Ask ten people which phone is “most popular” and you may get twelve answers. The more useful question is: popular with whom? Ofcom’s 2025 Technology Tracker shows that UK smartphone choice changes sharply by age. Among 16–24-year-olds, 69% reported using an iPhone as their main smartphone and 31% Android. Among people aged 65+, the balance flips: 41% iPhone and 57% Android.
The national average hides a generational split
Across all UK smartphone users aged 16+, Ofcom reports 54% iPhone and 45% Android. That headline sounds like a straightforward Apple lead. But age breaks the market into very different worlds.
Among 25–34s, iPhone stands at 61% versus 37% Android. For 35–54s, the gap narrows to 52% versus 47%. At 55+, Android moves ahead: 52% Android against 46% iPhone. At 65+, Android’s lead widens to 57% versus 41% iPhone.
Put another way, the Apple-to-Android ratio is about 2.23 to one among 16–24s, 1.65 to one among 25–34s and only 0.72 to one among those aged 65+. The national average is therefore not a universal preference; it is the blend of several quite different age profiles.
What might sit behind the divide?
The Ofcom data shows the relationship, not the cause. It would be tempting to say younger users choose iPhone because of social media, fashion or peer effects while older users choose Android because of price. Those explanations may sound plausible, but this dataset alone does not prove them.
Several factors could matter: ecosystem familiarity, handset price, family influence, upgrade habits, device longevity, accessibility needs, retailer recommendations or simply what somebody has used for years. Smartphone choice is rarely the result of one tidy variable.
Habit may be more powerful than specifications
Phones are unusually sticky products. Once someone has years of photos, passwords, accessories, subscriptions and app habits tied to one platform, switching creates work. The younger an ecosystem captures a user, the longer that relationship can potentially last.
That makes the 16–24 figure commercially important. A 69% iPhone share in Ofcom’s primary-device survey does not just describe one age group; it hints at the power of early ecosystem adoption. Of course, people can and do switch later. But inertia is a formidable competitor, especially when it carries your photos and your mum’s group chat.
The middle-aged group is the real battleground
Among 35–54s, the split is much tighter: 52% iPhone and 47% Android. This group sits close to the national average and may be where platform competition is most balanced.
That matters for businesses targeting mainstream consumers. A campaign, app or service designed only around assumptions from younger users could misread a large part of the market. Cross-platform compatibility is not an optional courtesy when nearly half of a major age band uses the other operating system.
Older users challenge the idea that Apple leads everywhere
At 55+, Android reaches 52% compared with Apple’s 46%. At 65+, the gap becomes 57% versus 41%. For 75+, Ofcom reports 56% Android and 41% iPhone.
These numbers challenge simplistic language such as “Britain is an iPhone market”. Britain overall may lean iPhone, but older groups do not follow the same pattern. A device strategy for healthcare, public services, banking or utilities therefore needs to consider who the audience actually is.
The business implication is segmentation, not stereotyping
Age data is useful for planning, but it should not become caricature. Not every teenager owns an iPhone and not every pensioner carries Android. Percentages describe groups, not individuals.
The better use of the data is practical. If a product team knows its audience skews older, Android testing deserves serious attention. If a service targets students or younger professionals, iPhone optimisation may have greater reach. If the audience spans generations, supporting both platforms well is the only sensible answer.
Why demographic data beats a single market-share headline
A single national percentage is convenient because it fits neatly into a chart. Demographic data is messier, but more useful. The 28-point difference between iPhone share among 16–24s and among people aged 65+ is far larger than the differences Ofcom reports between the four UK nations.
That suggests age is a much stronger axis of variation in this dataset than geography. For marketers, developers and service designers, that is the sort of distinction that can change priorities.
The deeper point
There is no single “UK smartphone user”. There are overlapping populations with different habits and platform choices. The national average is real, but it is only the first layer.
So when somebody says “everyone has an iPhone now”, the polite response is not to argue. It is to ask which age group they have been looking at. Statistics, like family WhatsApp groups, become much easier once you know who is actually in them.
