Redmi Note 8 2021: A Refreshed Version of a Bestselling Phone
The Redmi Note 8 was one of the most popular budget phones in 2019, selling over 25 million units worldwide. To celebrate this milestone, Xiaomi launched a refreshed version of the phone in May 2021, dubbed Redmi Note 8 2021. The new model features some upgrades over its predecessor, such as a MediaTek Helio G85 chipset, a higher refresh rate display, a larger storage option, and a newer software version. However, it also comes with some compromises, such as a lower video recording resolution, fewer RAM options, fewer color choices, and a higher price tag. In this article, we will review the Redmi Note 8 2021 in detail and see how it compares to the original Redmi Note 8. We will also evaluate its pros and cons and help you decide whether it is worth buying or not.

Design and Display
The Redmi Note 8 2021 looks almost identical to its predecessor on the outside. It has a glass front and back with Corning Gorilla Glass 5 protection and a plastic frame. It measures 158.3 x 75.3 x 8.4 mm (6.23 x 2.96 x 0.33 in) and weighs 190 g (6.70 oz). It comes in three colors: Neptune Blue (the one we have for this review), Moonlight White, and Space Black.
The front of the phone features a 6.3-inch IPS LCD display with a waterdrop notch for the selfie camera. The display has a resolution of 1080 x 2340 pixels (FHD+), an aspect ratio of 19.5:9, a pixel density of 409 ppi (pixels per inch), a contrast ratio of 1500:1 (typical), a brightness of 500 nits (typical), and a refresh rate of 60 Hz. The display supports reading mode, sunlight mode, dark mode, color temperature adjustment, standard mode (sRGB), vivid mode (DCI-P3), saturated mode (wide color gamut), auto color mode (adaptive), custom white point adjustment.
The back of the phone houses a quad-camera setup arranged in a vertical module along with an LED flash. Below that is a rear-mounted fingerprint sensor that also doubles as a shutter button for taking selfies. The back also has some branding texts: "Redmi by Xiaomi" at the bottom center and "48MP AI Quad Camera" at the bottom left.

The top of the phone has a 3.5 mm headphone jack, an IR blaster, and a secondary microphone. The bottom of the phone has a USB Type-C port, a primary microphone, and a single speaker. The right side of the phone has a power button and a volume rocker, while the left side has a hybrid SIM tray that can accommodate either two nano-SIM cards or one nano-SIM card and one microSD card (up to 256 GB).
The design and display of the Redmi Note 8 2021 are decent for its price range, but not very impressive or innovative. The phone looks and feels solid and comfortable in the hand, but it is also quite heavy and slippery. The display is sharp, bright, and colorful, but it also has thick bezels, a noticeable notch, and a low refresh rate. The display also lacks any form of high dynamic range (HDR) support, which means it cannot show enhanced contrast and colors in compatible content.
Performance and Software
The Redmi Note 8 2021 is powered by a MediaTek Helio G85 chipset, which is an octa-core processor with two Cortex-A75 cores clocked at 2.0 GHz and six Cortex-A55 cores clocked at 1.8 GHz. The chipset also has a Mali-G52 MC2 GPU for graphics processing. The phone comes with either 4 GB or 6 GB of LPDDR4X RAM and either 64 GB or 128 GB of eMMC 5.1 storage. The phone also has a 4000 mAh battery that supports 18W fast charging via the included charger.
The software of the Redmi Note 8 2021 is based on Android 11 with MIUI 12.5 on top. MIUI is Xiaomi's custom skin that adds many features and tweaks to the stock Android experience. Some of the notable features of MIUI include a system-wide dark mode, an app drawer, a floating window mode, a game turbo mode, a second space mode, a privacy protection mode, a theme store, and many more. However, MIUI also has some drawbacks, such as bloatware, ads, notifications issues, bugs, and delayed updates.
We ran some benchmark tests on the Redmi Note 8 2021 to measure its performance and compare it with the original Redmi Note 8 and some other budget phones in the market. Here are the results:
Redmi Note 8 2021
361 (single-core), 1319 (multi-core)
1,600 (Sling Shot Extreme)
Redmi Note 8
311 (single-core), 1329 (multi-core)
1,100 (Sling Shot Extreme)
Realme Narzo 30A

As you can see, the Redmi Note 8 2021 has a slight edge over the Redmi Note 8 and some other competitors in terms of performance. The MediaTek Helio G85 chipset is a decent processor for gaming and multitasking, but it is not very power-efficient or future-proof. The phone can handle most casual games and apps smoothly, but it may struggle with more demanding ones. The phone also tends to heat up and throttle under heavy load. The RAM and storage options are adequate, but not very generous. The battery life is good, but not great. The phone can last for a full day of moderate use, but it may need to be charged more often if you use it heavily. The 18W fast charging is a nice feature, but it is not very fast compared to some other phones that support 30W or higher.
The performance and software of the Redmi Note 8 2021 are acceptable for its price range, but not very impressive or reliable. The phone offers some improvements over its predecessor, but it also has some limitations and issues. The software is feature-rich, but it is also bloated, ad-supported, buggy, and slow to update. The phone may not receive Android 12 or MIUI 13 updates in the future, which may affect its security and compatibility.
Camera and Audio
The Redmi Note 8 2021 has a quad-camera setup on the back and a single camera on the front. The rear cameras consist of a 48 MP main camera with an f/1.79 aperture, a 0.8 µm pixel size, a 1/2" sensor size, phase detection autofocus (PDAF), and electronic image stabilization (EIS); an 8 MP ultra-wide camera with an f/2.2 aperture, a 120 field of view (FOV), and a fixed focus; a 2 MP macro camera with an f/2.4 aperture, a 2 cm focus distance, and a fixed focus; and a 2 MP depth sensor with an f/2.4 aperture and a fixed focus. The front camera is a 13 MP selfie camera with an f/2.0 aperture, a 1.12 µm pixel size, a fixed focus, and EIS.
