In previous versions of Android, when my phone battery was going down quickly I could open an app like OS Monitor, see what process is using a lot CPU (often it was Evernote or Maps.me), and then kill that process.

However, OS Monitor and similar apps aren't working with Android 7 anymore, I guess due to some change in the system.

So I'm wondering, is there a way that would allow me to see what's consuming CPU in the latest version of Android?

  • In developer options, you can see the "Running Services" which will show all services with their RAM usage.

    Thanks, but is it possible to also get it to display the CPU usage too?

  • Have you tried other alternatives like system monitor, I think they pretty much do the same job

  • @xavier, yes I've tried a few of them, but couldn't find one that was working.

You can use adb shell /system/bin/dumpsys cpuinfo.
This should also work with Oreo.

(Edited - confirmed also not working on 7.1.1 unrooted.)

This should work on any Android version, but you might find the output a bit unfriendly:

  1. Install and launch Termux (Google Play)
  2. Open Termux and run apt install top
  3. Run top

  • This definitely doesn't work on 4.4 or lower. Because Termux doesn't support 4.4 and below.

    Thanks, but it doesn't work either, it only shows two processes (bash and top). I guess low level access to processes is now disabled in new Android version so no app can view them.

  • You can use"su" command before "top".

    This requires root?

    same problem, only shows two processes with 0% cpu usage, while my phone is seriously overheated. su command doesn't work as well :-(
