An 80-year-old from the Paris suburbs was among eight people who said their iPhone screens cracked up, according to the AFP news agency.
Consumers in the UK, Holland and Sweden have reported similar problems, prompting an earlier EU investigation.
Apple said it was aware of the reports and was waiting to receive the handsets from the affected customers.
The firm has been accused of trying to hush-up cases of iPhones and iPods heating up or bursting into flames in the US and the UK.
Ken Stanborough and his daughter, from Liverpool, have accused the firm of trying to silence them with a gagging order after the child’s iPod exploded and the family sought a refund.
Apple reportedly offered to pay the money to Mr Stanborough, but only if he kept the terms of the settlement confidential.
It has been reported that the iPhone device’s lithium ion batteries could be the source of the problem.
An incident where the iPhone screen cracked up:
a 26-year-old security guard claimed he was hit in the eye with a glass shard when his Iphone screen cracked up.
He has said he would seek a full refund and file suit for damages.
The incidents have prompted investigations by French consumer affairs groups.
