Phone charging on Swiss trains

Is there any provision for charging phones on Swiss trains?

Hi kapurpranay ,

It is pretty rare here. I have seen them from time to time but not often and I would not count on having one for you to use - just be pleasantly surprised when you get one. :)

it was available on 50% of trains on which i travelled

but it is always advisable to have a power bank along

Thanks

The Gotthard Panorama Express has this handy arrangement (photo attached). I don't recall seeing charging facilities on any other trains.
