Connectivity is where these two phones trade punches rather than one decisively outclassing the other. The Nova Y63 supports both Wi-Fi 4 and Wi-Fi 5, giving it access to faster, less congested wireless networks — a meaningful everyday advantage for streaming and downloads at home. The Y73, by contrast, is limited to Wi-Fi 4 only, which caps its wireless throughput. Somewhat paradoxically, the Y73 posts a higher cellular download speed of 600 Mbps versus the Y63's 390 Mbps, so on a strong LTE connection the Y73 can pull data faster — but this advantage only applies when away from Wi-Fi.
The sensor loadout splits the two phones in different directions. The Y63 includes a gyroscope, which the Y73 lacks — a relevant omission for users who play motion-sensitive games or use augmented reality applications, as those features depend on gyroscopic input. The Y73 counters with an infrared sensor, absent on the Y63, which allows it to function as a universal remote control for TVs and other IR-compatible appliances — a niche but genuinely useful convenience feature. Bluetooth favors the Y73 marginally at version 5.1 versus 5.0, offering slightly improved connection accuracy, though the practical difference in daily use is minimal.
This category does not have a clean winner — it depends on the user's priorities. For better home Wi-Fi performance and gaming sensor support, the Y63 has the edge. For faster LTE speeds and the flexibility of an infrared remote, the Y73 pulls ahead. Shared fundamentals like NFC, dual SIM, USB-C, GPS, and fingerprint scanner mean neither phone is lacking in core connectivity.
