I recently bought an iPad Pro and Gen 2 pencil. I have noticed that if the pencil is not attached to the iPad and just sitting there it looses roughly 2% of its charge per hour. Is that due to BT trying to connect? Or does the pencil battery just work that way?
There are times and places I don't want to take the pencil. And since it has a LiON battery subject to the same charge/discharge limitations as any other, I don't want to draining much below 50% before recharging. I am guessing I'll have to unpair the pencil ay such times.
You can drain the Apple Pencil down to 10%, if you so choose.
You will need to disconnect the Pencil from Bluetooth to keep the Pencil from draining faster on Bluetooth.
FYI and something Apple never divulges 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!
You need to keep your Apple Pencil charged 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!
I discovered something interesting. A couple times this week I left my pencil at home while I was out of the house all day with my iPad. When I got back I hooked up the pencil and it indicated 100% charge. That would seem to imply that if the pencil can't connect to the iPad then it shuts down. In that case the battery would only very slowly drain, as all LiON batteries will over time.
In the OP I had the battery sitting on a table near the iPad for several hours. So its was mated to the iPad, and ver such alive while just sitting there. Even if doing nothing the radio link will radiate away power.
Hello,
Here is something to consider, Apple Pencil is essentially a tiny computer which is constantly powered on and communicating with iPad which depletes the battery by a small percent.
Well of course it is a computer. And a pretty sporty one at that. I had assumed that when it wasn't mated with the mother ship it would go into a suspense state to save power. My bad.
No.
Unless you disconnect the Bluetooth pairing of the Pencil when not using the Pencil, the Pencil will always be active, ready to go.
