It's possible.  Read this article.

Yes, the battery could fail if you are using the phone outside the environmental requirements:

Environmental Requirements

Operating ambient temperature: 32° to 95° F (0° to 35° C)

Nonoperating temperature: -4° to 113° F (-20° to 45° C)

The battery will be negatively affected by temperatures below freezing:
