Xiaomi Redmi 4X Software

Seems we have entered into the era of artificial intelligence (AI). Almost all smartphone makers have announced about their ‘smart’ systems: Meizu’s Flyme OS 6 known as intelligent thinking engine; Huawei’s EMUI 5.0 with a smart learning system. I am not talking about the LeEco Le Pro 3, which is known as the first AI phone in the globe. Of course, these systems has nothing common with IBM Watson or Google AlpheGo. Likely, we are dealing with a marketing term.

As for the Xiaomi Redmi 4X, the phone comes with MIUI8.2 pre-installed. There is a special feature called Smart Assistant. This is one of the most attractive part of Xiaomi’s OS.

Thanks to large data analysis it is capable of providing more intelligent services. Say, you can swipe from the left side of the phone in order to quickly view traffic usage, book reading progress, bus subway and so on.

Moreover, there is a WeChat payment system as well as a dozen other WeChat. Thus, MIUI8.2 offers more comfortable way of using this service. WePay or AliPay icons can be added to the quick start screen (totally 5 icons).


Other than that, MIUI8.2 provides real-time info on carrier, weather, music and so on.


Apart from the Smart Desktop Assistance, the MIUI 8.2 also comes with a new Security Centre. It uses IFTTT to perform different tasks at different time. At last, MIUI8.2 comes with updated notification bar design, sound effects like camera focus, screenshots, charging, lock screen etc.


Xiaomi Redmi 4X Performance

Generally, Qualcomm’s Snapdragon 400 series SoCs have been made for low-end devices. Identically, the Snapdragon 600 series are designed for mid-range handsets. But when the Nokia 6 was announced with a Snapdragon 430 onboard, people began paying more attention to the 400 series and looking at it differently.

As for the Xiaomi Redmi 4X, it is packed with a Snapdragon 435 chip. This is quite logical, as the previous model from this family, the Xiaomi Redmi 4 is packed with a Snapdragon 430. So the newer version is supposed to sport a newer processor. But as the model number suggests, there shouldn’t be many differences between those two CPUs. The biggest difference is the Qualcomm Gobi X6 baseband used in the Snapdragon 430. It supports Cat 4 LTE at a download speed up to for the Snapdragon 435, it comes with a Qualcomm Gobi X8 baseband supporting Cat 7 LTE at a download speed up to 300Mbps. Thus the Xiaomi Redmi 4X supports 4G+ network.

Snapdragon 435

The Xiaomi Redmi 4X is also packed with a 2GB/ 3GB RAM and 16GB / 32GB ROM. But as the 2GB RAM sounds outdated, it’s strongly recommended to get your hands on the 3GB + 32GB version. The CPU scores 43.461 at AnTuTu showing we are dealing with a low-end device with a stable performance. Be sure, it’s enough for a daily use. At last, the main advantage of this chip is 4G+ network support.

Xiaomi Redmi 4X Battery

The phone is packed with a 4100mAh capacity battery, which seems to be too large for a 5-inch screen. But thanks to it the Xiaomi Redmi 4X is capable of providing long life. For example, when WiFi is on, brightness is set at 50%, volume is at 53% and the phone is fully charged it will drop to 85% after 4 x 22 minutes of video playback.

However, do not forget we are dealing with a low-end device, and it supports only 5V / 2A charging. As the screenshot below showcases, it takes 160 minutes to charge the phone to 100%.

In comparison to the original Xiaomi Redmi 4 we won’t see many improvements in terms of hardware. But this doesn’t mean the 4th gen Redmi handsets sport weak features. Vice versa, the manufacturer focuses on batteries.

The Xiaomi Redmi 4X is the cheapest phone of the manufacturer. But this can’t be applied properly if not taking into account the time when it was launched.

And it’s quite affordable if taking into account you will acquire 4G+-enabled devices with satisfactory performance as well as good appearance.
