It’s absurd, as a microcontroller. Like ~300mA max which is like 1W. Though only in short bursts if planned wisely, and also there are worse ones. I believe Nordic nRF does 2A bursts that are to be taken care of by a larger than usual bypass cap.
That doesn't sound right... all of the Nordic designs I've seen have been exceptionally low power. The internal LDO / DC-DC blocks for running directly off of a battery are sized for <100 mA. Even with bypass caps, 2A spikes seem like the wrong order of magnitude for a chip that can run off of a coin cell.
I have an nRF52840 design, and I've never seen it draw more than low ~tens of mA during BLE transmit spikes, even at the maximum transmit power setting.
