Android devices rely heavily on Energy-Aware Scheduling to balance battery life and performance across ARM big.LITTLE or DynamIQ CPU architectures. Kernel 4.14.117 features mature EAS code, allowing the task scheduler to predict the energy cost of running a task on a specific CPU core accurately. This results in fewer micro-stutters during UI rendering and optimized power consumption during idle states. 3. File System Performance (F2FS and ext4)
