Expert Review

Conclusion:
The Redmi Note 4 is a winner that Xiaomi needs and can be termed as the best device in this price range at least for now. The performance is excellent, so is the battery life. The MIUI on top of Android has evolved a lot over the years, and it not comes bundled with so many customization and amazing features that you can’t stop loving as you keep using. The display quality is amazing too with great color output and excellent viewing angles. It was able to handle every app every game we threw at it with ease. However, on the down side, the camera still needs to get better. It simply fails to live up to the impression left by other departments of the device. So, if you think you are ok with average camera performance, then the Xiaomi Redmi 4 is one such device which won’t let you look for other options in this budget.
Introduction:

Xiaomi; the undisputed king in the budget and mid-range smartphone segment in India. The company has done something incredible the past three years that is still a dream for many brands. The rise from a startup to a well-established company with top-selling models is just phenomenal. The company not just replaced the Indian brands, it also gained immense trust and fans all over the country. Handsets like the Redmi Note 4G, Redmi 1s, Redmi Note 3 were some of the top sellers beating tier one brands like Samsung which was ruling the Indian smartphone market over many years. Xiaomi says this is just beginning and more to come in the future, though we can’t predict the future just yet, for now, it is riding high on success. After successful phones like the Redmi 3, Redmi 3s Prime, Xiaomi is back with the Redmi Note 4 which is the successor to the Note 3. The device has undergone some design changes when compared, and it looks fantastic on paper for starters at least. In our today’s review, let’s see if the Redmi Note 4 will remain as yet another top seller or come as a speed breaker to the success of the brand.

The Xiaomi Redmi Note 4 sports a 5.5-inches Full HD (1920 x 1080 pixels) 2.5D curved glass display, up to 72% NTSC color gamut, 1000:1 contrast ratio. It is powered by the Qualcomm Snapdragon 625 SoC clocked at 2GHz Octa-Core 14nm processor with Adreno 506 GPU coupled with 2GB & 3GB RAM variants with 32GB storage and the high-end model with 4GB RAM with 64GB storage. All these options come with a microSD card slot for memory expansion up to 128GB. It runs on Android 6.0 Marshmallow based on MIUI 8 based.

In the camera department, the device features a 13-megapixel rear camera with PDAF, dual-tone LED Flash, f/2.0 aperture and a 5-megapixel shooter with f/2.0 aperture, 85-degree wide-angle lens on the front for selfies and video calls. The Redmi Note 4 rocks a Fingerprint Sensor and Infrared sensor. Connectivity features include 4G VoLTE, Wi-Fi 802.11 ac, Bluetooth 4.2, GPS + GLONASS. a 4000mAh (minimum) / 4100mAh (typical) battery is on board that promises to give great battery life.

Design & Display:

If you are coming from Redmi Note 3, you will certainly find some similarities in the placements and few design elements. The front panel packs the similar with slim borders on either side of the display with smooth 2.5D curved glass display that looks premium and feels good in hands. The all-metal unibody design is sturdy and compared to previous Xiaomi phones; it is less slippery. However, the rear side is where you find similarities to many phones in the market, and that doesn’t mean we hate what we see here though. There are quite some changes that are subtle and fine refinements that Xiaomi has made are quite evident. The Antenna bands and the Fingerprint sensor combined with camera module placement on the rear panel feels great to look at. Though being a 5.5-inches size, the Redmi Note 4 fits perfectly in hands and one-handed usage is not a problem and design is literally the best we have seen on any Xiaomi phone off late.

The front packs the 5-megapixel selfie camera, primary ear piece, the usual set of sensors, tiny LED indicator, and down below the 5.5-inch display are the three-touch type capacitive buttons that are backlit. The volume rockers and the power button are placed on the right while the left houses the SIM tray. The 3.5mm audio jack, IR blaster, and secondary microphone are present up top and the microUSB port and speaker grills to the bottom. Flipping the device to the rear, you find the 13-megapixel shooter, LED flash, Mi branding, Fingerprint sensor and Antenna bands. Overall, the design is something looks good and feels solid.

The Redmi Note 4 sports a 5.5-inches 1080p Full HD display with a pixel density of 401 PPI. Xiaomi seems to have retained the same panel from the Redmi Note 3, and it is a really good thing because Redmi Note 3 had one of the best panels in this price segment back then. Now even the display of the Redmi Note 4 packs the same punch with colors mostly accurate and perfect viewing angles. Though the color reproduction seems a bit over-saturated, thanks to the customization features, you can change the display modes from the system settings. There is reading mode included which should be comfortable while reading e-books or web-content. Brightness levels are excellent, but they are still reflective which might make accessing the display a bit tougher under broad daylight. At 401 PPI, the text and images look sharp and thanks to the 2.5D curved glass, watching videos or playing games was a pleasant experience.

The company doesn’t say anything about the protected glass, so it is safe if you install a tempered glass or a screen protector to keep it away from scratches and cracks. Overall, the display of the Redmi Note 4 is quite impressive; we just wish the company had taken care of the reflectiveness of the screen.

