Being disabled veteran I walk slow but still walk every morning. I leave my phone at home and play music through Bluetooth headphones. I walk 1.5 hours for a total of 5 miles (told you I was slow). My battery at the end is down to about 59%. I am not sure if this is normal but I have to charge it by 7:30 every night.
Not sure if I can get better battery life but would love to keep wearing it till bedtime. I have cut many notifications from coming through and BAR is off.
