The article examines how social practices of charging and managing the power of mobile phones are formed. The usefulness of the concept of distributed agency as a tool for the understanding of the dimensions that constitute social practices related to energy consumption is explored. Based on findings from interviews and a survey conducted with adolescents, three moments in the formation of these practices are identified: emergence of elementary battery use, acceleration of rhythm and establishment of links, and normalization. The article provides empirical evidence of the distributed agency of bodies, objects, and socio-cultural contexts in the development of these practices.
