Based on industry insider leaks, Apple's upcoming iPhone 18 Pro series and the foldable iPhone Fold, slated for release in 2026, are poised to advance their card-free approach by championing eSIM technology. This move aims to free up internal space, allowing for the inclusion of larger-capacity batteries and subsequently boosting the phone's battery endurance. Notably, the iPhone Fold will completely forgo the physical SIM card slot, relying solely on eSIM. With a mere thickness of 4.5 millimeters and a battery capacity spanning from 5400mAh to 5800mAh, it has the potential to become the iPhone model with the largest battery capacity ever. Additionally, both the iPhone 18 Pro series and the iPhone Fold will be outfitted with the A20 Pro chip, delivering substantial enhancements in performance and energy efficiency. They will also incorporate the next-generation N2 wireless communication chip, offering full compatibility with the Wi-Fi 7 protocol and the latest Bluetooth standard.
