[QUOTE="MacInWin, post: 1749350"] If Apple is saying that, it's pure BS. The physics and chemistry of LiIon batteries does NOT need to keep electrons moving, and using the battery off charger increases total cycles of the battery, which is a major factor in battery life overall. Once a month to recalibrate the circuits is for the reporting software, not the management software of the battery, which is why it's controversial. All LiIon batteries start to decay two years after manufacture, albeit slowly at first, and the more cycles you have on the battery the faster the roll off can be. However, the battery can be cycled so many times before the decay is really apparent that if you get a new system every 5 years or so, the battery should last nicely, unless you take it all the way to depletion every day. But leaving it on the mains power all day is not harmful, either. Here is a good article from a knowledgable battery and charger manufacturer: [url]http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries[/url] [/QUOTE]
