When I plug my iPad into charge it constantly beeps whereas in the past it just beeps once.

Hi Lindsay0810,

If you are having charging issues with your iPad, you may find the following article helpful. In particular, if you are having recurring beeps from your iPad when charging, you may want to check you cable connections and possibly try another cable/charger if available to see if the issue persists.

Probably a dirty connector and/or bad cable. Try cleaning the iPad's connector.

I had this problem and, after reading this thread, I removed the USB extension cable and plugged directly into the USB port on my iMac and the problem disappeared.

Hardware: iPad Air 2 and iMac 27-inch, both purchased in November, 2014.
