 Notes:
 
-- `battery.percent` is firmware-reported when available. Voltage is never converted into a fake percentage.
+- `battery.percent` is firmware-reported.
 - `battery.source` names the HID++ feature or register that supplied the value.
 - `device.name` is the firmware-reported name; `device.hid_product` is the generic Windows HID product string.
 - Unsupported sections come back as `null`.
 
-`--list-devices` and `--probe` deliberately do not print serial numbers, USB instance IDs, HID device paths, captures, or logs.

 ## Build from source
 
 You need MSVC C++ build tools (Visual Studio 2019 or 2022, x64) and PowerShell.

 The app and installer are statically linked against the MSVC CRT (`/MT`); the small startup launcher is CRT-free. The binaries depend only on core Windows DLLs (`kernel32`, `user32`, `gdi32`, `shell32`, `setupapi`, `hid`, `advapi32`, `comctl32`, `ole32`). The icon is regenerated from `assets/generate-icon.ps1` if missing.
 
-## Troubleshooting
-
-**The tray icon shows "unavailable" and the menu has nothing useful.**
-Run `SuperLightBattery.exe --probe` from a terminal. It will list which Logitech HID collections are detected and which (if any) answer HID++. Make sure the receiver is plugged in and the mouse is paired and on.
-
-**Why are there two app executables?**
-`SuperLightBattery.exe` is the real tray and CLI app. `SuperLightBatteryLauncher.exe` is the tiny windowless startup launcher shown by Startup Apps.
-
-**Icon looks blurry on a high-DPI display.**
-The tray icon renders at the shell's requested pixel size from a pixel-aligned 16×16 source and is per-monitor DPI aware. If it still looks soft, open an issue and include your DPI scaling (Settings → System → Display → Scale).
-
-**Installer says a SuperLightBattery file must sit next to the installer.**
-The tray/CLI app, startup launcher, and installer need to be in the same folder. The release zip ships them that way already; re-download the full archive if they got separated.
-
-**Tray won't exit during uninstall.**
-The installer posts `WM_CLOSE` to the tray window and waits briefly. If the tray was unresponsive at that moment, exit it manually from its right-click menu and run uninstall again. The locked files were already scheduled for deletion at next reboot.

 ## Releases
 
 Tagged releases (`v*`) trigger a GitHub Actions build on `windows-latest` that zips the binaries plus the README and LICENSE and publishes a GitHub Release.
