Increased power consumption after start up

Increased power consumption after start uphttps://devzone.nordicsemi.com/f/nordic-q-a/120364/increased-power-consumption-after-start-upHi, I am trying to optimize my nrf52840 application for power consumption. If I run simple loop using nrf5 SDK i get ~1.2mA. However with similiar code on Zephyr: I get ~1.7mA. I understand that Zephyr kernel configures some peripherals even beforeen-USTelligent Community 13Wed, 02 Apr 2025 11:48:08 GMTRE: Increased power consumption after start uphttps://devzone.nordicsemi.com/thread/530221?ContentTypeID=1Wed, 02 Apr 2025 11:48:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a0ae585b-983b-45f8-8012-b17ac19f9d84Priyanka<p>Hi Michal,</p> <p>I guess the 1.7mA in Zephyr is mostly because of the background activity from the RTT console, I2C, ADC, Bluetooth, and RTC peripherals. YOu have all these enabled in your prj.conf. So I would suggest you to disable the ones that are unused and you should be able to see a difference.</p> <p>Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
