Currently running beta 11 on my new iPad Pro 10.5". Battery life sucks so far. Slight improvement from beta 2 but still overall sucks. I've never run iOS 10 on it cause I immediately restored from backup which was beta iOS 11, so I have no experience with the iPad Pro and a release candidate OS. Is there any possibility that 120hz refresh rate consumes a significant amount of more battery power than 60hz?
