All the potential energy in a cell phone is stored in the battery; the battery is what was defective. Not the phone.

Well, I guess I can't really say that with certainty. I suppose it's possible that a defect in the phone short circuited the battery and made it overheat and explode or something along those lines.

heh.

A small short circuit is enough to set off a battery of that size? The power in those batteries isn't all that much. Even if the battery dumped all of it's liquid contents and there was a spark, I highly doubt that would have caused anything more than a burn on the skin from the leaked liquids over time. What was she doing? Sticking her ass in the oven or something? where'd all that heat come from?

Li Poly batteries can put out considerable amounts of current when shorted. Shorting these cells is a very bad thing. Internal heat produced puts them in runaway condition. When this occurs, the cell may rupture under considerable pressure spewing toxic materials and flaming alkali metal! She got off lucky. Also one should never attempt to extinguish such a fire - which could be considered class D in the case with a notebook battery pack! - with water.

There are many safeguards to prevent destabilisation of secondary Li-Ion power sources in portable consumer electronic devices. Unfortunately, there exists no system of redundancy on said safeguards due to cost.

Cheers!

hmm i've heard of something like this before

Good, maybe this will teach her that cell phones are stupid and she shouldn't be on it for half of her life.

same thing happens with any brand. non factory batteries don't have short/overload protection.

Yup.

See shuttleteam's post. He explained it much better than I could. It's all about the duration of the energy discharge. 😉

Short = boom!

It's dangerous to short circuit any battery for this reason, really.

Might I suggest that, since you are a guy, you do not put it in your front pocket...
