fas-rs is a userspace implementation of Frame Aware Scheduling (FAS) for Android, written in Rust. It monitors frame rendering to dynamically control CPU performance, minimizing power overhead while keeping render times within target frame rates.

Use cases

• reduce power consumption while gaming on android without dropping frames
• dynamically tune cpu performance based on game frame rendering
• replace kernel-level FEAS with a device-agnostic userspace scheduler
• configure per-app target fps profiles for games
• extend scheduling behavior with custom plugins

When to choose

• you want frame-aware performance control on a rooted android device without kernel modifications
• you need broad device compatibility compared to MI FEAS
• you want per-game fps targets and configurable power modes

When to avoid

• your device is not rooted or does not support the required kernel interface
• you need an official gui manager for switching modes
• you only want simple static cpu governor tuning without frame monitoring
