What’s Going on with Smartphones?

A state of the union look at the market for mobiles.

Looking at the IDC data on smartphone shipments (2014 to present), the pattern shows a peak in 2017.

Covid caused a contraction and recovery but since then the unit market has not reached pre-Covid levels. Moreover, the current memory supply crisis is expected to cause a dip unlike any of the previous ones.

IDC expects the market in 2026 to roughly 1.09 billion units and another 1.1% decline in 2027. This may be optimistic. Yearly volumes could drop below 1 billion.

The sub-$100 entry-level device tier remains permanently constrained or uneconomical, pushing average selling prices higher. Emerging markets will fall the most. The Middle East and Africa are forecast to drop roughly 23%, Central and Eastern Europe down 19%, and Asia-Pacific (excluding Japan and China) down 14%.

In the US, Counterpoint says that sub-$100 smartphone sales declined nearly 65% during Q2 2026 compared with the year-ago period. The rest of the market fell by 45% as smaller manufacturers struggled to navigate component cost increases.

US Q2 smartphone market update:
Overall: -5%
Top 4 OEMs Apple, Samsung, Motorola, Google: -4%
All others: -45%
Prepaid: -11%
Sub $100: -64%
Apple reported N. American sales +11%.

Yet the number of smartphone users is not decreasing. There are approximately 5.78 billion unique smartphone users worldwide, accounting for over 70% of the global population. Moreover, there are over 7.6 billion active smartphones in use globally. (1.3 phones per user.) According to data trackers like Counterpoint Research, the active installed base grows by low single digits annually.

The history and near future of these measures are shown below:

Note the confluence of two trends: the increase of users and devices in use and the decline in unit sales. I also pointed out in the graph that of the units sold a certain number must be going to new users (as long as new users is growing). The remaining units (shown in yellow) are replacement units. That means they are used to maintain the base which is shown as the dashed blue line.

But if the dashed line is increasing (from 4 to nearly 8 billion) and the replacement number is constant (about 1 billion) then the phones in use must be lasting longer.

Dividing the base by the replacement rate gives the implied device lifespan, shown below:

If the sales and base data is correct then the lifespan must have grown from below 4 years in 2016 to about 8 years in 2023. It has held steady since and may stay there through 2028.

Eight years is a much longer time frame for an average phone’s life than many may consider reasonable. No Android vendor supports their phones that long. However, Apple supports iPhones with major iOS software updates for about 5 to 7 years from their release date. They often provide critical security patches for an extra 1 to 2 years after a phone stops getting main iOS upgrades. This means Apple support lasts about 8 years.

To confirm this we should analyze at the iPhone separately from the global market in the same way: installed base, units sold and implied longevity.

I used IDC data for iPhone unit sales in the graphs on the left and my own estimates in the graphs on the right. The installed base is based on Apple released data and extrapolations.

Apart from an anomaly in 2021 due to the recovery from Covid, the average lifespan for the iPhone (blue lines in the bottom graphs) holds at 8.5 in my data and 9.4 in the IDC data.

There are two reasons I believe my estimates to be more likely correct. First, because they also align with the overall market data (red line, right bottom graph) and second, they align with the support that Apple grants.

One more thing.

IDC also offers estimates of Samsung and Xiaomi unit sales. I show these estimates below.

To remove the noise of seasonality, I provided twelve-month averages (solid lines). Note that their estimate for the iPhone (which is lower than mine) puts Apple ahead of Samsung since 2024.

Also note that the “Other” vendors combined are in a secular decline in volumes which will accelerate into the rest of 2026 and 2027. It’s unknown whether this trend will continue in the longer term.

So what are the takeaways from this state of market review? Where are Smartphones going?
