I have a feeling there's something wrong with my female socket (on my phone). When I try to insert my connector it just feels a bit loose and if it moves my lead falls straight out. It's really awkward when in the car after a drive I think we're charged up and ready to go, instead it's flat and wants to turn off. I'm not sure if it's filled up with fluff so I try pushing it in harder, wiggling it around and it gets going... but any interruption or nudge and it falls out again, sometimes I don't notice. Now I do it at work on the desk, no one else seems to mind.
