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.

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.
