  1. I have a battery but the connector that connects it to the iphone broke off i took apart the battery a few months later to fix it, just to find out htat the battery is dead.. I got to the four silver squares on the battery do you know which ones are which?


    • Depends on which generation of iPhone you’re talking about. For the iPhone 4, starting from the outer edge of the protection PCB, it’s PACK-, HDQ, NTC thermistor (10k), PACK+.
