For the second time in the past week, an iPhone 4 has reportedly exploded, website Mashable reported.
In the latest incident, which happened in Brazil on Wednesday morning, the Apple smartphone short-circuited and started to burn about 40cm from a man's face as he slept.
Ayla Mota said he awoke to see the iPhone 4, which was plugged in for an overnight charge, sparking and emitting smoke.
"At dawn, I woke up seconds before witnessing the burning of my iPhone when I saw a lot of sparks and black smoke out of the cell," Mr Mota told Portuguese-language tech blog TechTudo.
"My room was full with an unbearable smell of smoke! At that moment, I turned off the power switch in the room to remove the phone from the outlet."
Mr Mota said he was unharmed.
The incident happened a day after Australian air safety authorities confirmed that they are investigating a similar occurrence last Friday, when a passenger's iPhone 4 started glowing red and emitting black smoke on board a regional flight just after it landed in Sydney.
