Smart glasses face battery life challenges limiting all-day use

Smart glasses, like the Ray-Ban Meta, struggle with battery life, especially in cold weather. Users report that fully charged glasses can die after about four hours of moderate use, limiting their practicality for all-day wear. The glasses' smart features, such as Live AI, significantly drain the battery, reducing usage to as little as 30 minutes. Additionally, the batteries are not replaceable, meaning users face challenges as battery performance declines over time. Current charging methods do not allow for simultaneous use and charging, further complicating the user experience. Addressing these battery issues is crucial for smart glasses to become more widely adopted.
