iPhone 8 cracks ten times in a row, two more cases of panel cracking in the US

　　Since  the official launch of iPhone 8 / iPhone 8 Plus, new phones have been cracking one after another. Yesterday, it was reported that two more cases of iPhone 8 series phone panels cracking were reported in the United States. Let's follow the mobile phone handy editor to learn more about the relevant content.

　　It is reported that the battery of an iPhone 8 Plus owned by a man in Rochester, New York, suddenly expanded and cracked when he was using the Qi wireless charger. In addition, someone on the well-known online forum Reddit posted a photo of his father's newly received iPhone 8 Plus, which expanded and cracked right after it was unboxed. As a result, Apple also replaced it with a new one.

　　Although the victim received a free replacement immediately after returning his exploded iPhone, this has already aroused public doubts.

　　Coincidentally, the media reported yesterday that an iPhone 8 also had a case in Jiaxing, China where the shell exploded after smoking while charging.

　　Including these three incidents, there have been at least 10 cases of battery expansion and shell explosion in Apple's new iPhone.

　　Apple previously stated that preliminary investigations into the explosion of the new phone showed that the battery had expanded, but it was not a serious safety incident and had nothing to do with the explosion. Detailed investigation results will be announced once confirmed.

　　Although battery swelling incidents of new phones have occurred in many mobile phone manufacturers, the battery swelling and explosion of new iPhone phones is not serious compared to the explosion of Samsung Note 7. At the same time, with the sales of iPhone 8 series in the millions, the current 10 explosion cases can be completely attributed to battery problems within the normal range, which is not enough to threaten safety issues.

　　But it is worth noting that this is the first time in the history of iPhone that a battery has exploded due to expansion. As an industry benchmark, Apple is unlikely to have problems with design and yield.

　　What is the problem?

　　Some industry insiders believe that the explosion of Apple's new products is neither a design defect nor a problem with the yield rate, but is caused by the metal middle frame and glass back cover used by Apple. The expansion space of the glass is relatively small, so cracks will appear between the glass material and the screen. This problem did not exist when a metal body was used in the past because metal has a higher load-bearing capacity.

　　One of the main reasons why iPhone8/8 Plus adopts the design of metal middle frame and glass back cover is that it adds wireless charging function for the first time. If the previous generation metal body design is continued, wireless charging will be difficult to achieve. At the same time, the wireless charging function also requires adding a coil inside the back cover of iPhone8/8 Plus, which at least increases the thickness of the phone by 0.23mm. Therefore, the reason why the new iPhone8/8 Plus exploded is likely to be indirectly caused by the first use of wireless charging.

　　However, the specific reason still needs to be officially confirmed and explained after Apple conducts a detailed investigation.
