BatteryCraft
by Benjiaa
BatteryCraft lowers Minecraft's power use on a MacBook so the battery lasts longer and the machine runs cooler during play.
What it does
When a MacBook runs on battery, BatteryCraft reduces the game's power draw by adjusting frame rate, render distance and simulation distance. When the charger is connected again, the original settings are restored without manual switching. Automatic profiles respond to battery level, switching to a lighter setup when the charge drops and to a critical profile when it gets very low.
The mod is a client mod, so only the player's machine needs it and servers run without it. Fabric API is required. BatteryCraft is published for Fabric only, across 17 release versions, 1.21 – 26.3, and the latest Fabric file is 1.0.0-beta.5+mc26.3 for 26.3, released on 2026-10-05 on the beta channel. The code is open source under the MIT License.
An optional HUD can show the battery percentage and estimated remaining time, and the visual settings screen is available in English and Spanish. Sodium is detected and integrated when installed. The author notes an experimental macOS thermal protection feature. The mod's documentation states that it sends telemetry and asks for administrator access, and it needs an Internet connection.
Key features
Automatic battery profiles

How it compares
Redstone Battery is a Fabric mod for 26.1.2 that runs on the client and server together, and it is open source under the MIT License. ChemPro is a Fabric mod for 1.21.1 that also runs on both sides, and it is not open source, with the license marked All rights reserved. Dynamic Flashlight is available on Fabric, Forge and NeoForge for 1.12.2 – 26.2, runs on both sides, and is not open source. BatteryCraft differs from all three in being client-side only, so no server needs it.
