iPhone4 bettery connector soldering
As you can see, the first image below is the batterty connector on the iphone motherboard.(Yo
the second image is the actual battery connector that you plug in iphone bettery to this connector.
the third image is what it looks like when the connector is attached to the motherboard.
My question is, I don't know anything about soldering. I only know how to solder. so can I just solder those 4 pins and would I able to use the bettery normally again.
You need to reSolder the good pins and Crete a jumper from the connector to the gold tabs Just in front of the two that are missing. The one on the right can be grounded to th metal cage around circuit board if it is bad. The left is the hot side and it is a little more difficult to repair.
