It is possible that, because of the pandemic, that Apple Stores may have old,,new stock of Apple Pencils that have been sitting around for some time and not being able to be charged up, being in storsge and sealed up, may have lost all of there battery charge for some extended period of time and the batteries in these stored Pencils have died/failed.
You cannot store Apple Pencils for any prolonged period of time and NOT keep them charged up to some level.
If your Apple Pencil/s sat around unused or unopened and not kept charged up for more than a few weeks, or so, OR
LONGER, then the battery in Apple Pencils may have comoletely drained, failed and the Pencil is fully dead.
And it looks like some things about the Apple Pencil have NOT changed in the new version 2 model, either.
FYI and something Apple will never, EVER divulge to it potential iPad Pro/Apple Pencil customers/users unless the potential customer/user is smart enough to ask about,
Due to the “always on and active/standby” nature of the Apple Pencil and, also, due to its very tiny rechargeable Li-
ion battery ( smaller than the eraser head on a REAL wooden pencil ), the Apple Pencil needs to be constantly charged up to some significant charge level ALL THE TIME, even when not using the Pencil for prolonged periods of time.
The Apple Pencil needs to be kept charged to a minimum of 5-10% all the time.
If the Apple Pencil battery is allowed to drain down to 0% and allowed to stay in that flat condition for more than a few weeks, or so, OR EVEN LONGER, that very tiny little Li-ion battery is too small to keep at a 0% state for a long period of time and it will fail and the Apple Pencil will be dead and you may have to “pop” for another $99 Apple Pencil, once again!
Apple Pencils need to be kept charged up all the time, even if it is only to 10%-15% charge. It must keep some charge level in that tiny Lithium-ion battery at all times!
