Larger Batteries
Some reports from Korean publication The Elec points to the iPhone 12 receiving larger battery circuitry, implying that there could be a larger battery overall within the device upon release. Specifically, the Korean company ITM Semiconductor will supply the battery protection circuit required for the device, specifically Protection Module Packages circuits. This leads some to suspect that this will make room in the device for a larger battery, which would, by extension, lead to additional battery strength.
