Overview

Frosty optimizes battery life by freezing GMS services, applying system-wide doze enhancements, and automating screen-off behavior. Configure everything through the WebUI.

Features

• GMS Freezing: Disable GMS services across 8 categories
• App Doze: Remove any app from Android's Doze power-save exemption list. GMS is selectable here too, replacing the old dedicated GMS Doze toggle
• Deep Doze: Aggressive background restrictions for all apps (Moderate / Maximum)
• Screen Off Optimization: Disable selected connections (Wi-Fi, Bluetooth, data, location) and optionally run the RAM cleaner after a configurable screen-off delay, restores on unlock
• Kill Google Tracking: Disables GMS analytics, Clearcut telemetry, Phenotype polling, and ad tracking
• Kernel Tweaks: Scheduler, VM, network, and debug optimizations
• RAM Optimizer: ZRAM auto-tuning, LMK/LMKD/PSI thresholds, OEM reclaim disabling, VM memory params (Moderate / Maximum), configurable RAM Cleaner
• System Props: Disable debug properties to save RAM and battery
• Log Killing: Stop battery-draining log and debug processes
• Battery Saver Tuner: Customize what Android's built-in battery saver does when active

Deep Doze Levels

Both levels rewrite Doze constants, force IDLE on screen-off, run a 5-min screen-off wakelock killer, and enable JobScheduler flex-idle on Android 13+. Maximum additionally uses the restricted standby bucket (Moderate uses rare), denies WAKE_LOCK, disables the motion sensor on screen-off, and kills wakelocks immediately on apply.

RAM Optimizer

Auto-tunes ZRAM compression, LMK / LMKD / PSI thresholds, OEM reclaim nodes, and VM memory params. Maximum scales LMK weights up ~60-70% and uses more proactive LMKD/PSI thresholds.

FAQ

Q: Why are my notifications delayed?
A: App Doze and Deep Doze restrict background activity. Add your messaging apps to the Deep Doze whitelist in the WebUI.

Q: Where did GMS Doze go?
A: It's now part of App Doze. Open the App Doze picker and select GMS, same effect, unified interface.

Q: Does this work without Google Play Services?
A: Kernel Tweaks, System Props, Blur Disable, Log Killing, RAM Optimizer and Cleaner, and Deep Doze all work. GMS features require GMS.

Q: Is anything enabled after install?
A: No. Everything is off by default. Enable only what you need.
