You’ve seen them everywhere. On the subway, in the grocery line, or likely right in your own hand as you read this. But have you ever actually stopped to wonder just how massive the "Apple Cult" has become? It’s a lot bigger than most people realize.
Honestly, tracking the exact number of people who use an iPhone is a bit of a moving target. Apple stopped reporting individual unit sales years ago—probably because they’d rather you look at their "Services" revenue—but analysts have gotten pretty good at counting the heads in the walled garden.
As of early 2026, the numbers are staggering. We are looking at roughly 1.64 billion active iPhone users globally.
Think about that for a second. That is nearly one out of every five people on the planet. Not just people with electricity or internet, but everyone.
Where Are All These People?
It’s easy to assume everyone has an iPhone if you live in New York or London, but the global split is actually pretty wild. In the United States, the iPhone is basically the default setting for anyone under 30. Recent data from analysts at Counterpoint Research and Omdia shows that Apple’s share of the U.S. smartphone market has hovered around 57% to 60%.
In the U.S. alone, over 155 million people are active iPhone users.
But go to India or Brazil, and the story shifts. In those markets, Android is still king because of the price point. However, Apple has been playing a long game. By pushing older models like the iPhone 13 and 14 into these emerging markets at lower price points, they’ve managed to see double-digit growth in regions where they used to be a niche luxury brand.
The Loyalty Factor (Or Why Nobody Leaves)
Why is the user base still growing? It’s not just the hardware. It’s the "stickiness."

According to consumer surveys from CIRP (Consumer Intelligence Research Partners), iPhone loyalty remains incredibly high, often north of 90%. Once you have the blue bubbles in iMessage, the iCloud storage for your photos, and an Apple Watch on your wrist, switching to a different brand feels less like a tech upgrade and more like moving to a different country where you don't speak the language.
- The Gen Z Grip: In the U.S., nearly 87% of teenagers own an iPhone.
- The Gender Split: Globally, it's pretty even, though some regions show a slight lean toward female users (around 54%).
- The Spending Gap: This is the part Wall Street loves. Even though there are more Android users globally, iPhone users spend significantly more on apps. In 2025, consumer spending on the iOS App Store hit roughly $142 billion, nearly double what was spent on Google Play.
The Most Popular Models in 2026
You might think everyone is rushing out to get the latest iPhone 17 or whatever the newest Titanium-wrapped slab is, but the data tells a different story.
The "Golden Child" of the lineup right now isn't actually the newest one. The iPhone 13 and iPhone 15 Pro Max are currently the heavy hitters in the active install base. People are holding onto their phones longer. The average upgrade cycle has stretched out to about 3 or 4 years for many users.
Because Apple supports their devices with software updates for so long—often 6 or 7 years—an iPhone bought in 2020 is still a perfectly viable daily driver today. That longevity is exactly why the "active user" number keeps climbing even when year-over-year sales sometimes look flat.
Is the Growth Finally Slowing Down?
Kinda. But also, not really.

Apple CEO Tim Cook mentioned in recent earnings calls that their "installed base" reached an all-time high in every geographic segment. They are basically running out of new humans to sell to in the West.
To combat this, the strategy has shifted toward "premiumization." They aren't just trying to sell you a phone; they want to sell you the most expensive version of that phone. And it’s working. The "Pro" and "Pro Max" models now make up a larger percentage of total sales than the base models did five years ago.
What This Means for You
If you’re trying to figure out if you should stick with the ecosystem or if you're a developer wondering where to put your energy, the trend is clear. The iPhone isn't just a phone anymore; it's a massive, self-sustaining economy.
Actionable Insights for 2026:
- For Buyers: Don't feel pressured to upgrade every year. The current active user data shows that "older" models (2-3 years old) are the most common for a reason—they still work great.
- For Sellers/Resellers: The secondary market for iPhones is stronger than ever. Because the user base is so large, an iPhone 14 or 15 still holds significant trade-in value compared to almost any other tech device.
- For Privacy-Conscious Users: With the massive user base, Apple has doubled down on features like "App Tracking Transparency." If you're one of the 1.6 billion, make sure you've actually audited your privacy settings lately.
The sheer scale of how many people use an iPhone today is a testament to a very specific kind of brand gravity. Whether you love the "walled garden" or find it restrictive, there's no denying that 1.6 billion people have decided it's the place they want to be.