Performance:

The device is powered by the Qualcomm Snapdragon 625 SoC clocked at 2GHz Octa-Core processor with Adreno 506 GPU. The 625 chipset is one of the best chipset that Qualcomm has ever produced both in terms of performance and power optimization. It could handle our most day-to-day tasks with ease and no issues at all. The Redmi Note 4 was able to run anything we threw at it with ease. The multitasking was butter smooth and if you were to run more than 10-15 apps at a time, only then you might face slight sluggishness in the interface. Apps open up quickly and are even fast to respond as well. Having used the device for more than two weeks, not once instance we faced serious issues nor any heating for that matter.4

Moving to gaming, we ran most intense of titles like the Asphalt 8, Dead Trigger 2, Nova 3, Need for Speed, mortal combat. Playing games was too much fun when graphics render perfectly with no frame drops and with Redmi Note 4 we had just the kind of experience we wished for. Gaming was a pleasant experience with nothing to complain at all. The device also comes with a Fingerprint sensor placed on the rear and it can register up to 5 fingers. Unlocking was pretty fast and it worked 99% of the time accurately. Overall, performance wise too, the Xiaomi Redmi Note 4 stands on top when compared to competition.

Cameras:

The Redmi Note 4 features a 13-megapixel rear camera with LED flash and a 5-megapixel front camera for selfies. Probably the only weakest section of the device and there is no way out with this for now. As like any other phone in this budget, the Redmi Note 4 to clicks decent images as long as you’ve got good lighting. The pictures are good with natural colors and decent details with the refrained balance of color saturation and brightness. The PDAF support allows you to focus on objects even when are on the move quickly. Though at sometimes, images look oversaturated, it can be solved by applying live filters or by taking advantage of the Pro mode.

The camera app is simple with toggles to switch to video mode, front camera mode, flash, HDR mode and more. Swiping from the left gives you access to options like manual mode, panorama mode, and more options. The rear camera can record 1080p videos and the videos looks average at best with dull moments, and the constant hunt for focus makes the video clip annoying.

Moving to the front, there is a 5-megapixel front camera for your selfies and video chats. With good light conditions and outdoors, the camera can click decent images with close to natural colors, but in low-light, it again fails. The pictures clicked in artificial and indoor lighting conditions are full of noise and grainy output. Overall, the camera of the Redmi Note 4 has a lot of scope for improvement, and in low-light, it just fails to live up to the expectations.

Battery:

The Xiaomi Redmi Note series is all about the incredible battery life. Following the same suite is the Redmi Note 4 which comes with a massive 4000mAh battery. The large battery unit is more than capable to last one and half day even with moderate to heavy usage. As for light casual users, they won’t have issues stretching the battery life for two days straight. We did our testing with either 4G or Wi-Fi enabled all the time and never had to enable any power saving modes to save juice. There is no stand-by drain as well, so you have nothing to worry even if you leave the phone idle for a long time.

The only drawback is its lack of fast charge support. The bundled adapter isn’t a fast charger, and hence the device takes good two hours’ time to charge completely from 1-100%. It would have been so much better had the company included Quick charge 3.0 which the chipset supports.

Audio & Video:

The Xiaomi Redmi Note 4 comes with a 3.5 mm audio jack which is present on top, and the speaker grills are present on the bottom. The device comes with audio presets which you can tinker around and also it gives you an option to select the earphones that you are using and syncs with it. The sound output via the headphone is decent without any distortion, and the bass levels are good too. The loudspeakers are placed on the button, and their performance is excellent. The speaker is loud enough to spread in an entire day, and we never missed any call or notifications.

Video department excels with 1080p playback even with default video player. It had no issues at all pulling Full HD videos in all formats without any heating or freezing issues. There are no audio profiles to change, so you are stuck with default presents, and it is a good thing unless you are looking for something out of the box. Overall, audio and video department too doesn’t disappoint.

Software & Ui:

The device has got the Android 7.0 Nougat update with MIUI 8 on top. Xiaomi has gained their immense fan base, especially in India even before its launch is because of their MIUI interface. The interface resembles iPhone style with all the apps, widgets, shortcuts present on the home screen itself. There is support for tons of themes and wallpapers which can change the look and feel of the U.I with just one tap. Another good thing about MIUI is that the community support is immensely active and is growing at a rapid face every passing day. The animations, transitions are sleek and are butter smooth; we particularly liked the animation while uninstalling an app. The new gallery app automatically syncs photos to Mi cloud where you get around 5GB free space.

The MIUI 8 has a special Quick Ball feature which always stays on the home screen with shortcuts like lock screen, multitasking menu, back button and more. The dual app feature lets you run all the supported apps in two instances like for example you can run two WhatsApp accounts on the same phone. Another impressive addition to the software is the Second space; this creates a fresh new space which differentiates work and personal data. It also lets you use two different Google accounts. The scrolling screenshot feature allows you to capture long screenshots by just scrolling further down. There is also a one-handed mode where the screen shrinks allowing users with small hands to access quickly.  Though all features are useful and come in handy some way, we feel that the default pre-loaded apps count is way too much and Xiaomi should cut down to some extent.

The Redmi Note 4 is available in 3GB RAM model and 4GB RAM variant. If you were to pick the device, we’d suggest you go with the 4GB model which gives more room for better performance. For casual day-to-day usage, you would never notice any lags or hiccups with animations or general U.I transition either. We had more than 5-6 apps running in the background most of the time and even still we never noticed any significant stutters. However, occasionally few apps used to reload for running out of memory, and this wasn’t a big deal for us anyway. Overall, despite the heavily themed interface, the Redmi Note 4 still managed to pull through.
