New battery for 4s from ifixit-still draining fast

I replaced my battery with one from iFixit, but it still drains fast and will get hot. It will drain overnight every time if not plugged. It also turns off by itself and I have to do a hard restart. When it does restart the battery will say it is at 30%--not at 2%.

I have turned off all background apps and even turned off the Mail function (and retrieving mail through Gmail app)

Thoughts? I want to give this to my daughter to use and will get a new phone for myself

If something is getting hot, it usually means there is damage or a short on the logic board, you would need to inspect the board to see where the damage is.

It could be from a heavy drop, liquid damage, you may have damaged it yourself when inside the phone, or could be cheap cable damage.

Or in the rare case, it could be a faulty battery again. :-)
