Hi,

The CPU current is the run current of the CPU. Ideally the CPU will be in idle/sleep mode most of the time. The system ON current is the base current when the CPU is in idle mode. In this mode, chip can wake up on events from all enabled peripherals, for instance RTC/TIMER/etc. This mode can be used together with softdevice to maintain BLE advertising and connections. These currents are instantaneous currents, and depend on which mode the chip is in.

The current you see in the Online Power profiler indicate the average current of the chip, for a given task. The main contributions to the average current is the RADIO currents, when transmitting and receiving, and the CPU current when softdevice is preparing/processing packets.

Best regards,
Jørgen
