BatteryGuard

BatteryGuard runs as a menu‑bar utility on macOS, monitoring the system’s charge level and issuing notifications when the battery falls below a defined low threshold or exceeds a high threshold. The app’s logic is straightforward: it reminds the user to connect the charger when the charge drops under 20 percent and to disconnect it once the charge rises above 80 percent. By prompting these actions, BatteryGuard aims to keep the battery within a moderate charge window, which is suggested by research to reduce long‑term wear.

The program is intended for macOS users who want additional guidance beyond the operating system’s native battery management features. It is lightweight, running only when needed to check the current charge and display simple reminders. The design focuses on minimal intrusion, using standard macOS notification mechanisms without altering any system settings.

BatteryGuard is currently in an experimental stage, meaning it may still be refined based on user feedback. It does not modify charging behavior directly; instead, it relies on the user to act on its prompts, aligning with the charging patterns described in Battery University’s analysis of optimal battery health.
