Aggressive design caused Galaxy Note 7 battery explosions
By Thom Holwerda on 2016-12-06 21:03:03

What's interesting is that there is evidence in the design of an intellectual tension between safety and pushing the boundaries. Samsung engineers designed out all of the margin in the thickness of the battery, which is the direction where you get the most capacity gain for each unit of volume. But, the battery also sits within a CNC-machined pocket - a costly choice likely made to protect it from being poked by other internal components. Looking at the design, Samsung engineers were clearly trying to balance the risk of a super-aggressive manufacturing process to maximize capacity, while attempting to protect it internally.

Fascinating look - with photos - at the (possible) cause of the Galaxy Note 7 fires.
