I take my watch off at night, put it on the standard charger. I started noticing that when i took it off of the charger that the green 'pulse' LEDs were on, and the "activity in progress" little icon was at the top of the screen. (green running man). Move and Exercise goals (which are set quite low) would then get quickly met. I've found that if I look at the watch before taking it off the charger, the fitness activity is already running... One evening I left the watch off of the charger, and woke up to find the room bathed in green light... When I go into the activity app, there is no activity in progress... I'm running the latest OS on watch and phone. Have also tried deleting the pairing, and doing a full reset on the watch. The only way i have found to stop it is to start a proper activity and then cease the activity after it has recorded some movement, and then it shows no activity in progress. Each morning I have to do this, which is a pain. Can't see anyone else reporting this... anyone have any ideas?
