Ios 14 fast charging not working

Hi everyone,

I had the same problem of no longer hearing the double chime sound when plugging in my iPhone Xr for Fast Charge, with a USB-C to Lighting MFi certified cable and a PD charger, ever since the iOS 14 update. Initially, I've found this forum and some other where the same problem was discussed, with no resolution however. Also, I didn't have the time to physically test if Fast Charging actually still works or not, until today.

Luckily, I own the above Fast Charging cable/s (USB-A to Lighting and USB-C to Lighting) and PD charger since iOS 12 and ever since I had it, I ran multiple 0 to 100% charges and made notes on the charging times which today I want to share with you to give a resolution on this trouble and maybe some of you will find it helpful as well.

Please find below my raw notes on the charging times. During the charges, I haven't used the phone but only to make notes on the charging percentage. All charges were started from either 1% remaining battery or absolute 0% (phone completely discharged). Optimized battery charging settings was/is also On (I don't know when it was introduced). And I haven't noticed any overheating on the phone or on the charger either.

You will find tests with:

-original 5W Apple USB-A charger;

-original 10 Apple iPAD USB-A charger;

-Power Delivery uGreen 45W USB-A + USB-C charger;

-original non-fast charge Apple USB-A to Lighting cable;

-uGreen Fast Charge MFi certified USB-A to Lighting cable;

I have a basic iPhone 12 and purchased from the Apple store the following cable: mophie USB-C Fast Charge Cable with Lightning Connector (2 m), Part Number Mfr. Part Number: 409903305, UPC or EAN No.: 848467095272. I've noticed that my phone randomly connects and disconnects while it's charging. It is only an issue with this cable, too. I have reached out to mophie but haven't received a response yet. Has anyone else experienced this? Is it because it's a "fast-charging" cable and not a standard cable? I'm surprised that this could be an issue with iOS and not the cable itself. Mophie is generally a good brand (in my personal experience) so I'd be surprised if I actually got a defective cable (still possible of course).

It's a little annoying because sometimes my phone will go the whole night without "re-connecting" and I wake up with an uncharged phone. Or, it does the connect/reconnect thing often enough that the phone doesn't reach 100%. :/

I still have this problem with Apple OEM 18W USB-C charger+cable on latest iOS with my SE 2020 since I went to iOS14. I picked up the new Apple 20W USB-C charger and it charges correctly.

It appears the 18W Apple USB-C chargers are now useless.

They're not "useless."

They don't support fast charging, but they will charge your device.

For example, if you plug your phone in overnight as most people do, you would never notice the difference between the two chargers you name, it would still be full by the time you wake up.

Welp- I received a repl cable from Mophie and it's doing the same thing. I have the 20W USB-C adapter I bought directly from Apple. From reading the replies here, it looks like it's doesn't matter if it's an 18W or 20W, same issue. Guess I'll need to chat with Apple.

I have a new iPhone SE and it does not change on the 18w charger, only on the normal 5w charger. That my personal phone.

The charger is fine because it does work on my iPhone 11 i use for business stuff.

When i plug the phone in, the charging Symbol shows for a couple of seconds but then goes away and the phones stopes changing.

i run the latest update of ios 14.

I have the same issue with PD 20W charger and USB-C to Lightning cable, connected to iPhone SE (2020) with iOS 14.4.2.

It's charging for few minutes and then stops for no clear reason. I have to unplug and connect cable again to restart charging.

Shame that bug like this exist in phone which supposed to be better than Android phones which have no issues with same charger and cable (3 in 1).

Quite strange; my recommendation would be to discuss your issue with Apple Support directly; if it is a software issue that will be the quickest path to a resolution:

Contact - Official Apple Support

Contact Apple Support directly as that configuration should clearly work.

Ok so I figured something out. The usb to usb-c with a quick charge usb block, fast charges faster than any of the newer combination of charging cords/blocks etc.

In my iphone xs max It doesn't work either, I thought it was from the charger but I also tried on an iPhone 11 and the same thing happens...fast charging is not working. Ios 14.0.1

My 8 plus will not charge at all after two recoveries and restores.
