I lost the charger for my watch and it was off for a couple of weeks while I waited for a new one to arrive in the mail. Since it has been back on the past week or two since the charger has arrived, I've been having new problems with it. Yesterday, I was sick and stayed in bed all day and my watch showed that I had over 50,000 steps and over 22 miles. It did not reset over night and now it says I'm up to 68,000 steps and over 30 miles. I've known it to be slightly off in the past, but not to this extreme. Any ideas on how to correct this issue?
