Power supply voltage for nrf52 SoC

Does nrf52 SoC consumes the same current at different supply voltages(assuming similar operating conditions) ? For eg what is the difference between operating the nrf52 at 1.8V or 3V for current consumption?

In my design I am using a li-ion battery to power NRF52 SoC at 1.8V. Some of the other logic require 3V. So does it make sense to use 1.8V for NRF52, from a power savings point of view??
