https://devzone.nordicsemi.com/f/nordic-q-a/14923/nrf52832-nfc-high-consumptionHi, after reading the NFC with an smartphone the power consumption stays very high without doing anything else... I don&#39;t know if this is related to this bug: &quot;NFCT does not release HFCLK when switching from ACTVATED to SENSE mode.&quot; I&#39;m usingen-USTelligent Community 13Mon, 04 Jul 2016 11:20:09 GMThttps://devzone.nordicsemi.com/thread/56956?ContentTypeID=1Mon, 04 Jul 2016 11:20:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5e09de6d-ea10-42ae-813e-046f41d08679Stian R&#248;ed Hafskjold<p>Yes this is related to the bug you referred to. You need to define <code>HAL_NFC_ENGINEERING_BC_FTPAN_WORKAROUND</code> in your project. Now the <code>hal_nfc_field_check()</code> function will be called when the field is lost and reset the NFCT module. If the NFCT is not reset the HFCLK will continue to run and draw current.</p> <p>Please read <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/group__nfc__fixes.html?cp=5_0_0_6_5_1_1">this</a></p><div style="clear:both;"></div>
