Cap your MacBook battery at 80% while it is plugged in all day to reduce long-term battery wear
Actively discharge the battery to a lower level using Discharge mode while staying plugged in
Pause charging automatically when the battery gets too warm using the Pro Heat Protection feature
Request a one-time full 100% charge on demand with the Pro Top Up feature without changing your daily limit
Only works on supported MacBook models, check the FAQ page for compatibility before paying for the Pro version.
AlDente is a macOS menu bar application that lets you set a maximum charging percentage for your MacBook's battery. By default, macOS charges the battery to 100% whenever you plug in, but lithium-ion batteries degrade faster when kept at or near full charge for long periods. AlDente lets you cap charging at, say, 80%, so the battery stays in a healthier range even when the laptop is plugged in all day. The free version includes two features. Charge Limiter lets you set the maximum charge percentage via a slider or a text field in the menu bar. Discharge mode lets the laptop run entirely on battery even while plugged in, so you can actively bring the charge down to a lower level. The app requires macOS 11 Big Sur or later, and which specific MacBook models are supported is listed on the project's FAQ page. A paid version called AlDente Pro adds more features: Heat Protection pauses charging when the battery gets too warm, Sailing Mode maintains charge within a set range, Top Up provides a temporary full charge on demand, and a calibration mode helps correct a drifted battery meter. The Pro version is also available through a subscription service called Setapp. The README includes an important caution about battery calibration. If you keep your MacBook at a low percentage for weeks without running full charge cycles, the battery's built-in percentage meter can drift and report incorrect numbers. The fix is to run several full cycles from 0 to 100 percent to recalibrate. This repository is no longer open source. Legacy code and older releases remain on GitHub, but the current version of the software is closed-source and proprietary.
