Xiaomi Redmi 3S Prime GreyIf you're looking for modern features and a low price tag then the Redmi 3S Prime from Xiaomi is a great choice.

The 5" HD screen and seamless aluminium frame let the phone sit comfortably next to competitors' devices which may cost more than twice the price.

The bright display is perfect for streaming videos, browsing the web and playing games. There is also a built-in universal remote control thanks to the Infrared blaster, enhanced audio for music lovers and high-end wireless connectivity options.


Xiaomi's Redmi 3S Prime is manufactured with a sleek aluminium frame and thin 8.5mm profile.

Despite a huge 4,100 mAh battery, the phone is still only 144 grams in weight. New high density battery cell technology allows for the increase in capacity without compromising space.

The Redmi 3S Prime's glass goes right to the edge of the thin bezels, cutting a slick form. Xiaomi have also introduced touch sensitive buttons onto the bottom bezel, increasing the usable space of the screen interface.

A standard micro USB port sits on the base of the phone. Power and volume buttons are on the right edge, with a 3.5mm audio jack and Infrared blaster on the top.

On the rear of the phone the camera sits flush with no bump and there are 120 precision drilled holes for the speaker. Just above these is an almost imperceptible 1mm fulcrum that stops the phone from sliding on slick surfaces.


Xiaomi Redmi 3S Prime Control ButtonsThis version of the Redmi 3S Prime is powered by a Qualcomm 430 Snapdragon processor and 3GB of RAM. The added 1GB of RAM on the Prime version goes a long way to increasing speed.

As a 1.4GHz Octa(8)Core system, this is a fairly middle of the road processor. It is, however, still capable of offering a great compromise between performance, efficiency and and affordability.

This is really key to the appeal of the 3S Prime. The phone is still more than able to handle anything the average smartphone user is likely to do. By utilising a lower power processor, the battery life is also further extended.


Having a decent camera can increase a phone's desirability several notches. Xiaomi know this and ensure that even their budget devices can take excellent images.

The 13MP main camera has a fairly high resolution and is coupled with more impressive technology to improve picture quality.

A 5-element lens with ƒ/2.0 aperture is designed to let in a generous amount of light. Modern Phase Detection Autofocus (PDAF) is also provided for high speed focussing - perfect for taking detailed images without spending forever lining them up.

Other features include a two-tone LED flash, enhancements for taking pictures in low light, HDR, Panorama, Burst and Real-time filters.

At 5 megapixels, the selfie camera is a good resolution and benefits from a large ƒ/2.0 aperture for increased light capture.

12 real time filters enable you to personalise pictures before taking them, plus there are a bunch of additional after effects available too.


Xiaomi Redmi 3S Prime Dual SIMThe 4,100 mAh battery installed in the Redmi 3S Prime delivers an incredible lifespan. This is around 30-40% larger than other leading Android brands with similar screen sizes and processors. Even heavy users should see them getting well into a second day.

The battery is non removable and compatible with micro USB chargers up to 2A.

Xiaomi MIUI

Xiaomi have also installed their own MIUI skinned version of Android 6.0.

This includes system applications such as Phone, Messages, Email and Calculator that have been thoroughly redeveloped over the the original Android apps. This improves performance as the system apps are tailored to each Xiaomi phone.

A powerful Themes engine is also available so you can personalise ther phone's look. With all of the system apps being deeply integrated with MIUI, when you change Theme, everything can get reskinned, not just the wallpapers and icon packs.

The Xiaomi phone has an Infrared blaster so you can take advantage of the Xiaomi Universal Remote application. Thousands of manufacturers, brands and applications are supported.

Several backup options are available in today's digital world Xiaomi Mi Cloud though provides a system which works across all Xiaomi devices and can be accessed independently through any web browser.
