My previous Intel-based iMac used a keyboard and mouse that used batteries. My new 24" M1 iMac of course has the wireless Magic Mouse and Magic Keyboard. I'm just wondering if it's best to let these devices completely go dead before charging? What do most people do? Share them at 50% or let then get very low / dead before charging? (by the way - I notice the charging port for the mouse is on the bottom of the device so that you can't use it while charging. Is it just me or is that a really poor design?)
