USB C connects but does not charge iPhone

[bonebrain]

Anyone have this happen. I have a 2017 Macbook Pro 15inch. The USB ports will communicate but for some reason will not charge anything. I have reset the PRAM and the SMC and nothing. Not sure what is going on. I have the mac plugged in and fully charged

It's likely not the computer or the iPhone. Try a different cable or adapter.

Thanks I tried a couple of cables as well.

Will it charge other devices? I think that you can get a device that measures power output on USB ports but you could just try another USB device that you have handy.

Tried a few things none will charge. But they can communicate. I backed up my iPhone

Sounds like a hardware problem then - bring it in and see what Apple says.

I'd get an Anker multiport charger for charging things. It's nice to have 12 and 18 Watt charging ports.

Don't think I saw this in the thread, so, apologies if wrong:

What charger are you using with the Mac?

In my case, I have a two port charger, USB-PD and USB-A. When both ports in use, the PD port gets throttled, and if my USB hub is plugged in, not enough power going to the hub to power accessories plugged into the hub.

This sounds like a cable issue. I know you tried different cables, but were they reputable cables?

Does "regular USB" devices charge? Meaning non-Power Delivery aware targets? It is possible you're failing to negotiate for Power Delivery due to a faulty set of cables.

Apple can test it though as they should have a C to Lightening cable they make on hand.

Looks like I had 2 bad cables. I found one that works. Ugh, need to replace them regularly I guess.
