PineLeaks, an Apple-based tipster from Twitter claims that Apple is currently testing out a couple new sensors for their next generation iPhone 12 Pro smartphone. The user mentioned that the manufacturer is considering a large 64MP sensor from Sony (presumably IMX686), that allows more light into the optics improving overall image quality in low light conditions and also getting night mode on the secondary front facing, ultra wide angle and telephoto lenses on board. Other rumors include a 10% larger battery units for the 2020 models of iPhones, mainly due to the drain caused by 5G connectivity. The leakster even claims that, Apple is trying to integrate mirrors and prisms to reflect light from the phone's Face ID sensors into the narrow top bezel or forehead in order to get rid of the notch.
