Odd charging pattern - depending on the current charge
I have the original iPad 64Gb, with 2 original Apple iPad mains charging cables/plugs, plus an array of third party cables (non Apple verified) that I use plugged into my PCs (home and at work).
Before iOS5 I didnt have any problems charging with either the two Apple cables plugged into the mains, or the third party cables plugged into the computers (trickle charging).
However since the upgrade to iOS5 I am having problems with the Apple cables. If I plug in when the iPad charge is below about 25%, I get the standard 'Charging is not support with this accessory message', and I have to go and trickle charge on the computer. Once above 25% or so, I get the 'Not charging' message when plugged into the Apple cables, but the iPad does trickle charge. Once charged to around 60%, I can disconnect the cable and when reconnected the Apple cables work properly. It is very odd.
I have done a system restore/re-install but that makes no difference.
I know Apple have an update to iOS5 in beta that addresses some charging issues, but until that is released was wondering if anyone has any suggestions.
