Recently my band has not been able to make it through a day, either alerting me it is low or dying while sleep tracking. I had my original band replaced about a month ago and it was working fine, but not long after my 925 died and I paired it with my Android work phone and later a replacement android phone. I managed to repair my lumia and went back to using it with that device, but since then the band will rarely last a day where I used to get a day and then some, having around 40-50% left in the morning after tracking my sleep and only topping it to 80% the day before. I am trying factory resetting it to pair it to the lumia fresh, but I'm not sure if it will make a difference. Does anyone have any suggestions?
