iPhone 15 to Use 28nm OLED Driver Chip for Improved Battery Life [Report]

Apple's new iPhone 15 series will move from a 40nm HV OLED driver chip to a 28nm HV chip which will reduce power consumption and improve battery life, according to a new report from UDN.

Besides the obvious advantages of reduced power consumption, Apple may be moving to a 28nm HV process because the wafer foundry cooperated by LX Semicon and Samsung System LSI is migrating the OLED driver chip process from 40nm HV to 28nm HV, and converting the 40nm process to other types of chips such as eFlash flash memory. This means they are reluctant to accept new orders for 40nm OLED chips.

The site also says that Apple's move to 28nm HV could result in a shortage of 28nm production capacity, noting that chip design manufacturers are beginning to compete for available 40nm and 28nm wafer foundry production capacity.


Apple's new iPhone 15 series is expected to arrive this fall. Both the base and pro models are likely to get Dynamic Island and Ceramic Shield but rumors suggest only the iPhone 15 Pro will have thinner bezels, solid state buttons, and 8GB of RAM.

The iPhone 15 Pro will probably utilize an A17 Bionic chip made with TSMC's 3nm process, while the iPhone 15 and iPhone 15 Plus will stick with the A16 Bionic and 6GB of RAM. All four models will purportedly have a USB-C port and Qualcomm's 5G Snapdragon X70 modem.

Finally, it's predicted the iPhone 15 Pro Max will feature a periscope telephoto lens for better optical zoom while the iPhone 15 and iPhone 15 Plus could get a 48MP rear camera lens.
