3C All-in-One Toolbox on Samsung Galaxy S21

Today you'll find results of benchmark tests on Samsung Galaxy S21.


The test environment:

  • Samsung Galaxy S21, rooted (can use 3C Companion on non rooted devices).
  • 3C All-in-One Toolbox version 2.9.1d.
  • Recording apps CPU usage at an interval of 20 minutes.
  • Recording battery in "real-time", as soon as OS changes %, mV or temperature.
  • Recording CPU/GPU temperature and load and screen state only.


Results shows that the toolbox consumes about 30 seconds of CPU per day, or 0.035% of CPU. Not too bad, but could be better. That device had a lot of apps running in background even when in standby, causing it to run a low 2 days in standby!

Note that the list of apps shown below only shows some of the lowest consumer. Some apps at the top of the list where using more than 1 minute of CPU during a 6 hours period in standby!


It will definitely run better with task killer!
