The iPhone 16 Is Still the World's Best-Selling Smartphone — What Q3 2025 Data Means for Wholesale Stock Planning
In Q3 2025, Counterpoint Research's global handset tracker once again placed the iPhone 16 at the top of the list of best-selling smartphone models worldwide — the third consecutive quarter it has held that position. According to the same tracker, the model accounted for approximately 4% of total global smartphone unit volume, a notable concentration for a single SKU in a market that ships a very large number of distinct models every quarter.
For B2B buyers and wholesalers, the headline ranking is more than a trivia point. It is a data-backed signal about which iPhone generations retain the deepest consumer demand long after launch — and, by extension, which generations will keep flowing into the secondary and refurbished market at scale for years afterward. That has direct implications for how a wholesale stock strategy should be built.

The Data: iPhone 16 Holds #1 for a Third Straight Quarter
Counterpoint Research's quarterly global handset tracker is one of the more closely watched sources for model-level smartphone shipment data, and its Q3 2025 report placed the iPhone 16 in the #1 position worldwide — the third quarter running that the model has topped the list. Per the tracker, the iPhone 16 captured approximately 4% of total global smartphone unit volume in the quarter, a level of concentration that is unusual given how fragmented the broader market is across brands and price tiers.
Apple's strength in the ranking was not limited to a single model. Five of the global top 10 spots were held by Apple devices — the iPhone 16, iPhone 16 Pro, iPhone 16 Pro Max, iPhone 16e, and the newly launched iPhone 17 Pro Max, which entered the list at #10 despite reaching the market only late in the quarter and with limited initial availability. The remaining five spots went to Samsung, but notably all five were Galaxy A-series models, with no Galaxy S or Z flagship appearing in the global top 10.
- iPhone 16 — Apple, #1 globally for the third consecutive quarter
- iPhone 16 Pro, iPhone 16 Pro Max, iPhone 16e — Apple, remaining Q3 2025 top 10 placements
- iPhone 17 Pro Max — Apple, entered the top 10 at #10 despite limited availability late in the quarter
- Galaxy A-series (5 models) — Samsung's entire top 10 share; no Galaxy S or Z flagship placed
Reading the Signal, Not Just the Ranking
A single quarterly ranking is a snapshot, but three consecutive quarters at #1 is a pattern — and the pattern that matters most to wholesale buyers is not which model is newest, it is which model has proven staying power in real consumer demand. The iPhone 16 was not the newest iPhone available for most of the period it led the ranking; by Q3 2025, Apple had already introduced its iPhone 17 line. That a one-generation-back model continued to outsell the newest release, and did so for a third consecutive quarter, points to a durable demand curve rather than a launch-quarter spike.
The composition of the Samsung side of the ranking reinforces the same underlying dynamic from a different angle: none of Samsung's global top 10 placements came from its flagship Galaxy S or Z lines — all five were A-series devices. Across both ecosystems, the models moving the largest unit volumes globally were not bleeding-edge flagships but recent-generation, broadly accessible devices — precisely the profile of device that continues to generate strong resale, trade-in, and refurbishment volume well into its second and third year on the market.
What It Means for B2B Wholesale Stock Planning
For a wholesaler sourcing and grading used and refurbished iPhones, the practical takeaway is that the deepest and most liquid segment of demand is rarely the newest generation. It is the generation that has been in the installed base long enough to generate high device turnover through upgrades, trade-ins, and carrier returns, while still being current enough that end customers actively want it. That is exactly the tier the iPhone 16 occupies today — the same tier the iPhone 14 and iPhone 15 occupied in their own second and third years, and where they largely remain now that the 16 and 17 lines have moved into the spotlight.
Stock strategies that overweight the very newest models chase a segment with limited used-market supply (fewer trade-ins have happened yet) and often thinner margins, while strategies that ignore recent-but-not-newest generations miss the segment carrying the highest, most reliable transaction volume. A wholesale buyer looking to keep working capital efficient and turnover fast typically does best building core depth around the iPhone 14 through iPhone 16 generations, while still maintaining full-range availability — TR Vertriebs GmbH stocks iPhone 11 through the current iPhone 17 Pro Max — to serve retail partners across every price point and market segment.
How TR Vertriebs GmbH Turns Market Signals Into Buyer-Ready Inventory
Translating a market-level signal like this into usable wholesale stock requires a sourcing and grading process that can absorb high volumes of recent-generation devices without compromising consistency. Every unit that enters TR Vertriebs GmbH's inventory goes through a 52-step functional and cosmetic diagnostic using NSYS, PhoneCheck, and Blancco, is IMEI-verified and checked against blacklist and activation-lock (Find My iPhone) databases before it ships, and receives a certified ISO data wipe along with an individual test report. Devices are sorted into three clear grades so buyers can match stock to their own price tiers with predictable, repeatable quality.
As a certified Apple partner operating since 2011, TR Vertriebs GmbH stocks iPhone 11 through the current iPhone 17 Pro Max, with battery health guaranteed above 80% on every grade and every model. Orders start at a minimum of 10 units (MOQ), and if payment is received by 5 PM CET/German time, dispatch happens the same day, with EU delivery typically arriving the next business day, fully insured. Should a unit ever be misgraded, buyers have a 3-day window from receipt to report it with photos and IMEIs, with most valid claims processed within 7 business days and full resolution within 30 business days.

Frequently Asked Questions
Why is a model like the iPhone 16 — already a generation behind Apple's newest release — still outselling the newest iPhone?
Smartphone demand doesn't reset with every launch — a large share of buyers upgrade on cycles that lag the newest release, and carriers, retailers, and trade-in programs keep recent-but-not-brand-new models in heavy circulation. Counterpoint Research's Q3 2025 tracker shows the iPhone 16 holding the #1 global position for a third consecutive quarter, which points to sustained demand across the broader buyer base rather than a short-lived post-launch spike.
Does 'best-selling model' mean the iPhone 16 generated the most revenue in Q3 2025?
No — Counterpoint Research's ranking measures unit shipment volume, not revenue. The iPhone 16 captured approximately 4% of total global smartphone unit volume in the quarter; a higher-priced, lower-volume model could still generate more revenue while ranking lower on a unit basis.
What does this mean in practice for a B2B buyer stocking used or refurbished iPhones?
It reinforces that recent-but-not-newest generations — models like the iPhone 14, 15, and 16 — tend to be the deepest and most liquid segment of demand, combining high device turnover with strong end-customer relevance. Building core wholesale stock depth around that band, while still carrying the full range, tends to produce faster inventory turnover than concentrating purchasing on only the very latest release.
Which iPhone generations and grading options does TR Vertriebs GmbH offer?
TR Vertriebs GmbH stocks iPhone 11 through the current iPhone 17 Pro Max, sorted into three grades — Grade A, Grade A/B, and Grade B/C — with battery health guaranteed above 80% on every grade and every model.
