One thing that's often overlooked is that the first few discharge/charge cycles should be appropriate for the sort of battery it is, in order to condition it.
Apple staff told you that ? Really ? Hmmm.......
OSFO,
ENOUGH of your stupid Apple bashing !
You know very well that the sort of batteries found in Apple (and many other manufacturers) devices does not need discharge/charge cycles !
The advice is to work on a top-up charge basis !
All you need to do is read the manuals for the devices if you don't wish to believe what people tell you.
The whole discharge/recharge "conditioning" thing is from the old Nicad era and is no longer applicable in this day and age of modern battery technology !
