Very high power consumption on system off demo

[Bartosz22]

To measure the current consumption during system off on the NRF52833DK, I followed these steps:

1. Cut the SB40 bridge.
2. Connected a multimeter to P22.

Here's what I observed:

• When powered from USB, the board consumes around 5mA in system off mode.
• When powered from a coin battery, the current consumption is about 4mA.

I didn't modify any configurations in the demo program. Did I miss any configuration steps?

Hello,

Could you tell me which SDK version you are using? Have you made any changes to the System Off sample from the SDK? If so, could you provide details on the updates you made? I assume you are working with the NFC: System Off sample. If not, could you specify which sample you are using?

Kind regards,

Abhijith

I'm using zephyr 3.6.99 with 2.7 nrf connect sdk. I didn't make any changes to the NFC system off sample code, just upload it to the nrf52833dk.
