To further clarify what Kerm was saying, this is what you should run to compile it:
Code:
gcc -lm battery.c -o battery.o

That's correct. Thank you for the point of clarification, Tanner.
Oh sorry I retried it:


Code:
Battery is currently charging.
Battery charge level is 9.658778%.
Remainging 0:8


Linux tells me it's 7.7% and 1hour 20 minutes left.

I only have 1 battery and am indeed charging.

2% is not bad, it's actually very good (or maybe what Linux tells me is wrong) Smile I just don't get the "0:8".
Well iirc he is reading the values from sysfs, so the program may be reading it differently or Kerm's program has a bug.
This program reads directly from the ACPI measurement data. The official Linux tool runs in the background, and can estimate the rate more accurately, since it keeps track of historical data. I find that on my laptop the two tools estimate very close to each other, though.
Well, but about "0:8", what does it mean? 0hours 8 minutes?

That's correct. If you want to build and improve on this, I would welcome it! You could start by changing the minutes display to %02d, which would make the minutes look like "32" or "08".
