Charging lead pops out - "makes and breaks"

By lead are you referring to the Lightning cable end? If it does not fully seat into the charging port then there is some type of obstruction in the actual charging port. Often times lint, dust, debris, dirt, etc from our daily use, our clothing can get stuck in the charger-port.

I would gently insert a paperclip or if you have fine tipped tweezers gently remove the items. Be careful there are vital pins in the socket that if damaged will not operate properly when you charge again.
