Learn about energy consumption and battery life on Android devices
San Francisco Android User Group hosted an event on March 30th, 2010 with Frank Maker, Eric Jung, and Yichuan Wang, a trio of very smart PhD students, who shared what they've learned about power consumption / battery life on mobile/Android devices in their years of research.
Specifically, they talked about:
Mobile Architecture - differences with desktop/laptop computers, where power goes, etc.
Measuring Power/Energy - difference between energy and power, battery technology, why the problem isn't going away anytime soon
Software Optimizations - different ideas you can use to lower the power consumption of your application
