My MacBook 12" 2016 model has the same issue. This isn't only a MacBook Pro issue. For more than a year my laptop sometimes won't go past 1% for hours and when it does go past 1% and hit 100%, it immediately shuts off as soon as the power cable is taken off. Dropped $1,400.00 for a laptop whose battery went bust after almost 4 years. My iPhone 7 Plus was purchased during the same year and even though the battery life has depreciated, it still charges and discharges perfectly fine.
