  • Enable interval-based heart rate monitoring during low-intensity exercise to extend battery life.
  • Disable GPS when indoors or stationary to reduce high-energy location tracking.

2. Optimize On-Device Data Processing to Minimize Transmission Energy

Implement Edge Computing for Real-Time Filtering

Wireless communication (Bluetooth, Wi-Fi) is often the largest battery consumer. Use microcontrollers with embedded processing to:

  • Apply algorithms (e.g., Fast Fourier Transforms, digital filters) to extract key metrics onboard.
  • Transmit only essential events or aggregated statistics instead of continuous raw sensor streams.

Employ Event-Driven Data Sampling and Reporting

Trigger data collection and transmission based on conditions like:

  • Collision or impact detection in contact sports.
  • Threshold-based GPS activation linked to pace or movement.
  • Heart rate intensity zones that warrant increased monitoring.

This selective activation conserves battery by avoiding unnecessary sensor activity.


3. Select and Optimize Wireless Communication Protocols

Use Low-Power Wireless Standards Specifically for Sports Wearables

  • Bluetooth Low Energy (BLE): Widely adopted for low-battery, intermittent data transfers, BLE is essential for real-time performance monitoring.
  • ANT+: Offers efficient sensor-to-device communication favored in fitness technology.

Reduce Data Transmission Frequency and Payload Size

  • Compress and encode sensor data (delta encoding, quantization) before sending.
  • Batch multiple readings together to reduce transmission overhead.
  • Schedule data sync intelligently—preferably during user downtime or charging periods.

Implement Adaptive Communication Strategies

Dynamically tune transmission power and frequency based on:

  • Battery level.
  • Signal strength.
  • Priority of data (e.g., critical alerts vs. routine stats).

For example, scale back updates during low activity to conserve energy.


4. Employ Advanced Battery Management and Hardware Design
