Apple pencil lagging while using for prolonged time

Begin with a forced-restart of your iPad - as this will often clear an isolated software issue.

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

If you continue to experience difficulties, you might be best advised to seek assistance directly from from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page.

Alternatively and perhaps easier, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

The free iOS Notes is NOT really an ideal notes app to be using.

The free Notes app is NOT that great a notes app to be using on a regular basis.

The default iOS Notes app is free and is of very limited features/functionalities.

If you really want to get the most out of that Apple Pencil and need extra note-taking features, I recommend looking at other third party note taking apps.

Apple's free, default, iOS Notes app is a basic notes apps that Apple includes, more or less, as a example “showcase” app of what could be done when designing/coding a more fully featured note-taking app.

Apple's free Notes app is NOT a full featured notes app and has many useful features NOT available to it.

To make the free iOS Notes app a relatively basic, simple notes app that anyone can, more or less, learn fairly easily, Apple's Notes app has eschewed many useful features found in other more powerful and robust/feature-rich, third party note taking apps.

Apple has always treated their iOS Notes app in a way where the app is like only approx. 80% “there”.

Apple's iOS Notes app is notorious for major issues, like deleting notes at random, arbitrary times and deleting entire groups of notes unexpectedly, for no real reason

My wife and I had these issues happen, on a handful of occasions, long ago, to the point that that Apple's free iOS Notes app is no longer a trusted, reliable app to use for ANY extensive note-taking.

Also, to also emphasize how basic the free iOS Notes app is, Apple ONLY upgrades/updates this app once a year with a new iOS/iPadOS version introduction every September/October.

Forget continuing to use Apple's free iOS Notes app.

If you want “piece of mind” and know that notes can't just “accidentally and mysteriously” disappear, at random, look to other third party free OR paid notes apps from the Apple iOS App Store.

There are third party notes apps that have been with iOS/iPadOS and Apple devices for, at least, 5 years, or more and have a much better track record of reliability and can automatically save notes to other data storage/backup services other than just Apple iCloud, like Google Drive, DropBox, Amazon Cloud services, and/or BOX or other similar data storage/backup services.

If you need more features from a notes/note taking app, I recommend you look to the Apple iOS App Store for more fully featured, AND much more stable, third party Notes apps that get many more regular updates throughout the years!

Here is an incomplete list of notes/note taking apps you may wish/want to look at that are more robust and feature-rich, in no particular order.
