https://devzone.nordicsemi.com/f/nordic-q-a/124000/nrf54l15-wdt-power-consumption-in-system-on-idleHi, In have the nRF54L15 in System ON IDLE. I can see that enabling WDT31, set up so that it is paused in sleep mode (CONFIG register = 0x4) causes a current increase of ~1uA. This seems like a large current increase for a single peripheral (which isen-USTelligent Community 13Mon, 01 Sep 2025 08:00:58 GMThttps://devzone.nordicsemi.com/thread/547268?ContentTypeID=1Mon, 01 Sep 2025 08:00:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1914d48a-fa8d-4ca6-8f7b-7c7db1e43d3bKenneth<p>Hi,</p> <p>I am not entirely sure about the ~1uA, but in terms of current consumption I can find:<br /><a href="https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/current_consumption/doc/current_consumption.html#ariaid-title13">https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/current_consumption/doc/current_consumption.html#ariaid-title13</a>&nbsp;<br /><a href="https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/wdt.html#ariaid-title23">https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/wdt.html#ariaid-title23</a>&nbsp;</p> <p>So it looks like the WDT will add about 2-3uA (first link), and that the added current is independent of whether it&#39;s running or paused (second link).</p> <p>Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/547114?ContentTypeID=1Thu, 28 Aug 2025 20:47:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1ebf348a-604b-46e1-9472-1e15520a8cb2Kenneth<p>Hello,</p> <p>Let me look into it and get back to you.</p> <p>Kenneth</p><div style="clear:both;"></div>
