Which Phones Flip Best on eBay: Models, Conditions, and What to Avoid

iPhones lead. Everything else is a side lane.

If you remember nothing else from this page: a solo eBay flipper who anchors on unlocked iPhones 1–3 generations behind current, in honest Used condition, with a clean IMEI, will out-earn the same operator chasing Pixels, foldables, or budget Androids by a margin that compounds every month. Apple's resale dominance is structural — slower depreciation, deeper buyer pool, deeper aftermarket parts supply, tighter sold-comp spreads. Samsung Galaxy S Ultras and Pixel 9-series are real lanes, but they are the second and third lanes, not the first. Every dollar of sourcing capital you allocate to the wrong brand or wrong condition tier earns less per turn and risks more per return. This page tells you the lane. It does not tell you where to source (that's Topic 1), how to test (Topic 3), or how to price the buy (Topic 6) — those have their own pages in the guide.

Why iPhones are the default — and the 1–3 generation sweet spot.

Apple controls iOS updates, runs a single App Store, and ships a small, well-understood product hierarchy that buyers can verify without technical knowledge. Translated into resale: tighter eBay sold-comp spreads, faster sell-through, a wider buyer pool across every carrier and age bracket, and an aftermarket parts supply (screens, batteries, back glass, charging ports) that survives the repair-flip math.

Across 2026 depreciation data from SellCell, BankMyCell, and CompareAndRecycle, iPhones depreciate roughly 10 percentage points slower in year one than the equivalent Samsung flagship and far slower than any Pixel. The productive sourcing band is the iPhone 14, 15, and 16 lines while the iPhone 17 is the current generation — old enough that sourcing prices have compressed, new enough to still be in the iOS software-support window where most buyers shop.

Indicative US resale ranges (Used, unlocked, 128 GB unless noted)

Treat every figure below as directional, self-reported, and current as of May 2026 — re-verify before launch. These are sold-comp anchors, not guaranteed exits.

The storage-ladder rule

The single biggest leak on iPhone sourcing is paying flat for 128 GB when 256 GB sells for materially more. On the iPhone 14, the 256 GB Swappa sale average is roughly $45 above the 128 GB average. If the seller's 256 GB premium is under $40, take the upgrade — the resale spread typically more than covers it. Walk past sellers pricing the storage tier above what the market actually pays at exit.

The floor models thin out fast

iPhone 12 and older are workable but thin. The iPhone 11 in good condition fetches roughly $120 at buyback aggregators and perhaps $130–$145 on eBay net of fees (re-verify before launch) — a narrow window that demands sub-$70 sourcing to be worth the time. iPhone SE 2nd-gen trade-in tops out around $115 with average resale around $22 — skip unless someone gives it to you.

The second lane: Galaxy S Ultras only, and Pixel as opportunistic.

Samsung's Galaxy S series retails at flagship prices and depreciates materially faster than iPhone. The Galaxy S25 lost roughly 46.6% of its value at five months post-launch vs roughly 35.4% for the iPhone 16 at the same mark — an 11.2-percentage-point delta that compresses margin every month it widens (SellCell, re-verify before launch). The lane is still real, but the productive subset is narrower than iPhone.

Buy: Galaxy S Ultras (S23 / S24 / S25)

Ultras hold value better than non-Ultra Galaxy S models in absolute dollars because the S Pen and camera package draws a buyer pool that does not cross-shop iPhone. Indicative US figures (re-verify before launch):

• Galaxy S23 Ultra — Swappa average ~$309 in Used condition; retail range up to roughly $386. The most accessible Ultra tier.
• Galaxy S24 / S24+ / S24 Ultra — S24 Ultra good-condition buyback ~$565; standard S24 ~$216. Ultra is the lane, not the standard model.
• Galaxy S23 / S22 (non-Ultra) — S23 average ~$237, S22 average ~$155. Thin margin, slow comparative velocity. Default to Ultra.

