How are iPhone batteries produced? What is the difference between iPhone original battery and third-party battery?

The iPhone battery is composed of two core components, namely the protection board and the battery cell. While the model and supplier of the original iPhone battery may vary depending on the batch and production time, the supply chain distribution is roughly as follows.

Design : Apple is responsible for the design of the battery, ensuring that it meets its strict standards and requirements.

Protection board: This may be from Texas Instruments or TSMC in Taiwan.

Cells: This could be from ATL, LG or Sony.

Production: Foundries include Shenzhen Sunwoda, Huizhou Desay and Xinpu Technology.

Quality Control: All batteries produced by foundries need to go through strict quality control to ensure that they meet Apple's standards and requirements.

iPhone original battery manufacturing process

Apple issued an iPhone battery design plan and issued orders for protection boards and battery cells to cooperative suppliers.

According to the design plan, the supplier of the protection board and battery cell develops and produces the iPhone battery components that meet the standards.

Apple sends the designed battery components to the foundry for assembly, and finally produces the finished iPhone battery.

Original iPhone battery

An original iPhone battery is a battery that is officially certified by Apple, usually made by the device manufacturer or authorised supplier. These batteries have been rigorously tested and certified by Apple, ensuring that their quality and performance meet Apple's standards.

iPhone third-party battery

iPhone third-party battery refers to a battery manufactured by a third-party manufacturer according to the parameters of the device, not by the manufacturer of the device and an authorised supplier. These batteries usually do not have official authorisation and certification from the device manufacturer, so some batteries may have certain risks in terms of compatibility and safety.

Advantages and disadvantages of original batteries vs. third-party batteries

Original battery: The price is higher, but the stability is strong, there is no pop-up window, and the battery health status can be displayed.

Third-party batteries: The price is relatively low, but the quality and performance may be mixed, and the battery health status may not be shown.

Recommendations for choosing a third-party battery

Choose a certified brand: ensure that the quality and performance of the battery are guaranteed.

Pay attention to the battery health display: The latest version of iOS 18.1 allows you to view the health information of third-party batteries, but choose the brand carefully.

Consider after-sales service: Choose a reputable and reputable repair shop to ensure after-sales service and warranty service.

To sum up, users should comprehensively consider factors such as brand reputation, quality assurance, and after-sales service when choosing a third-party brand battery for iPhone to ensure the performance and safety of the battery.

It is worth mentioning that from August 1, 2024, mobile phone batteries that have not obtained 3C certification are not allowed to leave the factory, sell, import or use in China. When choosing a third-party battery, iPhone users should look for regular brand mobile phone batteries to get a reliable and safe experience.
