Since getting the FORCED jellybean update this morning my phone has been using twice the amount of memory and draining my battery 2x as fast. I dont want this update and would like to go back to ICS as my phone ran better and caused less headaches. I have to turn off everything just to make it last for 3 hours. Before with ICS my phone would last a good 6 hours with use before it needed a charge. Is there a way to take Jellybean off or make it so it stops using so much memory?
