I've had this. Lily for exactly 385 days and the last week or so it began having this problem where it would shut down like the battery was dead. When I could I would go plug it in and see that the battery was there. At times I would take it off and let it play out the rest of the battery or until it shut down on me again. Then I let it fully recharge out to see if that would make a difference, it has not. I can't use the watch without it being plugged in. It is no good. Please assist. This was more expensive than other alternatives but I thought Garmin was a good product and was willing to pay it. Show me I was right.
