Connectivity is where the trade-offs between these two phones get genuinely interesting. The Lava Blaze Amoled 2 supports 5G, while the Realme C71 is limited to 4G LTE — a distinction that is directly reflected in their cellular speeds: the Lava reaches up to 2770 Mbps download versus the Realme's 300 Mbps. For users in areas with 5G coverage, this means dramatically faster mobile data, lower latency, and better future-proofing as 5G networks continue to expand. The Realme's 4G ceiling, by contrast, is adequate today but will age less gracefully.
The Realme C71 counters with NFC, which the Lava lacks entirely. NFC enables contactless payments and quick device pairing — a meaningful convenience for users who rely on mobile wallets. The Lava edges ahead on Bluetooth with version 5.3 versus 5.2, a minor difference, and also includes a gyroscope that the Realme omits — relevant for gaming, navigation apps, and augmented reality experiences. Both share the same Wi-Fi standards, dual SIM support, expandable storage, USB-C 2.0, fingerprint scanner, GPS, and Galileo.
This category does not have a single clean winner — it depends on user priorities. The Lava Blaze Amoled 2 has the broader connectivity advantage with 5G and a gyroscope, while the Realme C71 appeals to users who value NFC for contactless payments. On balance, 5G is the more impactful differentiator for most users, giving the Lava a slight overall edge here.
