What should I expect to see testing the battery with a meter?
I slipped and fell today with my iphone in my back pocket. the screen doesn't appear broken, but the phone does absolutely nothing, except hold down receipts on my desk if I ask it to. I dismantled the whole thing looking for loose connectors, a crack in a board, but the only thing I see suspicious is the battery appears to be a little floppy on one corner, like a cake of plaster with a cracked edge. The battery has four pins, and when laid out in front of me with the pins to the lower left edge looking down on it, pin 1-2 equals zero, 1-3 =2.5vdc, and 1-4 = 3.7vdc. Pins 2-3 and 2-4 are the same as pin 1. Is this correct? I'm concerned about the 2.5vdc reading, and can't find a pinout anywhere on the internet. weird.
Is this a good question?
