Q: iPhone 7 Touch ID not working when plugin charger

I just got my iPhone 7 about yesterday, and I had noticed that the Touch ID (fingerprint recognition system) does not work when it is plugged in on charge. The charger works perfectly fine and charges my phone and nothing else seems to be wrong with my 7. When I unplug it from charge the Touch ID works perfectly fine.  when connect my iPhone 7 to my mac with charger cable having the exact same issue.

iPhone 7, iOS 10

I actually just noticed this to.  I've noticed issues with Touch ID on my 7 Plus however I had no idea why.  I took it in today because of the screen and it's still not resolved yet.  Last effort is to restore the phone completely.  If that doesn't work than they will replace it.  When I saw your post, I tried it and Touch ID works when it's not plugged in but when I plug it in to my MacBook Touch ID does not work at all.  Very interesting, might be a software glitch within 10.  I'll tell Apple when I go back tomorrow to return a 3rd party lightening cable that does not work properly that I bought today.

    I have had this problem with both my 5S and SE models. After some experimenting, I determined that it depended on which charger I was using.

     

    When using stock charger and charging from a PC/Mac, I don't have the problem at all.

     

    Certified 3rd party chargers seemed to work, like my Nomad.

     

    When plugged into a cheaper USB chargers that I've had for a while for other devices, I cannot use TouchID. In fact, with one charger, even the touch screen does not work when plugged in! I suspect it must have something to do with the current; perhaps it's a sign of a defective charger and/or cable.