Skip: A-series, FE-series, Note line

The Samsung A-series (A14, A15, A25, A35) depreciates catastrophically — 50%+ in year one and 85%+ by year two on most budget Android. The Samsung A50 lost roughly 80% of trade-in value within 21 months. The FE-series creates naming-confusion search noise that depresses ranking and price. The Note line is discontinued with no first-party updates. None of these produce repeatable eBay margin.

Foldables: high ticket, specialist play

Galaxy Z Fold and Z Flip lose roughly 63.7% of value in 6 months and 65.8% in 12 months — about 15 percentage points worse than the standard Galaxy S over the same windows (SellCell). Display repair on a foldable costs multiples of a slab repair, and buyers are more likely to return citing hinge resistance, inner-display delamination, or a worsened crease. Indicative ranges:

• Galaxy Z Flip7 — average ~$434 in Used, range roughly $260–$580 (re-verify before launch). Workable only at the low end of the range.
• Galaxy Z Fold (current) — higher ticket, narrower buyer pool, better retention than Flip on percentage basis but more capital at risk.

Critical seasonality note: foldables drop roughly 8–10% in the eight weeks after a Samsung Unpacked launch. The Flip 5 256 GB dropped roughly 14.4% (~$59) in that window (re-verify before launch). Never hold a foldable through Unpacked.

Pixel: opportunistic only

The Pixel 9 represents Google's best resale to date and still trails iPhone materially. Indicative Swappa 128 GB pricing (May 2026): unlocked listings average ~$399 with average sale ~$362, vs ~$343 for Verizon-locked. Pixel 10 first-year depreciation around 63%; older Pixels collapse from there — Pixel 7 in good condition fetches roughly $78 at best buyback (re-verify before launch). The Pixel buyer pool on eBay is narrower than iPhone at every comparable model and storage. Only touch a Pixel when acquisition cost is meaningfully below the sold-comp median net of fees, shipping, and a return buffer; otherwise the iPhone shelf is the better trade.

Solo sellers get four condition tiers — and one of them is a trap.

Before sourcing decisions get made, the eBay rules need to be straight. In the cell-phone category, a solo seller's condition choices are exactly four: Used, New, Open Box, and For parts or not working. The Excellent / Very Good / Good condition tiers exist on eBay but are gated to certified refurbished sellers — they are not available to solo flippers. Best Offer is not available in the cell-phone category either (re-verify before launch); list fixed-price as Good 'Til Cancelled.

Condition delta often exceeds brand delta

The same phone in two condition tiers can swing more than the gap between two different phones. Galaxy S23 Ultra in Used resells around $309 on Swappa; the same model listed broken or faulty tops out around $75 — a $230+ swing on the same device (re-verify before launch). iPhone 14 in good condition fetches roughly $332 at buyback vs $151 cracked — a $181 gap. That gap is the entire repair-flip math: if the screen repair costs less than the gap minus fees, the play works.

Repair-flip math (illustrative, self-reported, not typical)

A Medium operator self-reported an iPhone 12 sourcing strategy: $200 broken acquisition, $80 screen + battery parts, ~3 hours labor, $450–$500 resell, ~$170–$220 net per device. Multiplied across roughly 400 devices/year, that operator self-reported ~$65K annual. Treat the entire example as illustrative, self-reported, and not typical — your sourcing pool, repair access, repair speed, and exit prices will differ.

Volatile cost inputs that move with supply — re-verify before pricing any repair flip:

• Apple OEM screen repair (out of warranty) — $129 (SE) to $379 (16 Pro Max / 15 Pro Max / 14 Pro Max) (re-verify before launch).
• Aftermarket screen kits — $35–$160 by model and grade (re-verify before launch).
• Wholesale parts — budget Incell LCD for iPhone 14 Pro $18–$25; Soft OLED for iPhone 15 Pro Max $70–$90 (re-verify before launch).
• Samsung flagship screens — $150–$250 installed; curved OLED more (re-verify before launch).

