Is there an average life span of PH papers? We keep them in a drawer and they are free from any moisture.

Generally, a long time, years. Specifically, it will depend on the brand, storage and handling conditions. You can easily determine the usability by comparing the readings to a new identical paper. You can not compare between brands or types or ranges.
