Replaced Battery and new battery doesnt charge

I just got my replacement battery yesterday and everything seemed to be great, Battery was at ~78% then I set it aside until I went to bed.

In the morning I got my phone off the charger and noticed that it was at 70%, I just assumed that I didnt plug it in all the way.

I got in my car and tried the charger and i heard it make the connection chime, but it wasnt charging. I tried again when I goto work at my desk the way I have since I got the phone and still it would light up with the battery lock screen, make the chime, computer wanting to know if I want to transfer photos. But I look at the battery icon in the top and it is green with a power plug instead of a lightning bolt.

I've tried taking it apart again and rebuilding it, just incase a connection wasnt made, I've tried multiple usb cables/ports and even the wall adapters we sell here. All the same.

Battery is slowly dropping, now at 59%, uncertain of what I should try next.

Suggestions?

Not providing this as an answer as it isn't one, it's just something to check: sounds like the current sense/feedback pin from the battery might not be making contact as the same behaviour was observed in my iPod when I fitted a new battery with solder terminals, and the feedback tab didn't solder to the board. Check to ensure the battery connector is sat properly on the board and that all pins are making good contact. Otherwise, perhaps the battery is faulty and there's no feedback from it.

Another "me too". I replaced the battery in my iPhone with a kit obtained from iFixit. It showed 78% capacity when i first powered it on, and it's steadily been decreasing. The charge icon shows in the battery display and the phone makes the "charger attached" noise, but no charging happens.

I am in the same boat really. My iPhone stopped charging after the first time I used a brand new iPhone 3GS compatible car charger. I ordered a new dock connector and battery.

After installing the replacement battery I was happy to see the phone boot up, but when plugged in even it the screen showed the charging symbol and made the chime, the battery would not charge. I have made sure that all connectiuons are made. The phone is now dead again.

No idea what I can do next.

if you believe you have a bad battery then you need to return it to source.

there are many stories of OEM/non apple parts causing these issues. You can buy apple parts/seconds.. they cost a bit more but are worth it.

Rev- I would also go through the checking connections/cleaning contacts as any time you open the phone for repair there is a chance of damaging parts.

The other part that is responsible for charge is the dock connector-give it a *!$* good clean and check for dirt and debris in the dock
