The command adb shell dumpsys battery stats will show stats per package to help you determine package usage per application. The results may contain up to 2 weeks of information starting with the most recent.  In this example we see the UID for Google Maps. This UID will be consistent throughout this file as discussed in section 1 of this course. More information on battery usage and battery stats will be provided toward the end of this section. A good reference is https://github.com/google/battery-historian.
