_{Overlay is slightly oversized on image}

Never Miss a Low Battery Warning Again

DualSense Battery Monitor is a lightweight Windows utility that automatically alerts you with a visual overlay whenever any connected PlayStation 5 DualSense controller reaches a low battery level.

• Auto-starts with Windows
• Battery monitoring every 5 seconds
• Only shows when battery is low
• Silent

Note

This only works on Windows systems

Use Case

This utility is perfect for:

• Users who use PS5 controllers on PC and want a non-intrusive, visual heads-up for low battery levels
• Multiplayer users with multiple controllers connected — the app tracks and displays each one with its own icon and battery status (Up to 4 DualSense controllers)
• Users using the DualSense controller as a pointer/input device

The app acts only when needed, showing a overlay with controller status only when a low battery is detected.

Features

• DualSense-aware overlay: Shows connected PS5 controllers and their individual battery levels.
• Low battery detection: If any controller drops below 25%, the widget appears and below 15% the effected controller's battery icon will start flashing.
• 5-second refresh rate: Battery status updates frequently and efficiently.
• Automatic Windows startup: Uses registry-based startup (no Task Scheduler required).
• Invisible when not needed: If no controller is low on battery, the widget remains hidden.
• Tested with firmware A-0630 (latest as of December 5, 2025).
• Framework-dependent and self-contained releases available.
• Built using .NET 8.0.

Common issues

Holding the PS button (Home button) for ~1-1.5 sec keeps opening Steam Big Picture Mode/Steam overlay

Go to Steam->Settings->Controller and disable "Guide button focuses Steam" and "Enable guide button chords for controller", then restart Steam (Fully exit Steam by going to Steam->Exit, and then start Steam again)
