Why does it take a few seconds for my iPhone 17 Pro Max to turn off?

Hi there, I’m here to ask a question on why it takes multiple seconds for me to turn off my phone when it didn’t have this problem before.

Whenever I hit the button just to make my phone off (not shut down) it takes a few extra seconds for it to be off.

I’m on iOS 26.3.1 but I had this problem before I updated my phone and I thought it would’ve went away by itself if I just left it alone.

It’s been a few days since this has been happening and I’d like to know if I can get any help for this.

(I was gonna put this in the Apple subreddit but it said my post might get taken down 🥀)
