As has become an annual custom iFixit tore down the latest iPhone — in this case the iPhone 11 Pro Max — to see what's changed inside Apple's flagship device. The site found that the phone has 4GB of RAM, a 3969 mAh battery that adopts the L-shaped design for the first time in a Max phone, and an improved thermal management system.
Also intriguing: "We have a secondary battery connector for the first time ever in an iPhone, plugging in directly adjacent to the wireless charging coil. We're not sure what Apple was up to here. "
This additional connector, iFixit postulates, could be a record of the bilateral charging feature that was rumored before the phone's release. Pre-launch reports have claimed that the new iPhone would be able to charge AirPods wirelessly, much like Samsung's recent Galaxy phones. However, iFixit notes that Apple's published documentation indicates that the iPhone 11 Pro Max has new hardware for tracking battery performance, and that may be an alternative explanation.
Other interesting findings include a new barometric sensor design and an explanation of one way Apple achieved improved thermal performance: it's "accomplished by pulling heat from the logic board straight through several graphite layers where it dissipates into the rear case."  iFixit sells repair-related parts and services and advocates for user-performed repairs for environmental waste reduction. As with prior teardowns, the site gave the phone a repair rating. This time it was 6 out of 10, the same score given to the iPhone XS and XS Max in 2018. iFixit reported that the battery is easier to service than before, but that breaking the glass back of the phone requires replacing the entire chassis to repair.
