The work cannot go on any longer.
On Android phones, the energy consumption values for each part of the phone (CPU, LED, GPS, 3g, and so on) are Power_profile.xml
File, and the system is set up--in battery usage, the usage of the statistics is also based on the value of Power_profile.xml as the base parameter
the. How does Android phone get power_profile.xml files? Next we'll cover the problem in more detail:
