Before I got my new MacBook, one of my worries was having it plugged to power 24/7. I do most of my work on it from home, and it’s plugged into a KVM switch to my external Monitor, Keyboard, and Mouse, along with my Windows PC.

a macOS window showing that the battery charge is “on hold” and the battery is holding an 80% charge. Below, a couple of more options to choose from, including battery settings.

Today, I noticed the above window for the first time (it shows up after you click the battery and charger icon in the top menu), and it was odd to see my battery is only at 80%. Alarmed, I checked Apple’s documentation about this. It turns out not only there’s no issue with leaving the battery connected to power 24/7 (per research I did previously), but macOS expects it from my habits and allows the battery to discharge to a certain level to keep it healthy.
