iPhone 1st Generation: Can you replace the battery without soldering?

Thu, 17 Dec 2009 20:31:28 -0700

Is there room in the iPhone to simply cut the old wires, strip the end, and then attach the leads to the replacement battery wires? (of course using some heat shrink tubing to insulate the connections.) It shouldn't take up that much extra space, if you judge the lengths correctly. Judging by the photos here, I think there should be enough room.

I read so much about the difficulties of desoldering and soldering on the iPhone board, thought this might be a safer route. Of course, you still need to be careful not to cause a short, etc.

iPhone 1st Generation: What to look out for when soldering the battery wires

Sat, 15 May 2010 15:35:08 -0700

I've got a iPhone 1st Gen that I'm trying to get the battery changed.

After desoldering the old battery out and soldering the new battery in, the phone wouldn't charge.

When I plug the charging cable in, the apple logo shows for a bit, then disappears. And that's all it'll do.

I know I've got the black cable correctly soldered as there is contact between it and the big metal cover above it.

How do I go about testing the red and white cable if they are soldered in correctly?

iPhone 1st Generation: Battery's tin-solder connects with communications board's cover plate

Tue, 01 Feb 2011 08:37:29 -0700

I successfully fixed a broken solder bead of the black cable connecting the battery to the communications board. But due to a very raw, non-precise soldering iron, the tin-solder also touches the silvery metal plate that covers the communications board.

Any problem with that? It is working fine now for one day already.

Thanks in advance!
