Overview

• iFixit measured 0.221 Wh batteries in each earbud and a single 1.334 Wh cell in the case, replacing the prior dual‑cell design.
• The single‑cell case helps explain the drop in total listening time from about 30 hours to roughly 24 hours without improving longevity or serviceability.
• Batteries in the buds and case are glued and sealed, with access requiring heat and prying that risks permanent damage even for technicians, raising e‑waste concerns as batteries typically fade in two to three years.
• iFixit says the case battery is somewhat easier to extract than before, yet the overall design still prevents practical repairs or reliable reassembly.
• Internal changes also reduce and reposition magnets to maintain MagSafe and Qi2 compatibility, and the foam‑infused tips show a bubbly microstructure that aims for a tighter seal.
