TWI current is up to 2mA, is this normal?

Below is a picture of advertising event current waveform:

The TWI current consumption is upto 2mA, I change the peripheral from TWIM to TWI, the current is exactly the same, why?

Is this normal? Or can this current be lower?

Thanks

I just check the 0x40000578 value is 0x00000001 which mean the DCDC enabled.

Now  I am confused if this is not enough to guarantee the chip work as DCDC mode?

And the supply voltage is? And the output power is?
