iPhone 17 Teardowns Confirm SIM and eSIM-Only Battery Capacities
YouTube channel REWA Technology today shared an iPhone 17 Pro teardown video, offering a closer look inside the model with a SIM card tray.

We are still waiting for repair website iFixit to share a more comprehensive teardown of the latest iPhone models, but this video provides a good look in the meantime.
The device features various internal design changes, including larger rear camera lenses. There is a new vapor chamber cooling system for improved heat dissipation. There is also an Apple-designed N1 chip for Wi-Fi 7, Bluetooth 6, and Thread.
Based on a combination of teardown videos published online, and Apple's energy labels in the EU, we have now confirmed most of the SIM and eSIM-only battery capacities across the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air lineup.

All of the iPhone 14 through iPhone 16 models lack a SIM card tray in the U.S., but Apple had simply put a piece of plastic where the tray used to be inside those devices. Starting with the iPhone 17 series, eSIM-only models sold worldwide have a larger battery that fills the space formerly occupied by either the SIM card tray or the plastic piece.
All of the iPhone 17 models are eSIM-only in the U.S., Canada, Japan, Mexico, Saudi Arabia, the United Arab Emirates, and select other countries.
