https://devzone.nordicsemi.com/f/nordic-q-a/62479/decouplingHi, I use nRF51822 powered by CR2032 battery. Same decoupling as dev board PCA10001. Would you recommend different values of decoupling capacitors for battery powered devices to extend life-time?

With the nRF51 you should at least have an extra 10-100µF if not larger.&nbsp;<br /><br />I do recommend that you use the nRF52810 with its DCDC converter as you will have a much lower peak current than the 51 series and is fairly comparable in price. You will get a lot longer battery lifetime and shorter time-to-market.<br /><br /><br /></p><div style="clear:both;"></div>
