The difference between an Apple 13 and an Apple 15 is really quite big. First of all, from the perspective of appearance design, Apple 15 continues Apple's consistent simple design concept, and uses a more rounded body shape, making the overall style more fashionable. The Apple 13's exterior design is more conservative and more practical. Second, in terms of screen quality, the Apple 15 is equipped with a 6.7-inch Super Retina XDR display that supports HDR10 technology, and the color performance is more vivid. In contrast, the Apple 13's screen, while also performing well, may be slightly inferior in size and color saturation.
In terms of performance, Apple 15 is equipped with a new A16 chip, using a 6 core CPU and 5 core GPU design, performance compared with A15 chip has been greatly improved. That means the Apple 15 will be faster and smoother at handling a variety of tasks and applications. The camera function is also one of the important differences between the two phones. The iPhone 15 comes with an upgraded triple-lens system that includes a wide-angle lens, an ultra-wide-angle lens and a telephoto lens for sharper, more detailed photos and videos. While the Apple 13's camera is also good, it may not be as good as the Apple 15 in terms of features and performance.
Finally, battery life is also an important aspect of user concern. The Apple 15 has a 4323mAh battery, which supports 20W wired fast charge and 15W wireless fast charge, and the battery life is significantly improved compared with the Apple 13. This means that users can use their phones for longer without having to charge them frequently. To sum up, from the appearance of the design, screen quality, performance, camera functions and battery life, the Apple 13 to the Apple 15 are very different. If you're looking for higher performance and a better experience, then the Apple 15 is definitely a choice worth considering.
