I bought a 17" unibody macbook pro 2 weeks ago and now it has 3 battery cycles and health is at 98%. My battery doesn't seem to last as long as Apple said it would. I'm only using it on half brightness, wifi on, bluetooth off, 9600M from when I opened my laptop 30 minutes ago I had 59% and now I have 41% All I've done in the 30 minutes is browser a little on the web and about 10 minutes of photoshop work. Question: is my battery health suppose to go down to 98% after only 3 cycles? and why is my battery dying so fast?
