Overview
- Ookla’s Speedtest report published Sunday shows the iPhone Air accounted for 6.8% of U.S. iPhone 17‑generation samples in Q4 2025, up from 2.9% for the iPhone 16 Plus a year earlier.
- The Air’s gains coincided with a drop in the iPhone 17 Pro’s share to 30.6% from 34.9%, while Pro Max held roughly flat, suggesting some buyers traded power features for a thinner design.
- Apple’s C1X modem in the Air delivered near‑parity 5G download speeds with Qualcomm’s X80 and beat it on responsiveness in 19 of 22 markets, which matters for real‑time apps like cloud tools and AI features.
- Upload performance remains a weak spot for the C1X, with Ookla measuring up to about a 32% deficit versus the X80 in some regions.
- Adoption is uneven internationally, reaching 11.2% in South Korea and notable shares in Japan, Sweden, and Singapore, and the Air produced roughly three times the U.S. Speedtest samples of Samsung’s Galaxy S25 Edge.
