Apple hasn’t publicly highlighted this change, but its newest Watch Series 12 and Watch Ultra 4, announced last Wednesday, may feature batteries that are easier to replace. This is suggested by an updated Product Environmental Report (PER), which now explicitly mentions replaceable batteries for these models—a detail not previously included. While Apple has long offered battery replacements through its service network, the explicit note in the report implies a potential shift toward more accessible battery replacement in the new models. Confirmation of this change will require independent analysis, such as disassembling the devices. In addition to the battery update, the environmental report outlines the materials used in the new watches. The Watch Series 12 is constructed with 40% recycled materials, including 100% recycled aluminum and cobalt, 95% recycled lithium, and recycled rare earths and titanium. Recycled steel is used in several components at a rate of 80% or higher. These efforts reflect Apple’s ongoing commitment to reducing its environmental footprint through sustainable material sourcing. The packaging for the Watch Series 12 has also been redesigned to be more compact, allowing for 10% more units to be shipped in a single container. This change is expected to reduce transportation-related emissions. Additionally, the charger now consumes 0.24 watts of power when idle at 230 volts, down from 0.12 watts previously. These improvements are part of Apple’s broader strategy to enhance energy efficiency across its product line. Apple has also updated its method for calculating carbon emissions. According to the new approach, each Watch Series 12 is estimated to produce 10 kilograms of CO2 equivalent (CO2e) in total emissions, compared to 8.1 kilograms for the previous model, the Series 11. This increase is attributed to the new calculation method, which now accounts for gross emissions rather than net emissions. The company continues to refine its environmental impact assessments to provide more transparent and comprehensive data.
