The iFixit wizards first disassembled the brand new iPhone 11 Pro Max and came to an interesting conclusion.
Two battery connectors were found in the smartphone. Experts believe that the second is needed for two-way wireless charging.
In the switched-on smartphone, we disconnected the bottom battery connector, the device remained turned on, but stopped charging via wireless charging. It looks like this additional connector is directly connected to the coil, which can be an important feature for two-way charging!
Moreover, when we connected the cable again, our smartphone instantly displayed a warning about high temperature before returning to normal . We suspect that he lost contact with an important battery temperature sensor and disconnected; this is very similar to the two-way wireless charging heat management function.
Earlier on the network, rumors surfaced that Apple had programmatically disabled the two-way wireless charging function. If this is true, there is a chance that it will be activated in one of the next iOS updates. [MacRumors]
