According to recent leaks, Apple plans to launch the iPhone 18 and iPhone 18e in the spring of 2027. Both models are expected to feature a battery capacity of 4430mAh. The internal design of the two devices shows significant similarities, suggesting a strategy to increase component commonality across the product line to optimize production efficiency and reduce costs.

The battery capacity for the iPhone 18, codenamed Taycan, is listed between 3671mAh and 4430mAh, while the iPhone 18e, codenamed Nevera, ranges from 4005mAh to 4430mAh. Sources suggest these variations may depend on whether the device includes a physical SIM card slot or relies on eSIM technology, which frees up internal space for larger battery units.

Both handsets are expected to be powered by the new A20 processor, likely manufactured using a 2nm process. Reports also indicate that the devices may utilize Apple's proprietary C2 modem, replacing previous Qualcomm-based solutions. Analyst Ming-Chi Kuo predicts that the entry-level 2027 iPhone models will feature 9GB of RAM, an increase from the current 8GB standard.

Despite shared internal components, the models will maintain differences in hardware specifications. The standard iPhone 18 is expected to retain a dual-camera system with an ultra-wide lens and a higher display refresh rate. In contrast, the iPhone 18e will likely feature a single 48MP rear camera and remain positioned as an entry-level device within the lineup.
