It has been four months and this hasn't been a problem so far. It seems to toggle between charge/discharge quickly with slight movement though. I hope that is just normal behaviour and not a symptom.

I really wish that this doesn't become an issue because apparently the warranty is not extended to Canadian residents

The poll gives me a positive vibe but those that suffered, can you please tell me how many charges until the port stopped working and what were the symptoms?

Thanks.
