Feature Request: Display battery percentage on screen during powering off

Hi. I'd like to suggest improvement of software to implement display of remaining battery percentage during power off display. I found this function on a Wahoo device and it was extremely useful, as after the ride you had clear information if you needed to plug your computer to the charger. For me It's pretty common that I have to turn the edge on just to check if the battery level is sufficient for oncoming ride/workout.
