Android Power Profiling

We already discussed power consumption and battery life in mobile devices, but two years has passed and it's time to revisit the issues and talk about practical approaches to building battery-frugal apps. Thankfully, Frank Maker is back to share his wisdom and lessons learned from his PhD-research on the subject of battery use in mobile.

Smartphone applications are power hungry and continually outpace slow mobile battery storage improvements. In order to avoid bad user experience from wasting battery life, developers can profile the power consumption of their applications during design. In this talk we will discuss power estimation using software models, external power measurement using benchtop equipment, and measurement using built-in battery measurement units (BMUs).  The pros and cons of each technique will be presented along with some tricks of the trade to make testing easier.

As usual, food, drinks, and venue will be provided by our sponsors.

About Frank Maker

Frank Maker is a Ph.D. candidate at the University of California, Davis studying Embedded Software and Systems.  His academic work focuses on real-time smartphone power profiling to adapt software to changing energy conditions.  Previously he interned for both Google and Broadcom's Android systems team and delivers corporate Android Internals training for Marakana. Before smartphones his career started in automotive embedded software with Motorola Automotive and BMW. In 2005 he received his B.S in Computer Engineering and B.A. in German from the University of Rhode Island and his M.S. in Electrical and Computer Engineering from the University of California, Davis in 2010.

    Hi Guys. The recording from this meetup is now online!

    While this event was certainly more on the *hardware* side, it made me realize how much more we need to worry about our energy use on the *software* side.

    On that note, I recommend you guys check out a white-paper titled "Who Killed My Battery: Analyzing Mobile Browser Energy Consumption" ( One interesting conclusion they came up with "by modifying scripts on the Wikipedia mobile site we reduced by 30% the energy needed to download and render Wikipedia pages with no change to the user experience". Awesome!

    Oh, and I also uploaded my photos from the last night's event:

    I had expected application profiling rather than the electrical power consumption profiling, but it was still a very good presentation.

      +1. I was expecting more depth on the "software modeling" part, but there was very little of it. Nevertheless, this does not take away the fact that the presentation was good overall - just more hardware centric.

    Hi Guys,

    I have a question. Only the developers are attending this meetup or are there other people who are looking for android/mobile developers attending as well?

    Anyone looking for a android/mobile developer?
