In this article, we will compare the differences between several iPhone models to help you understand them better. Design Generally speaking, each generation of iPhone will have a different design, which makes each iPhone look very novel and fashionable. The design of iPhone4 and iPhone4s is tougher, while the design of iPhone5 and iPhone5s is lighter and thinner. iPhone6 and iPhone6s have a fuller and rounder design, while the design of iPhone 7 is more concise and beautiful.iPhone8 follows the design style of iPhone 7, so it is not much different from it visually. iPhoneX is a milestone in recent years because it adopts a full-screen design for the first time. This design has been upgraded on iPhone Xs and iPhone Xs Max, making the overall design more exquisite. What is similar to the screen and the design is the screen. Each iPhone will have different screen sizes and resolutions. The previous generations of iPhones adopted a small screen, while iPhone6 and iPhone6s were the first iPhones with large screens. iPhone 7 and iPhone 8 adopt the same screen size and resolution, but through the comparison of screen details, it can be found that the screen color of iPhone 8 is more saturated and more realistic.iPhoneX adopts a full-screen design and a higher screen resolution, which makes the image clearer and sharper. Performance Almost every iPhone will be equipped with new chips and updated operating systems. These updates make each generation of iPhone faster and more efficient than the previous version. For example, iPhone4 and iPhone4s both use A4 chips, while iPhone 5 and iPhone 5s use A7 chips, which are much faster than A4. iPhone6 and iPhone6s are equipped with the A8 chip, which makes them run faster and consumes less power. iPhone 7 and iPhone 8 are equipped with A10 chip, which has better performance. iPhoneX adopts a new A11 chip and a new neural network engine to make its performance faster and better.Camera For those who are keen on taking photos, the camera of every iPhone is an important factor. For early iPhone users, the previous versions adopted a similar 5 MP camera, but the iPhone5s adopted an 8 MP camera, which made its shooting effect clearer. iPhone6 and iPhone6s adopt a 12-megapixel camera, which is one of the models with the strongest photo function before. iPhone7 and iPhone8 adopt a 12-megapixel rear camera, but the resolution of the front selfie camera has been improved to 7 million pixels. iPhoneX adopts a better dual-camera camera, which makes its shooting effect better. In addition to the camera, the new iPhone may also have other advanced features, such as face recognition.iPhoneX adds facial recognition technology for the first time, which allows users to unlock their phones by scanning their faces. This technology is considered a safer and faster way to unlock, because it is based on the user's unique facial data rather than password or fingerprint storage capacity. For those who like to download applications, take photos and store music, videos and other files, the storage capacity is also a key factor. The storage capacity of early iPhones is very small, but iPhone6 and iPhone6s have higher storage capacity, up to 128GB. They are also the first iPhones with such a large storage capacity. iPhone7 and iPhone8 ensure that they are not inferior to the first two models, and also have 128GB of storage space to choose from. However, iPhoneX has a storage space of up to 512GB, which is much higher than the previous model. Summarizing such a huge change is a subtle and imperceptible example of the differences between each iPhone. However, each generation of updates is more advanced and efficient than the previous version. When you are looking for a new iPhone, you can choose the most suitable model for you according to your needs. If you like taking photos, you need to choose the best model to take photos to meet your needs. If you like a safe and efficient way to unlock, you may choose an iPhone with face recognition. In general, each iPhone model has its own advantages and upgrades. Therefore, when choosing your next iPhone, you need to weigh the pros and cons by yourself and make the best choice according to your own needs.
