Overview
- Apple published day-one repair guides, which direct technicians to disconnect the Battery Management System cable first to cut power.
- Battery service remains complex because Apple sells the pack preinstalled in the top-case assembly, effectively forcing a near-complete transplant for replacements.
- A small design change brings the central battery pull tabs within reach without removing the trackpad, easing part of the process.
- Many modular parts, including fans and ports, sit beneath the logic board, and display swaps still require removing an antenna bracket and multiple tiny P2 screws.
- iFixit measured a 72.6 Wh battery, slightly above Apple’s listed 72.4 Wh, underscoring minor but notable internal changes.
