Just as important is how much power all of the smartphone guts need to run, but it&#8217;s a challenge to see that information in detail. Or at least it was a challenge.<\/p>\n<p>This morning <a href=\"http:\/\/spectrum.ieee.org\/computing\/embedded-systems\/making-smartphones-powersmarter\">I was reading up on the IEEE&#8217;s website<\/a> and found a free Android application for this very situation. It&#8217;s called <a href=\"http:\/\/powertutor.org\/\">PowerTutor<\/a> and comes by way of the University of Michigan. I installed the software on my Nexus One and while not exactly the most intuitive application to use, it does provide insight as to what&#8217;s using the most juice &#8212; radios, the display and even how much power is consumed by particular applications.<\/p>\n<p>After just a few minutes of use, I&#8217;m finding that PowerTutor easily surpasses the native power consumption offering that&#8217;s native to Android. To see what Google currently includes, just tap Settings, About Phone, Battery Use in a recent version of Android. The native feature simply shows the percentage of battery use by component or application.<\/p>\n<p>PowerTutor gets down to the nitty-gritty and can graph the actual power consumption over time at the component, software or radio level. And all things being equal, I&#8217;d rather use a <em>less<\/em> power intensive application over a similar one that eats up my handset battery at a faster rate. The differences in power usage might be small at a given point in time, but <em>over<\/em> time, they can add up.<\/p>\n<p>Although consumers might find occasional use for PowerTutor, it&#8217;s likely to present a bigger benefit to developers. With a tool like this, they can monitor the power requirements needed for their software &#8212; and potentially optimize the code to reduce those requirements. If they can make the software run on less juice, it could be a compelling feature to tout.<\/p>\n<p>PowerTutor was created for and &#8220;works best&#8221; on a G1 handset, but the U of M creators estimate that it&#8217;s still reliable on other Android devices. The application itself uses about 5% of a handset&#8217;s CPU, so running it all the time is likely to be counter-productive. Why run down the battery with software that measures the run down of the battery, right?<\/p>\n<p><em>Image Credit: PowerTutor.org<\/em><\/p>\n<p><strong>Related research on GigaOM Pro (sub req\u2019d):<\/strong><\/p>\n<p><a href=\"http:\/\/pro.gigaom.com\/2009\/12\/green-it-winners-and-losers-of-2009\/\">Green IT Winners of Losers in 2009<\/a><\/p>\n<p>  <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/gocomments\/jkontherun.wordpress.com\/57833\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/comments\/jkontherun.wordpress.com\/57833\/\" \/><\/a> <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/godelicious\/jkontherun.wordpress.com\/57833\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/delicious\/jkontherun.wordpress.com\/57833\/\" \/><\/a> <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/gostumble\/jkontherun.wordpress.com\/57833\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/stumble\/jkontherun.wordpress.com\/57833\/\" \/><\/a> <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/godigg\/jkontherun.wordpress.com\/57833\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/digg\/jkontherun.wordpress.com\/57833\/\" \/><\/a> <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/goreddit\/jkontherun.wordpress.com\/57833\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/reddit\/jkontherun.wordpress.com\/57833\/\" \/><\/a> <img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/stats.wordpress.com\/b.gif?host=jkontherun.com&#038;blog=4479943&#038;post=57833&#038;subd=jkontherun&#038;ref=&#038;feed=1\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We smartphone addicts are\u00a0constantly\u00a0bandying around battery specifications in millamps and Volts, but the power pack itself is only part of the run-time equation.
