In reference to this, why does Apple think that constantly discharge/charging of a Lithium-ion batteries maintains maximum performance ? Even though the first few change/discharges cycles could increase it, the rest is not rquired. Apple just wants you to think that. Almost other manufactures who all say the same, those in the know, know that these batteries have protective circuitry to prevent such over-charging. Since Apple never mentions anything about protective circuity in their Lithium-ion batteries, this can only conclude that Apple want you to reach x number of cycles quicker, thus Apple gets more money because the battery will die quicker, thus need replacement sooner. Either that or Apple's battles doesn't have any protective circuitry, which would be dangerous. Even though all batteries die eventually, Lithium-ion isn't exactly old technology, i don't think Apple understands that. Or they do, just choose to keep it secret.
