Over the years, Apple has released numerous models, each iteration bringing changes in hardware, software,performance and design.
The iPhone series has expanded to include various models catering to different user needs and preferences, from entry-level options to high end devices.
Key innovations across the generations have included improvements in processing power, camera capabilities, display technology, and battery life, as well as the introduction of new features such as Face ID, Touch ID, augmented reality (AR), LiDAR, and 5G connectivity.
