my battery is draining fast after using unauthorized charger

What can be the problem if my battery is draining far after using unauthorized charger? I have tried to change battery which didn't help at all.
The iPhone is able to charge but after hour and a half the battery is dead.

thanks!

Re: my battery is draining fast after using unauthorized charger

likely the unauthorized charger has caused an issue with the port... those can be replaced by qualified service personnel...

Thanks for the answer.
Does apple one year warranty covers that problem in the port?
