https://devzone.nordicsemi.com/f/nordic-q-a/78387/nrf52833---saadc-driver-power-consumptionHi Nordic team, I noticed that SAADC driver is consuming most of the power in Sleep state. In my application, the processor is in SYSTEM OFF state for 80% of the time (runs only for 4h over a 24h period). However, it&#39;s draining all the battery duringen-USTelligent Community 13Tue, 10 Aug 2021 11:59:09 GMThttps://devzone.nordicsemi.com/thread/324227?ContentTypeID=1Tue, 10 Aug 2021 11:59:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5cb0bba7-8e48-4735-ac0e-350aada7f99fSimonr<p>Hi</p> <p>What battery is this you&#39;re using, and what does the application do once awake? Have you measured that it is the SAADC peripheral drawing most of the current?</p> <p>Also, how exactly do you go into System OFF mode in your application? It is recommended to do something like the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/examples_ble.html">sleep_mode_enter() function does in our ble examples</a>, where the device is prepared for sleep to make sure that no peripherals are left running. If you&#39;re not using a SoftDevice in your application, it might be better to check out the<a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/pwr_mgmt_example.html"> pwr_mgmt example</a> that shows off the most common ways of putting an nRF52 in various sleep modes.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
