About Apple Pencil we're not going to say a lot, because it's an auxiliary device about which thousands of articles were written. It's a great toy especially for iPad owners.
Both Bluetooth headset (handsfree) and Apple Pencil, are equipped with their own batteries to give freedom of movement to the user and not to force the connection to iPhone or iPad through a data cable or charging. Compared to iPhone or iPad, we did not have an electronic display on the sub-devices that would show us the battery charge level. In most bluetooth headsets, we are voiced when the battery is low. Some Planteonics handsfree models also estimate the number of hours left until the battery is fully consumed. to Apple Pencil is a little difficult to announce when the battery is almost exhausted. It would be an idea to start writing alone "attention, you have to get it loaded!" :-)
And if we look more closely at iOS settings and options, we find that Apple Pencil even "notifies us" when the battery is almost empty. Or well ... iOS shows us the percentage of battery power for all devices connected via Bluetooth to iPhone or iPad.
