A great phone doesn’t need to cost a fortune. In 2025, features once exclusive to high-end devices – big batteries, multi-camera arrays, high refresh rate displays and more – have trickled down to more affordable models. Sure, you’ll still need to buy a flagship smartphone to get the best camera or fastest processor, but you don’t need to compromise nearly as much anymore if you’re looking for a great handset at a reasonable price.
If you’ve been following the news here on Engadget, you know there are always new smartphones coming out to outshine your old handset and inspire some real gadget FOMO. But once you’ve upgraded, what do you do with your old phone? If it’s still in good working condition, chances are that someone out there is willing to shell out a few bucks for your castoff.
