  24       <div class="date">23rd May 2016</div>
  25       <div class="body"><p>Yesterday I updated the
  26 <a href="https://tracker.debian.org/pkg/battery-stats">battery-stats
  27 package in Debian</a> with a few patches sent to me by skilled and
  28 enterprising users.  There were some nice user and visible changes.
  29 First of all, both desktop menu entries now work.  A design flaw in
  30 one of the script made the history graph fail to show up (its PNG was
  31 dumped in ~/.xsession-errors) if no controlling TTY was available.
  32 The script worked when called from the command line, but not when
  33 called from the desktop menu.  I changed this to look for a DISPLAY
  34 variable or a TTY before deciding where to draw the graph, and now the
  35 graph window pop up as expected.</p>
  36
  37 <p>The next new feature is a discharge rate estimator in one of the
  38 graphs (the one showing the last few hours).  New is also the user of
  39 colours showing charging in blue and discharge in red.  The percentages
  40 of this graph is relative to last full charge, not battery design
  41 capacity.</p>
  42
  43 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-rate.png"/></p>
  44
  45 <p>The other graph show the entire history of the collected battery
  46 statistics, comparing it to the design capacity of the battery to
  47 visualise how the battery life time get shorter over time.  The red
  48 line in this graph is what the previous graph considers 100 percent:
  49
  50 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-history.png"/></p>
  51
  52 <p>In this graph you can see that I only charge the battery to 80
  53 percent of last full capacity, and how the capacity of the battery is
  54 shrinking. :(</p>
  55
  56 <p>The last new feature is in the collector, which now will handle
  57 more hardware models.  On some hardware, Linux power supply
  58 information is stored in /sys/class/power_supply/ACAD/, while the
  59 collector previously only looked in /sys/class/power_supply/AC/.  Now
  60 both are checked to figure if there is power connected to the
  61 machine.</p>
  62
  63 <p>If you are interested in how your laptop battery is doing, please
  64 check out the
  65 <a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>
  66 in Debian unstable, or rebuild it on Jessie to get it working on
  67 Debian stable. :) The upstream source is available from <a
  68 href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
  69 Patches are very welcome.</p>
