Show battery life and charging state

Print Linux laptop battery status

Usage

battery [-s]

-s: Print in compact mode, can be used with tmux, zsh, etc.

Setup

Please attach the battery to your laptop before compiling battery.

Download the source code and chdir to the directory. Type make to compile the program into a file battery.

Why don't use a script-based solution?

I use this program to display battery status in tmux statusbar. The status refreshes very often, so I hope it can be cheaper to get the battery state. To see the difference, type the folloing command in bash to measure how long it takes to run battery 1000 times:

time for i in `seq 1 1000`; do ./battery > /dev/null; done

Search for other script-based solutions online (battery.py, battery.sh, ...) and do the same thing to them. Compare the result and you will see the savings.
