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 would LOVE a feature in iOS to turn off the charging of the pencil or only allow charging below a setup percentage. I want to be able to carry my pencil connected to the iPad, but NOT have it drain the battery all the time.

Quite a rude reply, we are all aware that the pencil drains the iPad to get its charge but surely when the pencil is fully charged and the pad is left on standby and neither are in use it shouldn’t drain 40% off the battery overnight. You complete fool, this is a design flaw obviously and a simple piece of IF THEN programming would solve the issue

One particularly annoying thing is that some iPad Pro cases have been designed to incorporate the Pencil, and I have bought one of those. I have now taken out my Pencil because it does seem to me that my new iPad Pro 11's battery drains faster than it should as I use it. And of course I need to start thinking about buying a case for my Pencil - Grrrrrr!

Also: stand-by is stand-by: once charged, the Pencil should not continue to drain the iPad's battery.

Perhaps Apple can find a technical solution to this. It could be very simple: include a timer in the firmware such that once the Pencil battery is fully charged, a switch cancels the charging link; up to six hours during daytime; up to twelve hours overnight. I'm no programmer but I'm confident this is feasable and simple to implement.

Hi,

I did not notice the discharge part of the IPad. However, I have been asking myself a similaire qestion. The one about the Pencil 2 battery lifespan. As we know keeping the device on the charger while it’s over 80% decreases the lifespan of the battery over time. I’ve decided to leave the pencil on the table next to the iPad - not clipped to the iPad just in case. I am sure that engineers working on this thought about this aspect however I am not sure what decision have been made regarding this. As earlier the battery quality decreases the higher the chance it will be replaced by the user. I would welcome the option to disable the charging manually.

It might be too late to suggest this considering you might already have a case for your iPad Pro, but just recently I got the ZUGU Case for my iPad Pro on Amazon (Keep in mind I am definitely not paid to advertise or anything like that, I am just a satisfied consumer who really appreciate a good product) and there are two options of where to put your Apple Pencil. On the side connected via magnets (the usual place where the Apple Pencil charges) and there is a little elastic pocket on the back the keeps your Apple Pencil firmly there while not draining your battery life. I know it’s another investment, but I definitely find it useful because I find I don’t really have to charge my Apple Pencil since the battery lasts for so long and when I do I just leave it charging while my iPad itself is charging.


But as far as something Apple could do, it would be cool to see a software update in the future that allows you to keep your Apple Pencil on the iPad without it draining your battery. Maybe when the pencil is 100% and the iPad recognizes it and doesn’t drain the battery. Or a window asking if you want it to charge the pencil.

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
