Why is my S4 constantly restarting for no reason at all

My phone is just over a year old(1 month past warranty of course) and it has recently started to reset it self over and over it doesn't matter if it is on the charger or not even when I haven't used it in several hours and it is just sitting on my desk it will shut off then restart yesterday it did it three times in an hour and I hadn't touched it WTF

I think it's a software issue.....
my friend's phone used to show charging and discharging even when it's not plugged to the charger and used to restart unexpectedly... hard reseted it... ran smooth for two weeks... problems started again... gave it to the service centre,changed the OS... updated to lollipop... problem solved...!! But many features of jelly bean will not be in lollipop and sometimes apps shuts down suddenly and comes back to main page... I THINK U SHOULD UPDATE TO KITKAT OR JELLY BEAN ITSELF....
