I bought a new Venu on Friday. I put it on and it it said my body battery was at 60. It went down to about 25, and was 80 the next morning (Saturday) when I woke up. It went down to 10 overnight. The next sleep put it up to 30.(Sunday) By about 2pm it was down to 5 - and has stayed at 5 ever since. Sleep doesn't seem to have affected the number at all.
It is now stuck on 5 - 24 hours later. Have had good sleep in the meantime (even got a badge for my sleeping).
How do I get this to work properly please?
