Sure. See the attached photo for the charging battery and two dumps:
when charging (and showing the wrong time left) and discharging (and
showing the correct time left).

Title:
  Power indicator shows wrong time left to charge on Lenovo Ideapad Y580

Status in “indicator-power” package in Ubuntu:
  Incomplete

Bug description:
  The power indicator shows time left to charge being 5, 4, 3, 2, 1 or
  "Time left unknown" instead of the real duration.

  The time left on battery power is correctly computed. When I remove
  the power, it takes a little bit until it switches from the wrong
  duration to charge to the real time left on battery power, sometimes
  going to sleep as a result of thinking it has little power left.

  See the screenshot for the displayed value.
