I wonder why, I mean, it's a battery after all. They've pulled off probably a hundred other phone designs and they aren't new to the market. What's particularly wrong with the Note 7 that they can't fix in a PCB or battery redesign?

By now I would say the image of the Note 7 (and the replacements) being associated with exploding batteries. It might be best to ditch the Note 7 and move on to a newly named phone.

Samsung has been dragging their feet on this. Their response has lacked clarity and urgency.

Paradoxially this kind of tepid circumspect response designed to first protect the brand has a far greater chance of damaging the brand permanently than coming clean unequivocally and proactively taking full responsiblity.

The second approach you take a loss but live to fight another day, the first the public begin to harbour doubts about your commitment to safety and your users and that can cast a long shadow on your future products.

I don't think they were trying to protect the brand, they were trying to protect their bank balance by avoiding recalling, replacing and ultimately scrapping the product line.

They are probably going to kill the name and wrap fixed internals in new box with new name.

This is certainly not the first such case and it's unlikely to be the last. I recall Sony having numerous recalls related to similar issues. It's the nature of dense energy storage media to run into problems if the energy is allowed to be released too quickly, but the characteristics of Li-ion do make it more conducive to cause these type of incidents. Battery university has a nice explanation of the typical causes h…

>if the energy is allowed to be released too quickly Wasn't this the problem? That the kernel was drawing too much voltage from the battery, or something like that I read.

I'm no electronics engineer, but I don't think "drawing too much voltage" is a thing.

As current goes up, resistance has to go down, so there will be a voltage drop across the battery terminals.

That's my understanding, someone correct me if I'm wrong, or otherwise help clear this up?

There was a theory that they charge the battery to a too high voltage, creating internal shorts.

Hopefully now people will realize that every battery powered laptop and phone on an airplane is a potential bomb.

It will be interesting if any major air carriers decide to ban the brand from flight.

with regards to your comment the industry should strive to show otherwise and there should not be any reason to not be able to predict this type of failure occurring at the device level. there certainly have to be some telltale signs that are detectable
