Re: Pushing the envelope too hard

It's also likely that there are similar records that show the pressure placed on the battery manufacturers to work even further down below the price agreed as part of the contract bidding process.
That is exactly how it looks to me, and I've seen this situation oh too many, so many times.
From the article: Collectively, the three found that the two battery-makers who supplied kit to the Note 7 did a lousy job. Manufacturing defects such as bent electrodes that touched, absent insulating tape, too-dense designs, bad welds and easily-breakable internals created ideal conditions for a short-circuit and runaway failures.
Unlikely, as if this was true, Samsung's supplier QC checks would have found these issues years ago. In addition, "manufacturing defects" that are identical between two suppliers are highly unlikely, as one reason why you have a 2nd source manufacturer is to minimize manufacturing defects. More likely it is a DESIGN defect, right?
In the interest of disclosure, I am somewhat closer to this situation than most. So here it is: as Reg already reported, the battery was fine except for plates that were too long and would overhang too near the edge of the package. The real issues is, as Reg already reported, that Samsung did not follow standard battery safety practices, and left no room for battery expansion.
Representatives of three firms also concluded that the Note 7's own electronics did not cause the batteries to misbehave and indeed contained fail-safes that exceeded industry best practice.
Incorrect from my perspective. IMO Samsung's battery electronics was completely off-the-shelf industry standard. IMO they did not want to pay for any more for the electronics than they needed.
