https://devzone.nordicsemi.com/f/nordic-q-a/82261/troubleshooting-high-sleep-currentHi everyone, I have an nRF52832 embedded as part of a dual chip (connected via SPI) and I&#39;m looking to reduce the sleep current as much as possible. I&#39;m currently measuring a 2mA sleep current, which is a lot higher than I&#39;m expecting (~1.7uA for systemen-USTelligent Community 13Wed, 01 Dec 2021 13:34:12 GMThttps://devzone.nordicsemi.com/thread/341529?ContentTypeID=1Wed, 01 Dec 2021 13:34:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8590f008-5170-406e-821a-ad8e742b2dd6J&#248;rgen Holmefjord<p>Hi,</p> <p>Do you have any peripherals enabled in your code, apart from SPI? The typical sources of this current consumption is EasyDMA + HFCLK, which is typically caused by UART enabled in RX mode, or SAADC enabled.</p> <p>If you can post your code, it would be easier to see what could cause the increased current consumption.</p> <p>There is also many cases and guides here on DevZone regarding optimization of current consumption.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
