BatteryLatte lives in your Mac's menu bar and tells you the truth about your battery - the exact charge, how healthy the cell still is after all those cycles, and what's quietly draining your power right now.
No account, no sign-up, nothing leaves your Mac. It reads straight from macOS and keeps its own local history, so you can finally see how your battery behaves over a day, a week, or a month.
Highlights
- Live charge in the menu bar - your exact battery percentage sits at the top of the screen, with a bolt icon the moment it starts charging. One glance, always current.
- Real battery health - see how much capacity is left compared to the day the battery was new, measured from the raw cell figures so it's accurate on Apple Silicon, not a rounded guess.
- A clear overview - a big charge ring, whether you're charging or running on battery, and the estimated time until full or empty, all on one calm screen.
- History that goes back weeks - chart your charge, health, and temperature over the last 6 hours, 24 hours, 7 days, or 30 days and spot patterns you'd never notice otherwise.
- Every detail, in plain sight - cycle count, full-charge and design capacity, temperature, voltage, amperage, live power draw in watts, the adapter's wattage, condition, and serial number.
- Watts in and out, right now - a live power reading shows exactly how fast you're charging or draining, so you can tell which charger or app is pulling its weight.
- Notifications on your terms - get a nudge when the battery hits a healthy charging limit (80% by default), drops too low, or runs hot. Set your own thresholds, or turn them off entirely.
- Kind to your eyes - a clean, native macOS look with light, dark, and automatic themes, plus quick search to jump straight to any panel.
- Entirely local - readings come straight from macOS and history is stored on your own machine. Nothing is uploaded, and no account is required.
How it works
Open BatteryLatte and it starts reading your battery immediately - the current charge appears in the menu bar, and the Overview screen shows your charge ring and status at a glance. In the background it quietly saves a sample every few minutes, so your History chart fills in on its own.
Want the full picture? The Details panel lays out every figure macOS knows about your battery, and Notifications let you decide when BatteryLatte should tap you on the shoulder. Set it once and let it run.
Perfect for
- MacBook owners who want to keep their battery healthy for as long as possible.
- Anyone buying or selling a used Mac who needs to check the real cycle count and battery health in seconds.
- Power users and developers who want to see live wattage and track how charge and temperature behave over time.
- People who just want peace of mind - a friendly heads-up before the battery gets too full, too low, or too hot.
