Smart Power v0.9.1

WebUI

• Command-line output (powerctl, ctl.sh, doctor, logs, installer) is English.
• Bilingual English / 简体中文 interface with an in-page switch; defaults to the phone's language and remembers your choice.

Modes & orchestration

• One-tap Daily / Gaming / Ultra-saver modes that switch uperf, dfps, GPU cap and CPU caps together.
• Ultra-saver keeps the screen at a stable 60 Hz (touch no longer ramps the refresh rate), GPU 610 MHz, uperf powersave.
• Thermal guard: scales CPU/GPU caps down when battery ≥ 41 ℃ or CPU ≥ 62 ℃, with hysteresis.

Game profiles

• Event-driven foreground detection (logcat events), applies a game's profile within ~1 s.
• Switches the uperf global mode during games (uperf only honours per-app rules in auto), restores it afterwards and respects manual changes.
• Locks the refresh rate to an integer multiple of the in-game frame rate (e.g. 45 fps → 90 Hz) to remove judder.
• 5-second exit grace period: pulling down the notification shade does not flip profiles back and forth.

Crash-safe undervolt manager (experimental)

• Takes over the third-party Dimensity 8000/9000 undervolt module (cpuhvfs.ko): off / guard / managed.
• Load probe (no voltage change) that cross-checks the driver's voltage table against the vendor table.
• Hard limit, pre-flight checks, staged ramp, observation window, crash circuit breaker at next boot.
• Temporary → verified → permanent workflow, live readback of the real offset from the firmware table.

Charging (all off by default)

• Charge current cap, charge limit with hysteresis, gaming bypass. Only undoes changes Smart Power made itself.

WebUI & tooling

• KernelSU-style WebUI (KernelSU / APatch built-in, MMRL or KsuWebUI on Magisk): overview, games, monitor charts, performance, charging, tools.
• Read-only doctor: kernel module vermagic, SoC mismatch, voltage writers, controller conflicts, crash forensics.
• Hot install: first install and updates take effect without a reboot.
• Lightweight daemon: ≈ 1.4 % of one core with the screen on, ≈ 2.6 % while gaming (measured).
