How to lock an iphone with a broken power button WITHOUT AssistiveTouch?

[OrionMaster]

My iPhone 4s (iOS 9.3.5) has a broken power button. While some people say using assitive touch can get around that I find it extremely annoying that thing stuck on the screen all the time. I just want a little app or button that shuts off the screen
How to do that?

Pretty sure no 3rd party app is going to let you do it. The fastest answer is Assistive Touch. I had to do the same on an old iPhone 4.

No app will be able to do that for ya. The only way is getting that button fixed or using Assistive Touch.

If I were in your situation, I would probably just set the phone to lock automatically after 30 seconds.
