iPhone 15 may feature a more efficient battery thanks to improved display driver
The new display driver chip expected to be used in the iPhone 15 could potentially lead to a more power-efficient battery.
According to a report from Taiwan's Economic Daily News, which cites insider sources from Apple's supply chain, the battery life of the iPhone 15 and iPhone 15 Pro could be enhanced through the implementation of new display technology.
9to5Mac previously reported in December that Apple plans to use the 3nm manufacturing process for its A17 chip, which is expected to be exclusive to the iPhone 15 Pro and iPhone 15 Pro Max models. The smaller process is anticipated to enhance the efficiency of the battery.
With the latest report from Economic Daily News, it appears that the upcoming iPhone series may also feature a modified display driver chip, which could contribute to an extended battery life.
iPhone 15 series switching to 28nm display driver chip for a better battery experience, report suggests
The Economic Daily News report states that the iPhone 15 and iPhone 15 Pro may feature a display driver chip manufactured using a smaller process. Specifically, the chip could move from a 40nm to a 28nm process, resulting in improved power efficiency for the OLED display. The display driver chip is located between the main processor and the display, and it manages the activation and deactivation of pixels on the screen.
According to report, Apple's two primary suppliers for the display driver chips are planning to redesign them using the smaller 28nm manufacturing process. However, due to Apple's high demand for these chips, there may be a shortage of 28nm production capacity in the industry, which could also affect other major players in the market.
