Apple ditched the 16GB iPhone when it released the iPhone 7, making the 32GB, the phone's smallest storage option. Apple wants to continue that trend now by making the 64GB, its new smallest capacity, and having the large capacity iPhone 8, at a said storage of 256GB for photos, videos, and apps.
TrendForce also rumors reports of the new iPhone having 3 new size models and a price range for its premium model, rumored to cost over $1000.
