Shanghai's Consumer Council has urged Apple to give timely explanations concerning a series of reports of its mobile phone products spontaneously bursting into flames.

According to statistics from the council, they have received eight complaints in the last three months regarding self-combustion during normal use of Apple's iPhone 6 series products.

The eight consumers were each compensated with a new phone thanks to the reconciliation of the council.

But Apple hasn't yet given any explanation for the fires.

Earlier this year, there were also reports of iPhone 6 products shutting down even though the remaining battery was still at 50 percent.

Apple later announced that the abnormal power-off was due to battery quality, and promised a change of battery free of charge.
