How to Optimize Code Editors (Zed / VSCode) for Battery Life on macOS

Optimizing Zed and VSCode for Maximum MacBook Battery Life

Modern GPU-accelerated code editors like Zed or Electron-based VSCode can drain the battery quickly on older MacBooks patched with OCLP.

Optimization Guide:

  1. Disable GPU Acceleration in VSCode: Run VSCode with --disable-gpu or edit settings to disable hardware acceleration if it causes high CPU/GPU spikes.
  2. Adjust Zed Renderer: Configure Zed's rendering backend to use low-power modes if available in settings, or restrict the frame rate.
  3. Limit Background Indexing: Disable automatic project indexing on startup for large directories in both editors.

Original Question: "Zed vs VSCode in terms of Battery Life"

I have a MacBook Pro from mid-2014 with Sonoma 14.8.3, an Intel Quad Core i7 processor, 16 GB of RAM, and an Nvidia GT 750M graphics card. I wonder which program would make my Mac last longer if I only used the Intel iGPU. Does anyone have experience with this? Or someone have a even better lightweight Code Editor suggestion?
