Why are some functions of my phone not working?

I recently replaced my old phone's battery with a new one and after powering on the device, some functions stopped working such as both rear and front cameras, both speakers, the flashlight, and vibrations and haptics. I tried to calibrate the battery by following the instructions included in the new battery but nothing changed. I changed back to the old battery to see if anything would happen and all of said functions worked again meaning that none of those parts were damaged during the installation process. But switching to the new one causes them to not work anymore. Am I doing something wrong?
