My iPhone 4S is not charging when plugged into clock radio. What's wrong?
So about a week ago, I docked my iPhone 4S into my Sony ICF-C7iP clock radio as I do every evening before going to bed. I bought this clock radio back in August and have had no problems with it at all. However this time, I noticed my phone was not charging. It didn't make the charging beep nor did it show on the display that it was charging. I tried removing it & re-seating it...nothing. I tried rebooting my phone which resulted in the same problem. When I plug my iPhone into either a standard sync cable or an iPhone dock, it charges/syncs as normal.
Suspecting the problem was with the alarm clock, I contacted Sony support. The clueless support rep on the other line suggested I return the clock in exchange for a refurbished one. For a $60 clock, this was more trouble than it was worth, so I decided against it.
I then decided to purchase an iHome iA9 which was sure to work. I just unpacked it and set it up. When I docked the iPhone on it...you guessed it...nothing. It is still not charging. The funny thing is that the iPhone will play music through the iHome with no problems. I had also tried plugging the iHome into a different outlet with no luck either. I am out of ideas. I am left to assume that for some reason, my phone does no longer like charging when docked on to an alarm clock.
Does anyone have any ideas or suggestions on how I can get this to work again? I recently upgraded to iOS 5.1 and honestly don't know if that would have anything to do with it. But the likelihood of 2 completely different clock radios exhibiting the same problem is virtually non-existent.
As mentioned, I tried rebooting the phone with no luck. Docking the phone to a standard charging cable plugged into the wall charges the phone fine. Docking the phone on an iPhone compatable dock charges the phone fine. Is the problem with my phone?
Thank you in advance for your assistance!
