Insights gleaned from the iOS 26 candidate version reveal that the iPhone 17 Pro and iPhone 17 Pro Max have integrated a novel accessibility function. This function empowers users to deactivate Pulse Width Modulation (PWM) technology via the 'Display & Text Size' settings within the 'Accessibility' menu, with the option to manually toggle it on or off. PWM technology functions by swiftly alternating the on-and-off states of LED or OLED pixels to regulate brightness. Although it contributes to energy conservation, certain users might notice screen flickering at lower brightness settings. This flickering, when experienced over extended periods, can induce discomfort, including eye fatigue and headaches. Upon deactivating PWM, the device will switch to an alternative OLED display dimming technique, ensuring a more seamless visual output at reduced brightness levels. However, this adjustment might slightly compromise display performance under low-light conditions. Presently, this feature's availability has been confirmed solely for the iPhone 17 Pro, with no definitive word yet on whether it will be implemented across all iPhone 17 variants.
