IPad not charging
My iPad sometimes charges fast, sometimes slow (only a 10% increase in charge level over night), and sometimes not at all. In fact sometimes it seems as if plugging it in is actually draining the power from it.
I am plugging it into the mains, not a PC, and I am using a proper apple charger. It always says it’s charging.
I have tried restarting it (sometimes that works but not always) and have exited all the apps that were running.
Yesterday it was charging fine while playing music, but it then crashed out during playing a track, restarted itself, and then had the charging problem.
I suspect it’s software rather than hardware since the problem is intermittent.
It’s an iPad 1, now a year old.
Any thoughts? I can’t be the only one with this problem, surely?
