I've calibrated, shut off bluetooth, did cops reset, etc. and I'm not sure what else to do. I ran the useless smc update and now the fan is going nuts all the time. With the screen on it's brightest and wifi on, I'm getting about 1.5 hours of battery life. I'm not a picky user, but this is really unacceptable. I'm flying tomorrow and honestly think I can watch a movie more comfortably with my iphone than with my MBA on 1/10th brightness. The odd thing is that system profiler is showing my battery capacity at 5000, yet I'm getting my worst battery time since I purchased the MBA. I've brought it into apple and since the capacity checks out alright, they claim nothing can be done. Between the shuttering video, heat issues, poor battery length, poor battery charge times, I'm really getting a bit frustrated. Any advice?
