You just sat down to sketch or take notes, and your stylus is dead. Again. Honestly, it’s frustrating when you expect that sleek white stick to be ready, but instead, you’re staring at a "0%" notification—or worse, no notification at all. Apple Pencil 2 charging is supposed to be "invisible" and effortless, yet here we are, troubleshooting magnets and Bluetooth menus.
Basically, the second-generation Apple Pencil ditched the awkward "lolipop" charging method of its predecessor. No more plugging it into the bottom of your iPad like a weird antenna. Now, it’s all about induction.
But "simple" doesn't always mean "flawless." I’ve seen enough iPads and Pencils to know that when things go sideways, it’s usually because of a few specific, often overlooked reasons. Let's dig into what’s actually happening under the hood.
How Apple Pencil 2 Charging Actually Works
The magic happens on the right side of your iPad. You’ll see a small, dark magnetic strip. When you snap the Pencil there, the iPad uses inductive charging to transfer juice. It's the same tech as MagSafe or Qi charging, just miniaturized.

Most users don't realize that the connection isn't just for power. It’s a data handshake. The moment it clicks, Bluetooth says "hello" and the charging animation pops up. If that animation doesn't appear within two seconds, something is blocking the conversation.
How fast is it?
Very.
Apple doesn't give a formal "0 to 100" time, but real-world testing shows you can get about 30 minutes of use from just 15 seconds of charging. A full top-off usually takes under 30 minutes. Because it lives on the side of the iPad, it’s designed to stay at 100% almost constantly.
The Compatibility Trap
Here is where it gets annoying. You might have a brand new iPad and a 2nd Gen Pencil, and they simply won't talk. Why? Because Apple changed the magnets.
With the release of the M4 iPad Pro and M2 iPad Air (and subsequent 2025/2026 models), the front-facing camera moved to the landscape edge. This move forced Apple to relocate the charging coils. Consequently, the Apple Pencil 2 charging system is physically incompatible with the newest M4/M5 iPad Pro and M2/M3 iPad Air models. For those, you need the Apple Pencil Pro.

If you try to snap an older 2nd Gen Pencil onto a new M5 iPad, it might stick (sort of), but it won't charge. It’s a hardware mismatch that software can’t fix.
Devices that actually support Apple Pencil 2 charging:
- iPad Pro 11-inch (1st through 4th Gen)
- iPad Pro 12.9-inch (3rd through 6th Gen)
- iPad Air (4th and 5th Gen)
- iPad mini (6th Gen)
If you're using an iPad mini A17 Pro or any "M-series" iPad from 2024 onwards, your 2nd Gen Pencil is essentially a very expensive paperweight.
Why Your Pencil Isn't Charging (The Real Reasons)
If your gear is compatible but still dead, don't panic. It's usually one of these three culprits.
1. The "Skinny" Case Problem
I love a good protective case, but many of them are too thick. Even if the case has a "cutout" for the Pencil, a millimeter of plastic can be enough to break the inductive link. If your Apple Pencil 2 charging is intermittent, take the case off. If it starts charging immediately, your case is the villain. Look for "Pencil-compatible" cases that have an extremely thin membrane or a complete gap over the charging strip.
2. The Bluetooth Glitch
Since charging relies on a Bluetooth handshake, a software "hiccup" can stop the flow of power. It sounds silly, but toggling Bluetooth off and on fixes about 40% of charging issues. If that fails, go to Settings > Bluetooth, tap the "i" next to your Pencil, and select Forget This Device. Snap it back on the side to re-pair. This "fresh start" often jumpstarts the charging cycle.
3. The Deep Sleep Death
Lithium-ion batteries hate being at 0%. If you leave your Pencil in a drawer for six months, the battery can fall into a "deep discharge" state. At this point, the iPad might not even recognize it's there.
Try this: attach it to the iPad and leave it for a full hour. Don't touch it. Sometimes the battery needs a slow "trickle" to wake back up before the fast charging kicks in.
Battery Drain: Is the Pencil Stealing Power?
Technically, yes.
The Apple Pencil 2 is always "on." It has an accelerometer inside that wakes it up the moment it senses movement. If you're carrying your iPad in a backpack, the Pencil is constantly waking up, checking for a connection, and sipping power from the iPad to stay at 100%.
Some users report their iPad battery dropping 5–10% overnight because the Pencil is docked. If this bothers you, you can turn off Bluetooth when you aren't using it. Or, just accept it as the cost of having a stylus that's always ready to go. Honestly, the convenience usually outweighs the minor drain.
Pro Tips for Longevity
Don't let the battery sit at 0% for weeks. That's the fastest way to kill the internal cells, which, by the way, are not replaceable. If the battery dies, you're buying a new Pencil.
Clean the contacts occasionally. Skin oils and dust can build up on the flat side of the Pencil or the iPad's magnetic strip. A quick wipe with a dry microfiber cloth ensures the magnetic connection is tight and the inductive transfer is efficient.
If you've tried the "Forget Device" trick, removed your case, and checked your compatibility, but it’s still not charging, it’s time to visit the Genius Bar. These things are precision instruments, and sometimes the internal charging coil just gives up.
Actionable Next Steps:
- Check your iPad Model: Go to Settings > General > About to ensure you aren't trying to use a 2nd Gen Pencil with a newer M-series iPad that requires the Pencil Pro.
- Strip the Case: Remove any iPad cover and attach the Pencil directly to the metal edge to rule out physical interference.
- Perform a Hard Reset: If it's still stuck, press and quickly release Volume Up, then Volume Down, then hold the Power button until the Apple logo appears. This often clears system-level Bluetooth hangs.
