Hi all, I've done a little searching on this problem with no luck. The first couple nights this did not happen, just started last night and this morning. When my phone is plugged into the lightning charger (ac adapter into the wall) about every 5-10 minutes it makes the sound like it was just plugged in and the screen turns on. This is incredibly annoying when trying to sleep. I tried replugging it back in, flipping the lightning adapter with no luck. Has anyone else experienced a problem like this? I was gonna test it out a little more when I'm home from work later and if no luck, I guess goto the apple store with it. Thanks!
