Apple Watch showing spurious EXTRA activity
my Apple Watch 3 has started to show extra activity. This morning I went for a 1.07 mile walk, where I had used the Outdoor Walk function. But the Activity app noted that walk and said I had put in over 5,000 steps and 2.25 miles total (I should have taken a screenshot).
i know I didn’t walk a mile inside my house that AM, because I had been sitting at my computer.
a few days ago, it had done something similar, saying that I had travelled 3 miles when I only ran 1 mile.
i calibrated my watch at the beginning, but could these extra miles be a calibration error? I have had this watch about 1 year (a warranty replacement after first one broke). I also noticed the battery barely makes it through 15 hours of wearing.
