Background Work and Battery Optimization Questions

Practical knowledge of background execution models and strategies to minimize power consumption on mobile devices. Topics include scheduling frameworks and patterns such as work manager job scheduler services and foreground services, batching and deferring work, handling platform features like doze mode and app standby, efficient location and sensor handling, minimizing wake locks and network usage, retry and exponential backoff strategies, and measuring battery impact with platform profilers. Candidates should be able to pick the right background mechanism for a requirement reason about timeliness versus power trade offs and describe concrete steps to reduce CPU GPU and network induced battery drain.
