For most Android users, the battery consumption statistics accessed from the settings may be enough to know exactly what’s going on with the battery. However, for those who are looking for some more advanced and detailed data, the Battery Test Utility app may be of some helpful and practical use.
Developed by XDA Forum Member jacksparao, Battery Test Utility allows users to run different tests on an Android device to calculate an array of information regarding your battery and how it responds to video and music playback, as well as Internet browsing. Presented with a clinical, Holo user interface, users can select an audio, video, or browser test with adjustable settings such as screen brightness, music or video file, and URLs to be visited. When the battery level drops to 15%, the test phase is considered complete, upon which data such as music bitrate, start and end time of the test phase, battery consumption rate, and other settings like the light sensor and accelerometer computed and displayed. The app however, does come in at a rather large size of 118MB, thanks to the HD videos packaged along with it for testing purposes. But do not worry, as the app thankfully does install itself straight onto the SD card.
Battery Test Utility is a great dedicated battery tester, which presents complicated data in an uncomplicated way, unlike many other apps of similar function in the market. It’s a useful app not only for end-game Android users, but also for those curious about just how much of the precious battery is drained by the favorite album, a typical movie, or a bit of web browsing. Jacksparao has made the app available to all who have devices running Android 2.2 and up, and free from the Play store. So if this has gotten you curious, be sure to check out the original thread for more details._________
