What is true tone on iphone?

True Tone is a display technology found on many iPhones (and some iPads) that automatically adjusts the white balance of your screen to match the ambient lighting conditions. Here's what you should know:

• How it works: True Tone uses ambient light sensors to detect the color temperature of the light around you. It then subtly adjusts the white balance of the screen to make it appear more natural and less jarring on your eyes, regardless of whether you're in warm incandescent lighting, cool fluorescent lighting, or bright sunlight. The changes are subtle and aim for a more consistent viewing experience.

• Benefits: The main benefit is reduced eye strain. By adapting to the surrounding light, True Tone minimizes the difference between the screen's color temperature and your environment, making it more comfortable to look at for extended periods.

• Appearance: The changes are usually imperceptible unless you actively compare the screen with and without True Tone enabled. You won't see a drastic shift in color, just a more natural and balanced look.

• Enabling/Disabling: You can easily enable or disable True Tone in your iPhone's display settings. The exact location might vary slightly depending on your iOS version, but it's generally found under Settings > Display & Brightness.

• Not a color accuracy feature: True Tone isn't designed to improve the color accuracy of your screen in the sense of achieving a specific color profile like sRGB or Adobe RGB. Its primary goal is comfort and a more natural-looking display, not precise color reproduction.

• Battery impact: The impact on battery life from True Tone is generally negligible. The sensors and adjustments required are very low-power.

In short, True Tone is a useful feature for most users who want a more comfortable and less visually fatiguing viewing experience. If you find yourself staring at your iPhone for long periods, enabling True Tone might be beneficial.
