Thread: new battery won't grab a charge
04-15-2011, 05:06 PM #1new battery won't grab a charge
Well my old 3gs battery was on its last leg it would decide to randomly cut power.
So I purchased a new one.
I put it in, closed it up, and everything worked fine. Booted up to 43% battery. I plugged it in to charge and while it was charging I noticed the percentage was decreasing. I thought it was just a bug so I didn't pay much attention to it.
I left it charging over night and when i woke up it was at 9%. So out of curiosity i used it until the battery died.
Now the phone boots up to the "out of power screen" When I plug it in it registers that it is charging but it just won't.
What do you guys believe to the problem?
Is there a ribbon cable that i could have damaged that would cause this? Or is the battery just not properly alined.

3gs have serious battery issues. You need to get an OEM or better iPhone 3gs battery. The problem is that the battery circuitry is not compatible with your 3gs. If you are very sophisticated you can desolder the old circuit board from your old battery and solder to your new one. Or just get a real 3gs battery that is compatible with your 3gs. Check the APN # on your old battery and get the same APN # on your new battery. (Apple Part Number) Good luck. Brad

Thank you so much for the reply, However, not even my old battery is being charged anymore.
I also replaced the power button, wifi, vibrator, and antenna if that makes a difference.
Would you be able to tell me how likely it is that this is a main board issue? I'm shitting bricks thinking that it might be . I don't recall ever putting it through large amounts of stress.

can determine the difference between 3g and 3gs batters by the APN number as mentioned..
In the past it did not matter what battery you used, but since 4.0 iOS has been a lot more picky about batteries

The new one is a 616-0435; the old one is 616-0434. However, neither one of them take a charge now.
I've read quite a bit about cleaning the motherboard with alcohol do you think this will help it? I've noticed a reasonable amount of residue where the battery connects + my phone was very dirty upon opening it for the first time.
