Hi jhc,

Sorry for the late reply, there has ben low staffing due to summer vacation.

[quote userid="79834" url="~/f/nordic-q-a/63834/power-consumption-of-openthread-mtd-node"]But the power consumption is nearly the same as above picture. It seems that the power consumption has not any change, why?[/quote]

Reducing the tx power does not necessarily have a huge impact on the power consumption.

Yes enabling the internal DC/DC should help reduce the power consumption.

Disabling the USB might also help reduce the power consumption but I am not certain of the impact as I have not tested this myself.

Have you tried the online power profiller? https://devzone.nordicsemi.com/nordic/power/w/opp/2/online-power-profiler-for-ble

Here is a link on power optimizing that might be of interest https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/optimizing-power-on-nrf52-designs

Link to a different case on the nrf52840 dongle power consumption, https://devzone.nordicsemi.com/f/nordic-q-a/49572/what-is-lowest-power-consumption-template-code-for-nrf52840-dongle

Again sorry for the late reply

Regards,
Jonathan
