We review the Redmi 4 Prime!


While we were busy reviewing our Mi Mix, an unexpected item got launched by Xiaomi, and its the successor of the successful Redmi 3S. Introducing the all new Redmi 4! This series has 3 variants, Redmi 4 Basic, Redmi 4 Prime and Redmi 4A. We are going to review them one by one and lets focus ourselves on the Redmi 4 Prime.






Normally Xiaomi units gets launched within a year but seems Xiaomi has been stepping up the pedal recently and launch their items so fast that we had a hard time catching up with the releases. Redmi 3 got launched January 2016, Redmi 3s last June 2016, and now Redmi 4 November 2016. It took just roughly 5 months for the Chinese Smartphone manufacturer to launch another variant of the budget friendly Redmi Series.

Whats in the Box:







Powerful yet Pocket Friendly
Now we have notice the side by side specs of the Redmi 4 Prime is not the same as the Redmi 4 Basic especially on the SoC department. The overall apperance is the same except for the placement of the LED flash, camera and the fingerprint scanner. The Redmi 4 series sports a more edgy corner compared to the Redmi 3 series which is more rounded. The metal body of the Redmi 4 looks elegant and slim, but we feel its a little thicker than the Redmi 3S (Redmi 3S 8.5mm, Redmi 4 8.9mm) based on our hand experience we were able to directly say it was a little thicker than its predecessor without using the caliper yet.









The Redmi 4 sports more cornered edges design and but has gentle sloping sides to make sure its easy to grip on the hands.






The top of the phone shows the 3.5mm audio jack as well as the IR blaster and the noise-cancellation mic. While at the bottom we can find the Micro USB port, we were surprised with the placement of the loudspeaker which is already located at the bottom of the phone, no longer at the back of the phone which hinders us from hearing the call notification alert when the back is lying flat on the table. It looks like Xiaomi did listen to its customers and revamped the Redmi 4 design. The right sports the Volume Rocker and powerbutton while the left sports the sim card trey.







The phone is pretty easy to carry, being the 5 inches smartphone that it is, this is the perfect size for one handed use. The HD display is good enough as a daily driver and it is equipped with the sunlight display technology which is a big advantage when using the phone under the beam of the sun. The capacitive button does not lit up like the MI Series, but the notification light can be found beside the earpiece on the left, it used to be below the capacitive home button.





There is a slight difference in term of design for the Redmi 4 Basic and Redmi 4 Prime, and you can notice that the LED flash placement of the Basic is at the right of the camera while the Prime will be located at the left of the camera. Plus the placement of the Fingerpint Sensor and Camera is not identical as well. You have to be careful in buying protective cases because Redmi 4 Basic and Redmi 4 Prime is not identical in terms of LED, Camera and Fingerprint Scanner placement. Redmi 4 Prime sports a dual LED flash while Redmi 4 Basic has a single LED flash.

This model has the latest MIUI 8.0 installed and sporting Android Marshmallow 6.0.1, bootloader is locked therefore you have to checkout en.miui.com/unlock to flash your favorite custom rom should you require in the future.





Snapdragon 625 Powerful Daily Driver
Redmi 4 Prime sports the Snapdragon 625 which is more powerful and faster than the Snapdragon 430 inside the Redmi 4 Basic. This SoC supports fast LTE connection in CAT 7. We were able to do task with a breeze, like multitasking and play some online games. Its performance for multitasking is above average but of course cannot be compared to the Snapdrgon 8-series SoC. AnTuTu gave it a 61,494 points. For more detailed infomation on the processor, check this out: qualcomm.com/products/snapdragon/processors/625








Audio and Video:
We have tested the audio for the loudspeaker, it is pretty normal for a small phone of its size, nothing special about it, comparing to the Redmi 4 Basic, its at par, nothing different. We also tested watching 720p video via youtube and its pretty clear and crisp. The displays is better than the Redmi 4 Basic since it sported a Full HD display. Good job on that category for Redmi 4 Prime.

Decent Camera
The camera used in this series we believe is not the same as the Redmi 3S which we claimed to have a little difficulty in focusing and takes a little while to focus. This time Redmi 4 turn it around and probably equipped a better sensor, from what we heard is a Samsung Sensor but we have yet to confirm it yet. Camera is pretty decent for its price range and we were able to get some good snaps under good lighting and a bit disappointing under low light, but for a budget series, we cant complain much right?

Good Endurance Battery!


One of the main focus that we have notice from this unit, othert than its pocket friendly price, is its battery. We were able to let PC Mark do the battery stress test for us and after the long endurance test, it yielded a whooping 13 hour 13 minutes . This is what we all want, a long lasting battery, since the SoC consume less power, battery life should be longer.

Mitch002 Verdict: Good Processor, Excellent Battery



With Xiaomi releasing so many Redmi 4 series all at once this time, its debateable which one will take command in terms of sales. But definitely for us its the Redmi 4 Prime, packed with more firepower at the same time it has a pretty decent camera for an average point and shoot user. This is pretty good for people on the go who uses minimal mobile data, just purely calls, text and some surfing from time to time. You dont need to frequently hit the powersource and the powerbank, it should last you for 1 whole day without a sweat. Overall the Redmi 4 Prime is easy to hold, have an above average performance, decent camera and extra long battery life. We recommend this unit more than the Redmi 4 Basic, but if you are more on a tight budget, you can opt for the Redmi 4 Basic which is 200 RMB cheaper than the Prime.


The 2GB Ram 16GB Storage is available for 699 RMB while the 3GB Ram and 32GB Storage is available for 899RMB on Xiaomi China Website.