The condition tiers in plain English (solo seller)

• New — Sealed, factory-fresh. Highest exit price, but also highest entry cost. Buyer expects mint and full warranty; returns are devastating to margin. Almost no sourcing arbitrage at retail-adjacent pricing.
• Open Box — Unsealed, otherwise new and unused. Niche but real for unredeemed carrier promo phones and retailer returns.
• Used — Functional, may have minor cosmetic wear. The biggest-volume tier and the bread-and-butter for solo flippers. Battery health matters: state it explicitly in the listing. iPhone buyers ask in messages before bidding.
• For parts or not working — Cracked screens (even if powers on), iCloud/FRP-locked, blacklisted, water-damaged, or otherwise non-functional. Buyer pool is repair shops and parts harvesters. Prices deeply discounted but the listing is honest and the dispute exposure is low.

Sell-through rate, defined correctly.

Sell-through rate (STR) is the single most-misused number in this niche. The correct formula a solo flipper should run for every candidate model:

This is not sold ÷ active. Do not use an inverted ratio that makes slow-moving inventory look healthier than it is. The clean version is sold over the total population of sold-plus-active, expressed as a percentage. Run it once with eBay's Sold filter applied for your window, run it again with the filter off to count active listings, then divide.

What threshold to target

Target sell-through rate above 50% for the unlocked-recent-iPhone band (iPhone 13 through 16). Below 50% on Samsung Galaxy or Pixel signals a slow mover that will tie up capital — accept it only with strong sourcing discount to compensate. Below 30% on any model means inventory that sits 60+ days, and capital that sits earns nothing.

Velocity beats sticker price

The compounding metric is sell-through, not gross margin per unit. A 5% margin on a 5-day flip cycles working capital roughly six times per month. A 25% margin on a 60-day flip cycles it half a month — and that half-month is exposed to one launch event, one carrier promo, or one bad review. Unlocked recent iPhones in Used or better clear in 3–7 days; carrier-locked equivalents take 2–4× longer. Cassini (eBay's search algorithm) also rewards consistent week-over-week velocity, which compounds the advantage.

Always read raw counts alongside the ratio

Six solds in 90 days is two per month no matter how the ratio frames it. A thin market can still look attractive if you only read the percentage. Read both numbers: the percentage and the raw sold count. Stock only models where the raw monthly volume supports your weekly turn target.

The five inventory types that destroy margin.

This is the signal-level avoid list. Test mechanics — exactly how to verify each of these before payment — belong to Spoke 3 (Testing). What follows is the pattern recognition that filters candidates before you even reach the test step.

1. Carrier-locked (especially prepaid / MVNO)

Carrier-locked iPhones sell 10–20% below unlocked equivalents at the same generation and storage; prepaid and MVNO locks (TracFone, Metro by T-Mobile, Cricket, Boost, Straight Talk, regional brands) carry deeper discounts and a narrower buyer pool. Unlocked Galaxy S24 lists at roughly $383 on Swappa vs ~$282 for Cricket and ~$236 for Boost-locked — a $100–$150 spread (re-verify before launch). Locked phones also take 2–4× longer to clear. As a third-party buyer you generally cannot initiate a carrier-unlock request — that path requires the original account holder. Default to unlocked. Buy locked only when the discount is real, verified, and priced at exit as locked.

2. iCloud / Activation Lock (iPhone)

Apple's Activation Lock ties a device permanently to its owner's Apple ID after a factory reset. There is no legal, reliable bypass for iPhone 8 and later — every online service advertising iCloud removal is either a scam or uses methods that leave the device in an unstable jailbroken state that re-locks on reboot or after any iOS update, and which do not restore App Store, calls, Messages, or iCloud functionality. A phone with Activation Lock the seller cannot clear is a For parts or not working unit — full stop.

