Kraken.me mobile: The energy footprint of mobile tracking

Power consumption can make or break the success of mobile applications. This is especially true for applications requiring constant access to sensor readings as sensors tend to consume considerable amounts of energy. A lot of attention has been focused on reducing power consumption for hardware sensors both from a hardware and software perspective. However, mobile phones enable applications to also gather software artifacts employing so called soft sensors, e.g., calendar, contacts, browsing history, etc.
