iPhone 15 Pro Max thinks charger is an Accessory?

My iPhone 15 Pro Max keeps giving me the message “cannot use accessory - this accessory uses too much power” but it’s for my USB-C wall charger, not an accessory. It keeps charging as normal, but the alert keeps going off every couple of minutes. I charge my phone at night and I’m a light sleeper so it’s pretty annoying. Any idea how to stop this?

It sounds like your iPhone is seeing the mains adaptor as an accessory which needs to be charged from the iPhone. This suggests it is an uncertified third party charger which does not comply with USB-C specifications.


My advice is to test with and use a fully certified and approved power adaptor and USB-C cable, ideally genuine Apple to eliminate all doubt about compatibility.

I am using the 20 Watt adapter that came with, I think ‘‘twas my iPad Pro, fully Apple certified product. The USB-C cord that came with my iPhone 15 pro max will not charge my iPhone. Just disconnects/reconnects over & over again. Giving me the error “this accessory uses too much power” I find it ironic since in the presentation it was boasted that since this cord had a braided design it would work “longer” & arrived broken. Would Apple replace this cord with one that works or am I just out of luck?

I have an apple 20w charger with the exact specs listed and receive the same error when trying to charge. I don’t get this message while using the MagSafe connector from apple plugged into a Belkin usb-c car charger. Can you explain why this is happening and what I can do about it? Several searches around the internet have only led me to find more and more people with the same problem. ****

I just spent nearly 2000 dollars on a IPhone 15 Pro with Apple care, and APPLE can't even supply a wall charger port to plug it into the wall. Was not told this when I bought it. WTF. And to think I was going to buy an Apple Air Lap top when the A3 chip came out and a IPAD to upgrade everything. Not now, totally ridiculous. Can I return it???


The Technical Specifications page for the phone would have told you, before purchase, what was included in the box: the phone, and a USB-C charging cable. The purchasing page would have told you the same thing and also emphasized that the phone would "not include a power adapter."


You might still be able to return the phone if you bought it from Apple and are in the return period, but it's hard to see how you can credibly claim that Apple was hiding the absence of the power brick from you.

My phone updated itself to 17.1.1 yesterday. A couple of hours later, I received this message. It wasn't plugged in when I received the message, so this isn't specific to charging. I have never seen it before on any iOS device I've ever owned. I have received it while charging as well.


For me, it isn't happening to the point of blocking things. It's only happened a couple of times. I find it hilarious because the only "accessory" is the Apple Watch I'm wearing.

You can add my Dad's iPhone 15 to that list as well. He updated it today, and hasn't received that message. I also checked with him, and he hasn't received it again on the iPad Pro. I haven't received that message again either. At the end of the day, these are computers, not appliances. At least on my end, it's probably just a hiccup if you will.


Thanks for getting back to me about it. If I'm suddenly getting it again, I'll post the additional information. But for the time being, everything seems okay.
