iPhone 18 Series to Drop Physical SIM Slot in Europe for Larger Battery: Leak Reveals Major Upgrades

Apple is reportedly planning a significant design shift for the upcoming iPhone 18 series in European markets. According to the latest reports, the tech giant may launch an eSIM-only version of the iPhone 18 in Europe, following the strategy it adopted for the US market starting with the iPhone 14 series.

The primary motivation behind this move is not just a push toward digital SIMs but a practical hardware advantage: internal space optimization.

eSIM Transition: Making Room for More Juice

Removing the physical SIM card tray and its internal connector frees up a small but critical amount of space inside the smartphone chassis. This extra room is reportedly being earmarked to accommodate a slightly larger battery, a move aimed at further extending the battery life of the Pro models.

• iPhone 18 Pro Max (eSIM variant): Rumored to pack a battery rated between 5,100mAh and 5,200mAh.
• iPhone 18 Pro Max (Physical SIM variant): Expected to feature a slightly smaller 5,000mAh battery due to the space occupied by the SIM hardware.

2nm A20 Pro Chip: A Power Efficiency Game Changer

The battery life is set to receive a double boost. Beyond the physical increase in capacity, the iPhone 18 Pro and Pro Max are expected to debut the A20 Pro chip, which will likely be Apple’s first processor built on TSMC’s cutting-edge 2nm manufacturing process.

• Performance: The 2nm process allows for higher transistor density, leading to faster speeds.
• Efficiency: Smaller transistors consume significantly less power, which, combined with the larger battery, could result in the best battery life ever seen on an iPhone.

Other Notable Leaks

The report also touches upon several other key upgrades for the iPhone 18 Pro lineup:

1. Satellite 5G Connectivity: With the new custom Apple C2 modem, the Pro models could support NR-NTN satellite 5G, allowing users to connect to low-Earth orbit satellites for internet access even without cellular coverage.
2. Under-Display Face ID: While the exterior design might remain similar to the iPhone 17 series, Apple is rumored to be moving Face ID components under the display, potentially resulting in a smaller Dynamic Island.
3. Variable Aperture Lens: Some leaks suggest Apple is testing a variable aperture lens for the primary camera to improve low-light photography and depth-of-field control.

Price and Availability

Despite rising component costs for RAM and new 2nm chips, analysts suggest Apple is focused on “cost management” to keep the starting prices for the iPhone 18 Pro series unchanged from the previous generation. The lineup is expected to be officially unveiled in September 2026.
