Comprehensive Solution & Technical Breakdown
### Preventing Battery Drain During All-Day Driver Shifts
Constant satellite GPS polling drains smartphone batteries in less than 3 hours, causing drivers to uninstall or force-close the app.
#### Battery-Saving Strategies: - **Adaptive Accuracy:** Use `Location.Accuracy.Balanced` (cell tower + Wi-Fi triangulation, ~100m accuracy) when idling, switching to `Location.Accuracy.High` only when a driver is within 2 km of destination. - **Geofencing:** Register operating system native geofences around pickup and delivery points. The phone OS wakes the app only when crossing geographic boundaries. - **Activity Recognition:** Use phone accelerometer sensors to pause GPS polling completely when the phone is stationary on a desk.
