iFixit today published an iPhone 18 Pro and iPhone 18 Pro Max teardown in both article and video formats, providing a closer look inside the new devices.
The teardown confirms the battery capacities for the eSIM-only models:
- iPhone 18 Pro: 4,288 mAh (+0.8% vs. 4,252 mAh for iPhone 17 Pro)
- iPhone 18 Pro Max: 5,567 mAh (+9.4% vs. 5,088 mAh for iPhone 17 Pro Max)
eSIM-only models of the iPhone 18 Pro and iPhone 18 Pro Max are sold in the U.S., Canada, Mexico, Japan, Saudi Arabia, the United Arab Emirates, Qatar, Oman, Bahrain, and Kuwait. The devices have a SIM card tray in all other countries.
Battery capacities for iPhone 18 Pro models with SIM card trays surfaced previously.
The teardown also provides an in-depth look at the new variable aperture system on both models, the larger vapor chamber for cooling, and more.
NAND now sits inside the dual-layer logic board, which makes storage-related repairs less convenient, according to iFixit. In addition, the screen's plastic frame cracked or broke away on three of the four iPhone 18 Pro models it opened, which is a new issue that it did not face with previous models. However, iFixit said further testing is needed.
