View running processes and CPU usage in Android 7 (Nougat)?

Question

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. — V T Vishwanath, Apr 11 '17 at 15:30
Thanks, but is it possible to also get it to display the CPU usage too? — laurent, Apr 11 '17 at 15:37
Have you tried other alternatives like system monitor, I think they pretty much do the same job — xavier_fakerat, Apr 11 '17 at 15:47
@xavier, yes I've tried a few of them, but couldn't find one that was working. — laurent, Apr 11 '17 at 15:51
Thats okay its only I am not using android 7 now, could have tested a few, but will check in my emulator for compatibility — xavier_fakerat, Apr 11 '17 at 15:52
@this.lau_ Apps like "Kernel Adiutor (ROOT)", "Cpu Monitor" will give the Total CPU usage with each core usage (with graph). But they will not show individual process (app) CPU usage. — V T Vishwanath, Apr 12 '17 at 17:12

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:

Install and launch Termux (Google Play)
Open Termux and run apt install top
Run top

This definitely doesn't work on 4.4 or lower. Because Termux doesn't support 4.4 and below. – iBug May 01 '17 at 23:51

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. – laurent May 02 '17 at 08:31
You can use"su" command before "top". – user219263 May 03 '17 at 23:09

This requires root? – roxan Jun 05 '17 at 04:39

same problem, only shows two processes with 0% cpu usage, while my phone is seriously overheated. su command doesn't work as well :-( – Tomas Jul 06 '18 at 11:42
answers is correct, but in my case i just use "pkg install htop" and then htop – Alexandr.Salin Jun 17 '19 at 17:18
Apps on Android can see only its own files and processes, that's why you see only processes started by Termux. Using root is probably the only way to see other processes, unfortunately. – David Ferenczy Rogožan Mar 17 '20 at 01:59
