iPhone 4 CDMA not turning on without being plugged into charger.
I have an iPhone 4 CDMA Verizon that had a a broken digitizer but LCD was working. I purchased a replacement digitizer and LCD and replaced the screen with no issues. BTW, I have replaced 20+ iPhone 4 and 4S screens with no issues.
When I went to turn on the phone it wouldn't turn on. I double checked the battery connector and everything was correct. I then plugged in the phone to a wall charger and the phone booted up. I unplugged the charger and the phone turned off.
I suspected the battery could have been bad but the phone wasn't experiencing these issues before screen replacement. I swapped another known good battery in and the phone is experiencing the same issues.
I have disassembled the phone and double checked everything and still have the same issue. I read that it could have been a battery pad port that was damaged but I was unable to see any damage.
Anyone have any tips or suggestions?
Thanks

those battery contacts are pretty easy to loosen when you lift the battery out..I'd take a good look at them where they connect onto the board. I've had one or 2 cause a problem like this.
