Apple makes new models every year. Some models are very powerful. Others are smaller or cheaper. The iPhone 17 is one new model. As of July 2025, people have bought over 3 billion iPhones. This makes Apple a very big phone seller.

Phones have changed a lot over time. Early models had one button on the front. Later models used Touch ID. This is a sensor that reads your fingerprint. Newer models use Face ID. This is a way to unlock the phone with your face.
