回答“iPad doesn't charge after battery drain”With these details we can't exactly help or at least describe but if you go to Apple they replace the charger and inspect the product its self. I was thinking that if it has some sort of overlapping ridge on the charger that is it problem and you must go to Apple for that or else your iPad will become bro land you won't be able to access it. I'm sorry that this is probably not the answer you were hoping for but this is the closest I can get with these details.

回答“How do I get my music to play through my earphones?”It simply is just bent it was bent so long so unless you straighten up the wires it will not work. I advise you to get a new headphones. That is the only solution.
