https://devzone.nordicsemi.com/f/nordic-q-a/28506/why-my-nrf51822-board-current-in-sd_app_evt_wait-is-up-to-9uaIn sd_power_system_off()，the nrf51822-board current is 2uA；And I think the current in sd_app_evt_wait() will be ~4uA(Is it correct)? In sd_app_evt_wait(), the code is same as to in sd_power_system_off(). And I sure I close uart and there is noen-USTelligent Community 13Fri, 29 Dec 2017 12:21:59 GMThttps://devzone.nordicsemi.com/thread/112813?ContentTypeID=1Fri, 29 Dec 2017 12:21:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:93415cf0-f8bc-4418-97ef-2ea6ef54fa09yuyixuantai<p>I have solve this problem with orther device.

Is it possible for you to try a different one? If you saw a difference between two devices it could e.g. be due to poor soldering and small short circuits.</li> <li>Can you try the unmodified ble_app_hrs example in our SDK? If you see a lower current consumption then, we know it is most likely something going on in your code and not a HW issue.</li> <li>Do you have sensors, etc. on your device? Are they part of your current measurements?</li> </ol><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/112811?ContentTypeID=1Wed, 29 Nov 2017 08:49:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8a361448-8ec0-490d-8ea3-e1482d6053a7yuyixuantai<p>Thank you!</p> <ol> <li>It is a custom board;</li> <li>I have no &quot;nRF51 development kit&quot;;</li> <li>I must modified example code first then run it in my custom board;</li> <li>I try to porting &quot;app_pwr_profiling&quot; example to my custom board , the current only 2uA .