3. Google FRP (Factory Reset Protection) lock

Android's equivalent of Activation Lock. A device that was factory-reset without first removing the Google account requires the original credentials at setup wizard. Android 16 hardens this by triggering an additional factory reset if a setup-wizard bypass is detected. FRP-locked Pixels and Samsungs share the iCloud-locked iPhone resale ceiling: parts only.

4. Blacklisted / bad-ESN IMEI

A blacklisted IMEI means the device was reported stolen or carries an unpaid balance and has been blocked from major US networks. The only path to clearing a blacklist runs through the carrier that filed the report, with the original account holder. Free checkers worth running before any purchase: IMEI24.com, IMEIcheck.com, IMEIpro.info, IMEI.info, Swopsmart, and doctorSIM (re-verify before launch — third-party services and their free limits change). For any device with a sourcing cost above $200, a paid CheckMEND-style IMEI report (~$3–$5, re-verify before launch) is cheap insurance.

5. Financed / unpaid balance

A phone still under a carrier installment plan (Verizon Device Payment, T-Mobile EIP, Apple iPhone Upgrade Program) will be blacklisted if the original account goes delinquent — typically 30–90 days after your purchase, well inside eBay's buyer protection window. The IMEI may scan clean on the day you buy and go bad two months later. Run a financial-status check on top of the blacklist check. Get the seller's explicit written statement (in the eBay message thread or text) that the device is fully paid off. If the seller cannot or will not confirm, walk.

Plus: water damage and software-cutoff devices

Water damage is progressive and largely invisible at purchase — a phone that powers on today can fail at the 20-day mark, inside eBay buyer protection. Liquid Damage Indicator triggered (red/pink) = parts donor only. Software-cutoff devices (iPhone SE 1st gen, Galaxy S9 and earlier, Pixel 5 and earlier) lose the iOS/Android-update-window buyer pool and listings sit. Skip both categories.

Five-step decision sequence: which phone, which condition, why.

This is the model-and-condition decision filter. Pricing math, sourcing channels, and lock/IMEI testing each have their own spokes — this sequence narrows the universe to candidates worth running through those checks.

1. Anchor on unlocked iPhone in the 1–3 generation sweet spot — currently iPhone 13, 14, 15, and 16, in 128 GB or higher, with iOS still in the support window. This is the lane with the highest buyer pool, the deepest aftermarket parts supply for repair flips, and the tightest sold-comp spread. New flippers should not stray from this lane until iPhone volume is steady.
2. Layer in Galaxy S Ultras and Pixel 9-series only as a secondary lane — once iPhone velocity is consistent, the Galaxy S23 / S24 / S25 Ultras and the Pixel 9 / 9 Pro / 9 Pro XL extend the addressable pool with non-iPhone buyers. Skip Samsung A-series, FE-series, the Note line, foldables (unless you are running mid-cycle and accepting specialist risk), older Pixels, and budget Android entirely.
3. Match condition to eBay's solo-seller categories — Used, New, Open Box, or For parts or not working. A cracked-screen phone must list For parts, not Used, even if it powers on. Excellent / Very Good / Good are gated refurbished tiers and not available to a solo seller. Best Offer is not available in the cell-phone category — list fixed-price Good 'Til Cancelled (re-verify before launch).
4. Filter out the avoid list before testing — carrier-locked (especially MVNO/prepaid), iCloud or Activation-locked, Google FRP-locked, blacklisted/bad-ESN IMEI, financed or unpaid balance, water-damaged, and software-cutoff devices. A candidate that pattern-matches any of these is parts-only at best and an account risk at worst.
5. Validate against eBay sold comps and sell-through rate — pull sold listings for the exact model + storage + lock status + condition, calculate STR = sold ÷ (sold + active), target above 50%, read the raw sold count alongside the ratio, and use the median sold price (not the active asking price) as your exit anchor. Pricing math (working backward from comps through fees and shipping to a maximum buy price) sits in Topic 6.
