Finland’s Consumer Agency is looking into how well the iPhone performs (or doesn’t) in cold weather, according to “YLE” (http://macte.ch/ljNF6). The agency ays that customers who bought an iPhone and weren’t informed about how it performs in cold weather may be entitled to return the product and ask for a refund.

The iPhone’s normal operating temperatures are between 0 and 35 degrees Celsius, and the average temperature in Helsinki is below zero for four months of the year, notes “YLE.” Although the phone can be stored in temperatures as low as -20, Apple advises users not to operate the device in freezing conditions. If they do, Apple says they run the risk of shortening battery life or causing the phone to stop working temporarily.

According to the Finland’s Consumer Agency, customers dissatisfied with their phone’s functionality in cold weather can return it to the merchant and ask for a refund — if they weren’t informed about the normal operating temperatures before they purchased the phone. The agency is compiling a list of questions for Apple in order to establish how the iPhone functions in cold weather and how best to communicate this information to customers, notes “YLE.”
