Redmi Note 9 5G: Device Overview:

The Xiaomi Redmi Note 9 5G features a 6.53 inch IPS display with an FHD+ resolution of 2430×1080 pixels. It is powered by the MediaTek Dimensity 800U processor, which is like the MediaTek alternative of the Qualcomm Snapdragon 765G. This processor is the reason why Xiaomi can keep the price low for a 5G phone while maintaining high performance. To handle multitasking, we get 6GB of RAM on the device with an internal storage of 128GB. The storage is expandable via a microSD card up to 512GB.

In terms of optics, we get a triple camera setup at the back. This includes a 48MP primary sensor with an f/1.79 lens, a second 8MP ultrawide sensor with an f/2.2 lens, and a third 2MP sensor with an f/2.4 lens. Coming to the front, we get to see a 13MP primary camera in a hole punch design on the top left corner of the screen.


Connectivity options for the phone include Wi-Fi 802.11 a/b/g, GPS, Bluetooth v5.10, USB Type-C, Wi-Fi Direct, 3G, 4G, and 5G. We also get all the basic sensors like the accelerometer, ambient light sensor, gyroscope, and proximity sensor. Powering all of this is a 5000 mAh battery that supports proprietary fast charging out of the box. The Redmi Note 9 5G is released in four color options: Cloud Ink Grey, Flowing Shadow Purple, and Outside the Castle Peak.
