The connectivity foundation is virtually identical: both phones support 5G, Wi-Fi 7, USB 3.2 Type-C, NFC, and an identical set of sensors including GPS, barometer, gyroscope, and Galileo. Cellular speeds are matched too, so neither has an edge in raw network throughput.
The meaningful divergences cut in different directions for different users. The Xperia 1 VII steps ahead with Bluetooth 6.0 versus the S25's 5.4 — the newer version brings improved connection stability, better multi-device handling, and lower latency, which matters for wireless audio and peripherals. The Xperia also includes an external memory card slot, a feature the S25 drops entirely — a significant practical advantage for users who want to expand storage affordably or transfer files physically. The Galaxy S25 counters with dual SIM support — 2 SIM + 2 eSIM slots versus the Xperia's single physical SIM and single eSIM — a meaningful benefit for frequent travelers or anyone managing personal and work lines simultaneously. The S25 also supports ANT+, a protocol used by fitness equipment and sports accessories, which the Xperia omits.
This category is a genuine split depending on priorities. For storage flexibility and future-proof Bluetooth, the Xperia 1 VII has the edge; for dual-SIM flexibility and fitness accessory compatibility, the Galaxy S25 wins. Overall, the Xperia's advantages — expandable storage and newer Bluetooth — are likely to benefit a broader range of users, giving it a slight overall edge in this group.
