The Finnish Consumer Agency has told iPhone owners in the country that they may be entitled to a refund if they were not warned that cold temperatures could cause problems for the Apple phone.
The watchdog has been fielding questions from Finns who have noticed problems with the iPhone's performance in freezing conditions, a spokeswoman from the Finnish Consumer Agency confirmed to ZDNet UK on Friday.
In Helsinki, the average temperature can fall below zero for four months of the year, according to a report on the issue in YLE. While Apple says the iPhone can be stored at temperatures between -20° and 45°C, it notes it only operates between 0 and 35°C.
"Low- or high-temperature conditions might temporarily shorten battery life or cause the device to temporarily stop working properly," the company states on its support site.
Any iPhone owner who was not told about the operating temperature restrictions before buying the device can ask for a refund if they are not happy with how it is performing, the Finnish consumer watchdog has advised.
The consumer agency has contacted Apple to find out more about how the iPhone functions in colder temperatures and to investigate whether the company requires its sales staff to tell buyers about the potential problem.
