Battery usage optimization for smart glasses

A method performed by a battery-powered electronic eyewear device for managing a battery consumption of said eyewear device based on a utilization of said eyewear device by a user, the eyewear device comprising at least one electrochromic cell,

• the method comprising:
• recording data related to the utilization of the eyewear device by the user, said utilization being based on at least the use of at least one electrochromic cell feature of the eyewear device by the user, said electrochromic cell feature being driven by at least one electrochromic cell parameter,
• analyzing said recorded data and determining at least one average usage pattern of the eyewear device by the user, said average usage pattern comprising:
• an average repartition of ideal values of the electrochromic cell parameter in the average usage pattern, and/or
• an average repartition of power consumption of the eyewear device by the user in the average usage pattern,
• adapting the management of the battery consumption of the eyewear device by piloting values of the electrochromic cell parameter based on at least the average usage pattern of the user and on charging data related to a remaining state of charge of the battery.
