Things to look out for when buying a second-hand smartphone
New smartphones aren’t getting any cheaper — and with global trade tensions threatening to drive prices even higher, more consumers are turning to the booming secondhand phone market for a better deal. If you’re one of them, here’s what you should keep in mind before making that purchase.
The growing market for used phones
According to U.K.-based tech research firm CCS Insight, the market for used smartphones is now growing faster than the market for brand-new devices. As each flashy new model is announced, millions of people upgrade and trade in their still-fully-functional phones — creating a healthy inventory of secondhand options.
Refurbished devices, in particular, are an attractive choice. CCS Insight reports that they can cost up to 50% less than a new phone and often come with warranties, financing options, and customer service support.
Where to buy secondhand phones
While the internet is filled with options, it’s also full of scams. The best advice: stick to reputable, specialized platforms like Gazelle, Backmarket, or big retailers such as Best Buy and Amazon. Even Apple and Samsung now sell certified refurbished models on their own sites — which means you’ll get a reliable, professionally inspected device (though usually with less dramatic discounts).
Another option is buying directly from your wireless carrier or through trusted peer-to-peer marketplaces like eBay or Swappa, which offer buyer protections if a product isn’t as advertised.
Which phones are the most popular?
If you’re an Apple fan, you’re in luck — iPhones account for about 60% of the global secondhand market, according to CCS Insight. Samsung follows with roughly 17%, with other Android brands like Xiaomi trailing behind.
Watch out for the battery
A critical factor in a phone’s lifespan is its battery. Not all refurbished phones come with new ones. Apple and Samsung guarantee new batteries (and in Apple’s case, a new shell too) with their refurbished models. Other sellers might only promise that a battery retains at least 80% of its original capacity, so always check the fine print.
Understanding condition ratings
Refurbished phones are typically graded by condition — but be cautious. Each platform has its own grading system, with terms like Good, Very Good, Excellent, or Like New. Since there’s no industry standard, comparing across platforms can be tricky.
“It makes it difficult to shop around,” says Simon Bryant, VP of research at CCS Insight. A phone marked Grade A on one site might be labeled Excellent on another — with very different price tags.
How old is too old?
Bryant recommends sticking to phones no more than three generations old. Devices older than five or six generations likely won’t receive the latest software updates, which can leave them vulnerable and less functional.
“Three generations is the sweet spot,” says Bryant. “It’ll have relatively new features and won’t be too worn out.”
Check for stolen phones
Most online marketplaces have safeguards to keep stolen devices off their platforms. But it’s still smart to check a phone’s IMEI number — dial *#06# to retrieve it — against a database like Swappa’s checker to confirm it hasn’t been blacklisted.
Water damage and accessories
Even water-resistant phones can be damaged if moisture gets inside. If buying in person, check the phone’s liquid contact indicator — Apple and Samsung both provide online guides for finding it.
And remember: cables, chargers, and earphones might not be included with your purchase, so factor those extras into your budget — written by Kelvin Chan, Associated Press journalist.
Bottom Line:
Buying a secondhand phone is a smart way to save money in today’s pricey smartphone market — but it’s not quite as simple as picking up a new device. Do your homework, choose a trustworthy seller, and know what to look for to avoid surprises.
