Samsung Note 7 : the mystery of the explosions finally pierced ? – ZDNet France

initially, Samsung had promised to deliver before the end of the year, an explanation clear about the Galaxy Note 7 of which the battery has a tendency to overheat and ignite. But obviously, the investigation took a little more time than expected.

today, the world’s number one smartphones would have a clear idea of the reasons that led to this fiasco. According to Reuters, the results of this investigation may be revealed during this month of January, history of turn the page and move to the strategic launch of the Galaxy S8 scheduled between late February and April.

For the moment, speculation around the case Note 7 multiply. We can, however, build on the work of independent engineers which are also discussed in this case. Their findings seem to confirm the first few tracks : know that the battery is not the only cause.

According to Instrumental.I, the battery can not physically enough breathing

It would be nice in the face of a combination of factors : the battery would have been rendered dangerous because of the design “aggressive” of the smartphone. By “aggressive” means “too late”. In this race to the fineness (the Note is only 7.9 mm thick), Samsung might be going too far as the chassis would place pressure on the battery, all the more that the compartment that receives the battery has been reduced to the maximum.

Thus, instead of having 0.5 mm of space to “breathe” in his compartment, the battery of the Note should merely 0.1 and 0.3 mm of margin, such as shown in the photo above. However, in use, the battery has tendency to slightly inflate…

This pressure, as well as a separator physical anode/cathode end too have contributed to promote phenomenon of thermal runaway, which occurs when there is a short-circuit between the cathode and the anode, and therefore a risk of fire.

and the question now is whether this risk was not known at the the design of the device. Samsung he wanted to go too fast cut the grass under the foot to Apple and its iPhone 7, at the risk of play the Russian roulette ? For the site Instrumental.I originally this survey, there has in any case not photo : “Samsung has clearly failed in his tests of validation of the design and delivered a product dangerous.”

Samsung knows finally why the Galaxy Note 7 exploded – Presse-citron

The automaker is expected to reveal the results of its investigation this month of January, prior to the presentation of the Galaxy S8.

2016 has not been a very good year for Samsung. Then he thought finally break out its mobile division in turmoil thanks to the Galaxy Note 7, the new smartphone has been of advantage to sink the brand.

Despite an offer that could easily compete with the Apple iPhone, the Note 7 was affected by a defect which could cause explosion of batteries. Thinking it was the battery from a supplier that was in question, Samsung has recalled the product to replace the defective batteries by units assumed to be safe. But even the replacement phones, which were supposed to present default, have exploded. Because of this, Samsung was forced to remove the Note 7 of the market, without knowing the real reason for the explosions of the batteries.

However, a few days after the withdrawal of the Note 7, the boss of Samsung Mobile had promised that the company would disclose the origin of the problem, no matter what the cost. The issue is important because from this fiasco, Samsung needs to regain the trust of the public if he intends to sell other high-end smartphones, like the Galaxy S8, which is expected to be presented in February.

today, we learned that Samsung would finally the causes of these explosions of the batteries. the And according to Reuters, which cites a media outlet in south korea, the company will reveal the results of its investigation this month of January (so, before the release of the Galaxy S8).

In the meantime, the explanations of official, the theories were showering from everywhere

The experts did not wait for explanations official of Samsung to come out with their theories. The most interesting is surely one of the engineers Instrumental. They opened the hood of the smartphone and discovered ” a fundamental problem with the design of the phone itself “. “When the batteries are charged or discharged, the chemical process is migrating the Lithium and the battery swells up mechanically, and read it in their blog post. Any engineer specializing in batteries will tell you that it is necessary to leave a certain percentage of the ceiling above the battery. 10 % is a rough rule and over time, the battery will expand in this space. Our unit (ed’s note, a Galaxy Note 7) of two months, there was no ceiling : the folds and the adhesive had a thickness of 5.2 mm, resting in a pocket of 5.2 mm depth. There should be a ceiling of 0.5 mm “. According to Instrumental, it is a basic rule that could not be violated that intent.

On the other hand, other people think that it is the system of fast charging the Galaxy Note 7 which has caused the battery problems.

both courses have offered a great show to end the year 2016. Price has been one of the main actors of this meeting exciting with a total of 37 stops, 5 of which are at the expense of the gunslinger Sidney Crosby.

” He deserved probably to win, ” said coach Michel Therrien about Price. He has made big stops throughout the game to allow us to stay in the game. He has not been lucky on the third goal, the shot deflected off a player in front of him. And the winning goal, it was a throw, perfect. “

Paul Byron has scored a goal and an assist, while Alexander Radulov and Brian Flynn have written other threads on the Canadian, who now has a record of 1-1-2 since the beginning of his trip of seven games of the season.

Patric Hornqvist and Phil Kessel have been the other two markers in the camp pennsylvanian, who has signed a fourth consecutive win. In the same way as his counterpart, Marc-Andre Fleury has had an encounter very busy with 37 stops and 40 pucks sent in his direction.

” We had a big challenge in front of us and I liked the way we responded, ” noted Therrien. We have collected four points on six [from the Christmas break]. We must be satisfied with it. “

After the match, the Canadian gave Sven Andrighetto in IceCaps de St-Jean (Terre-Neuve), in the american hockey League.

The Blue-white-red will continue its journey away from the Bell Centre, with a stop in Nashville, on the 3rd of January next. Everything indicates that P. K. Subban, the victim of an injury to the upper body, will not be able to face his former team.

At the end of the confrontation in the face of Predators, there will be stops in Dallas, the next day, and at Toronto, 7 January, before the players of the Habs return to Montreal.
