IMHO after 50 years of being involved with electronics, the lightning port is not a really good design in the service for which it is intended.[br]
- picking up fluff/grit and hiding it (yes I have had this)[br]
- very little tension on the eight very small contacts[br]
-quite large forces can be applied to the contacts in the charging port by the connector being pushed up & down or from side to side, damaging the innards of the port.[br]
-leads are replaced by after market leads which may not meet the mechanical requirements causing insufficient contact tension ( some after market leads that I have had, have little or no gold plating)[br]
[br]
All this will lead to non charging and or the “may not be supported” message.[br]
Solutions.[br]
Do NOT buy the cheapest replacement leads. They will fail early & give you nothing but trouble.[br]
Do NOT put pressure on the leads. Preferably do NOT use the phone when you are charging it.[br]
See if some enterprising manufacturer in China will come up with a after marked rubber bung that blocks the charging port when not in use.[br]
If a new, good brand replacement still gives you a problem, change the charging port (easy & not expensive if you do it yourself).[br]
