Lithium Ion batteries see a reduction in the charge capacity each time they go through a full cycle. Think of it like carbon paper - each time you use it, its ability to create another copy of something is reduced and the quality of the copy is lower. | |
| Feb 1, 2011 at 13:20 | comment | added | ScottCher | Lithium Ion batteries have a lifecycle measured in # of "full" charge cycles. Each full cycle reduces the total charge the battery can hold by a miniscule amount. A full cycle isn't the same thing as a full discharge and recharge (though that does count as a full cycle and is bad for lithium ion batteries to do often). A full cycle is counted as each time an amount of charge equal to the capacity of the battery is used up - in other words, if you use 10% and then charge and do that 10 times, that's a full cycle and is roughly equivalent to a full discharge (though not bad for the battery) | |
| Oct 10, 2009 at 13:49 | comment | added | Arjan | I really don't understand Apple's idea of cycles. I doubt the battery will be affected by whatever the chip on the battery thinks is a cycle... Or is Apple trying to say that the way of charging is really different when it gets to another cycle? | |
