Apple is not expected to change the screen sizes of the iPhone 18 Pro and iPhone 18 Pro Max models, which will reportedly remain with 6.3 and 6.9–inch screens, respectively. Despite this, it seems the company is planning a more significant change behind the scenes – one that will not necessarily be immediately visible to the eye, but could impact battery life and the daily user experience.
According to a recently published report, Apple plans to switch to LTPO+ technology in the OLED screens of the iPhone 18 Pro series. This is an evolution of the LTPO technology that the company currently uses, which enables, among other things, the Always–On Display feature through dynamic adjustment of the refresh rate.
According to the report, most of the panels for the new Pro models will be supplied by Samsung and LG. BOE, which was a key partner in manufacturing the screens for the iPhone 17 Pro models, reportedly failed to secure Apple’s approval for the new generation after failing to meet the required quality standards for LTPO+ panels.
The main difference between LTPO and LTPO+ lies in how the transistors in the screen are managed. While standard LTPO technology uses oxide materials in some of the switching mechanisms, LTPO+ extends their use to the pixel driving mechanisms as well. The result is: Precise control over current flow and the illumination of the OLED screen.
This change could have two major impacts for users. The first is: Improved energy efficiency, which could contribute to longer battery life. The second is: Faster and more precise adaptation of the display to environmental conditions, especially in low–light settings.
According to estimates, this improvement could also reduce phenomena such as flickering or a grainy appearance on the screen when used in a dark environment. At this stage, it is still unclear whether the iPhone Ultra model, about which various rumors have circulated in recent months, will also receive the new display technology.
