The battery connector is pretty bendy, so unless you folder it, it shouldn’t be an issue. You might want to ensure the connection is good. What I like to do is take my thumb, and rock it gently in, then press moderately on it. You should hear a small snap. Don’t push too hard though. Also ensure all connections are properly being made, including the LCD, Speaker, and digitizer. Check for any obstructions in the port as well.
