Buying a used phone saves real money. Selling your old one puts cash back in your pocket. The challenge is knowing which phone to buy, what a fair price looks like, and how to do both without getting burned. This guide covers the full picture and links to deeper guides for every sub-topic.
Quick Answer
Used phones (iPhone, Samsung Galaxy, Pixel, and more) typically cost 30% to 60% less than new while doing the same job. To buy safely, run an IMEI check, confirm Activation Lock is off, and verify carrier compatibility before paying. To sell for the most, wipe your data, price against current market ranges, and list where real buyers are looking. Check current ranges at Swappa’s phone prices page since prices shift as new models launch.
Why Buy a Used Phone
Electronics lose most of their value in the first year. A phone that is one or two generations old often does the same everyday job as the current model at a fraction of the price. You let the original owner absorb the steepest part of the depreciation curve, and you pocket the difference.
The typical used phone discount is 30% to 60% off the original retail price, and sometimes more for older generations of popular models. That figure shifts based on model, storage tier, and condition, so always check current used phone prices on Swappa before buying or selling.
There is also an environmental case. Buying used keeps a working device in circulation rather than contributing to manufacturing demand or accelerating the disposal of something that still functions.

Choosing a Used Phone by Brand
Every major smartphone brand has its own used-market strengths and quirks. Here is a quick orientation with links to the deeper guides.
Used iPhones
iPhones hold resale value better than nearly any other smartphone category. The iOS update window is long, the second-hand market is deep, and premium models like the iPhone 15 Pro and iPhone 14 hold their value across multiple years. The downside is that you pay a premium even used.
Key things to check on a used iPhone: iCloud Activation Lock (must be off before the phone changes hands), battery health (sellers must disclose when health is below 80% and the Apple battery message is showing), and carrier or unlocked status.

Used Samsung Galaxy phones
Samsung’s Galaxy lineup spans flagship (S series), mid-range (A series), foldables (Z Fold and Z Flip), and value editions (FE). The S series depreciates faster than iPhones but offers strong hardware at significantly reduced used prices. Galaxy A phones are the budget standout of the used Android market.
Key things to check: Samsung Reactivation Lock (the Galaxy equivalent of Activation Lock; the seller’s Samsung account must be removed), and whether the phone is carrier-locked or unlocked.

Used Google Pixel phones
Pixels are an underrated used buy. Google now promises seven years of OS updates for recent Pixel models, which gives them a longer useful life. The computational photography system on even older Pixel generations holds up well against newer mid-rangers, and the A series offers the best camera-per-dollar value in the under-$300 used market.
Key things to check: Android Factory Reset Protection (FRP), which can lock the phone to a previous Google account if the sign-out process was skipped.

| Brand | Used discount range | Update support | Key lock to verify |
|---|---|---|---|
| iPhone | 35% to 60% | 5+ years typical | iCloud Activation Lock |
| Samsung Galaxy S | 40% to 60% | 4 years (recent flagships) | Samsung Reactivation Lock |
| Samsung Galaxy A | 30% to 50% | 4 years (recent models) | Samsung Reactivation Lock |
| Google Pixel | 35% to 55% | 7 years (Pixel 8 onward) | Android FRP |
Discounts are typical ranges and vary by model, condition, and market demand.
Unlocked vs. Carrier-locked Phones
“Unlocked” means the phone is not restricted to a single carrier’s SIM. It will work on any compatible network. A carrier-locked phone will only activate on the carrier it is locked to, which limits your flexibility and can complicate resale.
When buying used, unlocked is almost always the safer choice: you have full carrier flexibility, easier MVNO compatibility (Mint Mobile, Visible, and similar budget carriers), and a broader resale market down the line.
That said, a carrier-locked phone is fine if you know you will stay on that carrier and the price reflects the restriction.
There is also a separate issue: financing lock. A phone still under a carrier payment plan cannot be unlocked and cannot legally be sold. This is different from a carrier-SIM lock and will show up on an IMEI check.
On Swappa, the Unlocked category is reserved for Factory Unlocked devices from the manufacturer. We do not allow carrier unlocked devices in the Unlocked category. Carrier unlocked devices must be listed in their original carrier category but they can be described as carrier unlocked in the listing headline and description.

