iPhone 3G: 3GS-battery in a 3G - never opened before.

Wed, 23 Feb 2011 17:58:38 -0700

I opened an iPhone 3G to check what was wrong with it. It was regularely turning itself off, even when fully charged.

When I opened it, the "Do Not Remove"-sticker was intact. I removed it, together with the mainboard, to see this:

"616-0347" - which is a 3GS battery. Inside a 3G iPhone? Which supposedly has never been opened before? What is the deal here?

I have now changed the battery to a 3G one ("616-0366"), and hope the problem is solved.

iPod Touch 3rd Generation: Why were the volts of the second battery decreased?

Thu, 17 Mar 2011 01:30:34 -0700

One day, I realized that my iPod Touch wouldn't turn on, so I opened it and I diagnosed that the volts of the battery weren't 3.7 (as they had to be), but 2.1! So I replaced that battery with a new one, and my iPod worked successfully. But after three days, it stoped working again! Then I checked again the battery and the volts were 3.04! Could anyone help me, please?

iPod Touch 3rd Generation: Can a battery which has been short-circuited, to work again?

Tue, 08 Mar 2011 03:26:26 -0700

My battery had been short-circuited and my iPod Touch wouldn't turn on, but after 10 days, I charged it again, and it turned on! Then I unplagged it from the ac adapter, and started using it. When I realized that the battery was running out of charging, I pluged it again on the ac adapter, but nothing happened, it wouldn't be charged. So I replaced the old battery with a new one which worked only for 3 days and then it broke down without any reason. But after 2 days, I desoldered and then soldered the second battery (again) and my iPod turned on, but after 10 minutes it stopped working completely. Could anyone help me, please?

iPhone 3G: Phone dies on new full battery after few seconds

Sun, 05 Jun 2011 21:16:30 -0700

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

iPhone 3G: iPhone 3G will not sync or charge after battery replacement

Thu, 11 Aug 2011 20:37:24 -0700

I recently noticed that my iPhone 3G's battery was running down stupidly fast so i decided to replace it. I checked that everything worked (which it did) other than my mac will not recognise it and it will not charge.

After looking around i found that it could be to do with the SMD element, but from what i can see it looks intact. I also think that the dock connector is working because whenever i plug it in when the phone is off, it turns itself on but will not say it is charging.

Any help would be much appreciated,

Thanks
