I've spent years tracking iPhone sales data—from Apple's earnings calls to third-party reports like Counterpoint and IDC. And honestly, the numbers tell a story that surprises most people. Not every iPhone is a blockbuster. Some models flopped (relatively speaking), while others became cultural phenomena. In this post, I'll break down the sales numbers by model, share the data in a clear table, and explain why certain iPhones dominated while others struggled.

Total Sales Overview: How iPhone Sales Have Evolved

Since the first iPhone launched in 2007, Apple has sold over 2.3 billion iPhones (as of early 2025). But the distribution isn't even. The iPhone 6 series alone accounts for about 10% of all iPhones ever sold—that's insane. In contrast, the iPhone X, despite being revolutionary, didn't sell as many units as its successors. Let's look at the data.

The Top 5 Best-Selling iPhones (All Time)

Based on cumulative sales (including all variations of the base model, Plus, Pro, etc.), here are the top 5:

  1. iPhone 6 / 6 Plus – ~222 million units
  2. iPhone 11 Series – ~159 million units
  3. iPhone 13 Series – ~150 million units
  4. iPhone 6s / 6s Plus – ~125 million units
  5. iPhone 7 / 7 Plus – ~100 million units

The iPhone 6's massive success is often attributed to the larger screen—Apple finally caught up to the phablet trend. I remember when it launched; people lined up for days. The iPhone 11 and 13 benefited from aggressive pricing and strong camera upgrades.

Complete Sales Numbers Table by Model

Below is a comprehensive table of iPhone sales numbers by model (estimated, in millions of units). These figures are compiled from Apple's official quarterly reports, Counterpoint Research, and IDC. I've cross-checked multiple sources to ensure accuracy.

Note: Sales numbers for models released after 2022 are still accumulating. The table shows data as of early 2025. I'll update this article when new figures are released.

Why Some Models Outsold Others

Looking at the numbers, there are clear patterns. Here are my observations after years of tracking this data:

  • Screen size jumps drive massive upgrades. The iPhone 6 was the first with a 4.7-inch screen (and 5.5-inch Plus), which caused a tsunami of upgrades. Similarly, the iPhone 12's shift to 5G spurred upgrades.
  • Budget models cannibalize but also expand the market. The iPhone XR and iPhone 11 were cheaper than the Pros and sold incredibly well. But the iPhone SE never reached the same heights because the design felt dated.
  • Pro models have a ceiling. The Pro Max variants often sell better than the smaller Pro, but the combined Pro lineup rarely exceeds the base model in volume. For example, iPhone 13 series: base + mini ~150M vs Pros ~55M. Most people don't need the most expensive camera.
  • Camera improvements matter less over time. Once cameras became “good enough,” the primary motivator shifted to battery life, screen quality, and ecosystem lock-in.

What About Recent Models? iPhone 14 & 15

The iPhone 14 series saw a decline compared to the iPhone 13—many reviewers called it a “minor update.” Sales of the iPhone 14 base model were sluggish, but the Pro models picked up due to the Dynamic Island and 48MP camera. The iPhone 15 series reversed the trend slightly with USB-C and the titanium Pro models. I personally upgraded from an iPhone 13 Pro to an iPhone 15 Pro Max, and the weight reduction is noticeable. Based on early data, the iPhone 15 Pro Max is outselling the smaller Pro by a 2:1 ratio—a shift from previous years.

Frequently Asked Questions

Why did the iPhone 6 sell almost twice as many units as the iPhone 6s?
The iPhone 6 was a design revolution—Apple finally offered large screens that Android users had enjoyed for years. The 6s, while faster and with 3D Touch, was an iterative upgrade. Many people who bought the 6 didn't see a reason to upgrade after just one year. Plus, the 6s launched at the same price, but the market was more saturated.
Is the iPhone 11 really the second best-selling iPhone ever?
Yes, according to multiple analysts. The iPhone 11 hit a sweet spot: great camera, excellent battery life, and a relatively affordable price ($699 at launch). It also benefitted from being the default iPhone during the early pandemic, when people were upgrading for remote work and video calls. The Pro models sold well too, but the base 11 was the workhorse.
How do iPhone sales numbers by model affect resale value?
Massive sales typically mean a flood of used units later, which can depress resale prices. For example, the iPhone 6 is now worth almost nothing because there are so many in circulation. On the other hand, low-selling models like the iPhone X (63M) hold value slightly better because they're rarer. But other factors like repairability and iOS support matter more. If you want high resale value, buy a Pro Max model—they tend to depreciate slower because of the premium camera hardware.
Does Apple release official sales numbers by model?
No, Apple stopped reporting unit sales by product line in 2018. They only give revenue numbers. The model-level data we have comes from third-party research firms like Counterpoint, IDC, and Strategy Analytics, which estimate based on supply chain checks, carrier data, and surveys. The numbers in this article are the most reliable aggregates I could find. I always cross-check at least two sources.
Will the iPhone 15 eventually surpass the iPhone 11 in sales?
Probably not. The iPhone 15 series launched in a maturing smartphone market with longer upgrade cycles. As of early 2025, combined sales of the iPhone 15 family are around 145M units (including base, Plus, Pro, Pro Max). The iPhone 11 reached 159M in its lifetime and is still selling through budget channels. I estimate the 15 will finish around 160-170M if Apple extends its lifecycle, but it won't beat the iPhone 6's record.
