New hints about the iPhone 18 Pro are sparking discussions. A recent leak provides specific details for the first time about the battery capacity of the upcoming Apple smartphone. It’s not just about the size of the energy storage. A possible change in the available model variants could also be significant for customers in Europe.
Battery Sizes Leaked
Apple traditionally does not comment on rumors before unveiling new devices. Nevertheless, months before an expected presentation in September, more and more information about the next iPhone generation is emerging.
According to the Weibo leaker “Digital Chat Station,” Apple is planning two different battery variants for the iPhone 18 Pro. The decisive factor is the SIM technology used.
The leak suggests that the model with a traditional SIM card will have a battery with 4,056 milliampere-hours. The version with eSIM, on the other hand, is expected to have a battery with 4,288 milliampere-hours. The difference is thus clearly noticeable. Compared to the iPhone 17 Pro, the overall capacity is expected to grow only moderately, yet differences between the two versions would emerge.

Europe Could Receive eSIM Models for the First Time
According to the leak, the planned availability of the devices is even more interesting than the pure battery values. Apple is reportedly planning to offer pure eSIM variants in Europe for the first time.
So far, only models with a physical SIM card have been available here. According to the current information, these are expected to be equipped with the smaller battery. If Apple starts selling the eSIM versions in the European market, buyers here could benefit from the larger battery capacity for the first time.

There is no official confirmation of these plans yet. The report relies solely on the leaker’s information.
Next-Generation Chip
In addition to the battery, the new hardware could also influence the runtime. According to current information, the iPhone 18 Pro is expected to be equipped with the A20 Pro chip.
TSMC is said to manufacture the processor using the 2-nanometer process. According to the leak, the new chip generation promises significantly higher energy efficiency. Together with the larger battery, this could lead to longer runtimes in everyday use.
Whether these claims will be confirmed remains to be seen. Apple has not yet officially confirmed the information about the iPhone 18 Pro.
