Xloop battery and charging: how long it lasts and how to charge it
Xloop lasts 5 to 10 days on one charge and recharges magnetically in about an hour.
Xloop is designed so you rarely think about charging. Here is what to expect from the battery.
Battery life
Xloop has a 16 mAh battery and lasts **5 to 10 days** on a single charge. How long it lasts depends on how you use it and how often the ring takes measurements.
Charging
Xloop charges magnetically. A full charge takes **about one hour**. Place the ring on its charger, and the magnets hold it in position.
Tips for longer battery life
- Charge while you shower or get ready, so you don't miss a night of sleep tracking.
- Keep the Alexi app updated.
- Top up before travelling.
Water resistance
Xloop is rated 5 ATM and IP68, so you can wear it while washing your hands or in the rain. Dry it before charging.
