It is a Forum Nokia application that allows users to monitor battery usage. While it is intended for developers to measure how much battery power their apps consume, everybody can use it to take a look "under the hood" of the phone. It offers a nice graph view of battery usage and a large number of settings that can be modified. To make benchmarking even easier, it has built-in screenshot capability. It also offers various charts and tables for comparison between different recorded moments.
