There are differences in hardware, cameras, and batteries. Further - in more detail.
Screens
The phones have different types of matrices. This is OLED on Xiaomi Mi 9 and IPS on Redmi Note 9 Pro. OLED is good at that, it gives maximum contrast, but at low brightness there can be PWM, which makes your eyes tired. Nothing like that on IPS, but the contrast is limited due to the light on black tones.
Test results with 100% backlight:
Redmi Note 9 Pro:
- White brightness: 616 cd / m2
- Black brightness: 0.487 cd / m2
- Contrast: 1265: 1
- Color Accuracy: 2.2
Xiaomi Mi 9:
- White brightness: 620 cd / m2
- Black brightness: 0.0cd / m2
- Contrast: ∞
- Color Accuracy: 1.5
Technically, the screen is cooler on Xiaomi Mi 9 because of the maximum contrast. Plus, HDR support is claimed, and under the matrix is a fingerprint scanner. On the other hand, on Redmi Note 9 Pro, the IPS matrix is without PWM, which is important for some customers.
Battery and autonomy
The difference in battery capacities is huge:
5020 mAh on Redmi Note 9 Pro
3300 mAh on Xiaomi Mi 9
Both phones come with fast chargers, which is good. Mi 9 also supports wireless charging, but the corresponding charger is not included.
Test results:
Redmi Note 9 Pro:
- Continuous calls (screen off): 43:57
- Wi-Fi web surfing (screen brightness at 200 cd / m2): 17:23 h
- Video playback (brightness 200 cd / m2): 16:45 h
- Charging speed: 80% in 30 minutes
Xiaomi Mi 9:
- Continuous calls (screen off): 23:32 h
- Wi-Fi web surfing (screen brightness at 200 cd / m2): 12:16 h
- Video playback (brightness 200 cd / m2): 16:57 h
- Charging speed: 45% in 30 minutes
Redmi Note 9 Pro simply breaks the Mi 9 in autonomy and charging speed. Not surprisingly, because Mi 9 autonomy is a weak point.
Performance Xiaomi Mi 9 And Redmi Note 9 Pro:
Smartphones use different levels of hardware. This is the flagship 7nm Snapdragon 855 processor on Xiaomi Mi 9 and the new mid-sized Snapdragon 720G chip, made using the 8nm process technology. The winner is initially obvious, just look at the test results in the Antutu 8 benchmark:
Mi 9 - 448137 points
Redmi Note 9 Pro - 279625
Antutu 8 displays overall performance. If you compare the graphics, then here Xiaomi Mi 9 will have a 2-fold advantage.
Xiaomi Mi 9 has a cool processor and a good Sony IM 586 sensor, which together guarantee high quality photos. There is also a wide-angle and telephoto camera, moreover, "shirik" with autofocus, which is rare.
On Redmi Note 9 Pro, the resolution is higher - 64 megapixels, but this does not affect the quality of the photo. The processor is weaker here, the optics are probably worse. There are wide-angle and macro cameras, no telephoto.
In good light, granularity is better on Mi 9, the amount of noise is less, however, overexposure of the frame is evident. Redmi Note 9 Pro, by contrast, underexposed the frame, which is even worse. In low light, Xiaomi Mi 9 does not have an obvious advantage, but still, the photo quality is better, which is noticeable in the latest crop.
Conclusion:
The better Xiaomi Mi 9:
- Amoled screen with maximum contrast, HDR support
- The best hardware
- There is wireless charging
- Fingerprint scanner below the screen
- Best camera
- There is a telephoto camera
Pros of Redmi Note 9 Pro:
- It is much cheaper
- IPS screen without PWM
- Higher autonomy and charging speed
- There is a macro camera
