iPhone flicking between charging and not charging

[kaicrawf]

My iPhone charges fine when using the mains power, but when I plug it into my MacBook it keeps rapidly saying it's charging and then not charging. I need to sync some things to my computer and it's obviously not staying connected so it's not going to work ://///

(I've tried different models of iPhone, such as iPhone 4S and iPhone 3GS)

Any suggestions are appreciated!

I've seen several bad cables cause the alternating connected/disconnected problem.

I'm using an official Apple cable though :/

If it's one of the "official genuine real apple" cables from Amazon or Ebay, I would definitely suspect it. If it's really an apple product, I would still be suspect because I have seen this happen many times and it was always caused by a cable.

x2 ... I've had 3rd party cables do this. The only time I've seen an Apple cable do this was in a relative's car --- the cable was frayed so bad it had bare wire exposed. They had to hold it just right for it to charge......

If it is an Apple cable, take it in and tell them what is happening and they will likely replace it for FREE!

Is it the same cable as used to charge from the outlet? If not, try that one to see if you experience the same thing or if it's better (this would help figure out if it's likely the cable or not).

I've had this happen before because of using an old iPod plug. Could be the adapter.
