Why won't my iPhone Charge?

A 32GB iPhone 4, GSM, AT&T

I did a screen replacement, along with the whole dock connector assembly (including speaker assembly). I also purchased a new, OEM battery from Canada (punctured the old one by accident.)

I pulled out the battery connector by accident when prying out the battery. I superglued it back in. The phone would not work without being plugged in. After fiddling with the connector a little, the phone started working off the battery again.

Now, the only problem is that the phone does not charge (tried both Mac & wall). It has been using battery (is at 32% right now), but will not charge. When plugging it in, the sound comes, and the bolt on the battery appears.

iTunes also says there is a problem with the iPhone, and recommends that I restore it. I want to avoid doing this as I will lose the unlock.

I thought the issue might be the battery connector, but since it is now able to run off the battery, that shouldn't be the issue, right? I don't have a soldering iron.

Answer this question I have this problem too

Is this a good question?

Honestly I think it is the battery connector on the logic board, that and you could have installed the dock connector assembly incorrectly, or it was defective.

But most likely it's the battery connector.

I tried 3 different dock connectors after reading your reply, the issue remained so I doubt it's those.

I don't even know where to start with the battery connector though. What are my options to fix this? I'm a little confused, the iPhone is running off the battery fine, it just isn't charging, is that necessarily an issue with the dock connector? Do you think it might be a bad battery?

I agree with Josh, bad battery connection, bad battery, or worse case scenario if you had a loose battery connection it could arc and hit a resistor/etc, on the logic board and fry it -- in this case, double check with a good magnifier and look at the board for any signs for "burnt" components.

^ first, try another charging cable. I've seen cables that will power up a device, but the device won't charge.

Oh no. I'll check both the logic board and the dock connector assembly.
