What Does the iFixit iPhone 18 Pro Teardown Reveal?
The repair experts at iFixit have released their teardown of the iPhone 18 Pro and iPhone 18 Pro Max. Their detailed findings were published in both an article and a comprehensive teardown video, offering tech enthusiasts a closer look inside both devices.
The internal examination confirms several critical details about the hardware layout. Among the most notable discoveries are exact battery specs for eSIM-only models, changes to internal storage components, and updates to the internal thermal systems.
iPhone 18 Pro Battery Capacities: How Big Are the Upgrades?
The disassembly officially confirms the exact battery capacities for eSIM-only models. When compared directly to the prior generation, the new battery sizes reveal distinct gains across the lineup:
- iPhone 18 Pro: 4,288 mAh (an increase of +0.8% compared to 4,252 mAh on the iPhone 17 Pro)
- iPhone 18 Pro Max: 5,567 mAh (an increase of +9.4% compared to 5,088 mAh on the iPhone 17 Pro Max)
These specific battery specs apply directly to eSIM-only models. It is worth noting that battery capacities for models with physical SIM card trays surfaced previously.
Where Are eSIM-Only iPhone 18 Pro Models Sold?
Apple sells the eSIM-only versions of the iPhone 18 Pro and iPhone 18 Pro Max in specific regions around the globe. If you buy a device in one of the following countries, it will not include a physical SIM card slot:
- United States
- Canada
- Mexico
- Japan
- Saudi Arabia
- United Arab Emirates
- Qatar
- Oman
- Bahrain
- Kuwait
In all other international markets and countries, the devices continue to ship with a traditional SIM card tray.
New Internal Features: Variable Aperture and Enhanced Cooling
Beyond battery measurements, this iPhone 18 Pro teardown highlights significant changes to key internal hardware systems. The disassembly provides an in-depth view of the mechanical and thermal adjustments engineered into both models.
First, the teardown exposes the new variable aperture system built into the camera assembly on both phones. Second, the disassembly shows a noticeably larger vapor chamber designed to assist with heat dissipation and high-performance cooling.
What Are the Main Repairability Challenges in the iPhone 18 Pro?
While the hardware upgrades bring enhanced performance, iFixit uncovered a few issues that could make self-repairs and third-party fixes more complicated.
According to iFixit, the NAND storage flash memory now sits directly inside the dual-layer logic board. This specific placement makes storage-related hardware repairs less convenient than on previous board architectures.
Additionally, technicians encountered an unusual durability concern with the screen assembly. The plastic frame surrounding the screen cracked or broke away entirely on three of the four iPhone 18 Pro models opened during testing.
This screen frame breakage is a new issue that iFixit did not experience with previous generations. However, iFixit noted that further testing is required to fully understand the root cause and frequency of this issue.
