Xiaomi Redmi 4a Review


After a long wait, Xiaomi Redmi 4a finally come to our team for a review. As we said in the preview post, Redmi 4a is one of the best entry-level smartphones on the market right now. The phone impresses from the start with its high quality and stunning performance.Xiaomi Redmi 4a front

The bad things about this this model is the lack of NFC and the entry-level chipset. At the price of just 100$, you will get the same package as Samsung Galaxy J5 or a Sony Xperia E5. In brief, we are dealing with a low-cost alternative of an entry-level phone.


Even if it’s a entry-level phone, Redmi 4a has a quite decent 5-inch 720p panel. Sadly, the display isn’t protected with Gorilla Glass, instead it has some sort of hardened glass that is meant to protect it from scratches.

The display managed to reach the maximum brightness of 475 nits and the contrast ratio of 925. These results are quite better than much more expensive Meizu M5s.

In terms of colors, the phone impresses with DeltaE of 4.5 and a maximum of 7.8. If the brightness is reduced to 200 nits, the display will score an impressive average deltaE of 2.4 and a maximum of 4.8.

The sunlight legibility is quite good as well, the Redmi 4a display reached the sunlight contrast ratio of 2.635, this score is better than the ones reached by phones like Meizu M5s, Xiaomi Mi 4 or Meizu M5 Note.


Xiaomi Redmi 4a comes in a well built plastic unibody design that gives a convincing impression of metal. The phone feels well built and pretty sturdy. On the back is located the main 13 MP camera with Flash LED and near the bottom is a single speaker grille. Sadly, the fingerprint reader is missing on this model.

On the front panel we have an 5 inch 720p display, which is quite scratch-proof even if it doesn’t use Gorilla Glass for protection. Under the display are located three capacitive keys without backlighting. The home button has an integrated notification LED, an unusual position for an entry-level phone.

On the bottom is located the microUSB port with OTG and the main microphone next to it. On the top of the phone is located the 3.5 mm audio jack with a secondary noise-canceling microphone next to it.

On the right side are located the volume rocker and a power button. The opposite side has a micro/microSD and a nano SIM slot.


Xiaomi Redmi 4a runs on Android 6.0.1-based MIUI 8 ROM. The user interface comes with a lot of features to enjoy, it is gorgeous and runs without slow-downs.

For a sub $100 phone, Redmi 4a gives a lot of features, options and granular control over each type of notification with MIUI 8.

That the only bad thing about this model is the lack of performance. Seems that 1.4 GHz Quad Core Qualcomm Snapdragon 425 Processor with Adreno 308 GPU is quite low for stunning Android experience in 2017. On the other hand, 2GB of RAM is more than enough if you are patient with loading times.

If you are planning to buy this model for gaming, you need to know that Redmi 4a struggles quite badly with most modern games, and some of them are not “playable”.

Same as all phones from Redmi 4 series, Redmi 4a comes with a 13 Megapixels (f/2.2 lens) main camera and a 5 Megapixels (f/2.2 lens) front-facing camera.

The first thing we noticed on the main camera was the slow focusing speed and sometimes we often experienced focus hunting. The phone comes with quite interesting modes and filters at its disposal. This camera makes surprisingly good quality photos and the level of detail is pretty high. The sharpness is good near the center and the dynamic range is also quite good.

The 5 Megapixels front-facing camera takes soft and rather low in detail photos.


With a 3,120 mAh battery, Xiaomi Redmi 4a managed to score a 67h on the endurance test. The Snapdragon 425 and the smaller battery makes the difference in this test. We remind you that Redmi 4 Prime scored 91h on the endurance test with a Snapdragon 625 and a 4,100 mAh battery.

At the price of just $100, Xiaomi Redmi 4a is the best choice on the market right now. If you don’t mind the lack of NFC, fingerprint reader and sometimes performance, this is the best choice for you. If you have a bigger budget than $140, we recoomend you Redmi Note 4 or Huawei Honor 5c.

One thing is clear, if you’re short on options or the budget is limited, you can do worse than the Xiaomi Redmi 4a, but you can do better too. The margin of error is pretty slim in the low end devices right now.
