Most of Apple’s mobile phones are produced in China, but the core designs come from the United States and are assembled in foundries.
Everyone who has used an Apple mobile phone knows that there is a line of text on the back of the Apple mobile phone: Designed by Apple in California Assembled in China. This has fully reflected Apple’s R&D and production layout.
According to statistics, for the birth of an Apple mobile phone, its parts come from all over the world, and most of the mobile phone production actually comes from China. iPhone parts are purchased globally, designed by Apple in the United States, and produced by Foxconn's foundry in mainland China, so they cannot be considered American production. This is the case with many products today, produced and sold across borders.

The origin of the Apple mobile phone trademark:
In 1976, Apple’s first logo was drawn with a pen by Ron Wayne The design inspiration comes from Newton’s discovery of the law of universal gravitation while thinking under the apple tree. Apple also wants to imitate Newton’s commitment to technological innovation. However, this logo was complex and difficult to remember. It was only used during the production of Apple I, so it was quickly abandoned by Apple.
In 1976, Jobs decided to re-appoint Rob Janov, the art director of the Regis McKenna public relations company, to redesign a better logo to match the release of Apple II. So Janov started making a black and white silhouette of an apple, but it felt like something was missing.
"I wanted to simplify the shape of the apple and take a bite on one side - a byte, right, in case the apple looks like a tomato, "Janov explained. Javov then added six colorful, horizontal bars, completing the colorful Apple logo we know today.
