RC already，but also can't connect my iphone x

Use the cable that came with the Iphone, and plug it into the bottom of the RC. Remove any plugs that are in the side port of the RC completely.

Is the RC connected to the drone? If not, the phone will never connect.

Use your 6S. This way you won't have to use your iPhone X battery to do drone stuff and you can do other fun stuff instead. Win-Win scenario.

If you have a virus on your old iPhone or other software issues, plug it in to your computer and do an iTunes restore. If it is a hardware issue, I have no more advice. I am using an iPhone 7 and everything works flawlessly.

There are no known iOS viruses.

That must be one of the "advantages" of Android devices. Open platform for anyone to do what ever they want. And no closed doors, and nobody knows for sure how many doors there are.
