Fetching device data through ADB on Windows

问题:

If I have Android phone connected via USB, how do I know the commands I can send via USB to get Information like

1. core temperature of the device,
2. version of android,
3. power consumption details, etc.

Can I then use ADB logs, command to interact with Android mobile. Please may i know the process apart from commands if I have to send commands via ADB.

To get information from an android device, you can always use the following tools.

Use utilities like dumpsys or getprop.
Query from /sys/ or /proc/.

Eventually all utilities, fetch information from /proc or /sys, so you can directly investigate into these.

You could use dumpsys tools to get information:

1. Core temperature of the device I'm not sure, what exactly do you mean by core temperature of the device.

   1. Temperature of Device: ^Note

      $ adb shell cat /sys/class/thermal/thermal_zone0/temp
      37
      

   2. Temperature of Battery:

       $ adb shell cat /sys/class/power_supply/battery/device/power_supply/battery/temp
       285  
      

      or

      $ adb shell dumpsys battery                                
      Current Battery Service state:
      AC powered: false
      USB powered: true
      Wireless powered: false
      status: 2
      health: 2
      present: true
      level: 15
      scale: 100
      voltage: 3768
      current now: -357254
      temperature: 285    # <---- Temparature.
      technology: Li-ion
      

2. Version of android

   $ getprop ro.build.version.release  
   4.4.4   #<--- Android Kitkat 4.4.4
   

3. I'm not completely sure how you can get exact information: You could start with,

   $ adb shell dumpsys power 
   POWER MANAGER (dumpsys power)
   
   Power Manager State:
           ....
   

Note: Results on a Linux System.

$ acpi -t      # <--- apci power utility/tool.
Thermal 0: ok, 29.8 degrees C
Thermal 1: ok, 27.8 degrees C

$ cat /sys/class/thermal/thermal_zone0/temp 
27800

You could write a script with above commands, that queries every 50ms.
