Samsung Galaxy Note7 exploding battery likely caused by extreme internal margins

05 December 2016
Samsung was too aggressive in its internal design margins, leaving no room for the phone's safe battery operation.

Did they solidly concluded that the cause of explosion is the gap? NO. They just suggested the most probable cause based on their teardown. If they can easily found the cause of explosion then Samsung would have found out much earlier instead of being perplexed and grasping at straws. I still stand by that the Note 7 explosions are planned sabotage.

Just go and try to find any phone with that kind of gap in the battery compartment.. That kind of gap will cause the battery to move and shake like a maracas

        This is the stupidity of aiming at 3mm thick phones. Every person I speak with says they would rather have a 2-3 mm thicker phone than a thinner phone with smaller battery. Of course the manucacturers know better and instead of giving you better battery life they offer you the same at best with newer phone iterations.

        I hope Samsung's example will be also helpful for other companies in theie phone design process.

            i know one phone with very tight battery arrangement, its the lenovo a7000. Then can someone explain to me why this one doesn't have an exploding issue?

                from my experience with samsung, all samsung (phones and tablets) always had problem related with battery (device chare very slowly even not charging at all), even before note7 fiasco.. when I bring to samsung service center, at least 40% people there had battery related issues.. while sony, LG, lenovo device I used havent any problem at all

                      I went S7 due to specs, SD slot and ip68... but would have happily got behind ANYTHING if it were thicker with a 5000mah battery

                          Ghostwolf, 06 Dec 2016My question is why the race for "slimness"? Are all people... moreSlim sells, it's that simple. In the show room especially the slim phone is going to attract more attention. It's like the glossy black plastic ten years ago, everyone knows it attracts fingerprints but in the showroom under the lights, it'll just look better.

                            AnonD-551566, 05 Dec 2016well this explanation sounds plausible now all that's left ... morepositive, i like it ^^

                              Ghostwolf, 06 Dec 2016My question is why the race for "slimness"? Are all people... moreEasy! Because people change over the years. People not only wanted a functioning smartphone, but a pretty one as well. Form over function as they said. This had been demostrated by Samsung itself when they released the Galaxy Note edge. Although it is unique and it had lots and lots of function to it's edge display, it wasn't attractive and it didn't sell well because of it.

                              And by the time the more beautifully design Galaxy S6 edge came along, it had quickly became the most popular smartphone at the time. Even though the edge doesn't nearly had all the function like on the Note Edge, but people buy it. Why? Because it's attractive and the looks suit the high end price. Again, form over function

                              So the way I put it, a slimmer smartphone is a more attractive smartphone than a bulky and heavy one. It's one of many companies ways to raise their sales. Make their product a fashion statement.

                                  My question is why the race for "slimness"? Are all people just that limp wristed as to not be able to hold a phone more than a 1/4" thick? Seriously?
