Chosen Solution

My iPhone 7 Plus, which I have no problem, aside from the charging port. The charger works fine, but once I accidentally move the phone, it stops charging and I have to move it again, and carefully place it back on a table. I tried cleaning the port, it worked, and for a few days I had no trouble charging. Now, it’s back, and I wonder what could be the problem? Could it be there’s just dirt again?

Does the charging cable leave no gap when plugging into the charging port? If there is still quite a noticeable gap the port needs to be cleaned more.
