Every 3 minutes my iPhone SE restarts

Hello. I just got a iPhone SE with everything original except display was touch irresponding on left side. So i just replaced the display with a new one and replaced housing bcs it was in very bad condition. Everything was fine. Max battery capacity was like 87%. I fixed it, tested it and everything was working perfectly. After like 2 days i turned on the iPhone and for me i knew something went wrong at this time. The battery stopped charging already. 3uTools showed me “no data” on battery and every 3 minutes just started rebooting it self. If i go to settings, battery and battery health i only see here is unlimited loading. So i just buyed a new battery and test it out and nope. Still the same problems. I cant find any fix to this problem so i asking u guys for a help. Thx a lot.
