My phone is stuck on the iPhone logo.

So my IPhone 5S died, and I plugged it in, instead of showing the dead icon, it went straight to the Apple icon but it's been like last for like 24 hours. It won't even turn off. I've tried a soft restart, a hard restart, letting it charge, using different chargers, plugging it into the computer, and I let it sit overnight without messing with it. We looked up what to do on google and tried just about every idea we found, but nothings working.
