Historique du projet

The README states the maintainer created batt because existing tools were unsatisfactory. It focuses on predictable charge limiting, with the common use case of stopping charge around a configured maximum such as 80 percent.

batt's design is intentionally daemon-based: the README compares it to docker, with a client sending requirements to a background daemon that performs the charging control.

By 2026, the README notes a changed platform landscape: macOS 26.4 and later supports native charge limiting from 80 to 100 percent, while batt remains useful on older macOS versions or when users want limits below 80 percent.

Historique d'adoption

batt is Homebrew-packaged and its README documents `brew install batt` followed by running it as a brew service. It also offers an installation script and release binaries.

The repository page showed about 1.6k stars at enrichment time, reflecting a niche but visible Apple Silicon power-user audience.

Modes d'utilisation

Typical CLI usage is to install the daemon, check status with `sudo batt status`, set an upper charge limit with commands such as `sudo batt limit 80`, disable the limit with `batt disable` or `batt limit 100`, and optionally control adapter power.

Advanced usage includes lower and upper charge bands, MagSafe LED control, idle/sleep handling, automatic calibration, scheduled calibration, and logs under `/tmp/batt.log`.

Pourquoi les passionnés de paquets s'y intéressent

batt is interesting because it is a package-manager-distributed hardware-control tool that depends on private-feeling macOS power behavior and firmware compatibility rather than a stable cross-platform Unix API.

It also captures a packaging moment: before native macOS charge limits became broader, power users installed a daemon through Homebrew to get ThinkPad-style charge thresholds on Apple Silicon MacBooks.

Chronologie

• 2025: v0.4.1 release highlights an experimental GUI and macOS Tahoe compatibility work.
• 2026: README update says macOS 26.4 adds native charge limiting, reducing batt's necessity for some users.
• 2026: v0.7.x releases include auto-calibration and scheduling work.
