Question: ipad slow charging
I had this iPad model MD510B/A for over 2 years and have had no issues up to now. Having recently updated the software to IOS 10.3.3 I have noticed that the iPad no longer charges as fast as it did. For example, this morning, it has charged from 26% to 43% in over 3 hours! I have always used the approved Apple charger and cable direct to the mains. I have changed the cable but with no effect and the lightning port is clean. I only use the iPad to do occasional emails and internet searches so is not over-used by any stretch of the imagination. Have any other users experienced similar problems and are there any solutions?
MacBook Pro, OS X Yosemite (10.10.3)