How to Buy a Used Phone Safely
Most risk in the used phone market comes down to two things: whether the device is legitimate, and whether it is in the condition described. Both are verifiable before you pay.
- Run an IMEI check. The IMEI number reveals whether the phone is blacklisted, lost, stolen, or under an unpaid financing balance. Run a free IMEI check on Swappa before committing.
- Confirm the previous account is removed. Apple Account for iPhones, Samsung account for Galaxy phones, and Google account for Android devices. If the previous owner’s account is still on the phone, you will not be able to activate it.
- Check carrier compatibility. Confirm the phone works on your network (Verizon, T-Mobile, AT&T, or your MVNO). An unlocked phone eliminates this variable.
- Review battery health. Swappa requires a fully functional battery that charges and discharges properly. For iPhones, sellers must disclose when battery health is below 80% and the Apple battery message is showing. Lower battery health is normal on used phones. Factor a possible future replacement into your offer if health is low.
- Check the condition against the listing. Screen, ports, buttons, and any signs of prior damage should match what is described.
- Pay through a protected channel. PayPal provides buyer and seller protections and a dispute process.

What Used Phones are Worth: Pricing and Resale Value
Used phone prices shift constantly as new models are announced and older inventory moves through the market. The two biggest factors are model and condition, with storage tier and carrier status adding smaller but real premiums.
A few consistent patterns:
- Flagship iPhones hold value the longest and command the highest used prices in the category.
- Older flagships from Samsung and Pixel often represent the best value-per-feature in the sub-$300 range.
- Timing matters for sellers. Phone values drop meaningfully when successors are announced. Selling before a major launch (typically fall for iPhone, winter/spring for Galaxy) protects your price.
Check current used phone prices on Swappa for live ranges. Treat any price as a snapshot rather than a fixed number.

How to Sell Your Used Phone
Selling privately pays more than trading in. Trade-in programs build in a resale margin and often pay in store credit. A private sale on a focused used-tech marketplace puts cash in your account.
The prep work is straightforward and protects both your payout and the buyer:
- Back up first. Transfer photos, contacts, and anything you want to keep.
- Sign out your Apple, Google, or Samsung account. This is the step most sellers skip, and it is the most consequential. If your account stays on the phone, the buyer cannot activate it, and the sale will fall apart.
- Factory reset. Erase all content and settings.
- Transfer or remove your eSIM if applicable. On current iOS, the Erase All Content and Settings wipe also offers to erase the eSIM profile, so you can clear both in one step.
- Price against current market ranges. Use Swappa’s price data to set a competitive, honest ask.
- Photograph clearly, including any flaws. Honest photos reduce disputes.
- List with specifics: model, storage, carrier or unlocked status, and condition.

Frequently asked questions
Is it safe to buy a used phone?
Yes, when you verify the device before paying. Run an IMEI check, confirm the seller’s account is removed, check carrier compatibility, and pay through PayPal. Buying staff-reviewed listings on Swappa removes most of the guesswork because those checks are built into the listing process.
How do I check if a used phone is stolen or blacklisted?
Look up the phone’s IMEI number. A free IMEI check on Swappa tells you whether the device is reported lost or stolen, blacklisted by a carrier, or carrying an unpaid financing balance. Avoid any phone with a flagged IMEI.
What battery health should I look for on a used phone?
There is no required minimum. Swappa requires the battery to be fully functional (charges and discharges properly). For iPhones, sellers must disclose when battery health is below 80% and the Apple battery message is active in Settings. Lower battery health is normal and acceptable on used phones. Check the listed figure, and if it is low, factor the cost of an eventual battery replacement into what you offer.
Should I buy an unlocked phone or a carrier phone?
Unlocked is almost always the safer used buy. You get full carrier flexibility, easier compatibility with MVNOs like Mint Mobile or Visible, and a broader resale market when you eventually sell. A carrier-locked phone is fine if you plan to stay on that carrier and the price reflects the limitation.
What fees does Swappa charge?
Swappa charges a flat 3% buyer fee (included in the listing price) and a flat 3% seller fee (on the asking price). Listing is always free. Sellers pay payment processing (PayPal 3.49% + $0.49; Stripe 2.9% + $0.30 for select sellers) and buyers pay applicable sales tax. Total fees are lower than auction-site alternatives.
How much can I save buying a used phone instead of new?
Typically 30% to 60%, depending on the brand, model, and condition. iPhones at the premium end hold value and carry smaller discounts; Android flagships and older models often see the steepest markdowns. Prices move constantly, so check current used phone prices on Swappa for live ranges.
