What we expect Apple to introduce in the fall of 2026 iPhone 18 Pro The model may come with different battery capacities depending on the country. New leak from Digital Chat Station reveals the physical SIM version to be sold in China 4.056mAhin the eSIM focused version in the US 4.288mAh It shows that there will be a battery. Although the difference seems small, this situation is explained by the fact that Apple creates more space inside in markets where it removes the SIM tray.
This information also coincides with the hardware layout that Apple followed in the latest iPhone models. The company has not used the physical SIM tray in the US since the iPhone 14 series. However, in the iPhone 17 series, this preference has become more visible on the battery side. According to information based on various previously leaked disassembly videos and European energy labels iPhone 17 Pro in physical SIM version 3.988mAhonly in eSIM version 4.252mAh carries batteries.
There is a similar difference on the iPhone 17 Pro Max side. iPhone 17 Pro Max with physical SIM 4.823mAh comes with battery capacity, eSIM only version 5.088mAh reaches capacity. Therefore, the figures spoken for the iPhone 18 Pro show that Apple continues its previous layout preference. This difference opens a separate topic in the decision process, especially for users who are considering changing phones and prioritize battery time.
According to new leak, iPhone 18 Pro is in Chinese version compared to iPhone 17 Pro 68mAhin eSIM version 36mAh It will carry a larger battery. This increase does not create a big jump on paper. However, battery life is not only determined by capacity. Processor efficiency, modem consumption, display settings and iOS optimization also directly affect daily usage time.
Apple uses more space for the battery in eSIM models
In Apple’s iPhone 18 Pro series A20 Pro processor It is suggested that he will use it. The same rumor line is that TSMC is working on this chip 2nm manufacturing process He states that he is progressing through it. A smaller production process can provide an advantage on the power consumption side. In addition, Apple’s new generation C2 5G modem It is also said that he is working on it.
These two components may affect the battery life of the iPhone 18 Pro more than the capacity increase. Especially during cellular connection, modem consumption takes up as important a share as screen time in daily use. As Apple rolls out its modems to the broader iPhone family, it can more closely control hardware and software compatibility. Still, the company has not shared official information about the iPhone 18 Pro, A20 Pro or C2 modem.
Apple’s official iPhone 17 spec sheet states that physical SIM support is not available in some markets and the devices run on eSIM technology. This information makes the iPhone 18 Pro rumor more understandable. Because when the physical SIM tray is removed, additional space for the battery appears inside the device. Apple also seems to have used this space for a larger battery in the iPhone 17 family.
On the Turkish side, the main issue will be which SIM option the iPhone 18 Pro will go on sale with. If the physical SIM version comes, users will continue to use the card they are used to, but the battery capacity may be lower. If the eSIM-only version comes, there will be a small advantage on the battery side. This choice becomes more important with carrier support and user habits.
This information about the iPhone 18 Pro is currently based on leaks from the supply chain and prototypes. There is a possibility that Apple will make capacity changes in the final hardware. Despite this, available data on the iPhone 17 series shows that only models with eSIM have room for a larger battery. Because iPhone 18 Pro battery capacitywill be one of the most followed technical details of the series as the launch approaches.
