I wear my fr955 to bed and then during the day till around 2pm. I take it off till bedtime.
now my body battery may be 55 when I take it off at 2. When I put it back on at 10 pm it shows a bb of 55 but within 10 minutes drops to say 30. Does this mean the watch assumes I am wearing the watch all day and figures it would go from 55 to 30 if I had been wearing it from 2 till 10?
