Companion Android app + LSPosed/Xposed module that blocks forced shutdown at 0% and adds smart shutdown control. ⚠️ High‑risk software: this module changes system power/battery behavior. Improper settings may cause data loss or file‑system corruption if power drops unexpectedly. Features Dark theme only (no light theme) Automatic language: Russian if system language is Russian, otherwise English First-run disclaimer (must accept; decline closes the app) LSPosed recommended scope enabled (legacy-compatible) Settings are shared from the app to the hook via a ContentProvider Operating modes (only one at a time) Voltage Blocks shutdown while battery voltage is above your threshold. When voltage is ≤ threshold for the configured stability time, the module stops blocking and the system can shut down normally. Timer When the device reaches 0% and the module starts blocking shutdown, a timer starts. After N minutes, the module stops blocking and the system can shut down normally. Permanent Blocks shutdown indefinitely. The device will only turn off when you power it off manually (if possible) or when the battery physically drops power. Highest risk of sudden power loss → potential data loss. Safety floor The module includes a hard safety floor at -20%. If the system ever reports a level ≤ -20, the module will not keep blocking shutdown. LSPosed setup Install the APK. Open LSPosed Manager → Modules → enable this module. In module scope selection, enable System framework. Depending on LSPosed/ROM language, it may appear as “Android system / Система Android”. Reboot. Note: LSPosed does not allow third-party apps to silently tick scope checkboxes. The “Recommended” label only helps you select the correct scope. How it works (technical) Hooks com.android.server.BatteryService.shouldShutdownLocked() and blocks the forced critical shutdown when conditions are met. App → hook settings exchange is done via ContentProvider (more reliable than world‑readable prefs on modern Android). Usage guidance Find a safe shutdown point first. On your device, determine a voltage or time where the phone can still shut down cleanly. Too low voltage can cause a hard power cut. Prefer Voltage or Timer for daily use. Use Permanent only if you fully understand the risks.
