Apple may have to reduce the battery size to make room for new camera technology for 5G components and Pro models.
Both the iPhone 12 iPhone and iPhone 12 Pro have similar L-shaped logic boards.
The iPhone 12 Pro has an extra LiDAR connector for the LiDAR Scanner.
The battery used on both phones is the same, meaning there is no difference in battery capacity. The iPhone 12 and PiPhone 12 Pro use the same 2,815mAh battery. So how long it takes to fully charge will be the same.
