What is Smartphone Power Estimation Models?
Smartphone Power Estimation Models are computational techniques that predict power consumption in smartphones using hardware sensors, system calls, and machine learning under diverse workloads.
These models enable accurate energy profiling without dedicated power meters by leveraging built-in sensors and OS traces. Key approaches include system call tracing (Pathak et al., 2011, 362 citations) and sensor-based monitoring (Lane et al., 2011, 408 citations). Over 20 papers since 2011 address validation across Android and iOS devices.
Why It Matters
Precise models optimize mobile apps to cut energy waste, critical as smartphones drive 8-10% of global ICT electricity use (Andrae and Edler, 2015, 1212 citations; Malmodin and Lundén, 2018, 323 citations). Pathak et al. (2011) showed fine-grained tracing reduces estimation error to 5%, aiding green app design. Lane et al. (2011) integrated models into wellbeing apps, lowering battery drain by 20% in real trials.
Key Research Challenges
Hardware Variability
Power draw differs across smartphone models and chipsets, complicating model portability (Pathak et al., 2011). Sensor noise and OS differences add 10-15% error in cross-device tests. Calibration for new hardware requires extensive retraining.
Fine-Grained Accuracy
Utilization-based models fail under dynamic workloads, with errors up to 93% for short bursts (Pathak et al., 2011, 362 citations). System call tracing improves granularity but increases overhead. Balancing resolution and runtime cost remains open.
Real-Time Profiling
Online estimation must run without draining battery further, unlike offline meters. Lane et al. (2011) used sensors for continuous monitoring but faced scalability limits. Integrating ML raises privacy and compute concerns.
