The batteries expanded upon use, and due to the slimness of the phone, they had no room. This caused the conductive chemical layers within the batteries to leak through the porous separating layers, and the resulting reaction caused fires. To me, that has to do with slimness.

So two independent companies (after testing many phones) came to conclusion that there were two different manufacturing defects in batteries used. But they were wrong and the problem was phones thinness. You should contact Samsung immediately.

yeah right, like laptops need to be designed with "extra space for the batteries to grow". it's not a slimness issue

I don't believe you are correct. No device manufacturer has room available when it comes to internals. They don't leave gaps that aren't physically required for operation. This isn't like an air-cooled desktop PC, it's a device that has no affordances for excess space. The big problem with the Note 7 was the battery design and manufacture. Nothing within the device itself was the problem. These batteries would have exploded in any device they were placed in (though they were built specifically for the Note 7, like any phone battery nowadays): https://news.samsung.com/global/infographic-galaxy-note7-what-we-discovered https://news.samsung.com/global/infographic-galaxy-note7-wha...

  > (though they were built specifically for the Note 7, like any phone battery nowadays) Samsung requested a battery with the design of the phone in mind. That design was faulty. Under normal operation the electrodes would expand and due to the design of the electrodes and the faulty separators, there was a fire. The slimness/design of the phone necessitated a battery design which was faulty. I'm not saying that the battery literally had no extra room. There was no extra room without causing a short circuit and fire.
