N's phone's charging port is fucked, I gave it a go with a baby toothbrush that I had spare (I bought some a while back for the cats and now have 1 cat left and he only has 2 teeth, so I had some baby toothbrushes still in their packaging) and it's still not doing a fast charge.
I think it's because he works in an environment with a lot of flour and icing sugar and it gets into the port - the usb-c cable won't even go all the way in, I think there's just a load of caked up gunk in there (that probably tastes of sugar and raspberry jam).
