Follow every tip you can to get good money for your old phone.Angela Lang/CNET
So you want to sell your old Android phone or iPhone now, or think you might want to one day? Maybe you're eyeing a new device, like the iPhone SE, Galaxy A51 or OnePlus 8 ($699 at Amazon) and want to recoup some of the costs. Or perhaps you have older phones laying around that you don't really use and haven't repurposed. Or maybe you're simplifying by moving from a pricier model, like the Galaxy S10 Plus ($500 at Amazon) or iPhone XS ($899 at Amazon), to a cheaper phone and you just want a little more cash in your pocket.
Whatever the reason, it's important to know your options for selling your phone or trading it in to a carrier, or using a peer-to-peer marketplace like Craigslist or Facebook Marketplace, and how to get the most money for your device. While you can't control the rate of phone depreciation, selling a device in good condition could make hundreds of dollars of difference. The key is to think about these things now, not days before you're ready to move on. Here's what you need to look out for.

Whatever you do, don't skip the case
Yes, it's ugly. Yes, you need one: You probably already use a case to keep your phone's delicate glass screen and back from breaking. We know, we know, it ruins the appeal of a particularly slick gradient color or design, but if you want to keep your phone free of dents and cracks when you sell it, a case is the way to go.
Smart tip: Buy the case before you start using your phone. Phones can and do drop and shatter within minutes of coming out of the box.
What to look for: Complete coverage all around the edges, and some sort of rise -- even a small one -- between the screen and the lip of the case.

Buy a screen protector. Now
Why you need it: Screen protectors are sacrificial screens that you layer on top of the phone's original display -- buy a glass one, not plastic. There are oodles of them in your carrier store and online. A good one can cost you, but a $30 screen protector is worth it in the long run if it helps you nab hundreds of dollars more for your phone when it comes time to sell it or trade it in.
Keep a spare: Screen protectors can break when you drop the phone -- that's what they're for. It's not a bad idea to keep a spare on hand in case yours breaks, so you won't have a gap in protection if you do need to switch it out. If you don't need it and you sell your phone on the open market, you can bundle in the screen protector as part of the price.

Keep the box and all the parts
Really!: Carriers will prefer to have your original charger, but may not care about the box when you trade-in a phone. But if you sell the phone through Craigslist or Swappa, for example, your buyer will. Reboxing the phone in its original condition -- or as close as you can get to it -- will make your device more appealing, which will translate into more bucks.
What about the case? You can sell that, too.

Really clean your phone before you sell it
Cleanliness is money-ness: This one's important, whether you sell your phone to a stranger, through a third-party reseller like Decluttr or back to the carrier or manufacturer. You'll get more for a phone that looks and works like new than you will for a crusty handset that's merely limping along.
Since you won't get paid until the buyer inspects your device, you may not wind up with your asking price if the used phone doesn't match up to expectations. Cleaning your phone the right way before sending it in is well worth the effort.
What about the parts? Wipe down the box and case with a lightly damp cloth or paper towel, too. Nobody's buying your grime.

Repairing a cracked screen could be worth it
Work the math: You might wind up with more in your pocket if you repair a broken phone (e.g. through U Break I Fix or Apple stores) before trying to sell it to a third-party reseller or trading it in.
Why even bother? Broken phones still retain some value because they can be refurbished or stripped for parts to either recycle or repair other phones for resale.
How to tell: Go on a third-party reseller site or your carrier's trade-in site to see how much they estimate the value to be for your cracked-screen or water-damaged phone, versus the value for a phone with no damage. Then compare that to the cost of a repair. If there's enough of a difference (e.g. your phone is fairly new or in high demand), it might be worth the hassle.
What else do I need to know?
In all cases, you'll need to back up your phone and return it to factory settings before handing it off. This will help protect your identity and make sure you keep all the photos and other data you need to switch over to a new device.
