Cellular connectivity is perhaps the starkest dividing line in this category. The Honor X9d 5G supports 5G with download speeds up to 2900 Mbps, while the Nova 14i is limited to 4G with a maximum of 390 Mbps down and 150 Mbps up. That is not a marginal gap — it is a fundamentally different tier of mobile connectivity. For users in areas with 5G coverage, the X9d can deliver dramatically faster downloads, lower latency streaming, and greater readiness as 5G networks mature and expand.
Wi-Fi tells a similar story. The X9d adds Wi-Fi 6 (802.11ax) to its supported standards, a generation ahead of the Nova 14i which tops out at Wi-Fi 5. Wi-Fi 6 offers improved throughput, better performance in congested environments with many connected devices, and lower latency — tangible benefits in busy households or offices. The X9d also runs Bluetooth 5.2 versus the Nova 14i's Bluetooth 5.0, a minor but real improvement in connection stability and efficiency. Additionally, the X9d includes a gyroscope and an infrared sensor — the gyroscope enabling more accurate motion-based features and gaming controls, the IR blaster allowing the phone to act as a remote control for compatible devices. The Nova 14i lacks both.
Shared features — dual SIM, USB Type-C, NFC, GPS, compass, accelerometer, and fingerprint scanner — provide a solid common baseline. But the X9d's advantages in 5G, Wi-Fi 6, and additional sensors add up to a comprehensive connectivity lead. The Honor X9d 5G wins this category clearly, and by a considerable margin on the most impactful specs.
