Wifi was shut off by itself. Had to go back in on both of our phones and re enter the passwords. We had Wifi enabled on both phones,but it would not show available networks even when turning it off and back on. Had to go to Settings and re do it.
Phone has VERY low battery life now. 2 Hrs and 42 minutes on battery power. Used to be all day. Don't rely on it as an alarm clock!
Phone jumps from 40% power to 6% in a second and shuts down.
Phone shuts off by itself,and restarts several times.
My phone was doing the same thing a couple of weeks ago. Have you tried the spin test on your battery? If you place it on a flat surface and it spins the battery is bulging and needs to be replaced. I had to replace mine about a week before JB came out and my phone will last well over 36 hours with a new battery and seems to last even longer with JB.
