NRF52840 Coincell battery life

[PAWAN JOSHI]

My NRF52840 based module BT840 powered by one Coin cell  with 5sec.on and 5sec. off  with battery life of 22 hours .
Can you help us in extending battery life ?

Thanks

So what measurements & analysis have you done to find what's using up all your power?

What steps have you taken in your design to minimise consumption?
