True Tone on iPhone is a display feature that adjusts the screen’s color and brightness to match the surrounding light. This technology uses sensors to detect ambient light conditions and automatically modifies the display’s white balance. True Tone aims to make colors appear more natural and reduce eye strain by adapting the screen to different lighting environments.
Apple introduced True Tone with the iPad Pro in 2016 and later incorporated it into iPhones, starting with the iPhone 8 and 8 Plus. The feature works continuously in the background, making subtle adjustments to maintain a consistent viewing experience as lighting conditions change. Users can enable or disable True Tone through the Settings app or Control Center on compatible devices.
True Tone differs from Night Shift, another display feature on iPhones. While Night Shift reduces blue light emission to help with sleep patterns, True Tone focuses on color accuracy and natural-looking images. Both features can work together to enhance the overall viewing experience on iPhone screens.
How True Tone Works
At its core, True Tone uses advanced multi-channel sensors to measure the color temperature and brightness of your surrounding environment. It then automatically adjusts the white balance on your screen so that whites appear consistent in any lighting. This means your iPhone display subtly shifts from cool blue tones under fluorescent lights to warmer hues in softer, incandescent lighting—all in real time.
The goal isn’t just cosmetic. This adaptive shift reduces the harsh contrast between screen and surroundings, which can ease eye strain and improve the overall legibility of content. Whether you’re reading late at night or scrolling through photos on a sunny afternoon, True Tone is designed to make the screen feel more natural—like you’re looking at something on paper rather than a backlit digital display.
Why True Tone Matters
One of the most compelling benefits of True Tone is how it elevates the day-to-day user experience without requiring any interaction. It just works. For people who frequently switch between indoor and outdoor settings or use their phone in varied lighting, True Tone ensures colors remain comfortable and consistent. This is particularly valuable for reading, messaging, browsing, or editing photos, where lighting can dramatically alter perception.
It’s not about increasing vibrancy or contrast like some display technologies aim to do. Instead, True Tone focuses on realism and comfort—delivering what your eyes naturally expect from their surroundings.
True Tone vs Night Shift and Dark Mode
While True Tone adapts to ambient light, it’s different from Night Shift and Dark Mode. Night Shift adjusts the display’s color temperature toward warmer tones based on the time of day, aiming to reduce blue light exposure in the evenings. Dark Mode changes the interface’s background to black or dark gray to save battery and be easier on the eyes in low light.
True Tone, however, is always active during display use—adjusting dynamically based on real-time lighting conditions, regardless of the time or app in use. Many users find using all three together gives them the most comfortable experience: True Tone for environmental adaptation, Night Shift for evening use, and Dark Mode for focused night viewing.
True Tone and Third-Party Repairs
Until recently, replacing your iPhone screen with a third-party component often meant losing True Tone functionality. The system relies on factory calibration that most non-Apple service providers couldn’t replicate, leading to a grayed-out True Tone toggle or unexpected display behavior.
However, in mid-2024, Apple made a quiet but significant shift. It enabled iPhones to re-enable True Tone on third-party replacement displays—even if they aren’t Apple originals. The feature won’t perform exactly the same without the calibration data, but it gives users more flexibility when choosing repair options. And if you don’t like the result? You can simply toggle it off in Settings.
How to Enable or Disable True Tone
Via Settings
- Open the Settings app.
- Tap Display & Brightness.
- Toggle the True Tone switch on or off based on your preference.
Via Control Center
- Swipe down from the top-right corner of your screen (on Face ID iPhones).

What If True Tone Looks Too Warm?
Some users report that True Tone gives their display a yellowish tint, especially when compared to devices with the feature disabled. This is normal—True Tone’s goal is to mimic the lighting around you. But if the warmer look bothers you, especially when editing photos or watching videos with precise color needs, disabling it can return the screen to a cooler, more “digital” white.
That said, your eyes do tend to adjust over time. Many users who initially disliked True Tone find they appreciate the subtler, more natural tones after a few days of regular use.
Does True Tone Affect Battery Life?
True Tone itself has a minimal impact on battery life. It’s a sensor-driven feature that works in the background with the help of existing display management hardware. However, if you’re using True Tone alongside high screen brightness or other intensive features like HDR or ProMotion, the cumulative effect could lead to faster battery drain. On its own, though, True Tone is optimized to be energy-efficient.
Which iPhones Support True Tone?
True Tone was first introduced on the 9.7-inch iPad Pro in 2016 and came to the iPhone lineup with the iPhone 8 and iPhone X in 2017. Today, nearly every iPhone model—from the iPhone 8 up to the latest iPhone 15 series—supports True Tone, including the iPhone SE models.
Final Thoughts
True Tone may be one of the iPhone’s more understated features, but its impact is real—especially for people who use their phones for long periods or in varied environments. By adapting the display to match your surroundings, it helps reduce eye strain and deliver a more natural viewing experience. And now, with expanded support for third-party screens, it’s more accessible than ever.
