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

I want this to be executed every 50 ms ?
You could write a script with above commands, that queries every 50ms.

Set-up ADB on Windows ?
A quick Google search should help you out.

To make proper use of Dumpsys,

  • Thanks Don but unfortunately the blog link says the blog does not exist. Please can you help me. – Protocoder Dec 13 '14 at 15:29
  • Thank you for the wonderful link. I believe we need to install adb to feed the commands. May I ask one question 1. Say I want to continuously report the power, do I have to feed "adb shell 26" ? I see time parameter missing say I want this to be executed every 50 ms. 2. My other question is please tell me the step by step process of feeding same information from windows command prompt. Thanks a lot – Protocoder Dec 13 '14 at 18:52
