According to the unconfirmed information by producer (and unfortunately, Apple cannot be expected to confirm this and apologize), there has been a very rare event, when one of the owners (known as Mrs. Wu) of the new iPhone 8 Plus exploded during charging.
It was supposed to happen when the 70% charge state of the battery was connected to the supplied charger, and then 3 minutes later the phone burst. Apple uses batteries from different manufacturers, namely Samsung SDI, Amperex Technology Limited and LG Chem. The first two (one of Samsung's subsidiaries, the second independent manufacturer) were battery suppliers to the problematic Samsung Galaxy Note 7, where batteries exploded, at least inflated, or just burned quite often.
But we need to wait, if this problem escalates in the case of Apple, or, on the contrary, we are concealed of some important fact. According to the photos, it does not look like some kind of fatal explosion with burning. Apple is currently investigating the incident.
