IPhone 6s+ stuck in infinite loop screen

I was playing on the computer today when I went to the toilet. After I came back, I saw a loading circle on my screen. I thought its just a update but that wouldnt make sense because I didnt click anything. Then I thought I can just wait some minutes but now its already 4 hours. Ive been looking for solutions but I got a specific problem!

I cant press the Home and Power Button at the same time since my Home Button is broken. And I cant find any solution how I can restart my phone otherwise.

I tried everything but I just cant restart it.

Solution 1:

After 4 hours of waiting, the battery was finally empty. Then I was able to normally start the phone! :)
