Xiaomi Redmi 3S – Overview Price Specifications

Xiaomi is a privately owned electronics company that opened in April of 2010, and is based in Beijing, China. In January 2016 Xiaomi released the Redmi 3 smartphone. Unfortunately, in today’s competitive market it didn’t last very long, so Xiaomi was forced to step up their game. They did just that, and in June 2016 they released the updated version called, Redmi 3S.

The Redmi 3S isn’t the most powerful device Xiaomi has ever released, but it does have all the specifications you’d want while still being an affordable device. It also has a built in fingerprint scanner, which would make it the first 5 inch MIUI smartphone to do so. The true question is, how does the Redmi 3S stack up against other, well known, cell phones?

For this test I have decided to compare the Xiaomi Redmi 3S to the top selling cell phone of 2016, the Samsung Galaxy S7 Edge. The first thing people look for and/or want in a cell phone is size and appearance.


Dimensions: The Redmi 3S is 139.3mm X 69.6mm X 8.5mm while the Galaxy S7 Edge is 142.4mm X 69.6mm X 7.9mm. As you can see the Redmi 3S is only 3.1mm shorter than the Galaxy S7 Edge, and both phones are the same width; however, the Galaxy S7 Edge is .6mm thinner than the Redmi 3S. The desire for bigger and thinner phones makes the Galaxy S7 Edge the better choice here, but there are some who still want the sturdier feel of a bigger phone.

Weight: The Redmi 3S is actually lighter than the Galaxy S7 Edge weighing in at 144g while the Galaxy S7 Edge is 157g. Most people today carry their cellphones in their pocket or in their purse so weight is something to strongly consider when choosing a new phone. In the weight category I’d have to say the Redmi 3S is the better choice.

As far as visual is concerned I would say the Redmi 3S held up pretty nice against the Galaxy S7 Edge. It will all depend on your individual wants and needs as to whether the smaller but lighter Redmi 3S is better than the bigger, but heavier, Galaxy S7 Edge.

One of the next things people demand from their phone is operation. Whether you want to play games all day, watch videos, or simply text and make phone calls, we all want a phone that will perform at the best level possible. Most people also don’t have access to a phone charger all the time, so battery life is an absolute must as well. I have continued to set the Redmi 3S against the top selling cellphone, the Samsung Galaxy S7 Edge, for this test too.


Operating System: Both the Redmi 3S and the Galaxy S7 Edge operate with Android v6.0.1 (Marshmallow) operating system so there is no difference in the two phones on that level.

CPU: The Redmi 3S has the Octa-Core 1.4 Ghz Cortex-A53 while the Galaxy S7 Edge has an Exynos 8890. Several different tests have been done on these two CPU chips, as well as other CPU chips, and the results were surprising. The Galaxy S7 Edge took top scores in most of the test, but the Redmi 3S chip wasn’t very far behind it. Once again it will come down to your individual needs as to which one will perform better for you.

Ram: The ram on a platform determines how many programs you can run at one time, so if you plan on moderate use then the Redmi 3S would be sufficient for you as it only has 2GB ram. The Galaxy S7 Edge on the other hand has 4GB ram so it will be able to handle a much heavier work load. It will all depend on how much you plan to use it as to which one would be a better fit for your needs.

Storage: Storage is always the main complaint people have with phones, but since both these phones can take an SD memory card up to 256GB storage shouldn’t be an issue. The main difference between the Redmi 3S and the Galaxy S7 Edge here is that the Redmi 3S only has 16GB internal storage while the Galaxy S7 Edge has 32/64GB internal storage, depending on which one you get. For those that don’t wish to buy an expandable memory card, the Galaxy S7 Edge is the better choice.

Battery: Most people prefer a phone that will last all day as most don’t typically have a charger on them at all times. In this regard the Galaxy S7 Edge falls short to the Redmi 3S as the Galaxy S7 Edge only has a 3600 mAh battery and the Redmi 3S has a 4100mAh battery. Bigger battery means more time spent talking or gaming and less time looking for a charger.

Another key selling point is the display of phone. Brighter and clearer is always better. Is the screen big enough to see everything easily? How well can you see the screen outside? Are the colors bright and crisp? All these are questions to ask when comparing phones.


Resolution: This is one place where the Redmi 3S falls way short of the Galaxy S7 Edge, as the resolution on the Redmi 3S is 720 X 1280 pixels. The Galaxy S7 Edge has double the resolution at 1440 X 2560 pixels, meaning it will have a sharper and clearer picture than the Redmi 3S. Both phones do however have an ambient light sensor that automatically adjusts the screens lighting depending on the brightness of the area you are in.

