How to get higher precision of “CPU%” than that from TOP command?

Question

When I use TOP command, I could get the following info:

shell@android:/ $ top -n 1                                                     

User 31%, System 10%, IO         


        

Answer 1

Try this:

ps -eo pcpu,pid,user,args | sort -r -k1 | less 

%CPU   PID USER     COMMAND
 9.0  2721 user   bash
 1.4   956 root     ...
 0.5  2212 user   ...

EDIT:

You can use adb shell and busybox (http://www.busybox.net/downloads/BusyBox.html)

adb shell busybox top

c:\ adb push busybox /system/bin
c:\ adb shell
# busybox top 

CPU:  2.3% usr  3.1% sys  3.9% nic 90.5% idle  0.0% io  0.0% irq  0.0% sirq
