Smartwatches with Bluetooth v5.0

Bluetooth v5.0

— reliable BLE foundation with increased range and bandwidth compared to 4.2, ensuring more stable notifications and more battery-efficient synchronization of steps, heart rate, and sleep. In typical scenarios, the watch quickly re-establishes connection after disconnection and less frequently "loses" control of music or calls, remaining fully compatible with older phones. In terms of capabilities, it is a confident "work standard": it doesn't include advanced features of new releases like EATT/LE Audio (5.2) or precise positioning Direction Finding (5.1), but for everyday use, it provides predictable connectivity, good range, and normal autonomy.
