- Beauty & Skincare Mirrors (25%): Focused on AR try-on, skin analysis, etc.
- Health Monitoring Mirrors (15%): Combined with physiological sensors and AI recommendations.
2. Key Functional Requirements
- Facial recognition and smart unlocking (supported by 90% of products).
- Health monitoring features such as skin condition analysis and body fat detection.
- Voice interaction (80% product coverage).
- Multi-light adjustment with tri-color temperature becoming mainstream.
3. Technology Integration Trends
- AI + IoT: Over 90% of high-end smart mirrors integrate AI algorithms for skin modeling and health prediction.

II. Lithium Battery Pain Point Analysis
1. Battery Life vs. Power Consumption
Most built-in lithium batteries have a capacity of 200–500mAh, supporting 8–12 hours of basic features. However, when AR or large displays are active, runtime drops to 3–5 hours.
Users typically use bathroom mirrors 2–3 times a day, leading to daily charging and poor experience.
2. Environmental Adaptability
Bathroom environments often exceed 90% humidity and temperatures of 35–45°C, where standard lithium batteries may suffer from:
- Capacity degradation (15%–20%).
- Safety risks such as swelling or leakage.
3. Cost and Technical Threshold
- Battery cost accounts for 20%–30% of the total product cost, limiting entry into price-sensitive markets.
- Only 30% of products support fast charging (e.g., 5W wireless), with most still using Micro-USB.
