My friend the other day told me she swapped out her iPhone for a new one because they checked her diagnostics. She said if there is anything other then i think it was awd-date in the diagnostics or something like that then there is a problem. Her new one displayed like 100 of the awdd-date in the diagnostics logs and she was getting more then 7 and a half hours on not even a full charge. She said her other one she returned didn't say the azd but something else and battery sucked. Mine has never showed anything like that and usually I only have tops 10 diagnostics about crashes and low memory. She had prob over 100 of just azd and nothing else. She said the guy at the apple store told her there doing a recall because something is wrong and there taking back iPhones no questions asked if it doesn't show awdd in the diagnostics. I dont know what the diagnostic means and neither does she. She just told me the genius told her this is what should be happening.
