  24       <div class="date">15th March 2016</div>
  25       <div class="body"><p>Back in September, I blogged about
  26 <a href="http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html">the
  27 system I wrote to collect statistics about my laptop battery</a>, and
  28 how it showed the decay and death of this battery (now replaced).  I
  29 created a simple deb package to handle the collection and graphing,
  30 but did not want to upload it to Debian as there were already
  31 <a href="https://tracker.debian.org/pkg/battery-stats">a battery-stats
  32 package in Debian</a> that should do the same thing, and I did not see
  33 a point of uploading a competing package when battery-stats could be
  34 fixed instead.  I reported a few bugs about its non-function, and
  35 hoped someone would step in and fix it.  But no-one did.</p>
  36
  37 <p>I got tired of waiting a few days ago, and took matters in my own
  38 hands.  The end result is that I am now the new upstream developer of
  39 battery stats (<a href="https://github.com/petterreinholdtsen/battery-stats">available from github</a>) and part of the team maintaining
  40 battery-stats in Debian, and the package in Debian unstable is finally
  41 able to collect battery status using the <tt>/sys/class/power_supply/</tt>
  42 information provided by the Linux kernel.  If you install the
  43 battery-stats package from unstable now, you will be able to get a
  44 graph of the current battery fill level, to get some idea about the
  45 status of the battery.  The source package build and work just fine in
  46 Debian testing and stable (and probably oldstable too, but I have not
  47 tested).  The default graph you get for that system look like this:</p>
  48
  49 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-03-15-battery-stats-graph-example.png" width="70%" align="center"></p>
  50
  51 <p>My plans for the future is to merge my old scripts into the
  52 battery-stats package, as my old scripts collected a lot more details
  53 about the battery.  The scripts are merged into the upstream
  54 battery-stats git repository already, but I am not convinced they work
  55 yet, as I changed a lot of paths along the way.  Will have to test a
  56 bit more before I make a new release.</p>
  57
  58 <p>I will also consider changing the file format slightly, as I
  59 suspect the way I combine several values into one field might make it
  60 impossible to know the type of the value when using it for processing
  61 and graphing.</p>
  62
  63 <p>If you would like I would like to keep an close eye on your laptop
  64 battery, check out the battery-stats package in
  65 <a href="https://tracker.debian.org/pkg/battery-stats">Debian</a> and
  66 on
  67 <a href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
  68 I would love some help to improve the system further.</p>
