. Samsung's Galaxy S5 and LG's G3 are two recent flagships that you can change up after purchase, but there are a few other options to consider, too. If you're feeling extra ambitious, you could even replace the backplate on, say, an iPhone 5s, but such an undertaking requires precise work, pricier parts and a voided warranty.
