[QUOTE="iLaw, post: 755674, member: 56662"] Well from personal experience, My battery's health went down to 50% in a matter of 6 months when I left it plugged in all the time (I used to use my laptop as a portable desktop i.e. Always closed, using DVI out and bluetooth keyboard and mouse). 150 charge cycles and it was at 50% health. After getting results like this, my battery was replaced under AppleCare/Warranty because it was not performing to specifications. Now, with my new battery, I let it drain to 40-50% and plug it back in, doing a calibration every 1st of the month. I'm at 170 charge cycles and my battery is at 91% health. My Advice: don't leave it charging all the time. [url=http://www.apple.com/batteries/notebooks.html]Even Apple says[/url] that the "ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge"; which implies that the batteries were intended to be drained and then recharged to "keep the juices flowing".
