No idea, maybe that’s where you see the battery level? I like to imagine the coffee mugs are just chatting amongst themselves.
“Ugh Peggy with her fucking black coffee again, we make it through 15 minutes of work and we’ll be back in here so we can refill … Same shit every morning”.
“You’re telling me, Clyde’s been milking his coffee break for 45 minutes now, I doubt he even remembers telling Terry we were going to send him that paperwork”

It’s to monitor battery life and adjust temperature, you can usually do both via physical interaction with the warmer, but they offer an app that may display more info or allow more precise control over the temp. Usually the app is completely optional.
