Hi Franshee,

Generally the key to low power designs is to disable everything you don't use when not needed, particularily anything that needs the HF clock. The (old) Optimizing Power on nRF52 Designs blog post gives a good introduction, and covers some nRF5 specific tips. If you are using the nRF Connect SDK, Power optimization has a lot of good information.
