Yes, could be an option. On the other hand, I have more the feeling that somehow the AD converter gets started but is not stopped or some other things like counters, muxes, etc. are running or set and keep drawing power because they are not reset. --- I have no clue what I'm talking about, but trying to understand hardware as can be seen at http://www.espruino.com/STM32+PeripheralÂs makes me fish in that murky pond... I know that an NRF52 is not and STM32, but I expect similar 'intestines'; they are both ARMs after all.
