Research Staff App: Battery Logger

Battery Logger is a lightweight widget that tracks your Garmin watch battery level over time. It automatically logs battery percentage every 5 minutes in the background and syncs readings to a server for long-term analysis. Features: - Automatic background logging every 5 minutes - Queues up to 200 readings locally when phone is out of range, then syncs when reconnected - Manual sync with a single tap - Displays current battery level, pending reading count, and last sync time - Includes device model and firmware version with each reading How it works: The widget uses a background service to capture battery readings at regular intervals. Readings are stored on the watch and sent to a server endpoint via HTTP POST. If the phone connection is unavailable, readings queue on the watch and automatically sync on the next successful connection. Requires a paired phone with Garmin Connect Mobile installed. No ads. No in-app purchases
