Hi, Probably had the 13" MBP for about 3 weeks now. Battery quoted times are usually always way above what you actually get, I understand that part. I'm using Word, Internet, Emails, and not in a massive way, but what is the average on the new MBP 2011 models..? I calibrated when I got it, well what I take as calibrating anyway. Charged fully, left plugged in for 2 hours, then unplugged. This I think is where I need the help bit, I don't get the part after that. Am I supposed to leave it on till it dies permanently, or can I use it, turn off, use, turn off, till it dies. Leaving it on permanently it will go to sleep and then probably take forever to die if I'm not using it. Apple say don't let it go to dead, it's not good for machine, but as I've found out, you guys are more knowledgeable than they are, Already one of my questions has been answered by you lot whereas nobody at Apple knew what i was talking about. Am guessing the battery indicator times at top by battery depend on what you're doing at any given moment. It changes from 7hrs left, to 6, to 4 to 3 within minutes. Guess that's how it works? What should I get from battery. Even the iPhone at 100% stays there for at least a few till you are using it, This seems to go to 80% within half hour of word processing?
