Powering the Future of Smart Glasses

The wearable electronics market is evolving rapidly, and smart glasses are emerging as one of the most iconic IoT products.
The collaboration between Ray-Ban and Meta demonstrates how cameras, microphones, speakers, and AI assistants
can be seamlessly integrated into everyday eyewear — without sacrificing style.

Behind this sleek design lies a critical component that often goes unnoticed:
the battery.
Without a compact, safe, and durable
custom lithium battery,
none of these smart features would be possible.

What Ray-Ban Meta Smart Glasses Teach Us

Based on product teardowns and industry reviews,
Ray-Ban Meta smart glasses use a lithium battery with a capacity of approximately
154–160mAh,
supporting around 4 hours of active use and up to 36 hours with a charging case.

Achieving this performance inside an ultra-slim temple arm required overcoming several key challenges:

Miniaturization: Fitting a battery into extremely narrow frame structures
Energy Density: Delivering useful runtime with very limited capacity
Safety: Ensuring thermal and electrical stability close to the user’s head
Fast Charging: Supporting quick top-ups via a compact charging case

These challenges reflect the broader demands faced by modern wearable and IoT product designers.
