Fitbit will not hold charge more then 8 hrs.

Hi

if its not holding a charge it is mostly the battery that's the issue but the Fitbit sense is a fairly new device so if its under warranty I would see what they say about it

here's guide on how to save battery by adjusting settings

there is a chance that It just needs a update as iv seen a lot of people having this issue when I had a look for a guide

I have had a look for battery replacement guides and there aren't any ,probably due to how new it is

if you have any more questions please ask

hopefully this helps

Thanks:-)
