So i've read through this forum looking for a fix and I've tried everything including factory resetm battery is still draining really fast. This literally just started happening since Tuesday and I can't figure out why.
Unfortunately there is a problem with battery life on some models which Fitbit fail to acknowledge and worryingly, in my experience, remove any comments on this matter on the community forum. From being a Fitbit advocate I am now happy with a rival product.
