After I replaced my charging port, it turns on but doesn't charge

My iPhone 5s recently didn't want to charge so i decided to change the charging port, I carefully followed each and every step to replace the port and followed the guide on ifixit.com. After completion I came upon a error, I plugged in the device with a new charger and then the device turned on like normal, however, once the devices lock screen appeared the lightning bolt next to the battery didn't appear, IT WASN'T CHARGING. I don't know what could have happened or what I should do to fix this.
