Series nine 45mm. Two workouts everything on, always on display turned off.
I started testing my new Ultra 2 at 2am on Friday morning, 100% full charge. Not charging it at all.
It’s now almost 11am, and I’m still at 53%. Over a day and not even half depleted, this is crazy.
My Series 8 would need to get charged up to high 90s % before work. By 4:30 that afternoon would be down in the low 70s or as low as mid 60s.
