The Xiaomi Redmi 4 Pro Review

The Xiaomi Redmi 4 Pro Review. It is a new Xiaomi low/mid level smartphone with very interesting hardware specs. Many people consider this phone as the new best-buy device in a price range around $177-$208. You can find the Xiaomi Redmi 4 Pro sold around $177 – $208. The price is really interesting because the hardware specs are not so low-level, in fact by hardware specs we could consider it as a mid-range device.

The dimensions are quite small and also the bundle is very small; as you can see we only have the phone, the USB cable and the battery charger (5V-2A). There is not anything else like earphones because the manufacturer wants to keep the price as low as possible.

There is also a small metal pin that is used to remove the SIM/SD tray, here you can put a NANO-SIM and a MICRO-SIM or a MICRO-SIM and a MicroSD up to 128GB.

The Xiaomi Redmi 4 Pro is quite cheap but hardware specifications are really interesting, the CPU is a Qualcomm Snapdragon 625, 8 cores at 2GHz. There are 3GB of RAM and 32GB of ROM, the ROM can be expanded with a MicroSD card up to 128GB.

Connectivity is the same of other smartphones (Wifi, LTE etc.) but the 800MHz frequency is not supported. In conclusion we can say that the hardware is really really good if compared to the low price of the phone.

The Xiaomi Redmi 4 Pro Review3

Talking about materials and assembling quality, the Xiaomi Redmi 4 Pro is entirely build with metal except for two small pieces of plastic in the point where radio-antennas are attached. The front glass is quite good and quite resistant but not so oleophobic, you can solve this problem using proper oleophobic screen protectors. The front glass has a particular design with 2.5D edges (which means that they are rounded); the same design is adopted for the rear body that is rounded, this gives you a good feeling when using the phone.

The smartphone is not so thick but also not so slim, the battery is huge so to fit it into the Xiaomi Redmi 4 Pro had to increase a little bit the thickness but this is an acceptable compromise because battery life is amazing. The edges of the phone are built with metal and also the power button and the volume rocker are metallic.

On the top is the audio jack, the microphone and an IRDA port, on the bottom there is a standard micro-USB connector (no Type C) and the speaker.

On the left side there is only the slot to insert MicroSIM+NanoSIM or the MicroSIM+MicroSD; The fingerprint sensor is works well, like all other fingerprint sensors on Xiaomi devices.

The Android version is 6.0.1 Marshmallow and the MIUI version is 8.1.2 (stable).

As some of you already know, all Xiaomi smartphones are equipped with the MIUI Rom. The user can choose among some themes and more of them can be downloaded. There are also highly customizable security settings, in example we can easily add our fingerprint. Adding your fingerprint is really easy, just put your finger on the sensor five or six times and the phone will perfectly recognise your fingerprint. The process could seem long but is necessary to obtain a perfect scan of your fingerprint to grant the maximum security to the user.

There are other interesting options into the settings app, for example thanks to the “Second Space” option we can create another user space on the phone exactly like when we add an account on our computer, each user will have his own apps, files and settings. This can be useful if you need to share the device with someone else.

We can do a similar but more restricted operation with the “Dual App” mode. We can duplicate an app to use simultaneously two accounts. In example we can duplicate the Facebook app and use it with with different accounts. The duplicated app will have a special icon, in this way the user is able to distinguish between the “normal” app and the duplicated one.

App Permissions

There is another important aspect into the settings app: permissions. Like all other Android devices the user can customize all permissions that a specific app requests. The MIUI, by default, gives only the minimum permissions required by an app; then it’s up to the user to decide to grant or not another specific permission.

The result is that sometimes a lot of permissions’ requests will be shown and the user will have to enter his decision manually by accepting or denying the request. In this sense, the MIUI is a very restrictive rom but everything is tuned to grant the maximum security for the user.


The preinstalled keyboard is a mix of a standard keyboard and a chinese keyboard. It is quite similar to standard keyboard but sometimes the user could have problems using it because of non-standard options.

On the keyboard in fact you can see at least a couple of buttons with chinese symbols. The standard Google Keyboard that is more intuitive to use. The browsing experience is excellent and does not show any lag. No problem with the pinch-to-zoom. You can notice how good the browsing experience is, no lag and no problems when scrolling the page.


The audio quality is good, especially when used in standard mode (speaker not activated). When the speaker is activated during a phone call the audio is good but not so powerful. The audio quality is good, no distortion problems but when the speaker is activated the phone is simply not so loud.


The Xiaomi Redmi 4 Pro rear camera is 13MP with dual flash led, front camera is 5MP; on the back there is a fingerprint sensor, battery’s capacity is 4100mAh. The display is a 5″ IPS FullHD.

The Xiaomi Redmi 4 Pro rear camera has a 13 MP sensor with a dual flash led. Image quality is very good when there is enough light but it tends to degrade when there is not enough light. So you could have photos with a little bit of noise. The quality is quite good, very good if you consider that this phone is a low range device, it is sold for less than $208.

You could notice a little bit of noise in case of low light conditions and sometimes also the shapes of specific objects could not be well defined, depending on light conditions. No problems concerning contrast and exposure levels, they can also be tuned manually.

In conclusion, the Xiaomi Redmi 4 Pro has a quite good camera easily comparable with other similar smartphones produced by well known brands like Samsung, Sony etc. that have a price a lot higher than this Xiaomi Redmi 4 Pro.

The graphic details are quite good and no lags when playing Real Racing 3, absolutely satisfied by the gaming performance of the Xiaomi Redmi 4 Pro.


The battery is probably the real “shocking” feature of this device, its capacity is 4100mAh so you will need quite a lot of time to charge it from 0 to 100% but the battery life is simply amazing.

This is a really incredible achievement for a 5″ smartphone, even with a heavy usage you will always be able to reach the end of the day without the need of charge the battery. Then you can easily change MIUI’s policy about battery so you can enable all energy-saving feautures or you can disable them to have the maximum performance.

The main aspect of battery management concerns the background activity. By default, in fact, the MIUI tries to limit a lot the background activity so you could have problems with notifications coming from apps like WhatsApp or Telegram but you can disable the background activity restriction to solve the problem.

In conclusion the Xiaomi Redmi 4 Pro is absolutely the best smartphone under $208, this is a real best buy. If you are looking for a smartphone between $177 and $208, then buy it.


There is not any other phone produced by brands like Samsung or Sony that is able to offer this kind of performance and build quality at this price. The build quality, in fact, is a really interesting aspect.

The Chinese smartphones have good hardware specs but a poor build quality, in this case the Xiaomi Redmi 4 Pro is really well built with a proper engineering process and good quality materials. It really seems a high-end device; it is the best smartphone in its category.
