Apple Pencil 2023 - was there warning in apple packaging about having to keep it charged?
Cannot remember any warning on or in packaging about the need to keep it charged or it would fail?

All devices with rechargeable batteries should be charged regularly to prevent damage - amd in this respect, an Apple Pencil is no different. Where the Pencil perhaps differs is that it's battery is tiny - and is therfore significantly more vulnerable to the damaging effects of deep discharge than other devices with much larger batteries.
As the Pencil does not have a physical off-switch - and effectively remains "active" at all times, it is generally recommended that a second generation Apple Pencil or Apple Pencil Pro is docked with the host iPad when not in use - as this ensures that the tiny internal battery is kept optimally charged when not in use. Charging only occur when the battery requires charge from the iPad, optimal charge being entirely automatic.
Keeping the Pencil separated from the iPad when unused risks allowing its battery to discharge; if allowed to remain in this state, the battery will suffer irreparable damage. When the battery fails, the only remedy is to replace the entire Pencil; the battery is not a serviceable item.
An otherwise healthy Apple Pencil will suffer no negative consequences from being docked with its host iPad for extended periods.
