Is anybody else encountering this issue? Mine takes over twice as long to charge than before. The phone was initially off when I started charging from 13%, then a couple of hours later I checked and it was about 55% when I turned the phone back on to do a couple of things. I put it down, still on but with no mobile or wifi enabled, and it continued to charge at the same slow rate. I used the wall charger that came with it, in the same wall outlet I always use. I even changed to another outlet, but same thing. It's definitely related to the JB update.
