If i move the power supply cord it turns off and i have to run the power cord under the console for it to stay on

i have the same phone . it helps if you restart it at least once a week and also install a cleaning app to clean up the memory and get rid of any unwanted files like the cache and turn off your WiFi and Bluetooth and other wireless functions as they drain your battery fast and can also really slow down your phone because they put a drain on its ram (random access memory) . the apps i use are Du battery saver for my battery and mobile optimizer to get rid of unwanted files and clear cache. i also have all my music and pictures and other files like PDF's on my micro SD card
