iPhone Air Outpaces Galaxy S25 Edge in Slim Phone Market Share
In 2025, Apple and Samsung both launched ultra-slim flagship smartphones—the iPhone Air and Galaxy S25 Edge—testing consumer appetite for thinner designs. Recent data suggests that, despite Samsung's earlier market entry, the iPhone Air has gained stronger traction in key global markets.
Market Performance in Key Regions
Data from Q4 2025, based on Speedtest samples, provides insight into the relative adoption of these devices. The iPhone Air demonstrated a notable lead in several regions, including Samsung's home territory.
South Korea: The iPhone Air captured an 11.2% share of devices using the service, while the Galaxy S25 Edge followed with 8.7%.
United States: The gap widened, with the iPhone Air at 6.8% and the Galaxy S25 Edge at 2.4%—a nearly three-to-one advantage for Apple.
In other markets like the United Kingdom, the Galaxy S25 Edge showed minimal penetration, below 1%, while the iPhone Air maintained a stronger presence. This pattern indicates that, overall, fewer Galaxy S25 Edge devices were active on the network compared to the iPhone Air across the measured regions.
Implications for the Slim Phone Segment
The data, while not a direct sales figure, suggests that Apple may have sold more units of the iPhone Air than Samsung did of the Galaxy S25 Edge, even in South Korea. This outcome highlights the strength of Apple's brand loyalty and premium positioning, which likely contributed to the iPhone Air's performance despite competitive offerings.
Reports indicate that both companies have since reassessed the market for super-slim flagships, with potential successors to these models possibly delayed or reconsidered for 2026. The trend among early adopters appears to have favored Apple's entry, raising questions about the long-term viability of this niche segment for Android manufacturers.
Conclusion
The iPhone Air's lead in usage share over the Galaxy S25 Edge underscores the challenges Samsung faces in competing within the premium slim phone category, even on its home turf. While the Galaxy S25 Edge was noted for its technical merits, Apple's ecosystem and customer base provided a decisive edge in market penetration. As the industry evaluates the future of ultra-slim designs, this data serves as a critical reference point for consumer preference and brand dynamics in the high-end smartphone market.
