Wrong battery status for Track pad
The battery status display (in the system prefs or in the Bluetooth status pulldown in the menu bar) of my wireless track pad is mostly wrong:
often it sticks at 15 %, and sometimes it shows 50 % as a maximum — no matter how long it was charged.
Did you experience the same or know a fix?
