Determining the "longest supported iPhone" depends on what you mean by "supported." Here are a few interpretations and their corresponding answers:
Longest Supported by Software Updates:
The iPhone 6s and iPhone 6s Plus are the oldest iPhones to receive the latest iOS updates. Released in September 2015, these devices continue to receive software updates, including security patches and bug fixes.
Longest Supported by Apple:
Apple officially supports iPhones for a certain period, offering repairs and replacements. While this period can vary, the iPhone 6s and iPhone 6s Plus are likely among the longest supported iPhones in this category.
Longest Supported by Third-Party Developers:
While Apple focuses on software updates for newer iPhones, third-party developers might continue to support older models. This support could include app compatibility or custom modifications. Therefore, the "longest supported iPhone" by third-party developers might differ depending on specific apps or developer practices.
In summary, the iPhone 6s and iPhone 6s Plus are the oldest iPhones currently receiving official software updates from Apple. They are likely among the longest supported models in terms of both software updates and official support.
