Revealing the iPhone 18 Pro Battery Specs
Following a recent teardown conducted by iFixit, the internal battery capacities for Apple’s latest flagships, the iPhone 18 Pro and iPhone 18 Pro Max, have finally been brought to light. While Apple famously omits specific milliamp-hour (mAh) ratings from its official marketing, focusing instead on playback duration estimates, these hands-on investigations provide the concrete data tech enthusiasts often seek.
Capacity Comparison: US Models
According to iFixit's findings for the North American market, the standard iPhone 18 Pro is equipped with a 4,288mAh battery. This represents a marginal 1% increase over the 4,252mAh unit found in the previous year's iPhone 17 Pro. Despite the modest physical size increase, the device benefits from the superior power efficiency of the new A20 chipset, resulting in an additional hour of battery life compared to its predecessor.
In contrast, the iPhone 18 Pro Max features a more substantial jump in capacity. It houses a 5,567mAh battery, which is roughly 9.4% larger than the 5,088mAh battery found in the eSIM-only iPhone 17 Pro Max. Interestingly, performance tests indicate that this larger capacity resulted in only a modest gain of about 33 minutes in total runtime.
Regional Discrepancies
The teardown also highlights a notable distinction between U.S. and European units. Due to strict EU regulations requiring public energy labeling, specifications for the European market are readily available. These documents reveal slightly different capacities for the EU models:
- iPhone 18 Pro (EU): 4,056mAh
- iPhone 18 Pro Max (EU): 5,391mAh
These differences are likely attributed to the design variations required to support physical SIM card slots, which are still standard in European models, unlike the eSIM-only configuration found in the United States.
Repair Costs and Considerations
Alongside the hardware details, it has been noted that the cost of ownership has increased. Apple has raised the out-of-warranty battery replacement fee for the iPhone 18 Pro series to $129, marking a $10 increase compared to the iPhone 17 Pro. This, combined with the $100 price hike on the base 256GB models, makes comprehensive coverage options like AppleCare+ an increasingly attractive proposition for new owners.
