iFixit’s annual iPhone teardown is always a great opportunity to take a peek inside Apple’s latest hardware, but this year’s edition has raised some intriguing questions. The big discovery is a second battery connector within the iPhone 11 Pro Max, which could be an indicator that the hardware was supposed to support bidirectional wireless charging at one point. iFixit also confirmed the size of the phone’s large L-shaped battery, the manufacturer of the phone’s modem, and found a hint of the amount of RAM inside Apple’s most powerful iPhone.
The second battery connector is the most interesting discovery of the teardown. Multiple rumors prior to this year’s iPhone 11 announcement suggested that Apple was preparing to equip the phones with bilateral charging to “reverse charge” AirPods, for example, when placed on the back of the new iPhones. These reports turned out to be false. However, after the phones came out, there was an unconfirmed rumor that they had the hardware to support bidirectional charging, but that the feature had been disabled in software. iFixit’s discovery isn’t conclusive: it notes that the second connector could have something to do with the iPhone 11 Pro’s battery monitoring and managing hardware.
