USB C on iPhone 15 not working

For the PD negotiation, to fast charge, it needs a minimum of 18W (20W) preferably (and obviously the chair will need to support Fast Charge).

Otherwise anything from 5W will charge, albeit slowly, in non fast-charge mode.

However, there is an issue with Apple’s PD negotiation and sometimes with 18W it won’t draw any power at all. (When I was in the store they couldn’t get it to charge on their own USB-C set socket connection, to replicate the issue I was having at home). Apple are currently ripping out the guts of my phone out and replacing it to see if that can rectify the issue (as it should be able to go into fast charge at 18W OR go into normal charge mode. However there’s some issue in the iPhone 15 that’s preventing that)

I'm having the same problem now too. Won't charge with USB-A to USB-C cables(Belkin & Anker). Only works using USB-C to USB-C to cables. Won't even charge using a Asus 45W laptop charger. Just annoying.

I just purshased a new iphone 15 pro. In addition to the usb-C cable that came with the phone, I would like to use my many USB to USB-C cables at home I have been using for adroid devices. Using the same adaptor that came with an adroid device, only two out of five cables can charge the new iphone 15 while each and every one of them works for android devices. Can some one explain?

If the iphone 15 indeed has much narrower tolerance for accesories does it mean we can only order them from Apple store? Is this a commercial strategy or technical necessity?

The flip of this, is the reason Apple have had to move to USB-C is because a legal directive as part of the single charger reform (aimed at reducing waste and costs) for all small electronic devices to be comparable with USB-C charging ports by Dec 2024. The European Commissioner has already written to Apple, before the iPhone 15 came out, telling them that if they restrict the functionality with 3rd party cables they will look to ban new Apple devices from sale after this December deadline.

So with that in mind, if the cables work for other devices - they should be working with Apple too.

HOWEVER, the current place I’m at with Apple is that it appears that the “Power Delivery” Functionality seems to be troublesome and is giving some users over USB-C to USB-C issues with none charging. There’s a handshake process over the cable between a PD capable power source and the iPhone - and the iPhone isn’t always confirming this handshake properly and is stopping the charging process. (Software support are blaming Hardware, and I’ve had a new inner system - yet is still having the same issue. And now Hardware support are blaming Software and no one knows how to fix it)

Just because a cable has USB-C connectors does not mean that it is Power-Delivery-compliant.

A cable that is must have chips to let the attached devices know that it is. So the Power Delivery negotiation process is affected both by the two devices (including any bugs or quirks they might have) AND the cable.

In the absence of a PD-compliant cable, only 5V charging (assuming the iPhone 15 supports it) would be available.

Apple have said, becuase of the legislation even if a cable is not PD compatible, the phone should be able to charge in non-fast charge mode. As it is must be able to charge with any USB-C to USB-C, even if it charges slowly to meet the legistlation.

(In my case, even a new Apple own cable they picked off the shelf replicated the same issue)

I’m having similar issues. I can’t use my Apple CarPlay charger ( type a to type c). It works on and off. If it’s working and I hit a bump or the cord moves a little it stops working, so for a while I thought it was that cord. Around the time this started to happen certain cords I have at home stopped working altogether. I only have two cords now that work and one of them is the one in the car that works on and off. I can’t use my other cord in the car, because my car doesn’t have a type c port for CarPlay. This just became an issue over the past few weeks or so.

Just weird. Managed to charge with a Mcdodo brand USB-A to USB-C cable. Other brands just doesn’t work. All USB-C to USB-C is fine. My Anker(A to C) cable is just about 1 years old and charges my other devices fine. Why is this happening? lol

What year is your Seltose Rajhans? I have a 2024 Kia Forte and I can only use CarPlay wirelessly and not through a cable oddly enough so I just use a USB A to USB C cable in the car for charging only.

also what is a boAt C A 750 cable?

I just bought a new iPhone 15 Pro. And it was charging fine on my Samsung charger (the 25 W port) and a standard cable (not the one in the phone box). Suddenly now today it will not charge. However, there is a 15 W USB port on the same charger. And this one (still) works. I realize that the problem started just after the last IOS update a week ago.

I have the same issue with the official original cable. iPhone 15 sucks. I updated the software. Did a hard reset. Nothing works. I’m travelling and my phone is close to dying. What the heck am I supposed to do? Garbage phones.

Look up «Batteries and charging» under «Settings». If any of the settings are on (optimized or 80%) delete them (no selection). Then try. It worked on my 15 Pro when it did not accept third party chargers.

Same same same. Iphone 15 pro v17.4.1

I sent back a highly recommended surge protector I thought was defective due to the USB-C port. Replacement arrived. Same issue. Tried everything mentioned to no avail. Tested on chargers, different cables, all other devices would charge. I dug out an extra long apple cord that came with my MacBook pro and it started charging. Not sure how long it will start this way but at least I got one full charge! 😀

That didn't work for me. It's so odd how some solutions work for some but not all, and differing solutions worked for others but not all. It's a crap shoot with what works and what doesn't. The issue really lies in this last update IMHO because it was charging fine prior

I’m currently having this problem, I’m contemplating filing a claim with apple to see if there’s something wrong with the port itself. It’s annoying, I’ve resorted to a MagSafe charger to avoid this problem.
