So how about that Samsung Galaxy Note 7? The would-be Korean competitor to Apple’s iPhone 7 ended up being a literal flaming disaster. It’s a shame for several reasons, not the least of which that it seemed like a real nice phone. Samsung has completed its in-depth investigation and come to the conclusion that both the original battery and the model given out as a replacement in the first recall had completely separate defects that caused them to be prone to short-circuiting. The company held a press event in Korea early this morning to talk about what happened, and why it hopefully won’t happen again.
Samsung found that the original battery suffered from an internal deflection of the negative electrode in the upper-right corner. For the second model, the company discovered that a welding burr on the positive electrode eventually broke the layers separating it from the negative electrode.
