Display Comparison
Neither device’s display specifications are provided, so a direct comparison is limited. However, given the Tab A8’s positioning, it likely utilizes a standard IPS LCD panel. The Doogee Tab E3 Pro, aiming for a more competitive edge, may incorporate a higher-quality panel, but without specific details like resolution, peak brightness, or color gamut coverage, it’s difficult to assess. Bezels are likely comparable, typical of tablets in this price bracket. Color accuracy will likely favor Samsung due to their display calibration expertise.
Camera Comparison
Camera details are absent for both devices. Given their market segments, we can expect basic camera setups focused on video calls and casual snapshots. The Tab A8 likely benefits from Samsung’s image processing algorithms, potentially delivering slightly more pleasing images. However, without sensor size or aperture information, a definitive comparison is impossible. It’s safe to assume neither tablet will excel in low-light photography.
Performance
The core difference lies in the chipsets. The Doogee Tab E3 Pro’s Mediatek Helio G100 (6nm) features a more modern architecture – Cortex-A76 cores – compared to the Tab A8’s Unisoc Tiger T618 (12nm) with Cortex-A75 cores. The 6nm fabrication process of the Helio G100 is significantly more efficient, leading to better thermal management and sustained performance. While both are octa-core CPUs with a similar core configuration (2x performance cores + 6x efficiency cores), the G100’s architecture provides a performance edge. The larger process node of the Unisoc T618 will likely result in more throttling under sustained load. RAM specifications are not provided, but faster LPDDR4X or LPDDR5 RAM in the Doogee would further enhance its performance advantage.
Battery Life
The Doogee Tab E3 Pro boasts an impressive 89:58h endurance rating, significantly exceeding what’s typically seen in this class. This is likely due to the efficient 6nm Helio G100 chipset. While the Tab A8’s battery capacity isn’t specified, its less efficient 12nm Unisoc T618 will require more power for the same tasks. The E3 Pro also offers 18W wired charging and 2.5W reverse wired charging, providing faster replenishment and the ability to charge smaller accessories. The Tab A8 is limited to 15W wired charging, resulting in longer charge times.
Buying Guide
Buy the Doogee Tab E3 Pro if you need a tablet for demanding tasks like light video editing, extended gaming sessions, or require exceptional battery life for travel or fieldwork. Buy the Samsung Galaxy Tab A8 10.5 (2021) if you prefer a well-known brand with a polished software experience and primarily use your tablet for casual browsing, streaming, and basic productivity tasks.
