https://devzone.nordicsemi.com/f/nordic-q-a/4024/nrf51822-mkit-power-consumption-about-18maMy Board PCA10024 (nRF51822 Chip QFAAG0) consumed at least 18mA with external 3V battery. The nRF51822 chip itself consumed only 5uA in sleep mode. What&#39;s go wrong? So a real test with coin-cell battery makes no sense.
