[QUOTE="MacInWin, post: 1905563, member: 396914"] What changed is that Apple learned about Lithium batteries. Originally, they gave out advice that was appropriate for NiCad (conditioning), but that cycle is hard on Lithium batteries. The original advice was to discharge the batteries fully every time. Then it changed to monthly, to "calibrate" the battery circuits, not the battery. But, as I said, how long a battery lasts doesn't depend as much on the level in the battery as it does on how it is used. So, instead of trying to estimate battery time they started showing (and emphasizing) battery percentage left. Now they don't even show any time estimate at all, just a percentage. So, what changed is that Apple got smarter since 2014. The chemistry is the same. OWC's video is out of date and wrong. [/QUOTE]
