Hello, I am running windows 7 on my new MacBook Air-- this is a requirement for my work, so can't be changed. I bought the MBA because it's a beautiful laptop, thin and light, great screen, and great keyboard. My battery life, however seems to be terrible, especially compared to statistics I have seen on other reviews/threads. At the moment, when I am unplugged, I have brightness at 30%, I have the hard drive set to sleep when not in use. I have bluetooth turned off and wifi on. I almost exclusively use the computer to work on google docs. So, turn on the computer, work for half an hour, in Chrome, either sending and receiving emails or writing in Google Docs. (I can't figure out if this qualifies as "light browsing", but based on my battery drain I would say it's not...) I have a plug-in to block flash, and haven't been running flash on any website since I started using the computer. Here are my statistics: Last night, typed (on the web) for half an hour and went from 100-80% battery. Put the computer to sleep for 9 hours, and when I woke the computer it was at 74% battery. Typed and checked email for forty minutes, went to 57% Woke the computer two hours later and was at 49% typed (on the web) for half an hour and was at 29% put the computer into hybernate, turned it on ten minutes later at was at 27% I've now been typing for about half an hour and I'm at 15%. I'm losing, roughly, 20% of my battery for each half hour of typing in a browser, with flash disabled. That means 2.5 hours of browsing. I need to get 4 hours if I'm going to keep the computer. I am really not interested in starting a long debate about whether it is or is not crazy to run windows on a mac. Please believe me, I have read all those threads, and considered my own situation, and would really love to use this computer as my traveling laptop, if I can get it to work. Can anyone think of why I would be losing my battery so fast? Any tweaks I could make? Thanks in advance.
