To much dirt in charging port

Yes and yes.

Make an appointment at the Apple Genius Bar for service. If you need to find an Apple Store - Find a Store - Apple. Also, see How to find your nearest Apple Authorized Service Provider (AASP) or Distributor (AAD).

Hi iPhonechargingc,

I am not sure 🤔 if you can get your charging port cleaned out at the Apple Store or not, but you definitely can contact your local Apple Store in that case. But I would recommend you to only get it cleaned at an Apple Store and not some unknown place that fixes phones.

Always ready to help,
