A Week of Battery. No Nightly Charging.
Most trackers die on you every other night and cannot go near the pool. This one runs up to 7 days on a charge, refills in about 2 hours, and is IP68 waterproof - so it stays on your wrist through workouts, showers and swims.

-
Up to 7 days of use — About 3-6 days of active use and roughly 15 days on standby.
-
2-hour fast charge — Snap on the magnetic charger and it is back to 100% in about two hours.
-
IP68 waterproof — Rated for swimming, not just rain and sweat.
-
Heart rate, sleep and blood oxygen — Real-time readings plus sleep phases, resting heart rate and average SpO2.
