Display Comparison
The Z Fold4 boasts a revolutionary foldable display, offering a tablet-like experience in a pocketable form factor. Its 1000 nits max brightness ensures excellent visibility even in direct sunlight. The A7 Duos has a standard LCD display with a decent contrast ratio, but it pales in comparison to the Z Fold4's vibrant colors and expansive screen real estate. The Z Fold4's cover screen is also a significant advantage for quick tasks.
Camera Comparison
While specific camera specs are listed as 'Photo / Video' for both, the Z Fold4's camera system is significantly more advanced, featuring larger sensors, improved image processing, and more versatile shooting modes. Expect superior image quality, especially in low light, from the Z Fold4. The A7 Duos' camera is functional but lacks the features and performance of its successor.
Performance
The Snapdragon 8+ Gen 1 in the Z Fold4 delivers blistering performance, easily handling demanding games and multitasking. The A7 Duos' Snapdragon 615 is adequate for basic tasks but struggles with more intensive applications. The Z Fold4's newer CPU architecture and faster RAM provide a noticeable performance edge.
Battery Life
Both phones offer impressive endurance ratings (83h and 101h respectively). While the A7 Duos has a slightly better endurance rating, the Z Fold4's larger battery capacity and efficient processor contribute to its longevity. The Z Fold4 also supports faster charging speeds (25W wired, 15W wireless) and reverse wireless charging.
Buying Guide
The Samsung Galaxy A7 Duos is ideal for users on a tight budget who prioritize long battery life and basic smartphone features. It's a good choice for first-time smartphone users or those needing a reliable backup device. The Samsung Galaxy Z Fold4 is for tech enthusiasts, professionals, and anyone willing to invest in a premium, innovative device with a large, foldable display and top-tier performance.
