Check the Battery
The battery in your Apple Pencil has to be charged for the pencil to work. To check the battery status on your iPad and verify whether your Pencil is charged, do the following:
Confirm Pencil Compatibility With iPad
Apple Pencil 1st and 2nd generations run with different models of iPads, so if you’re trying to use your new 2nd generation Apple Pencil with an iPad you previously used with a 1st generation Apple Pencil, it’s not going to work.
Charge the Apple Pencil (2nd generation) by attaching it magnetically to the side of your iPad. Bluetooth must be turned on for the Apple Pencil 2 to charge.Charge the Apple Pencil (1st generation) by plugging it into the lightning connector on your iPad or by using the USB power adapter that came with the Apple Pencil.
The Apple Pencil charges quickly, so if the battery was dead, charging it should get you up and running quickly.

Confirm Bluetooth Is Turned On
The Apple Pencil requires a Bluetooth connection with your iPad to work. If your Apple Pencil doesn’t show up in the list of devices under the Battery widget, or there isn’t a Battery widget at all, it’s most likely that Bluetooth is turned off or needs to be reset. To check, do the following:
Bluetooth and Pencil Not Paired
If your Apple Pencil’s not pairing with your iPad or the iPad has lost the pairing, re-doing the Bluetooth pairing process could resolve your Apple Pencil problem.
Pencil Tip Is Worn
If your Apple Pencil behaves erratically or not at all, the Pencil tip could be worn out. Replacing the tip is simple.
App Doesn’t Support Apple Pencil
Not all apps support the Pencil. To verify your Apple Pencil is working, open a known supported app, such as Notes. The Notes app is a reliable and excellent choice to test your Pencil, and it should be on your home screen. If you don’t have it, download it.
To replace, unscrew the pencil tip in a counterclockwise direction until it comes off, and then install the new tip by screwing the tip clockwise until it feels secure in your Apple Pencil.
Time to Contact Apple
If you’ve tried all these troubleshooting steps and you are still having problems, it is time to contact Apple. The Apple Pencil comes with a one-year limited warranty. If your pencil is no longer covered by the warranty, the cost for battery service is $29, according to Apple. You can either make an Apple Genius Bar appointment or call 1-800-MY-APPLE. You can also visit the Apple support website for a mail-in repair or replacement.
