2022: Redmi A1

On September 6, 2022, it became known that Redmi opened a line of ultra-cheap smartphones Redmi A. Its first representative was the Redmi A1 model, announced in India and costing less than 5,000 rubles. at the exchange rate for September 2022.

Redmi A1

As reported, Redmi A1 is a smartphone of the most basic level that can be imagined in 2022. Of course, it does not have a TN screen - these outdated matrices are in the distant past. The mobile phone is equipped with an IPS panel, but it cannot boast of a good amount of memory.

In India Xiaomi , it showed only one Redmi A1 package with 2 GB of RAM and 32 GB of internal memory. It is she who costs 6499 rupees or 4940 rubles. at the rate CENTRAL BANK of September 6, 2022. Whether other versions of this device will appear is still unclear. There is also no way data whether Xiaomi is going to release the Redmi A1 in. Russia

Redmi A1 will appear in stores in India on September 9, 2022. It will be available in black, blue and light green shades of the case. The case itself is made of ordinary plastic.

In appearance, the budget of Redmi A1 is given out by two factors - giant frames around the entire perimeter of the screen and the absence of a fingerprint scanner. It is neither behind nor in the power button.

The smartphone screen is a 6.52-inch IPS panel diagonally with a 1600x720 pixel resolution standard for inexpensive devices of the 2022 model year. This is HD + format. The display has a large 5 MP cutout for the front camera.

The back of the smartphone body is decorated with a dual camera block. The main sensor shoots in a resolution of 8 megapixels, and complements its 2-megapixel depth sensor for portrait images.

Those who do not like smartphones in bright shades will rejoice at the presence of Redmi A1 in the classic black version. Xiaomi took the ancient MediaTek Helio A22 processor as the basis of the Redmi A1 smartphone.

In AnTuTu 9, MediaTek Helio A22 issues about 89.4 thousand points. The result in GeekBench 5 is only 540 points in multi-core mode, and in single-core mode - even within 160. The CPU is manufactured using a 12nm process technology and produces a frequency of up to 2 GHz on four Cortex A53 cores.

The Redmi A1 uses the LPDDR4x chip as a RAM module, and all user data is stored in the eMMC 5.1 memory chip.

Other specifications of the mobile phone include two under slots, SIM cards both with support. 4G There is a single-band, Wi-Fi 5.0 module Bluetooth earphones , 3.5 mm input, as well as slow 10-watt charging for a large accumulator 5000 mAh.

The type of charging connector is unknown. Taking into account the price of Redmi A1 and the maximum charging power, it can be assumed that the smartphone uses the outdated microUSB 2.0.

The hardware capabilities of the smartphone indicate that it comes with firmware that is not overloaded with either additional shells or proprietary Xiaomi utilities. In addition, the 2 GB of RAM does not allow the Redmi A1 to run on a full version. back at OS Android Google the end of 2020, it was forbidden to install it on all devices with less or equal to 2 GB of memory.

Thus, entry-level gadgets are destined to ship with Android Go - a stripped-down version of Android, devoid of some functions, but consuming a minimum of system resources, which is critical with such a tiny amount of RAM. Google has been promoting the Android Go platform since spring 2017.

The question remains of the presence of MIUI firmware on the Redmi A1. It itself is demanding on hardware resources, so there is a possibility of its absence in this smartphone.

This is indirectly hinted at by the letter "A" in the name of the smartphone. Xiaomi has a long-abandoned MI A line consisting of three number models that run on pure Android and are unaware of MIUI's existence. In addition, at the end of summer 2022, information appeared about Xiaomi's desire to return to the release of inexpensive smartphones without its proprietary shell. True, it was about a sub-brand in addition to Redmi and Poco, but the company does not interfere with the experiment on the brands of smartphones already at its disposal.

According to the GizmoChina portal, there is still no MIUI in Redmi A1. But Android Go has been updated to version 12[1].
