Shared across both devices is a strong connectivity foundation: 5G, Wi-Fi 7, dual SIM, NFC, USB-C, GPS with Galileo, and an infrared sensor. For the overwhelming majority of daily connectivity needs, users of either phone will have access to the same modern standards.
The divergences, however, are pointed. The Xiaomi 17 pulls ahead on cellular throughput — its peak download speed of 10,000 Mbits/s dwarfs the Poco F7's 4,200 Mbits/s, a gap that matters when connected to advanced 5G networks capable of delivering those speeds. On the wired side, the Xiaomi 17's USB 3.2 enables fast data transfers and display output, while the Poco F7's USB 2.0 is a notable step back — practically limiting file transfer speeds and ruling out high-bandwidth use cases like connecting to an external display or fast storage. The Xiaomi 17 also includes a barometer absent from the Poco F7, useful for elevation-aware navigation and weather apps. The one counter-point is Bluetooth: the Poco F7 carries the newer Bluetooth 6.0 versus the Xiaomi 17's 5.4, which can bring improvements in connection precision and efficiency — though real-world gains depend heavily on peripheral support.
Taken together, the Xiaomi 17 wins this category. Its dramatically higher cellular download ceiling, significantly more capable USB standard, and additional barometer sensor outweigh the Poco F7's Bluetooth version advantage. The USB 2.0 limitation on the Poco F7 is particularly consequential for a modern flagship-tier device.
