I have a white macbook, the machine is great and I'm especially happy with battery. I'm looking at the meter now and it says I have 5:30 remaining, excellent. Not many machines can compete with that. The problem begins when I browse to a flash video website. Youtube, BBC iplayer etc. I know and expect this will drain the battery faster than visiting macrumours. However I do not expect my cpu usage to sky rocket. The fans to begin working overtime to prevent the machine from melting and my estimate battery time to drop to 1:00 from over 5. Does everyone else have this problem? Are some browsers better than than others for preventing this? Or is it all down to adobe and there atrocious video implementation.
