Apple Pencil 2 draining iPad Pro battery

Has anyone else found that leaving their Apple Pencil 2 attached to their iPad Pro 11 overnight drains the battery anywhere from 15%-25%. I did a test of leaving the pencil attached over night and saw a 17% loss in the iPad battery. The pencil was fully charged when I left it connected overnight. So it really had nothing to charge on the pencil. Then I charged the iPad to 100% and left overnight without the pencil attached and the next morning the iPad battery was still at 100%.

Seems like the Apple Pencil 2 is constantly drawing power from the iPad Battery. Was just wondering if anyone else is seeing this behavior. Would like to keep the pencil attached so I know where it is but not if it keeps draining the battery.

iPad Pro 11-inch, Cellular, iOS 12.1

I have exactly the same problem.

After several experiments, I found that the iPad's battery won't be drained if I don't attach Apple Pencil 2 on my iPad pro (11 inch).

It is a clear proof that Apple Pencil keeps stealing battery from iPad.

And for your information, there is some energy loss when we talk about wireless charging, it is the cons of wireless charging tech itself, Apple product is no exception. That being said, when your iPad charges your Pencil, there is gonna be some percentage of battery lost during the process without going directly to the Pencil. Adding everything together, it is not hard to imagine the battery will drop so fast.

Short term solution would be finding a good dock or case for your Pencil, put it separately with your iPad. It worked for me.

Long term solution, I guess it is more of an Apple job, is simply not to charge Apple Pencil as long as the battery is not lower than a threshold, which could be exposed to the user. After separating my Pencil for a while, two or three days, I still have 92% battery in it. That said if iPad Pro doesn't automatically charges Apple Pencil before its battery goes lower than 80%, it could very likely save the day.

Of course, it is up to them to solve the problem.

To me, this gen iPad is good, but not perfect, it has a lot of flaws, this is just one of them you will have to bear with to enjoy your fullscreen experience, :)

Your very confidently-expressed explanation seems to make technical sense, logistically, though you seem to gloss-over perhaps the most obvious structural element of the issue -- i.e. what the Pencil could even be doing such that it would burn through that much of the iPad’s battery, by itself, while the iPad is otherwise dormant.. ?

You‘re making no indication that the iPad itself is doing anything, which I imagine you’ll double-back on, otherwise the question of HOW the little Pencil could possibly use that much wattage without literally melting itself, still remains..

Lastly, speaking properly - What exactly would you provide as backup sufficiently qualifying you to comment on what the Pencil “should” be doing or is “designed” to be doing, by any measure..?? Assuming you’re not the chief engineer overseeing Pencil development, and without any other substantive reference(s), that‘s nothing more than a personal opinion .. Perhaps it’s a valid one, maybe, but nonetheless inconsequential without backup.

Thanks,

MJA

It is a way, but a better way to solve it is through software, which Apple should have done.

It’s done for me... Via the Apple feed-back site

I have the same issue. The Apple pencil 2 is not always charging. At a certain point, even when attached to the ipad, it starts to drain. Any news on this?

After a reboot of my iPad yesterday, the pencil acts as before: draining sometimes, even when attached. Darn!

I leave the iPad Pro plugged in with the pencil attached. This evening my Pro is 100% charged. My pencil is at 76%. Charged..

Why not both 100%. This makes no sense at all.

This definitely helped for me, too. 2 percent drain per night with pencil attached instead of 10-20.
