We have a classroom with 7 iPads. When all are in use, multiple students seem to have there connections dropped and devices freeze up. The devices are up to date and the teach closes all tabs and apps at the end of every day. One device (new one) is depleted of power very quickly (while the others are at 75%). Is is possible or likely this iPad is the root of the problem? Could it be losing power so quickly because it is having difficulty communicating with the Wireless Access Point (like trying to resend packages)? Could it possibly be creating so much traffic, that it is affecting the other 6 device?
