Whenever you are not able to see the charging indicator do not panic and the solution is simple.
# Charge your Band for 10 to 30 minutes, do worry if there is no charging indicator.
# Remove from charging and wait about 10 seconds.
# Charge you Band again, now you will the the charging indicator start to turn-up again.
Reason being when you allow your Band to dry to 0 basically the Band doesn’t have any power to show the indicator, by allowing the Band battery to run again short charge is a must..
