Do I need to charge the battery?Updated a year ago

No! We did not want to burden you with yet another accessory you have to remember to charge. Our product is designed to have a long-lasting battery life so you never have to worry about charging it. We guarantee one year but it can be up to two years depending on usage. The app will notify you once your battery is running low if you enabled notifications. Replacement charms are discounted to $99 (less than $10 per month).
