Battery discharging fast when the jack & hold connector is connected

Ive replaced my Ipod’s battery with a new one (https://pt.aliexpress.com/item/400016690...) but the ipod isnt holding the change for too much. I did many tests and noticed that it only discharge fast when the jack and hold are connected on the mortherboard (even its not playing a song).

Already bought a new jack & hold and im waiting for it, but would like to know if someone else already had the same problem, if not, lets wait till I get it to make a new try, if yes, please, comment what you did to solve this problem.

Thx
