Some USB-C Power Banks Fail to Work With iPhone 15

That proves nothing. I suggest you take a picture of the iphone AND the charger in the same picture showing the charge symbol on the iphone.

What would I gain lying about it? I suggest you take a look below at Post #41 in this thread before you chirp... 🥴🤫

Anker with 2 of 4 lights (assume 50% charged) is charging 89% charged iPhone.

No, Anker is at fault, not Apple… 🙄

Oh please don't leave us with a cliffhanger! Surely you're going to explain why it's Anker's fault? Is it because the same problem exists on the myriad of Android phones (all of which also use USB-C)? Is it because the iPhone 15 existed when Anker developed their power bank and should have tested it (sarcasm, because Anker could not have tested but on the other hand, Apple COULD HAVE TESTED)?

This is very easy to understand. If the powerbank's port serves as both input and output, without a software command, how would the powerbank or iphone know it's supposed to receive or give charges? These powerbanks work perfectly fine with other devices, because 99% of devices out there only receive charge.

Weird, then what’s this article talking about? Is it charging consistently as far as you can tell?

From what I can tell, mine is charging consistently. Pictures from a few minutes ago. Including the Anker model information as well (Powercore Slim 10000 PD).

Post #41 also shows the power bank with lower charge (50%) charging iPhone with 89% charge.

This is occurring with my Anker 20,000 mAh PD power bank. I've tried various USB-C cables but it just alternates between charging and not charging. USB-A port works, but is probably way too slow.

My Nimble 5,000 mAh power bank works just fine.

Lots of issues seem to be popping up with USB-C lately. Wonder how many more stores we're going to see about USB-C not working correctly for whatever given function. Superior connector my ***. Maybe the EU should've kept their noses out of it instead of mandating this crap.

This sounds like an Apple design issue.
Note: I do not have an iPhone 15.

I have several power banks (Cali brownout and earthquake preparedness) and use Android and Apple stuff. Along with Windows and Mac. All but my iPhone use USB-C. I buy the higher capacity cables.

Can't say I have had any of these, including iPhone not work with a powerbank. Knowing this, it tells me this is an Apple design issue, not a powerbank issue or a USB-C issue.

USB-C Ports on PowerBanks can be input or output.
Apple may need to add a Setting to have this feature be either: Auto, Change (get charged by another device) or Charger (charge other devices).

Every device should have this function, really. USB C is so finicky with connections like these, powering things off, changing which is plugged in first, none of this should ever have happened.

And therein lies the problem. People think USB-C is standardized...and they are both right and wrong about that. The shape of the plug...yes, that's standardized. The capabilities of that cable...not even close. I have multiple USB-C cables in my house and I'm pretty sure each and every one of them has different specs and what works and what doesn't. If people want "standardized" cables...USB-C definitely isn't that.

The EU wanted to throw its power-hungry weight around and it's leaving us with problem after problem now. The EU did what governments do best: take something that worked just fine...and break it. It really seems like with the more things the EU forces...the more the quality drops. This is what happens when people who don't understand technology try to regulate it. Things might be different if they actually had to fully understand the things they want to exert their power over instead of just throw their weight around because they like making rules and don't know what else to do.

This is why Apple gives you a USB-C 2 cable with your 15 Pro/ProMax instead of USB-C 3. :rolleyes:

You can simply use the usb-a port with a older usb-a to usb-c cable im sure you have one lying arround, iphones don't reach 30w anyway so don't fuzz on the usb-c pd port, that is just wierd trying to charge your phone fast if it can't go fast, usb-a is otg so it have to charge, usb-c is reversable,

yeah, just I wanted to be able to charge multiple devices on a trip, I have the 15 pro max and a 15 pro...

Oh, are you claiming that we haven't had these issues with USB C before? The big difference here is that now it will get headlines.

Yes. Never seen it, never heard of it. I've been through over 50 chargeable USB-C devices in the last decade. Never had this problem.

There have been other issues such as slow speeds, some devices only charging with the cable plugged in one way and not the other, but, never something as laughable as this. Apple's latest polestar device unable to negotiate PD direction when everyone else (including dirt cheap devices) can and have for a long time!

Have that exact model listed in the article...mine is charging without an issue via the USB-C on the Anker 🤟

I also have this model and just tested it this morning. It charges the iPhone just fine. I used the cable that came with the phone.
I was going to post a picture of the phone charging but it’s set to 80% max so it flashes charging and then stops.

So you have on both sides one USB-C port which is an in AND output port. How should they know in which direction the current should flow? Percentage of battery capacity? But maybe you want to take a charge from your power bank even it’s already at 20%. I think you need such a switch.

This is not Apple’s problem and they have no need to test anything. Apple have made the iPhones totally compliant with the PD spec.

Anker has configured some of their cheaper power banks assuming that most phone makers won’t implement the bi-directional aspects of the spec - which most Android phones don’t.

Anker knows how to implement this properly, which they do on their more expensive power banks, including the one I own which is pictured below - with clearly labeled input/output ports.

What other devices negotiate PD direction?
 
Apple will come up with USB-C certification process to milk money. You have to buy an Apple mi-fi certified USB-C power bank to charge your phone. Apple will sell their power bank for 199$ a piece.
 
Just tried my Anker Prime 20,000mAh Power Bank (200W) w/included 100W USB-C to USB-C charging cable and it worked on my iPhone 15 Plus.
