My iPhone (12 pro max) doesn't connect or charge with PC but it charges fine by the wall charger.

Hi,

I've been using my laptop's type C port to charge & transfer data between my iPhone and the laptop ever since I bought it. And it worked without any issues.

But now the iPhone doesn't show any response at all when I connect it. Nothing shows up in the device manager either. I tried restarting both devices. And I have tried everything on the support forum. no luck! :/

The iPhone charges fine with the wall charger by the same cable.

Diagnostics from iTunes while the iPhone is connected.

Hi Judy,

I finally found a fix. Thought I should post it here in case someone else encounters it as well.

The problem was from the laptop's side. Due to some reason, the USB C port wasn't getting any power. So no connection was being established. The fix is :

- turn off the PC

- disconnect all cables

- press the power button 30 sec (to reset the USB-Cs - the PC will not turn on)

- connect charger and turn-on the PC normally

The iPhone can now connect & charge like before. This is all I did and it fixed the issue.

This is the article where I found the fix: https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/USB-C-port-suddenly-not-working/td-p/6151817/page/2

Thank you for trying to help 🤍

Good afternoon sheryartahir,

Welcome to the Apple Support Communities!

It sounds like your Windows PC is not recognizing your iPhone 12 Pro Max. Since there was an update to iOS today (May 24, 2021), we would suggest ejecting the iPhone from the computer.

Check to see if there is an iTunes for Windows update for your computer and restart it to refresh after updating.

Update your iPhone to iOS 14.6 and restart it to refresh as well.

Then try connecting your iPhone to your PC again.

If the issue persists, please reply to this thread and we'll do our best to help you!

Take care.

Hi,

Thank you for the reply.

I updated my iPhone to 14.6. While iTunes is already updated. I've installed the latest windows update too.

Restarted both devices as well. Didn't get anything, same as before.

I'm not exactly sure (just a guess) but I believe the issue started after I updated my windows a few days ago.
