Wireless connectivity is where the G86 Power pulls meaningfully ahead. It supports Wi-Fi 6 (802.11ax) in addition to Wi-Fi 4 and 5, while the G57 Power tops out at Wi-Fi 5. Wi-Fi 6 delivers lower latency, better performance in congested environments with many connected devices, and improved efficiency — benefits that are increasingly relevant as home networks grow denser. Bluetooth tells a similar story: the G86 runs Bluetooth 5.3 versus the G57's 5.1, offering modestly improved connection stability and energy efficiency for wireless peripherals and audio devices.
The cellular speed gap is also notable. The G86 achieves symmetrical speeds of 3270 Mbits/s for both download and upload, while the G57 reaches 2900 Mbits/s down but only 1500 Mbits/s up. That upload disparity matters practically for anyone who frequently sends large files, live-streams, or makes video calls on mobile data — the G86 handles outgoing data at more than double the G57's ceiling. Additionally, the G86 includes an external memory card slot, a feature the G57 omits entirely, offering a straightforward and affordable way to expand storage beyond the built-in 512GB.
The two phones share an otherwise identical connectivity foundation — 5G, NFC, USB Type-C, the same sensor suite, and equivalent SIM configurations. But the cumulative advantage of Wi-Fi 6, newer Bluetooth, faster upload speeds, and expandable storage gives the Moto G86 Power a clear and well-rounded edge in this category, particularly for users who demand the most from their wireless connections.
