I charge my watch every night I put it on in the morning it's usually at around 97 to 98% I put it back on the charger till it gets to a hundred pct, I go to go to work Midway through the day the phone turns off and I cannot turn it back on when I get back home I put it on the charger and it says it's still at 72% why does my phone shut off Midway through the day when it still has battery life and why can't I turn it back on when it still has battery life, this happens on a daily basis it shuts off and I cannot turn it back on or the battery will run out for hours into the day and when I get home it's at 17% after 4 hours
