saw I am not the only one with facer draining battery. was not sure so did a test
did rest my watch completely
used it for 5 days without facer, all fine, stayed 2 days on without need for charging
then installed facer, battery consumption was allright during the day, went to bed with 60% of battery
woke up 7 hours laters with watch dead,
something is going on at night… this is painfull
