After updating software has anyone noted an exceptional battery life improvement? Now, I did just get my Nike Watch 2 last Sunday. But after updating software my battery life greatly changed. Before update: Out of the box I had a 100% battery. During use I would wear the watch all day and wear it over night with a sleep tracker. When I woke I would have 45-55% charge, charge to 100% between 6-7am and go again. Every day was the same, very consistent on battery life After the update I am at 31 hours and have 55% battery .. I find that a abnormal adjustment. My day to day usage has not changed and I have made no setting adjustments.
