Battery percentage flipping between real and 93%

🚧 THIS IS A TICKET MIGRATED FROM UPVOTY. The original ticket and comments will be available for a limited time over at:

———————————————————————————
during a trip the other day, the battery percentage kept flipping every 20-30 seconds between the real value and 93%, resulting in some weird graphical status like this one (when the arrival percentage was still to be updated).
