https://devzone.nordicsemi.com/f/nordic-q-a/19728/nrf51822-sleep-mode-power-consumption-2maI am using nrf51822 with soft device s130.I used sd_app_evt_wait() to enter the sleep mode and i disabled all the peripherals before enabling sleep mode.According to the datasheet it was mentioned the module in sleep mode when peripherals are idle theen-USTelligent Community 13Thu, 16 Feb 2017 04:48:13 GMThttps://devzone.nordicsemi.com/thread/76760?ContentTypeID=1Thu, 16 Feb 2017 04:48:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:60b040ee-2a18-4724-b5f0-0bc13d834777Roger Clark<p>Did you check that the device is not still in debug mode ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/76759?ContentTypeID=1Thu, 16 Feb 2017 04:37:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d05b936e-e9b0-4723-ba43-b8e2151a3f9eRaghu GS<p>Thanks for the response. I am using UART,I2C and Timer. But before going into sleep mode I turn off all these peripheral.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/76758?ContentTypeID=1Wed, 15 Feb 2017 22:30:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:76aa38a7-cc0e-464f-a708-57fa6981781eRoger Clark<p>Still in debug mode perhaps ??</p> <p>PS. There are plenty of previous questions and answers to precisely this question. Have you checked to see that your question is not a duplicate</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/76757?ContentTypeID=1Wed, 15 Feb 2017 16:35:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c3e7968a-928f-4449-9070-c72bbeecce1bKeton<p>2 mA is way too much. What peripherals are left running when you enter sleep mode? I bet that one of high power consumption ones (UART/SPI/I2C/PWM/TIMER) is on.</p><div style="clear:both;"></div>
