Phone dies on new full battery after few seconds

Hi

I just replaced the battery on my iphone 3g with a 1600mah version. Upon restarting, everything is fine, but the phone shuts off after only a few seconds of use, even when showing full battery. I have charged it for about 16 hours, it shows full charge but still shuts down after about 10 seconds of a phone call. It gives a short rotating white ring, then dies and cannot be restarted (does not show flashing battery logo). When I connect the adaptor, it restarts with white apple logo and is fine (although a couple of times it needed a reset of date and time). Each time it has restarted, it shows full battery.

But ...

It doesn't do this when connected to the power adaptor.

Everything else seems fine - docks ok.

Have I installed a dud battery, or does it need some kind of shock to wake it up?

Hope someone can help me.

Regards

SimonC

I think you are right. I am ordering a new one, so hopefully that will sort things out. I am not too happy to take the phone apart to put the old battery in again. Those connectors are beasts for my clumsy fingers, so I will wait for a new battery and hope that it is a good one.

Thanks for your reply. I had guessed it was a bad battery, but just wondered if I had forgotten do so something and needed to get a second opinion.

It sounds like a bad battery to me. Put the old one in to see if it does the same or go back to normal. If it doesnt, then its the new battery. Return it and order from another place, or try and get a replacement.
