Link: Let’s talk about the battery in smart glasses

We were eagerly snowtubing when my spouse's fully charged smart glasses suddenly died amidst recording. A lively family race to the bottom of the hill added to the fun, yet the winner remained undecided due to the unexpected gadget failure.

It turned out, smart glasses are quite vulnerable to cold weather, akin to how phone and smartwatch batteries are affected by extreme temperatures.

Unlike phones tucked safely in pockets or smartwatches under sleeves, smart glasses expose their battery-containing arms directly to the cold. This exposure likely led to their malfunction on the chilly slopes.

Meta's Ray-Bans, promising to be an all-day AI companion, falter significantly in battery life, presenting a major hurdle for mainstream acceptance. With just four hours of moderate use and features like Live AI draining the battery in 30 minutes, they aren't suited for extended wear.

Charging these glasses also poses issues since they can't be powered while worn and don't allow for battery replacement. This design choice limits their practicality over time as the battery degrades.

Improving battery life is crucial for smart glasses to become as widespread as smartphones or smartwatches. Until then, users must juggle between enhancing vision and enabling smart features. #
