I can't turn on my iPhone !!!

Hi

It's been 1 hour now , that I'm trying to turn on my iPhone 5s. It's off , and when I turn it on , it's on the apple logo , and goes off after 1 minute. I tried some tricks I found like clicking both home button and the on/off button ... or the volume buttons.. NONE WORKS ! AND I'M SO AFRAID THAT I MUST RESTORE IT ! IT'S THE WORST THING THAT I REALLY DONT WANT TO HAPPEN. So logging on iTunes won't help , because I had bad experiences where I did it and had to restore my iPhone.. and all was gone. And I usally don't save my things. Any one will be enough nice to help me please ?

Thank you 😟
