iPhone 16 Series to Use a Stainless Steel Battery Case Due to EU Regulation

iPhone 16 Battery

In 2023, the European Parliament passed a new law that require that batteries in all household devices, including mobile phones and game consoles, be “easily disassembled and replaced” by users. This law, set to take effect in 2027, has prompted major tech innovations from leading brands. Among these, Apple’s upcoming iPhone models, the iPhone 16 series, are already making headlines. There are reports of its novel battery solution aimed at complying with the new EU rules.

Analyst Ming – Chi Kuo has provided insights into how Apple plans to adapt. Ming – Chi Kuo is a renowned Apple analyst who has accurately predicted many of Apple’s product releases and features over the past decade. He is known for his strong connections within Apple’s supply chain, which allow him to obtain data on part orders. He uses the dinfo to forecast upcoming products and sales. Kuo has now revealed the new advancement in the iPhone 16 series battery design. The new design promises both regulatory compliance and enhanced performance.

EU’s New Law on Battery Replacement

The European Parliament’s new law is a big step towards sustainability and user empowerment. By mandating that batteries in user electronics be easily replaceable, the EU aims to reduce electronic waste. The EU also aims to extend the life of these devices with this law. This move not only benefits the environment but also empowers users by giving them more control over the maintenance of their devices. The law, which comes into effect in 2027, requires brands to redesign their products to ensure that battery replacement is easy. The EU also says that changing a battery should not require epecial tools or expertise.

Apple’s Response to EU Law

Apple, known for its novel approach to tech, is already taking steps to comply with the new EU laws. According to Tianfeng International analyst Ming – Chi Kuo, the company is set to introduce new changes in its battery technology starting with the iPhone 16 series. Apple plans to use a stainless steel battery case, which will make battery disassembly easier and safer. This change is expected to reduce the difficulty of replacing the battery, aligning with the EU’s requirements.

The stainless steel battery case is a major shift in Apple’s design style. Traditionally, iPhone batteries have been encased in materials that make them difficult to replace without expert help. The new stainless steel case, however, will simplify this process. It will make it possible for users to replace the battery themselves. This change not only enhances compliance with the EU law but also offers more benefits.

One of the key pros of the stainless steel battery case is its impact on battery cell density. Ming – Chi Kuo notes that this new design can increase the battery cell density by 5-10%, while still adhering to safety laws. This trend means that future iPhones could feature batteries that last longer and perform better. Some how, this will boost the overall user experience.

Heat Dissipation

Another huge benefit of the stainless steel battery case is its solid heat dissipation and protection capabilities. The stainless steel is more effective at conducting heat away from the battery. This can improve the device’s performance and longevity. This is also important for high – performance devices like the iPhone 16 Pro Max. This is also the first model that Mr. Kuo expects to use the new battery design.

By improving heat dissipation, the stainless steel case helps to maintain optimal operating temperatures. It can also reduce the risk of overheating and extend the life of the battery. Also, the robust nature of stainless steel offers better protection against physical damage. This is one crucial aspect for the maintenance of batteries to ensure integrity and safety.

Xinwei: The Main Supplier

Ming – Chi Kuo’s analysis also spots Xinwei as the main supplier of the stainless steel battery cases for the new iPhones. This deal shows the importance of reliable and high – quality parts in achieving Apple’s design goals. Xinwei’s expertise in stainless steel ensures that the battery cases meet Apple’s tough standards for durability and performance.

Apple explores other techs

In addition to the stainless steel battery case, Apple is exploring other novel techs to simplify battery replacement. Last month, news emerged that Apple was developing a new “electrically induced adhesive release” technology. This tech aims to make it easier to detach the battery from the device. If this works out for Apple, it will make it battery replacement easier.

This tech uses electrical signals to weaken the adhesive bonds holding the battery in place. This method allows the battery to be easily removed without damaging other parts in the device. If successful, this tech could debut in at least one iPhone 16 model this year and expand to all versions of the iPhone 17 series next year.

Gradual Rollout of New Tech

Apple takes a careful, planned approach to rolling out new battery tech. The company plans to launch the stainless steel battery case and electrically induced adhesive release tech gradually. This will ensure that each new trend is well tested and refined before a wider release. This phased rollout allows Apple to address any future issues and make changes where needed. It will also ensure that the new features meet the high standards expected by users and regulators alike.

IPhone 14 Pro Max


The iPhone 16 Pro Max would likely be the first model to feature the stainless steel battery case. It will set the stage for future models. By starting with a flagship model, Apple can show the benefits of the new battery design to a wide audience. As the tech proves successful, it will extend to other models, including the entire iPhone 17 series.


The European Parliament’s new law on battery change is driving huge innovation in the tech industry, with Apple leading the charge. The launch of a stainless steel battery case and electrically induced adhesive release technology in future iPhone models shows Apple’s stance to compliance and innovation. These changes not only meet regulatory needs but also enhance battery performance, heat dissipation, and protection.
