My Apple MacBook Pro frequently shows me a little notifier that says something like “charging has been stopped at 80% since we notice you infrequently use your battery: you may choose to charge to 100% by doing the following…“ Additionally, my iPhone 11 says something like “charging is proceeding at a slow rate since we see that you will not pick up your phone until early tomorrow morning“.
