Review on 🔌 Enhanced Charging Cradle Dock for Samsung Galaxy Watch SM-R800/R810/R815 (42mm/46mm), Compatible Charger for Samsung Galaxy Watch - Not Suitable for Active Version by Victoria Smith

I'm a flight attendant so I wear my watch all day when I arrive at the hotel and check in the next day and it can only last 10 hours. I put my watch on the charger I bought to save my pocket too. I wake up and my watch isn't charged, maybe 10%! Heck, but when I wake up in the middle of the night, it's fully charged, I take it off, when I sleep all night, it's not fully charged. Please explain why this is happening. I need a watch but it's not charged. I'm screwed and so are the passengers if there's an emergency. Unlike my original charger, when fully charged it doesn't start to discharge like this one I bought.
