42 mm Apple Watch Sport, had it for a month on Thursday. Battery life seems very inconsistent. I took it off the charger this morning at 7:30 AM. It's almost 3:00 PM now and the percentage is at 69%. Does this sound normal? I've been comparing battery with my dad's stainless 42 mm Apple Watch and his watch always seems to have a higher percentage than mine, even though he often pulls his off the charger before I do. I know usage plays a role here but is usage is usually very close to mine and his seems to get better battery life. I've restored the watch a few times (by unpairing and repairing) and it seems to fix it for a few days but now it's back to draining what seems like very quickly. Just wanting to get a feel for whether or not this sounds unusual before I call Apple and see what's up. Anyone?
