It sometimes happens due to deteriorating cables or a bad connection from a drop. Can also occur from using non apple equipment for charging. Could also software too. Best bet is plug it into the computer and hold both the power button and the home button down together until it reboots and keep holding home button. Try to restore it. That will let you know if it is a hardware or software issue. Hope this helps!
