Connectivity is another closely contested category, with both phones covering the essentials identically: 5G, dual SIM, NFC, USB Type-C, Bluetooth 5.2, fingerprint scanner, GPS with Galileo support, infrared sensor, gyroscope, and accelerometer. For the vast majority of everyday use cases, these two phones are functionally equivalent in how they connect to the world around them.
The meaningful divergences are in Wi-Fi and cellular throughput. The Honor X9d 5G supports Wi-Fi 6 (802.11ax), while the Tecno Camon 40 Pro tops out at Wi-Fi 5 (802.11ac). Wi-Fi 6 delivers better performance in congested environments — busy offices, airports, or homes with many connected devices — along with improved power efficiency. That is a tangible long-term advantage for the Honor. Flipping the advantage, the Tecno leads on cellular speeds: it posts 3270 Mbits/s symmetrically for both download and upload, against the Honor's 2900 Mbits/s download and a notably lower 1600 Mbits/s upload. The Tecno's upload speed advantage is particularly relevant for users who frequently send large files, stream live video, or rely on cloud backups over mobile data.
This group ends in a nuanced split. The Honor X9d edges ahead for home and office users who will benefit from Wi-Fi 6 on a modern router. The Tecno Camon 40 Pro holds the advantage for mobile-first users who depend heavily on cellular uploads. Neither phone has a sweeping overall lead — the right choice comes down to which connectivity scenario matters more to the individual user.
