A smartphone market can look wonderfully diverse until the sales chart arrives. Counterpoint Research’s UK model ranking for January 2025 shows just how much demand can cluster around a small number of devices. The top five models accounted for 55% of UK smartphone sales in that monthly table.
Two iPhones took 44% between them
The iPhone 15 Pro Max led with 26% of UK smartphone sales in January 2025, followed by the iPhone 15 Pro at 18%. Together, those two models accounted for 44% of the market measured by Counterpoint for that month.
Samsung’s Galaxy S24 and Apple’s iPhone 15 each held 4%, while the Galaxy S24 Plus held 3%. Add those five models together and the result is 55%.
That is a remarkable concentration. More than half of sales in the table came from five handsets, and nearly half from three Apple models alone.
The top two matter more than the top five headline suggests
The 55% combined share is striking, but the internal shape is even more interesting. Apple’s three listed models contributed 48 percentage points. Samsung’s two contributed seven. Within the combined top-five share, that means roughly 87% came from the Apple models and about 13% from the Samsung models.
That is a derived calculation within the top five, not a total-market brand share. It should not be confused with Statcounter’s installed-usage measure or Ofcom’s primary-device survey. One market, three measurement systems, three perfectly legitimate ways of producing different numbers.
Premium phones can dominate even in a cost-conscious market
The leading two devices were both Pro-tier iPhones rather than entry models. That suggests premium devices can command a disproportionate share during particular sales periods.
There are several possible explanations — upgrade cycles, promotions, contract offers, product launches, consumer preference — but the January ranking alone cannot identify which caused the result. A monthly sales table describes what happened; it does not automatically explain why.
A monthly chart is a photograph, not a biography
This is the most important caution. January 2025 is one month. It is not the whole of 2025, and certainly not the current 2026 market. Product launches, discounting and stock availability can change rankings quickly.
That does not make the data weak. It makes it specific. Monthly data is excellent for understanding moments of concentration, launch momentum and competitive intensity. It becomes misleading only when a specific period is quietly promoted into a universal truth.
Why model concentration matters to retailers and developers
For retailers, concentrated model demand can influence inventory, accessories, insurance products and trade-in activity. If a few models dominate, cases, chargers and repair parts for those devices may move more quickly than the long tail.
For app developers and QA teams, high model concentration can also guide testing priorities. A product should still support the broader device base, but knowing which handsets are particularly common can help determine where early regression testing delivers the greatest practical coverage.
But installed base may tell a different story
A device that sells strongly today does not instantly dominate phones already in use. Older models remain active for years. This is why model-sales rankings and installed usage should not be expected to match.
A January sales surge may be commercially significant while representing only a small change in the total installed population. Conversely, an older model can remain widely used long after leaving the bestseller list.
What the ranking says about competitive visibility
When five models take 55% of sales, the remaining market is fragmented across many devices. That can make visibility difficult for smaller brands and models. They are not merely competing with Apple and Samsung at company level; they are competing with a handful of extremely visible individual products.
Retail placement, carrier promotion and brand familiarity can therefore reinforce one another. The more visible a handset becomes, the easier it is for buyers to recognise it, compare it and find accessories for it.
The useful conclusion
The January 2025 ranking tells us that UK smartphone demand can become heavily concentrated at model level, not merely brand level. The top two models alone were responsible for 44% of the measured monthly sales, and the top five for 55%.
That is not proof that Britain only buys expensive phones, nor that the same models dominated every month. It is evidence that, in at least one measured month, a small group of devices captured an unusually large share of attention and purchases.
In other words, the smartphone aisle may contain fifty choices, but the till receipt can be rather less democratic.
