The trick is to insert the cable in the phone first, no power, THEN

How does this make it not loose over time?

If it "gets loose over time" it is not the male end that comes with a
new cable, it is the phone end's grounding shroud.

The connection failure is due to loss of the Gold plating and the
carbonization of the contacts.
