Screen and Design

Screen Ratio

Both devices come on the market with Full HD+ resolution LCD panels, which tends to please due to the contrast level and color intensity. What changes between them is the size of the screen which goes from 6.53 inches to 6.67 inches. Still, with this difference, Xiaomi states that 91% of the front panel of mobile phones is occupied by the display on both phones.

Another significant change is the absence of the traditional notch in Redmi Note 9 Pro. While the Redmi Note 8 Pro had the drop-shaped feature that housed the selfies camera, in its successor, the lens is moved to a small hole centered at the top of the panel.

On the other hand, both have in common the presence of Gorilla Glass 5 on the screen, a factor that ensures greater resistance against falls and scratches. The colors in which the devices are available are also the same: grey, green, and white.


Redmi Note Camera

Although both devices have a quad-camera, there has been a small evolution in Redmi Note 9 Pro compared to its predecessor. This year’s smartphone’s camera set consists of a 64 MP wide main sensor, 8 MP ultra-wide, 5 MP macro lens, and 2 MP depth sensor. The only difference found in the Redmi Note 8 Pro camera is the macro lens, which in this case is only 2 MP. All other sensors follow the same pattern.

Other interesting features of Redmi Note 9 Pro are the photos in RAW format, which allow more accurate editing, and the presence of the document scanning mode. Both devices are capable of recording video in 4K at a speed of 30 frames per second and offer common features such as facial detection, night mode, and HDR function.

A negative point of the Redmi Note 9 Pro is the loss of quality of the selfies camera, which went from 20 MP to 16 MP in the most current phone.

Performance and Storage

Performance and Storage

Redmi Note 8 Pro comes with a MediaTek Helio G90T processor, an octa-core up to 2.05 GHz. The Redmi Note 9 Pro features Qualcomm’s Snapdragon 720G, a 2.3 GHz octa-core. Despite the small difference in speed, both processors should offer similar performance that should be satisfactory, especially for gaming.

As for memory, there are no big differences between the devices. Both offer 6 GB RAM and two storage options: 64 GB and 128 GB.

According to Xiaomi, while last year’s device allowed 10 hours of playing time, the release can support up to 13 hours of games. The manufacturer also claims that Redmi Note 9 Pro has autonomy for 16 hours of continuous navigation and 147 hours of music.

Additional Features

In common, both devices have Bluetooth 5.0, GPS, and NFC technology. Both also connect with Wi-Fi in 802.11 a/b/g/n/ac bands, besides offering 4G and dual-chip functions.

An interesting feature of Redmi Note 8 Pro is the infrared emitter, which allows transforming the mobile phone into a universal remote control for the television and air conditioning, among other electronic devices. On the other hand, the Redmi Note 9 has a compass, noise reduction microphone, and fingerprint sensor on the side.

It is worth remembering that Xiaomi has become the main target of retailers, who offer brand devices on buying and selling sites. They are devices without an invoice, without warranty, and without the certainty that they work on the 4G of 700 MHz. That’s why they are cheaper.
