Smart watches and fitness bracelets with Bluetooth v5.3

Bluetooth v5.3

— in watches and fitness trackers, Bluetooth 5.3 is "bringing order" to the already familiar BLE: faster and more reliable reconnection after disconnection, smoother flow of notifications and sensors in the gym, fewer false disconnections near other gadgets. Improved organization of advertising packets and flexible scheduling of active/sleep intervals help save power without losing the responsiveness of the player remote, alarms, and incoming calls. Compared to 5.2, it is a small but noticeable step in convenience, while 5.4 mainly adds infrastructural elements like advanced broadcasting and advertising encryption, which are more important for the ecosystem than the basic "watch-phone" scenario. In practice, this provides users with a more predictable connection throughout the day and increased battery life, especially if the watch is always connected and syncing workouts.
