Overview
- A new slider lets users cap charging between 80% and 100% in 5% steps, found in System Settings > Battery via the info button next to Charging.
- The setting enforces a hard ceiling distinct from Optimized Battery Charging, with occasional full charges only to keep state‑of‑charge estimates accurate.
- Charge Limit appears in the Shortcuts app, enabling automations to adjust the cap based on routines or context.
- The feature is present in the macOS Tahoe 26.4 developer beta, so behavior and availability could change before public release.
- Reporting suggests Apple may limit support to Apple silicon models, and the built‑in control could reduce demand for third‑party utilities like AlDente.
