Apple devices have long been part of our lives and occupy a huge part of the smartphone market. The company presented the first iPhone 2G model on 9 January 2007 at the Macworld conference in San Francisco. With the release of new models, Apple constantly strives to innovate, offering users more powerful devices with new features and improved user experience. In this article, we will not delve into the past but trace their evolution over the past 2 years from the iPhone 13 to 15.
Functionality and performance
On 14 September 2021, the company first introduced the iPhone 13 model, which contains the Apple A15 processor with 15 billion transistors. When buying the basic model, the user receives 128 GB, not 64 GB as before. To some extent, this is due to the energy-efficient A15 Bionic chip.
Two years later, in September 2023, Apple announced a new generation of smartphones – the iPhone 15. The series continues to offer four models: the basic model with a 6.1-inch iPhone 15 display; a larger version of the basic iPhone with a 6.7-inch display iPhone 15 Plus; a model with improved features, including a 6.1-inch ProMotion OLED display of 15 Pro iPhone, and the latest version of the iPhone 15 Pro Max with a 6.7-inch ProMotion OLED display. They also all feature the new A17 Bionic processor, which delivers even better performance and energy efficiency.
Battery
The battery capacity of the iPhone 13 is 3240 mAh. The model supports the MagSafe magnetic connector system, which allows you to charge your smartphone by connecting the charger to the back. Thanks to the fast wired charging technology, you can restore the device’s energy by 50% in 30 minutes.
It should be noted that the iPhone 15 model also has a capacious battery but the addition of a USB Type-C port has made it easier for owners to connect the phone to various external devices and accessories. One of the things that make the Pro and Pro Max models stand out is the ProMotion screen with a high refresh rate. It’s worth noting that the refresh rate is adaptive and variable. It can be an advantage for battery life, as this approach saves battery power.
Camera
Compared to the 12-megapixel camera system with ultra-wide-angle and wide-angle lenses in the 13, the iPhone 15 Pro offers an improved camera that provides a rich set of features for capturing highlights. It features a 12-megapixel periscope camera that offers 3x optical zoom. The Pro model has a 48-megapixel primary camera and a 12-megapixel ultra-wide-angle camera. This innovative camera uses a Tetra Prism lens to reflect light onto the sensor, allowing it to capture distant objects in high detail.
We can trace that the new iPhone 15 Pro model differs in many ways. The main characteristic of the gadget’s evolution is an increase in the level of technical equipment. Consequently, the updated version has a more powerful processor, a better camera, and a larger memory capacity. The design has not remained unchanged either, including changes in size, colour scheme, etc. Last but not the least issue is the continuous improvement of additional features, such as improved face recognition, improved display, support for new communication standards, and more.
If the price range for the iPhone 15 varies and is quite overestimated for an ordinary user, the iPhone 13 is the embodiment of high quality and can be a good deal. Currently, the estore.ua website is offering excellent quality but not very high prices: https://estore.ua/smartfony/iphone-13/.
So, over the two years, the iPhone 13 and iPhone 15 have come a long way in evolution, reflecting the advanced technology and high level of innovation that characterise Apple products. Each new model not only improves on previous features but also introduces new concepts and solutions, making them unsurpassed in the world of smartphones.
