I am just curious how people's MBA Late 2010's are doing battery-wise since installing Mountain Lion? I installed mine, and everything runs smoothly, but I'm actually losing almost an hour of battery life now, which is really disappointing, almost to the point where I may be switching back to Snow Leopard. I didn't do a "clean install", so I don't know if that actually affects anything or not, but the battery life, which is the best thing about the Late 2010's, has dropped. I only have 30 cycles in 6 weeks on my 2010, so I'm quite surprised. Anyone else experiencing this much drop?