Size: The Redmi 3S has a 5-inch screen while the Galaxy S7 Edge has a 5.1-inch screen. Not much of a difference but again it falls back on your personal preferences. If you wish to carry the phone in your pocket, then the slightly smaller screen on the Redmi 3S would be more useful.

Camera: The Redmi 3S has a 13MP primary, (rear facing), camera with phase detection auto focus that will take a nice picture in most settings. It also has a 5MP secondary, (front facing), camera for taking that perfect selfie or a crisp clear video chat. The secondary camera on the Galaxy S7 Edge is 5MP as well so there is no difference in the two phones there. The Galaxy S7 Edge though only has a 12MP primary camera, but it also has dual pixel technology and the fastest auto focus of any phone allowing it to take crystal clear pictures, even in low light areas.

Along with all the aforementioned things, there are also things that the Redmi 3S possesses that most other cell phones do too. There may be slight differences in exact specifications but for most part all are equal to each other in following areas.


Alert Types: There are three different ways to be alerted by the phone, vibration, MP3, and WAV ringtone. Vibration setting will do just that and only vibrate to notify you. No sound will be emitted. MP3 and WAV ringtones allow you to use music or sound clips for ringtones. You will be able to take a section of your favorite song, or maybe a clip from a funny movie, and apply them as ringtones.

Loudspeaker: The Redmi 3S comes equipped with a loud speaker so you can listen to music without headphones, or use the speaker phone on the phone.

3.5mm jack: The Redmi 3S also comes equipped with a 3.5mm jack for use with headphones for when you’re in a crowed place. (Also has active noise cancellation with dedicated mic)


WLAN: Wi-Fi 802.11 b/g/n, Wi-Fi direct, and hotspot are all active communication options with the Redmi 3S.

Bluetooth: There are two Bluetooth options with the Redmi 3S. They are v4.1 and A2DP.

GPS: The Redmi 3S has GPS capabilities and supports three different kinds. A-GPS, GLONASS, and BDS

Infrared Port: The Redmi 3S comes with an infrared port that can be used for remote control apps. Infrared is a wireless technology that can link two different devices together wirelessly as long as there’s a direct line of sight between the two objects. It is most commonly used with TV remote control apps so people can control every device with one remote.

Radio: There is also a built in FM radio on the Redmi 3S so you’ll always be able to have music to listen to.


Finger Print Scanner: Some of the Redmi 3S have built in fingerprint scanners. The 32GB version made in India has no fingerprint scanner but the 16GB versions made in China do have them. The fingerprint scanner is most typically used to put a personal lock on the screen as only the owner will be able to unlock the phone.

Sensors: The Redmi 3S comes equipped with a variety of sensors built into it, like an accelerometer, gyro, proximity, compass, and ambient light. The accelerometer and compass can be used for mapping routes and/or geocaching. The proximity sensors primary use is to detect when your ear is near the phone so it can turn off the backlight. Turning off the back light will help conserve the battery and help avoid inadvertent touching of the screen with your cheek. Ambient light sensor will adjust the brightness of the screen depending on the light you’re in, thus saving the battery and making screen easier to see.

Messaging: SMS (thread view), MMS, email, push mail, and IM messages are all supported on the Redmi 3S.

Browser: HTML 5 supported

Supported Files: Multi Touch, DivX, Xvid, MP4, MP3, WAV, eAAC+, FLAC player, photo/video editor, and document viewer; Does not support Java

Dual Sim: Micro sim, nano sim, and dual stand by. You can run the Redmi 3S with dual sim cards or use one sim card and put an SD memory card in the slot the second sim card goes in.

All in all, the Redmi 3S made by Xiaomi seems to be a pretty solid choice of phone. I just compared all important parts and/or functions of the Redmi 3S to the top selling cell phone of 2016, the Samsung Galaxy S7 Edge, and the Redmi 3S held its own in my opinion. The screen was lacking in pixel quality compared to the Galaxy S7 Edge but the battery was better. All other tests were very close so ultimately it will boil down to the consumer and what their individual needs are.

Something else to consider is that the Samsung Galaxy S7 Edge starts at $550 while the Xiaomi Redmi 3S starts at $120. Is the extra $400 really worth it? I guess that depends on the work load that you plan on putting on the phone. For the money though the Redmi 3S seems like it will perform almost as well, in most categories, as the more expensive ones do.

If you are looking for a good quality phone, with good reviews, and not looking to go broke buying it, then look no further than the Xiaomi Redmi 3S. There are hundreds of phones you could compare with, but I chose the top selling Samsung Galaxy S7 Edge to show that this Redmi 3S can compete with even the best of them without costing you an arm and a leg. The Redmi 3S can be bought for a fraction of what other phones cost, and the Redmi 3S also comes in Gold, Silver and Dark Grey.
