The A18 chip is expected to significantly enhance the performance of the iPhone SE 4, offering improvements in processing power, AI capabilities, and battery efficiency[3][5].
**General Performance: The A18 chip in the iPhone SE 4 is expected to match the processing capabilities of the iPhone 16 series, resulting in faster app launches and smoother multitasking[3]. The chip is likely fabricated using TSMCâs advanced 3nm process, which should deliver improved performance and energy efficiency[1].
**AI and Machine Learning: The A18 chip should enable advanced AI features and improved computational photography[3]. Users can anticipate better image processing and more responsive machine learning capabilities[3]. The chip's Neural Engine and the phone's 8GB of RAM will fully support iOS 18's new AI features, such as text generation, image editing, and advanced Siri functions[2][5].
**Power Efficiency: The A18 chip's optimized power management system should improve battery efficiency, balancing performance with energy consumption to extend daily usage time[3].
**5G Modem Integration: The iPhone SE 4 will feature an Apple-designed 5G modem, marking the beginning of Apple's plan to integrate these modems into all of its cellular devices over the next three years[4]. The tight integration of Apple's modem with the A18 chip could deliver decent battery life during sub-6 usage[2].
