Measure current consumption by the ST25R3911B on the X-NUCLEO-NFC05A1

I would like to measure the current consumption during the "Wake-up" mode with capacitive or inductive sense, and also during  the active rf-reads. Currently, the chip is powered by 5V and 3.3V. I am thinking to remove the 5V source and connect the Vdd to 3.3V as well. I can monitor the current coming from the 3.3V source. I should also remove the power LED to eliminate the current draw.

 

Anything else I am missing?
