iphone 14pro not connecting with the charging cable

Have you tried inspecting and cleaning the lightning port on the bottom of the phone?

Are you using a high quality cable, either Apple or from a reputable manufacturer, and certified as Made for iPhone?

I have been plugging in and charging iPhones and iPads for 15 years, and so has my wife; neither of us has ever had a problem, so most likely it is an issue with your phone or the way you are using it, not something that Apple can magically sort out by waving a magic wand.

If you have a recurring problem with dust or cruft in the charging port you should consider changing however it is you are carrying the phone. My wife’s phone is 4 years old and has none (I passed it on 2 her 2 years ago). She had an iPhone 8 previously for 5 years and it had none. She kept each in a case in her purse. My 14 Pro is a year and a half old, and has none. I carry it in a belt holster. If you carry it loose in a pocket it should be in at least a soft slipcase. You have a $1,200 piece of delicate electronics, and should treat it with respect.

If you used a new cable and it only mildly helped. Then I would recommend a Genius Bar appointment to have the phone hardware checked to see if there is a problem with the charging port itself.
