Cheap screen is blacking out, and drawing more power from the phone than what it is supposed to, causing the top of the board to warm up and the battery to drain faster than before. On top of that, you may have a cheap battery too, as those are a dime a dozen. Don't cheap out on screens, you end up paying more once you factor in the time wasted repeating the repair, getting aggravated, and possibly ending up with a buggy screen if the seller does not warranty it or just uses cheap screens and would be replacing it by an equally bad part. And/or you may have a partial short on the top of the board, causing the backlight to act out and the board to warm up. This may be due to unplugging the screen without disconnecting the battery and/or by coincidence. It is not very likely, but if it did happen, this partial short usually leads to a full backlight failure. If I were you, I'd cut on the losses and just purchase a good quality screen from a reputable seller such as fixit.com to install yourself. Or find a goo repair tech and request an original-like quality screen. Expect to pay around a $100 no less.
