| The importance of high refresh rates on iPhone 13 and other devices |
In recent years, people have become more interested in the high refresh rate features. This is a feature that has been introduced in dozens of Android phones from different companies, and Apple has finally started rolling it out for the Pro and Pro Max versions of the iPhone 13.
This function helps improve the overall visual experience. This is mainly because it is a function associated with the monitor. Smartphones (and public devices) with higher refresh rate screens can provide a smoother and faster experience.
The concept of refresh rate is also associated with the field of video games. There is no doubt that interest in this feature has increased after users waited for it in the iPhone 12 and iPhone 11 after Apple announced that it would finally be available in the iPhone 13 phones.
What is the refresh rate?
The scene displayed on each screen consists of many still images. It is displayed very quickly and continuously. Each image can be represented by the term "frame". The refresh rate is simply the number of images displayed per second.
The refresh rate unit is Hz, and this unit can be frame parallel. As a simple example, a monitor with a refresh rate of 120 Hz can display 120 images per second.
There are also traditional displays with a refresh rate of 60Hz, such as the iPhone 12 phones, which means that these displays can only display 60 frames per second (i.e. still images). This is a very small number compared to 120 images.
The number of tires required varies depending on the type of use. For example, movies only play at a frame rate of 24 fps because they target cinema, which is the normal frame rate. Games may need frequencies above 60 Hz for the best experience.
A high refresh rate naturally affects battery life. Because the phone uses more power to process and display all these images. Therefore, the company relied on the so-called adaptive refresh rates.
The adaptive refresh rate feature is also present in the latest iPhone 13 Pro and iPhone 13 Pro Max phones, allowing the phone to switch between extremely low and extremely high refresh rates depending on the quality of the content the user is watching. .
This is because the phone can only rely on a 60Hz refresh rate when watching YouTube videos, 24Hz when playing movies, and up to 120Hz when playing.
The importance of refresh rate in other devices
In addition, some TVs offer high refresh rate features, usually at a higher price, and these devices have the same smooth display and refresh rate benefits as above, but they also provide a better experience than smartphones because they are always connected and require power. No battery needed.
Coming back to smartphones and tablets, when they are adaptive, they benefit most from the high refresh rate as it saves battery life significantly.
On the other hand, computer monitors also have a high refresh rate of 265Hz. However, using these monitors requires a powerful graphics card to process many images.
iPhone 13 Pro refresh rate
The high refresh rate of the iPhone 13 Pro and iPhone 13 Pro Max provides a better experience from smooth browsing to gaming performance.
The mobile's adaptive refresh rate function also allows free streaming between 10Hz and 120Hz, which means the phone can still provide longer battery life despite supporting new features. This function is called ProMotion in the new iPhone and is the same technology used in the iPad Pro tablet.
