RE: Debugging Matter Over Thread power consumption

Hi Robert,

Good to hear that the issue was resolved.

Please refer to the following documentations:

1) Matter over Thread: Power consumption and battery life

This goes through factors which affect power consumption, setup for measurements and performed measurements and results.

2) Reducing power consumption in Matter

This goes through the use of low power configurations and which peripherals and modules to disable if they aren't in use. There is also information here about enabling device power management, using sleep modes, disabling serial logging and LEDs as well as the use of RAM power-down in order to decrease power consumption. You can also read in this about operating modes and switching to idle mode (using the given Kconfig options) to save power.

Best Regards,

Samruddhi

I went back and disabled a few more options having to do with logging and was able get rid of the 10ms wake up. I am not sure exactly which one it was, since I'd tried disabling some of them previously. I guess my suggestion would be to start with prj_release.conf when measuring power initially. Then add options you might like to add and check to see what happens to power consumption after adding each one.

However, if anyone has suggestions for how to debug Matter code, I'd be interested in how.
