/* This plugin is designed to measure your battery performance in real-time.
It will create a big file, read it every ~90 seconds and log the
battery level in /battery.log
When battery level goes below 5% the plugin exits, to avoid writing to
disk in very low battery situations.
Note that this test will run for 10-15 hours or more and is very boring
to watch.
