Odd. Since pairing the Apple Watch with my iPhone, I've noticed the battery usage times go way up. Yesterday, it ended at nine and a half hours whereas I'd normally get around eight on the 6 Plus. Today I only used my iPhone for under an hour and have yet to even take the Watch off the charger yet my battery life usage is at 4 hours at 87% battery. Is the battery life usage counting continuous Watch connectivity as usage?
