  • Significantly brighter display (620 nits)
  • Improved contrast ratio (1487:1)
  • More modern chipset (Helio G85)

  • Slightly shorter battery endurance (102h rating)
  • Less power-efficient chipset (Helio G85, 12nm)
  • Potentially more thermal throttling under sustained load

Display Comparison

The Redmi Note 8 2021 boasts a clear advantage in display quality. Its measured peak brightness of 620 nits is a substantial leap over the Redmi Note 8T’s 450 nits, making it far more usable outdoors. The contrast ratio also improves from 1360:1 to 1487:1, resulting in deeper blacks and more vivid colors. While both phones share the same resolution, the 2021’s panel offers a more visually engaging experience, particularly for video streaming and gaming. We lack data on panel type (IPS vs. VA), but the contrast ratio suggests a VA-type panel in the 2021, which would further enhance the viewing experience.

Camera Comparison

Both devices are listed as having 'Photo / Video' capabilities, but lack specific details regarding sensor size, aperture, or image processing. Given the budget nature of these phones, it’s safe to assume similar camera performance. The inclusion of a 2MP macro camera on both is largely a marketing gimmick, offering limited practical value. Without more detailed specifications, it’s difficult to definitively declare a winner in the camera department. Image processing algorithms will likely be the differentiating factor, and user preference will play a significant role.

Performance

Under the hood, the Redmi Note 8T features the Qualcomm Snapdragon 665 (11nm), while the Redmi Note 8 2021 utilizes the MediaTek Helio G85 (12nm). While both are octa-core processors, the Helio G85 employs a different core configuration (2x Cortex-A75 & 6x Cortex-A55) compared to the Snapdragon 665 (4x Kryo 260 Gold & 4x Kryo 260 Silver). The 12nm process of the Helio G85 is less efficient than the 11nm process of the Snapdragon 665, potentially leading to slightly higher power consumption. However, the Helio G85’s Cortex-A75 cores offer a performance boost in single-core tasks. Real-world performance differences will likely be subtle, with the Helio G85 edging out the Snapdragon 665 in gaming, but the Snapdragon 665 potentially offering better sustained performance due to thermal efficiency.

Battery Life

The Redmi Note 8T holds a slight edge in battery endurance with a rating of 108 hours, compared to the Redmi Note 8 2021’s 102 hours. This difference, while not massive, suggests the Snapdragon 665’s greater power efficiency contributes to longer runtimes. Both phones support 18W wired charging, meaning charging times will be comparable. The brighter display of the Redmi Note 8 2021 will inevitably consume more power, partially offsetting the benefits of its slightly larger battery capacity (not specified in the data, but likely similar).

Buying Guide

Buy the Xiaomi Redmi Note 8T if you prioritize maximum battery life and are frequently outdoors in bright sunlight where the lower peak brightness won't be as noticeable. Buy the Xiaomi Redmi Note 8 2021 if you value a vibrant, easily visible display for media consumption and gaming, and are willing to accept a slightly shorter battery life. The 2021 is also the better option for those who want a more modern chipset, even if the performance gains aren't massive.

Frequently Asked Questions

❓ Will the Helio G85 in the Redmi Note 8 2021 overheat during prolonged gaming sessions?
The Helio G85 is a capable gaming chip, but its 12nm process is less efficient than the Snapdragon 665’s 11nm process. While it won’t likely reach critical temperatures, you may experience some thermal throttling after extended gaming, potentially leading to a slight drop in frame rates. The Redmi Note 8T might maintain more consistent performance over longer periods.
❓ Is the difference in display brightness between the two phones noticeable in everyday use?
Yes, the 150-nit difference in peak brightness is quite noticeable, especially outdoors or in brightly lit environments. The Redmi Note 8 2021’s screen will be significantly easier to see in direct sunlight, while the Redmi Note 8T’s screen may appear washed out. This is the biggest practical difference between the two devices.
❓ Does the Redmi Note 8 2021 support faster charging than the Redmi Note 8T?
No, both phones support 18W wired charging. While charging speeds will be similar, the Redmi Note 8 2021’s slightly smaller battery capacity might result in marginally faster full charge times, but the difference will be minimal.
