"This accessory may not be supported."

Ever since updating my iPhone 5 with the new iOS 7, this display message pops up while my phone is plugged in to the computer, using the original cable that came with it in the box. Researching this issue only informed me that the new iOS is no longer compatible with generic iPhone chargers. However, mine is the one made by Apple and so there should be absolutely no issues with it. While it is plugged in my phone charges on and off, never consistently charging. It's really irritating and is making charging a very slowgoing process. Does anyone else have any insight on this issue?


While we're at it, I noticed the new iOS 7 kills the battery life much faster than the previous iOS; I don't use my phone too much throughout the day, and it has been dying consistently twice a day. If I don't use it nearly at all, it seems to last only six or so hours.


Thanks in advance for any feedback! Hope not everyone is having these issues!

There are several conditions under which you will get that message. All of them have already been documented in this thread, so you could find them just by reading it. But here they are anyway:


  • You have dirt, lint or moisture in the lightning connector on the bottom of the phone (most likely cause)
  • The cable is a counterfeit cable (meaning it looks like an Apple cable, but isn't)
  • The cable is 3rd party and not certified as Made for iPhone (MFI)
  • If it is a genuine Apple cable, or one certified as MFI, it is damaged internally
  • The USB power source that the cable plugs into does not meet USB power standards
  • The connector on the phone is physically damaged

So the first thing to check is the connector on the phone, with a bright light, magnifier and a non-metallic tool to clean it like a toothpick or a cotton swab stick with the cotton tip cut off.

Lexiphillips - you're not crazy - I have the exact same issue - brand new cable and adapter from the apple store when I got my iPhone 5s, it always says "this device may not be supported" and doesn't charge when connected - and that is true for both of them! And if I unplug my phone, my battery goes from 100% to 50%, with no use at all, in about 4 hours. After some research it appears that ou pretty much have to turn off everything except wi-fi - cellular data, all apps that might use data ever - and then hopefully the battery usage will increase. This is not good. The whole point of cellular data is supposed to be to have and use it - not for it to come with such an enormous penalty.

Not sure if anyone has already noted or realized this, but the extenders DO work when used only with the electrcial adapter to charge a phone from an outlet - the problem seems to be that they DO NOT work when plugged into a cpu to charge or update the phone. This is a problem for sure - but at least you can use it to just charge a phone from an electrical outlet...Apple definitely needs to make good on these. I plan to bring mine into the store and see what they say/do...
