Display Comparison
The A73 5G features a 6.7-inch Super AMOLED display with a 120Hz refresh rate, offering vibrant colors, deep blacks, and smooth scrolling. The A7 Duos has a 5.5-inch Super AMOLED display, but lacks the high refresh rate. The A73's larger size and higher refresh rate provide a significantly better viewing experience.
Camera Comparison
The A73 5G boasts a versatile quad-camera system with a 108MP main sensor, offering significantly improved image quality, especially in low light. The A7 Duos has a 13MP main camera, which is adequate for basic photography but lacks the detail and dynamic range of the A73. The A73 also includes features like OIS (Optical Image Stabilization).
Performance
The Snapdragon 778G 5G in the A73 5G delivers a substantial performance boost over the Snapdragon 615 in the A7 Duos. The A73 handles demanding apps and games with ease, while the A7 Duos can feel sluggish at times. The A73's newer CPU architecture and 6nm process also contribute to better power efficiency.
Battery Life
