Overview

• iFixit reports glued batteries in both the earbuds and the case, with access requiring heat and prying that typically scar or destroy parts.
• The charging case now uses a single 1.334 Wh battery instead of a dual‑cell design, aligning with a drop in advertised case runtime from 30 hours to 24 hours.
• Each earbud contains a 0.221 Wh cell that is somewhat easier to remove once opened, yet reassembly and resealing are described as unworkable.
• New hardware changes include foam‑infused ear tips confirmed under a microscope, heart‑rate sensing, an IP57 rating, and repositioned magnets for MagSafe and Qi2.
• Repair advocates and outlets warn that typical battery wear after two to three years will push users toward replacements, contrasting Apple’s approach with more repairable models from brands like Fairphone.
