Thanks for the update. However, please note that the chip is powered down in System OFF mode. If you need the chip to continue to operate and wake-up on application interrupts, you need to use System ON mode.

Hello
Thank you man, the problem is solved.
NRF9160DK & System OFF
this thread was the answer to my question. which was referred in your provided lead.
I guess there is also some issue in my custom board, it is not getting better than 600 uA. But luckily I had an old board with just nrf9160 on it and I got to 2.3uA on it.

Hello,

An empty while loop will prevent the CPU from entering idle. Have you tried adding k_msleep() to this loop instead (e.g. k_msleep(1000))? This will allow the program to enter the idle thread where the chip will enter System ON (sleep) mode. Please also make sure that CONFIG_SERIAL is set to '=n' in your project configuration so that the UART driver is disabled.

- Power optimization

PM device is only needed if you need to power down peripherals at runtime.

Best regards,

Vidar

Apply the search above, select sort "Most Recent".

You get a short list, the 4th item is

I have searched alot about it and could not find any particular lead, thats why I posted here. Every other thread is about some particular module like LTE consumption or something else and are almost 2 years old.

Use "nrf9160 AND power AND consumption" to search the forum.
