My iphone turned off and had a charge of 36%. I tried to charge it but it still won't turn on. What I do? It is an iphone 8 product. Somebody please help me.

I really don´t know. Okay I´ll explain you the whole situation. When I slept I saw that my phone had a charge of 36% and then when I woke up my iphone wasn´t turning on. I tried to charge it but no results. Usually when you charge the iphone it will show a red bar but when I tried nothing showed up on the screen. My iphone has not even fallen nor has got wet. The phone was all fine until this morning. So I searched up and one solution that showed was to press the home button and the block button at the same time but when I tried to press the home button I couldn´t do it. The home button was really hard to press.
