Doogee Tab E3 Pro

  • Superior performance with the Mediatek Helio G100 chipset
  • Exceptional battery life (89:58h endurance)
  • Faster charging (18W) and reverse charging capabilities

  • Brand recognition is lower than Samsung
  • Display specifications are unknown

Samsung Galaxy Tab A8 10.5 (2021)

  • Well-established brand with a polished software experience
  • Potentially better color accuracy due to Samsung’s display expertise
  • Wide availability and support network

  • Less powerful Unisoc Tiger T618 chipset
  • Lower battery endurance compared to the Doogee Tab E3 Pro
  • Slower charging speed (15W)

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.

Frequently Asked Questions

❓ Will the Mediatek Helio G100 in the Doogee Tab E3 Pro handle demanding games like PUBG Mobile?
The Helio G100 is a capable chipset that should handle PUBG Mobile at medium to high settings. Its Cortex-A76 cores and 6nm process provide sufficient processing power and thermal headroom for extended gaming sessions, unlike the Unisoc T618 which may struggle with consistent frame rates.
❓ How does the 89:58h battery endurance of the Doogee Tab E3 Pro translate to real-world usage?
The 89:58h endurance rating suggests you can expect over a full day of heavy use, including video streaming, web browsing, and gaming, on a single charge. For lighter usage, such as reading ebooks or taking notes, you could potentially go several days without needing to recharge.
❓ Is the Unisoc Tiger T618 in the Samsung Galaxy Tab A8 sufficient for everyday tasks like browsing and streaming?
Yes, the Unisoc Tiger T618 is perfectly adequate for everyday tasks like web browsing, streaming videos, and using social media. However, it may exhibit slowdowns when multitasking or running more demanding applications compared to the Doogee Tab E3 Pro.
❓ Does the Doogee Tab E3 Pro support fast charging, and how long does it take to fully charge?
The Doogee Tab E3 Pro supports 18W wired charging. While a precise 0-100% charge time isn't specified, it will be faster than the Samsung Galaxy Tab A8’s 15W charging. Expect a full charge in approximately 2.5-3 hours.
