Ese is a native Swift battery manager for Mac that lives in your menu bar and tells you what your battery will actually do — not just the percentage macOS already shows.
Key Features
Predict, Don't Guess
- Empty or full time based on how you are using your Mac right now
- Extra minutes if you quit a heavy app — calculated from that app's share of real system watts
- Suggested plug-in time, derived from empty time and when you usually unplug
- Discharge curve in the dropdown, with a projected path
- Menu bar can show the clock time (e.g., "16:40") instead of a raw percentage
- Alerts when drain is unusually fast (the whole Mac or one app), with one-tap quit
- Alert when the battery pack runs hotter than your threshold and hotter than this Mac usually runs
Protect the Battery
- Charge limit (60–95%) so the pack isn't held at 100% all day
- One-tap "charge to full this time" before a trip — the limit returns when you unplug
- Optional: charge to full once before the hour you usually unplug (off by default)
- Health forecast: estimates when battery health may reach Apple's 80% service mark, with 80% and 90% limit scenarios
- Insights for 7 / 30 / 90 days: time plugged in, time above 80% charge, daily temperature, and cycles
