Had my watch since Feb, and it’s been fine till today. The watch was left on overnight with 28% power, this morning it was dead. Tried turning it on, no response. Connected it to the charger, no response. I was getting ready to start looking for a replacement when I thought “One more try”. I held the power button for about a minute, and the watch came back to life. connected it to the charger and it started receiving power. Seems ok at the moment, but it has dented my confidence in the product, and I’m just awaiting the day when it expires for good. Even though it’s still under warranty I don’t know if I’ll go down that road having heard others tales of woes.
