You most likely have a poor quality replacement battery. You will need to get a good quality replacement battery from a reputable supplier. iFixit sells good batteries but they may not ship to your location.

Hi,

You either have a faulty battery, or you've damaged the tristar chip in the phone from using cheap cables.

If that is the case, you'll have to get someone who can micro solder a new tristar chip on. :-)

Is the phone able to be switched on when you turn the phone off and plug into charger after?

If not then U2 Tristar Charging IC is definitely bad.

If the battery doesn't show any signs of charging once it goes flat, same as above.

Do note that a bad or clogged up charging port can cause phone not to charge completely.
