iFixit is in the process of posting its iPad 2 teardown, and has found several small changes inside. Most notably, the iPad 2 uses a 3.8V, 25 watt-hour battery, compared to the 3.75V, 24.8 watt-hour battery in the original.
Multiple Broadcom chips were found inside the device, including a Microcontroller, capacitive touchscreen controller, and a combination Wi-Fi/Bluetooth chip. Finally, the A5 processor inside iFixit’s unit had manufacture dates of late January and mid-February 2011, indicating that production was ramping up through the launch, and the processor carries the marking APL0498, compared to the APL0398 of the A4.
