The battery (time remaining) information shown by Linux Mint 17 on my Asus Zenbook UX32LA is inconsistent. When I unplug it from the AC power (99% charged), it says 4:55h, after 1 min it shows 7:15h, at 75% it shows 6:25h and then after 1 min it shows 3:30h. The ASUS website states it should be "ok" to work for up to 7-8h.

How can I make the time reported consistent? Some suggestions/solutions ?

ASUS ZenBook UX32LA-R3086H

TB - taskbar battery information; TRB - terminal battery information through acpi -b

Better example: I checked now at 71% and TB is was 5:30h, with TRB shows 5:16h, now at 70% it shows TB shows 6:15h and at TRB shows 5:55:50h

Very awkward!

    I trimmed the irrelevant details about the various issues you've already solved and provided a link to your laptop's model. Please check that I've given the right model (there is no UX32L, only UX32LA and UX32LR). Also, please edit and clarify where this remaining time is reported and whether you get the same answer if you open a terminal and run acpi -b. Finally, you should know that since this kind of information depends on the system communicating with the battery correctly, it is often problematic on Linux since vendors don't always provide Linux-specific software for this. – terdon Nov 23 '14 at 13:14
  • Really sounds like a driver bug. It's getting the max duration from the hardware and obviously it is getting it wrong and inconsistently. If the % seems sane, just pay attention to that and ignore the time. – goldilocks Nov 23 '14 at 14:45
  • But how should I guess +- when is the battery gone ? – Sashka Nov 23 '14 at 15:34
