Gadget repair firm iFixit has stripped the iPhone 6 Plus down to its core. Apple Inc. (NASDAQ:AAPL) started selling its new phones on Friday, September 19. The iFixit technicians got their hands on the device from a physical Apple Store in Melbourne, Australia after lining up overnight. The publication said that the store had just 40 iPhone 6 Plus units, reinforcing previous reports that Apple’s suppliers have not been able to keep up with the humongous demand.

iFixit: iPhone 6 Plus Teardown Reveals Chips From Qualcomm, Skyworks

iPhone 6 Plus has 1GB RAM

The teardown revealed that the 5.5-inch iPhone 6 Plus packs a huge battery, and a fully revamped inner layout to make it thinner. Moreover, it uses chips from Skywork Solutions, Qualcomm, Avago Technologies and other companies. The Cupertino company received a whopping four million pre-orders for its new iPhone 6 and 6 Plus on the first day. More than 200 telecom carriers across the globe are supporting the new devices.

Like its predecessors, the iPhone 6 Plus has Qualcomm’s MDM9625M 4G LTE modem. The iFixit experts also found Murata WiFi module. The device uses touch screen controller made by Broadcom, and power amplifier module made by TriQuit. InvenSense supplies the gyroscope and accelerometer combo for iPhone 6 Plus. The phablet has 1GB RAM.

The phone includes a 2915mAh battery, in line with rumors before the release. That’s a major upgrade from 1560mAh battery in the iPhone 5S. In fact, Apple’s phablet has a bigger battery than Samsung Galaxy S5, which comes with 2800mAh battery. For storage, Apple uses 128GB NAND flash memory supplied by SK Hynix.

iPhone 6 Plus motion co-processor made by NXP

NXP Semiconductors supplied the NFC radio chips that will be used for Apple Pay mobile payments service. The motion co-processor in the iPhone 6 Plus was also made by NXP. The Cupertino-based tech giant designed its own main processor A8 for the phone. Apple never discloses which companies make components for its smartphones. The company also has strict regulations forbidding its suppliers from revealing the Apple-related information.

News of a supplier being chosen or rejected for Apple products may cause drastic changes in stock prices of suppliers. For instance, GT Advanced Technologies was long rumored to produce sapphire crystal display for the iPhone 6. Shares of GT Advanced Technologies had soared in run up to the iPhone 6 event. But investors were shocked to know that the company’s sapphire display was not used in the iPhone 6 or iPhone 6 Plus. As a result, shares of GT tumbled more than 13% on September 9, the day Apple announced its new phones.
