To improve quality of mobile applications on Android platform in sense of energy-efficiency, the programmers need appropriate tools. One of the method to estimate energy consumption of mobile applications is Energy Profiling (for example, using reference implementation - Android Power Profiles). This method allows to estimate energy consumption online, i.e. without using any external devices, while using reference data obtained via prior using of offline measurements tools.

The first-class entity of this method is Energy Profile of target device that contains information about distinct energy consumption of each component. There are at least two reasons why it is may be needed to derive Energy Profiles for specific Android device. First is inappropriate quality of built-in Android Power Profile for most of the devices presented on market. The significant improvement may be achieved even using reference power model developed for Android Power Profiles while using updated (i.e. derived for concrete target device) Power Profile. The second reason is using non-reference power models. Of course many engineers may consider using of specific power models that are suitable for Energy Profiling of very specific applications. In this case, the will need to have a method to obtain Energy Profile for this private power model.
