Two recent studies report varying performance levels in Apple’s supply chain. Bloomberg finds that, using such data, Apple’s supply chain has lost its 'mojo'. This decision to opt for OLED for the new iPhone X placed an already lean supply chain under additional strain. The switch resulted in the split launch of the iPhone 8 (old screen format) and the iPhone X (OLED). The iPhone 8 appears to be struggling and the iPhone X is arguably under-engineered, lacking in finger-print processing capabilities.
