This should help people who are experiencing slow Wifi issues with the iPhone 5. It’s a frustrating problem that several people have complained about. I’m thinking that by recreating it in the video as I have, it should make it easier for Apple to patch.

What you basically need to do, is download something in the background in order to get full download speeds for whatever you’re doing. I have also been able to get full speeds while I’m mirroring through Airplay. I’m wondering if the device throttles the wifi speed to save battery unless in high demand. Anyways, hopefully this helps someone out.
