Power supply problem of my ID Card (German NFC secure chip?)

[IK6yae0s]

Yesterday I tried to use my ID Card with my CC and the AusweisApp.
The ID Card NFC chip is found but If I tried to start the security functionality of the card the connection will loose.
I position the card over the camery module because I mean the NFC antenna of the CC should be there. But also moving the card around this area does not fix the issue.
The knowledge base of the AusweisApp means this could be a problem of limited power supply for the NFC because of power save functionality.
Is there a way to modify the power supply to send more power to the nfc secure chip in my ID Card?

Hello,

after first initialisation of id card was done on my workstation the id card could now be used also on the communicator with ausweisapp without any more problems. I'd read that the card needs more or longer power which maybe cannot delivered from the phone. Signing later looks like limits the power so it works now.
