Charging (or LED) problem

Since the latest phosh update, I have experienced a problem with charging:

When I plug in the phone for charging, frequently nothing seems to happen - no LED, no power up (if the phone is off). A couple of times I’ve brought it back with the Evergreen charge troubleshooting procedure, but sometimes that does nothing at all.

Just now, the same issue occurred, but I left the phone plugged in anyway, despite having no indication that charging was happening. I checked it several minutes later and the LED had finally illuminated, indicating charging. I powered it up, and confirmed it was charging.

I sometimes charge the phone after it has been in use for a while, and therefore warm. Sometimes I charge from “cold.” I think the problem has occurred in both modes.
