Optimizing Mobile Game Performance and Power Consumption from a Device Manufacturer Perspective

The article explains how mobile device manufacturers can balance high frame‑rate gaming performance with reduced power draw by quantifying FPS metrics, applying temperature‑limited frame rates, using PM QoS and uclamp frequency scaling, implementing boost logic, and tailoring thread scheduling, emphasizing close collaboration with developers and silicon vendors.

Energy Aware Scheduling (EAS) in the Android Kernel: Concepts, Models, and Thread Selection

Energy Aware Scheduling (EAS) in the Android kernel uses the CPU energy model to select the most energy‑efficient CPU for each thread on heterogeneous big.LITTLE processors, considering capacity, OPP, power, and efficiency ratio; it migrates only if the migration saves more than 6% energy and overall CPU utilization stays below 80%, otherwise reverting to traditional load‑balancing.
