dialogue: Amanda: oh no, my phone charger has stopped working
  Keith: the cable or the charger itself?
  Amanda: dunno, it just won't charge
  Keith: can't you ask your sister to lend you hers?
  Amanda: but I have an iphone and she has a samsung
  Keith: hmm, yeah, but the charger itself should be the same. so if you use your cable with her charger, you could see if it works?
  Keith: then at least you'll know which part needs replacing
  Amanda: oh, I could do that, yeah
  Amanda: should I get the spare part from apple or...?
  Keith: idk, I've never had an iphone. I hear not all cables are compatible for some reason but imo you should be able to find a cheaper replacement that should work... their prices are too high
  Amanda: uhh... alright, I guess checking what's wrong comes first
  Keith: can you do it now?
  Amanda: yeah, I'll brb
  Keith: k
  Amanda: back
  Amanda: and it's still not charging :(
  Keith: then it must be the cable. or...
  Amanda: or?? there's another possibility?
  Keith: well, I guess there might be sth wrong with the charging port but that's the worst case scenario
  Keith: so let's not think about it yet?
  Amanda: I'm a bit worried now but ok :(
  Keith: I've found some shop that sells replacement cables
  Keith: <file_other>
  Keith: I'd try this one first, see if the phone detects the cable at all
  Keith: cuz if it does, then problem solved, if it doesn't... then it might be the port
  Keith: but it's cheap enough to give it a try
  Amanda: thanks, I'll do that... I hope it'll work, not sure if I can afford a repair :/
summary: Amanda's iPhone is no longer charging. She tried with her sister's charger, but it didn't help. It might be the cable or the charging port. She'll get a cheap replacement cable to check it.
