iPhone touchscreens on Class 800/801

I used an anker cable and charger and the charger seems to have got scorch marks on the pins afterwards (I’m not sure if the scorches happened definitely then but it would seem likely)

Scorch marks have nothing to do with socket grounding, which is the issue here.

Poor form from LNER customer services. ”It’s you not us”

I wasn't impressed with the response!
It's fine on diesel, but as soon as it's on electric, that's when the problems start.

Agreed, seems more likely poor contact in the socket causing arcing than an RFI/EMI issue.
Another potential cause that's quite common is when you get a spark whilst plugging an adaptor/charger in as the filter capacitors quickly charge up, that naturally can cause burn marks after a while with all the plugging/unplugging. It's a good reason for having switches on a socket as they make/break connection much quicker than someone plugging/unplugging the item.

It wasn't fixed on the Azuma I travelled on this afternoon. or the one I travelled on last Saturday.

Was the Azuma where you didn't experience the problem running on diesel?

Nope, it was 801222.

I have a Anker PD power bank.....so I never have to plug my expensive phone or tablet into any dodgy train sockets .....and reading this thread, I certainly never will.
