charging is not supported with this accessory

PROBLEM SOLVED!!!

I upgraded my iPad 1 to 5.0 and I got this message " charger is not supported". I tried the " battery doctor" app, it didn't work 2. Tried that whole turn of hold the key blah blah didn't work as well 3. Cleaning didn't work either. I knew my charger was an after the market charger so I gave it a possibility. So went to app store, since they already seen this problem the guy said its not the actual cable even it's after market, it's the actual charger that goes in the wall. He said " it doesn't supply enough juice" then he tried one from store to show what he means so $20 latter it works now. make sure you get the big charger with 10v not the small 5v one for phone ( even thought that's the one I used before and it was fine"

NimaVA, I'm not sure that what you wrote is factual. According to the schematics of authorized vendors the voltage of the USB connector is 5 V, and not 10 V.

My so called faulty charger and cord work correctly when charging an iPhone with a iOS version (7.0) higher than mine, but not mine (6.1). So I have to conclude that it is a software issue. One hypothesis that fits what my tests showed, would be that at one point Apple narrowed the parameters allowed by the sofftware to detect genuine vs counterfit chargers, only to have to back out at a later iOS release, after getting complaints that the threshold was too restrictive for some of its own production.

It took 20 hours in total to charge my iPhone with the "charging not supported" message, but eventually it went to 100%. Now the battery is holding up its charge as usual. This is one more proof that the cable works and that it is just the software version at fault: it decides to trickle charge rather than charge at full power.

What did Apple say when you asked them? (Hint: this is a user to user forum; Apple neither reads nor responds in it).

An iPhone will charge with any source that supplies at least 0.5 amps (there is no upper limit, only a lower) AND provides a signal that says the device is compatible with the iPhone. iPhones with the dock connector (pre iPhone 5) only require this. However, a dirty or damaged dock connector can block the compatibility signal.

iPhone 5 and later with the lightning connector additionally require that the cable be either Apple-manufactured or Apple-certified. That cable has a microcircuit in the iPhone end of cable that must meet compatibility requirements. As with the Dock connector, dirt or damage in the Lightning connector or in the cable will result in the "device not supported" message.

Come on, I just need charging. No microcircuits or anything of that kind. If the charger or battery provides a signal that it is compatible with the iPhone, why does the iPhone say the accessory is not supported (there's no dirt nor damage). Or did this change in iOS 7.

If Apple neither reads nor responds in this forum why do I keep getting these messages?

Because there are moderators ("hosts") who have the job of enforcing the Terms of Use of the forum. If you get a lot of these messages for posts that you make you must be violating the TOU pretty frequently. Most visitors never get that message. The hosts do not read the forum and do not read messages unless a Level 3 or higher participant brings it to the host's attention. That is the host's role. They are not engineers, have no input into product development, and are not told what is being developed or planned. BTW, probably 90% of what the hosts do is delete the thousands of spam messages posted daily.

A host will edit your post to remove content that violates the TOU of the forum if the rest of the message is not in violation. If the bulk of the post does not conform to the rules the whole post is deleted. Hosts go out of their way to avoid deleting content unless it has no value or is entirely out of place. But again, hosts won't even see your post uniess a regular participant reports it.

It won't charge without the microcircuit. It also won't sync, won't restore, and won't be able to connect to audio or video devices. Apple externalized those functions with the iphone 5.

Lawrence,

I don't think it has anything to do with the lightning cable, because the problem happens on earlier cables too, that have a lower number of contacts and do not have the microcircuit. If you go back one or two pages in the comments of this thread, in the earlier cable there are only 4 wires, of which two are for the 5V voltage charging feature, and two are for data transmission. So the problem does not reside with the cable per se, but with the software of the iPhone.

There are two different sets of issues. It is NOT software on the phone. If it were there would be millions of posts about it with 500 million iPhones in use. When the problem appears with dock connector phones it is almost always either a USB power source that does not have the required "compatibility" signal on the data line or a dirty/damaged connector on the cable or phone. You can easily find hundreds of posts saying that cleaning or replacing the connector fixed it. This issue has been posted about regularly since the original iPhone, so it is clearly not a software issue with just one version. Unless you believe that Apple has failed to fix a software bug for almost 7 years through over 2 dozen releases.

When the problem occurs with lightning cables you are guaranteed to get that message if the cable is not Apple's or from an Apple-licensed supplier. If it is an approved cable then again it is either a damaged cable, an incompatilble USB power adapter or a dirty or damaged lightning socket on the phone. The lightning cable that ships with the phone is more delicate than the dock cables that shipped with pre-iPhone 5 models, so at least some of the reports will be due to damage at the phone end of that cable that contains the circuit board.

Lawrence,

I have to disagree. First, I'm not talking about the lightning cable. Second, in my case it is a problem that appeared recently with a new release for my hardware. A range of charge parameters that is too narrow would mean that only soem users receive the message and others do not. This would explain why I have a problem and why not everybody has a problem, and why my cable and my adapter work with other iPhones (and other releases) and not with mine.

Wow!!! You are the man!!! Searched so many sites but this has helped. Plug iphone in your original iphone cable connected to the PC (windows 7 in my case). "Not compatible" error shows up. Enter Windows 7 sleep mode. Charging starts! When you log on again in windows 7 everything is fine!!! Thanks so much for sharing this!!!!

When it is charging the voltage drops and when the Lightning cable has too much resistance the phone draws too much power this invokes the error message. I don't know how high the voltage can be, but I think it is 30 V.
