I just got an Apple Pencil 2. I don't keep it connected all the time. When I'm not using it, I keep it in a little pocket in my case. It will discharge overnight to almost 0%. Is that normal or is it defective? Because of the orientation I like to use my iPad, it's not convenient to keep it attached all the time because it will be at the bottom of the iPad so it's always coming off. Just wondering if I need to have it replaced while under warranty. It does charge super fast, so I just charge it back up when I need it. Thanks for any advice!
