The news is from the city of Federal Way (Washington) where a guy named “Rahel Mohamad” twitted about the incident.

— Rocky Mohamadali (@rocky_mohamad) November 14, 2018 He said that “This year early January I bought the iPhone and have been using it normally.” The iPhone X was in process of getting new iOS 12.1 update and when Mohamad put it on charging at a later stage, he observed a “Dark grey smoke started coming from the phone. The update was completed and as soon as the phone turned on it immediately started to smoke and caught fire.” He also said that he was using the official bundled Apple Lightning cable and a wall adapter to charge his iPhone(see the image below).

However due to some reason he had to stop the charging of his iPhone which is just before the explosion. Mohamad said, “When I held the phone it was very hot and I drop the phone immediately on the floor. Then it started to smoke.” he added.” He reached out Apple which wishes to investigate the incident further by getting Mohamad to ship the iPhone X to them. In reply to his tweet, Apple Support also said that this is definitely not expected behavior and would wish to resolve it soon. This is not the first incident of smartphones exploding. A few years back Samsung had to recall its Galaxy Note 7 after several of its units exploded while in use. Stay tuned for more.
