Everything Battery Guard does
Six pillars, each one a place macOS stops short. Click any feature for the full story.
Custom battery alerts
macOS only warns you at 10% and 5%, then nags. Battery Guard lets you build your own alert rules — fire at 80% to unplug, at 40% to find a charger, at 20% before a meeting — each with its own banner style, sound, and a screen-edge glow you can't miss.
- Unlimited low-battery and charged-enough rules
- Per-rule sound, banner position, and border glow
- Plugged / unplugged and temperature warnings
- A full-screen critical warning across every display
Alerts at any level, with their own sound, position, and glow.
Battery health tracking
Battery Guard samples your battery in the background and keeps a long history. See your health trend over time, watch cycle count and temperature, and get a forecast of how many months until you cross the 80% replacement threshold.
- Health, capacity vs. design, and cycle count
- 24h / 7-day / 14-day history charts
- Replacement forecast fit from your own data
- Exportable PDF health certificate for resale
Capacity, cycles, and temperature, charted over time.
A menu bar icon you like
Pick exactly what your menu bar shows: charge percentage, time remaining, health, temperature, an icon alone, or an iPhone-style battery glyph with the number drawn inside. Color follows your theme, with optional green/yellow/red status coding.
- Battery-indicator or minimal icon styles
- Number drawn inside the glyph, iPhone-style
- Auto / light / dark tint
- Optional status-color coding
Charge %, time left, health, or an iPhone-style glyph.
Usage insights
Go beyond a single percentage. Battery Guard charts how much battery you actually use each day, your screen-on time, and a heatmap of when you charge — over the last 24 hours, 7 days, or 14 days — so you can spot patterns and habits.
- Daily energy-use and battery-level charts
- Screen-on and runtime insights
- Charging heatmap to spot your patterns
- 24-hour, 7-day, and 14-day ranges
Daily usage, screen-on time, and a charging heatmap.
Desktop widgets
Keep your battery in view without opening anything. Battery Guard's small and medium desktop widgets show charge, health, and time remaining, with a ring gauge or a big percentage and an accent color to match your style.
- Small and medium desktop widgets
- Ring gauge or large percentage
- Optional health and time-remaining
- Accent colors to match your style
Charge, health, and time-left, pinned to your desktop.
Auto-dismiss macOS pop-ups
When you've set up Battery Guard's tailored alerts, macOS's own low-battery banners are just noise. Battery Guard quietly closes them the moment they appear, so the only battery notification you see is the one you designed.
- Automatically dismisses system battery banners
- Leaves every other notification untouched
- No cursor movement — uses the banner's own action
- Entirely on-device
Closes Apple's battery banners so yours is the only one.
