Replaced Battery with iFixit battery and now the phone constantly reboots every few minutes. I put the original battery back in and the rebooting stopped. I bought the new battery due to the original doesn’t hold its charge very long. I had no other issues. Replacement was simple with no problems. Any ideas why it reboots with the new battery?

Install the old battery and see does it still crash if not then sounds like a defective battery
