Had an Apple Watch since launch. Battery used to last me 1.5 days easily (usually charge overnight). Now after the recent update it's fully depleted by 4pm each day. My iPhone / watch usage hasn't changed in the slightest. Something has borked the watch and my only thought is that it is the update, somehow. Or is this simply some planned obsolescence on apple's part considering rumours of a new model in March?! Anyone have any shared experiences or tips?
