After spending time with the Motorola Razr Fold and Honor Magic V6, then comparing them against Samsung’s new Galaxy Z Fold 8, the hardware I appreciate most has very little to do with which device is the thinnest. The regular Galaxy Z Fold 8 has a 4,800mAh battery, while the Fold 8 Ultra steps up to 5,000mAh. The Razr Fold is only marginally thicker than the regular Fold 8, and still Motorola gives me a 6,000mAh battery and a hinge rigid enough to stay planted at different angles.
