Xiaomi Redmi Note 3 was perhaps the most popular budget smartphone released this year. It reportedly sold a total of 600,000 units in just two months, so it is natural for fans to look forward to its successor, dubbed as the Redmi Note 4 aka Redmi Pro. The upcoming Redmi Note device is expected to have several upgrades over its predecessor.

The Chinese technology giant is expected to announce the Redmi Note 4 at its event in Beijing on Wednesday. It is also reported that the company will unveil its first Mi laptop along with the Redmi Note device, and it reportedly ressembles Apple's MacBook Air and Lenovo's ThinkPad.

There are conflicting reports on the design and looks of the Redmi Note 4. Some reports have suggested that it will sport a 5.5-inch screen, same as the Redmi Note 3, but based on OLED (Organic Light Emitting Diode). However, a Weibo user named Yang Feng said Technology (via GizmoChina) has claimed that Xiaomi's new handset will be "oversized", hinting that it will be bigger than its predecessor. 

The device is expected to be powered by either a Helio X20 deca-core SoC or a Qualcomm Snapdragon 652 processor, run Android 6.0.1 Marshmallow-based MIUI 8 operating system, and house a 16GB internal memory and a 4GB RAM. It is also reported that the handset will have a dual 13MP main camera and a 4,100mAh battery with fast charging technology.

It may be mentioned that the Redmi Note 3 was priced at Rs. 9,999 for the 16GB internal memory and 2GB RAM model, and Rs. 11,999 for the 32GB internal storage and 3GB RAM variant. It sports a 5.5-inch IPS LCD capacitive touchscreen with 1,080x1,920 pixels (403 ppi pixel density), powered by a Qualcomm Snapdragon 650 processor, runs Android 5.0.2 Lollipop based MIUI 7.0, and storage expandable up to 256GB via microSD card. It also mounts a 16MP main camera with f/2.0 aperture, phase detection autofocus and dual-LED (dual tone) flash, a 5MP front-snapper with f/2.0 aperture, and a 4,000mAh battery.
