I am using a Charge 2 but it seems to not accurately record my sleep. When I sleep for say 5 hours it only records just under 2 and seems to think I woke up 2 hours before I did. This has happened a few days now. What causes it and how can I fix it?
Best AnswerI used to face this either. I've been using fitbit one for sleep tracking but there was wrong data. Amazon fitbit one specifications http://amazon.manymanuals.com/sport-watches/fitbit-one/specifications-13561 helped me to understand how to set settings correctly without getting additional problem in futher usage.
