Polarity of the Battery contacts?
I have an iPhone 4 here, that does not charge anymore through USB (neither is it recognized in iTunes, tried diff. Macs, PCs, cables).
While narrowing down the problem, the battery went empty.
I took the battery out of the iPhone in order to (re-)charge it.
Therefore I want to ask, which of the 4 connectors of the battery are used for charging and to which pins the positive and to which the negative current goes.
Thanks for your help!
