Around every 10-30 seconds my IPhone 4 automatically lights up (when in lock mode). I believe it is doing it whenever my 3G service (AT&T) changes its signal… i.e. goes from 4 bars to 3.but i am not sure if that's the problem.It is really killing my battery horrifically and i would really like help.Is there a setting to stop this or does anyone know how to solve it?
