My S4 is turning off by itself, I was wondering if it's the power button?

S4 not turning off by itself and not charging

Try using a different battery and see if it's just a case of the old one not being able to hold a charge. When there's a little bit of charge left in a battery, the phone still will boot up but only for a short while before shutting down again. Do a process of elimination and try new charger and/or a new battery to determine where the faulty component lies.

If the phone is not turning on, then there can only be two possible reasons here:

  1. 1
    "Battery".
    As per mentioned above that you need to try to use a different battery if you have spare or from a friend and see if it does the same issue for isolation.

  2. 2
    "Phone hardware".
    If you have tried another batter and it works fine without any problem, then there could be a problem with the hardware that must be check it internal components. Something might have trigger to cause this problem.

If the phone is not charging, it could be the charger or the phone it self. You can try to plug the phone to a computer via USB and check if its charging or not.

You can power-off your Samsung Galaxy S4 without using your power button by using a third party application called "Button Savior". This app is very useful in case you have a broken button on your phone. To know how to install and use this app on your phone, please read "How to switch off Galaxy S4 without using power button" in this wiki.

How can I turn on my Galaxy S4 Active without using the home button?

I purchased a Galaxy S4 Active and after purchasing it I was told that the charger port on the phone did not work so instead I would have to purchase a "battery charger" to charge the phone. After a hectic day of finding a charger and buying one I charged the battery ALL NIGHT until the battery was fully charged. After fully charged I put the battery in the phone expecting it to turn on finally, well it won't turn on now. I do not know what to do. I'm hoping very highly that it is just the power button and not the entire phone being messed up. Can you please help me?

Can you turn or disable the power button of the Samsung S4?

My phones power button has been screwed up somehow. When I lock it, it locks but turns off 5 seconds after, and when I turn it on it lights up but goes off again. Its almost as if the power button is stuck in but its not though. I managed to get it on and download a soft screen lock for now, but any ideas on disabling the lock button
