Would like to point out that you need to use the cable included with your iPad 3. It's slightly thicker gauge than that of the previous 30 pin cables and can deal with the resistance of charging the bigger battery. It's pretty noticeable when you hold the two cables up side by side. I was having this problem but then I held the cables up to one another and saw the difference. Not only did the not charging icon disappear but it seems to be charging slightly faster.
I think the point you make is absolutely correct, I have checked that out regarding the cables, certainly makes sense. I have 4 or 5 cables and 3 Apple 10watt chargers here, and 1 of the chargers was purchased from Ebay a few months ago and is supposedly the genuine Apple product, same with 3 of the cables. The problem is because they all look identical I may have mixed 2 of them up. However I do know which is the charger and cable that came with my iPad3 and I definately wasn't using it at the time, I've now labeled it so I can easily tell in the future. I suspect it was the charger or cable combination that likely came via Ebay :-(( genuine or not.
At least I'm hoping it was as simple as that and nothing else, AIS it's charged twice okay since. One thing I have noticed during these last few days is that the length of battery time certainly improves quite a bit after 2 or 3 full charge cycles.
You are right though, as I wasn't using the charger and lead that came with my iPad 3 when the charging stopped 2 or 3 times before it got to 100%.
I thought I was using the charger which came with our iPad 1, but I wouldn't like to guarantee it's a genuine Apple cable, AIS they look the same, but I've run the battery down twice since and recharged with the proper iPad 3 charger and cable and it charged up to the full 100% without any problem at all.
Just to confirm.. does the cable that came with your iPad 3 have " Designed by Apple in California Assembled in China" printed on the side of the cable. ? like the original chargers have.
I have 3 cables with it printed on the side of the cable, 2 will be from our iPad 1 and iPad 3 and the other from my iPhone, the other 2 however are blank with nothing printed on them.. so I'm suspecting these 2 are the Ebay allegedly genuine Apple items. ;-)
Also, you are correct the iPad3 cable is indeed slightly thicker.
Thanks for the reply..I appreciate the input..
