What is True Tone?
True Tone is a feature present on most Apple devices today, from iPhone 8, iPad Gen 9 and above. This feature helps adjust the colors displayed on Iphone to match the ambient light as best as possible
This feature is based on modern sensors on the iPhone, helping to adjust the screen brightness to suit the environment, to protect the user's eyes. This is done by adjusting the white color of the screen to match the surrounding light source, resulting in a more natural image.
How does True Tone work?
Different light sources have different color temperatures, because most lights do not emit pure white light. Whether it's light from candles, fluorescent lights or sunlight, True Tone collects information from the surrounding environment and automatically adjusts the screen to match the light source around the user.
For example, when you're in a room with warm yellow light, True Tone will make the screen appear warmer in color. Conversely, when you're outdoors in blue-white sunlight, True Tone will make the screen appear cooler in color. Thanks to that, your eyes will not be glared or tired when looking at the screen.
Pros and cons of True Tone
The True Tone feature has the following advantages and disadvantages:
Advantage
- Reduce eye fatigue: Your eyes do not have to constantly adapt to different light sources, reducing strain on vision and preventing eye problems such as dryness, redness, blurriness, pain, etc.
- Create natural images: True Tone helps the screen display colors that are realistic and consistent with the human eye, making it feel like you are looking at a real piece of paper, without color distortion.
- Increase user experience: True Tone helps you have a better experience when using iPhone, especially when reading books, newspapers, viewing photos, videos… You will feel more comfortable and satisfied with your screen.
Defect
- Reduced image fidelity: True Tone can cause images on the screen to change color compared to the original, especially when you view photos, videos or graphic designs. This may affect your assessment and comparison of image quality.
- Battery and resource consumption: This tool needs to use sensors and processors to constantly adjust the color of the screen, which can drain your iPhone's battery and resources quickly. However, this difference is usually not important, but also defeats the notion that reducing the white brightness of the screen will prolong battery life.
