One of the most recent incidents of this happening was when an iPhone suddenly emitted smoke in an Australian flight last year. The Australian Transport Safety Bureau did the best thing when they sent the phone back to the US for further examination on what happened.
American investigators discovered that a stray screw in the battery cavity was the cause of the smoke. It came from the 30-pin connector.
This mistake came to light after the ATSB issued a report that revealed that the iPhone’s owner had it repaired. The key factor in this is that he went to an unauthorized Apple service center and the technician who fixed the phone was not trained professionally by Apple to handle their devices.
In the report, the ATSB said, “The technical examinations found that a small metal screw had been misplaced in the battery bay of the mobile telephone; the screw puncturing the battery casing and causing an internal short circuit leading to heating and thermal runaway.”
So there you have it. One cause of a smoking iPhone is a mistake, one mistake that nearly led to a disastrous ending.
