New claims have come to the fore about Apple’s next generation smartphones, iPhone 18 Pro and Pro Max models. According to industry sources, it is predicted that the devices will not feature double-layer OLED screen technology.

Behind this technological choice, there is the risk of devices encountering heating problems. Within Apple’s current thermal management strategy, it is considered that high-brightness dual-layer displays may cause overheating.

Heating problem and thermal management

Sharing on Weibo, Digital Chat Station stated that the iPhone 18 Pro series will not use double-layer OLED screen technology. Although double-layer OLED panels are an effective solution for providing high brightness outdoors, especially in summer, they attract attention with serious heat generation.

In order to use this technology, Apple needs to follow a strategy supported by an advanced cooling system and larger batteries. In the current situation, increasing both layers of the screen to the highest brightness level can cause the temperature of the device to increase rapidly.

The company instead focuses on LTPO+ OLED display technology to increase efficiency. This technology saves energy by dynamically adjusting the refresh rate of the screen between 1Hz and 120Hz.

Design and hardware expectations

Other rumors about the iPhone 18 Pro series focus on reducing the Dynamic Island area by moving the Face ID components under the screen. While some sources argue that this change will occur, Digital Chat Station takes a more cautious approach.

Digital Chat Station states that hardware improvements such as the A20 Pro chip, variable aperture camera system and larger battery will be at the forefront rather than a design change in the iPhone 18 Pro models. It is thought that Apple has conducted A/B tests on different prototypes in this process and has not yet made the final decision.

The final specifications of the devices are expected to be shaped by Apple’s latest decisions on thermal management and display technologies. Do you think it is a correct strategy for Apple to prioritize preventing the device from heating up rather than screen brightness?
