Defective battery according to CNet: https://www.cnet.com/news/why-is-samsung-galaxy-note-7-explo...

Even replacement phones caught fire, they blamed the batteries.

Even this article is inconclusive... There has been no definitive cause.

My initial presumption was shoddy batteries+ quick charge 3.0 extra fast charging + hot Qualcomm 820 just to add.

It was first Samsung phone to use quick charge 3.0. If there was a battery defect, rapid charging didn't help.

This is what I'm wondering. Did they fail to adequately test the quick charge feature or do they have a supply chain issue? The Nokia phone explosions were caused by Nokia accidentally buying counterfeit batteries because they sold more units that they had anticipated. A startup I worked for back then was created to solve that particular problem (Verical).

No sh&t, battery? Who would have thought? I assumed it was CPU heated to sillicon's ignition temperature.
