The Galaxy S25 and Pixel 10 should immediately copy this iPhone 17 eye protection feature
- The iPhone 17 series comes with a toggle to turn off PWM dimming, a method that lowers the display’s brightness by strobing it in short intervals.
- PWM dimming is known to cause eye strain, and disabling it eliminates the display’s flickering in low-light conditions.
- Chinese phones take the opposite approach by using an ultra-high PWM frequency.
- With the Pixel 10 Pro, Google has also increased the PWM frequency to 480Hz but it may not be enough.
Among all the iPhone 17 models that Apple unveiled this week, the iPhone 17 Pro and Pro Max grab the most limelight for their new design, improved cameras, and enhanced thermals. However, all new models come with an upgraded display, featuring parity in refresh rate across models, a peak brightness of 3,000 nits, and Ceramic Shield 2 with an anti-reflective coating. While Apple did not pass up the opportunity to boast about these upgrades, another meaningful change, left unacknowledged, has now surfaced.
All iPhone 17 models reportedly come with a hidden setting to toggle PWM (pulse-width modulation) on or off. The setting is supposedly buried among Accessibility options in iOS 26 release candidate for the iPhone 17 series, and was discovered by MacRumors.
