It can be seen that it is possible to reduce the energy consumption of sweat power from vdd
Chip is pcf2129
The current consumption will drop if CLKOUT is disabled. Also, the current consumption reduces with lower supply voltage.
With regards to the power management setting, the highest current consumption will be when PWRMNG[2:0] = 0b000 and the lowest current consumption will be when PWRMNG[2:0] = 0b111. See the picture below for the PCF2127 for the trend.
