Not charging after screen replacement
So i replaced the screen on an iphone 6s, the phone was brought to me almost dead just flashing battery, put it on charger and it charged to 35 percent. So i proceeded with the repair, so its safe to say the battery would charge before i replaced the screen. Installed new screen, turns on everything fine. But when plugged into charger it shows charging but its not charging the battery. I have ordered a new battery for it to see if that will fix the issue. I have tried a reset by holding down the home button and power button. I know i fully discharged the power aswell before removing the screen. I always hold down the power button before removing screens. Any idea how or what could cause this?
