Smart glasses combine traditional eyewear functions like vision correction, sun protection, and style with advanced technologies such as audio, cameras, sensors, AI, and communication tools. These glasses enable features like human-computer interaction and intelligent perception. Often equipped with Bluetooth and AI voice control, they are also known as AI glasses or Bluetooth glasses. Unlike earlier devices like VR headsets, smart glasses are designed to be comfortable for everyday wear, addressing a key issue with previous wearable tech.
Modern smart glasses typically offer a usage time of 4 hours or more, with standby times extending up to 10 hours or longer. When paired with a charging case, users can enjoy several days of outdoor use without worrying about battery life. These glasses are equipped with sensors, Bluetooth modules, cameras, and other components that enhance their intelligence and versatility. As smart glasses become more functional, users are also seeking longer battery life without compromising comfort. The key battery requirements for smart glasses include:
● Extended Usage Time: Batteries must support several hours of continuous use, accommodating everyday activities.
● Quick Charging: Fast charging capabilities are essential to minimize downtime and keep users active.
● Lightweight and Compact: The battery should be small and lightweight to ensure the glasses remain comfortable for prolonged wear.
● Efficient Power Management: Smart glasses require optimized power consumption to balance performance with battery longevity.
● Fast Charging Capabilities: To minimize downtime between uses.
● Durability: Batteries need to withstand frequent charging cycles without significant degradation in capacity.
