See those two batteries in the image above? They were both taken from Apple’s iPhone 3GS. The one on the right ballooned within the device, causing it to literally burst at the seams, breaking the device’s plastic shell, pulling apart its metal bezel, and even popping its screws. Could this happen to your iPhone, too?
We are getting quite a few phones in that look like that have been ripped at the seems. When we open them up the battery has ballooned massively. The force is strong enough to break plastic, bend metal, and pop screws.
It appears that there is no obvious cause for the issue; iPatch reports that none of the devices they have repaired were subjected to extremes of temperature, fluids, or abnormal forces.
Have you experienced anything like this with your iPhone 3GS?
