Check out this blog-post by my colleague about measuring lithium battery voltage with nRF52.

Note that the terminal voltage is a very poor indication of % capacity.

@awneil: Feel free to suggest a better solution!

can i used fuel gauge/Coulomb counter to measure the battery life

Of course - that is exactly what they are for!
