Asus Zenfone 3 Deluxe Review – A missed opportunity due to weak battery life and exorbitant price

Asus Zenfone 3 Deluxe Review

Back in May last year, ASUS unveiled the Zenfone 3 family at Computex which made its way to India after a couple of months. The Asus Zenfone 3 series features the Zenfone 3 as the main variant, Zenfone 3 Ultra as a high-end phablet and the Zenfone 3 Deluxe as their top of the line smartphone. The Zenfone 3 Deluxe is Asus’ 2016 flagship sporting powerful hardware innards and a premium design language, that competes with a series of flagships like iPhone, Galaxy S7 series and Google Pixel. The Deluxe edition stands out with an all-metal design which Asus touts as the world’s first smartphone with an invisible antenna design. On top of that, it flaunts a sleek form-factor, Super AMOLED display, and a powerful performance backed with 6GB of RAM.

Today, we’ll be reviewing the budget variant of Deluxe with Snapdragon 820 on board. Meanwhile, there is another top-end model of Deluxe featuring a massive 256GB of storage and Snapdragon 821 processor. Now let’s find out how the device fares against the stiff competition and if it’s a worthy offering or not?

Build and Design

The Zenfone 3 Deluxe has come a long way in terms of design and overall build quality as compared to its predecessor, Zenfone 2 Deluxe. Being a flagship phone, the device features a real full-metal unibody design, unlike the metal and glass construction as seen on its mid-range siblings. Despite sporting a 5.7″ display, the phone looks fairly compact and is surprisingly lightweight, thanks to the use of a light aluminium alloy that is sturdy too. The main design highlight is the “invisible antenna design” which you won’t find on most smartphones. What’s impressive is that there are no side bezels on the front whereas the top and bottom bezels are fused with Asus’ iconic concentric circle pattern. There are rounded corners, chamfered edges on the front and back, and the back portion is seamless with gentle curves that make it comfortable to hold. The smooth matte finish across the sides and back feels premium and doesn’t attract fingerprints or smudges.

The Deluxe is super sleek at the edges at just 4.2mm and 7.5mm at its thickest point. Weighing at 170 grammes, we never found it uneasy to hold even during prolonged usage. The phone comes with backlit capacitive keys which oddly aren’t center aligned horizontally and there is a notification LED on the top. The power and volume rocker on the right side are made of metal and offer a good tactile feedback. Asus has retained the 3.5mm audio jack which is on the top and used Type-C port for charging which sits at the bottom along with the speaker grille. The left side houses the Hybrid SIM tray and secondary mic.

Moving to the back, there is a square-shaped camera which is slightly protruding but comes with Sapphire glass protection to withstand scratches. Right below the rear camera, you’ll find the rectangular Fingerprint scanner followed by a neatly embossed Asus branding at the lower bottom.

Overall, the Zenfone 3 Deluxe boasts a minimalistic but elegant design that doesn’t feel chunky to hold or carry around.


Asus Zenfone 3 Deluxe Super AMOLED display

The Zenfone 3 Deluxe sports a 5.7″ Full HD Super AMOLED display having a 1920 x 1080 resolution at 386ppi. There is Gorilla Glass 4 protection on top. Considering the premium pricing and bigger screen, a Quad HD display would’ve been great but the 1080p panel offers an impressive viewing experience altogether. The display with high contrast ratio looks very bright, crisp, and has excellent viewing angles. As expected from a Super AMOLED display, you get vivid colours, deep blacks and a high colour saturation when ‘Super color’ mode is enabled. The gorgeous and punchy display is a visual treat while playing games and watching movies. Moreover, Asus has included a Splendid app to customise the colour temperature as desired that lets you manually adjust the hue and saturation too. We loved using the device in Super Color mode, though. The touch feels quick and responsive.


Talking of the software, the Zenfone 3 Deluxe runs on Android 6.0.1 Marshmallow with Asus’ custom ZenUI 3.0 on top. After receiving the review unit, we immediately got the OTA update for Android 7.0 Nougat with December security patch. Those unfamiliar about ZenUI, it offers a lot of features and customization options but at the same time packs much bloatware like duplicate and pre-loaded apps. The heavily skinned UI on Asus phones is something which users might like or hate, depending on their usage.

With Nougat on board, the Deluxe gets bundled notifications, split-screen mode, quick app switching via multitasking key, adjust display size and a new settings app. While comparing the Deluxe edition with Zenfone 3, we noticed an additional OptiFlex option in settings that lets you speed up launch performance of selected apps. Also, there is an Always-on Panel that displays a clock in standby mode, similar to Moto Display but we didn’t like its UI. Despite running the latest Android version, there are still few outdated UI elements like the Widgets section in the app drawer and those spherical Quick Settings toggles still exist.

Similar to other UIs, there are pre-installed apps like Amazon Kindle, Facebook, Instagram, Messenger, Puffin, and Trip Advisor. Besides having a feature packed Theme store, the ZenUI offers a host of software features such as the ability to lock apps, single-hand mode, changing icons packs, Kids mode and likes. Also, there are some useful apps from Asus such as Game Genie, Mini Movie, Photo Collage, and Mobile Manager. ZenMotion is another useful feature that includes gestures like double-tap or swipe up to wake, draw gestures to launch apps, and flip the device to mute.

Overall, the UI elements look good but the excessive bloatware feels unnecessary at times and could disappoint users who prefer a Stock Android experience.


Powering the Zenfone 3 Deluxe is a Quad-core Snapdragon 820 processor clocked at 2.15GHz with Adreno 530 GPU. This is coupled with a whopping 6GB of RAM and 64GB of storage that is expandable up to 128GB via microSD card. The powerful package inside delivers an absolutely solid and butter smooth performance, both in terms of heavy multitasking as well as intense gaming. As expected, there was no instance when the device struggled or tend to lag while performing everyday tasks like switching between apps, web browsing, accessing social media apps and a lot more. The Deluxe delivers a very fluid experience despite packing a heavily skinned ZenUI and even when there were numerous apps opened in the background, including some games.

In terms of gaming, the device scores well without any issues. We never noticed any frame drops or occasional stutters while playing graphic intensive titles like Nova 3, Dead Effect 2, and Asphalt 8. There are no severe heating issues whatsoever. Talking of the synthetic benchmark tests, the device scored 151377 points in AnTuTu whereas, in Geekbench’s 4 single-core and multi-core test, it scored 1653 and 3854 points respectively.

Connectivity options include 4G LTE with support for Reliance Jio VoLTE, Wi-Fi 802.11a/b/g/n/ac with 2×2 MIMO support, Bluetooth 4.2, GPS, USB OTG and FM Radio. It should be noted that you can’t use dual SIMs and microSD card simultaneously due to the presence of a Hybrid SIM card tray. The phone is rich in sensor department but lacks an Infrared sensor.

The recessed Fingerprint sensor at the back is fairly easy to reach and high in accuracy. But it’s not the fastest sensor as often we noticed a delay of few seconds while unlocking the phone. Moreover, there is no haptic feedback when you tap on the scanner. The fingerprint sensor can be further used to answer incoming calls, launch camera app and capture photos. There is no option to lock and unlock specific apps using the sensor, though.


Asus Zenfone 3 Deluxe 23MP camera

The Zenfone 3 Deluxe comes with a 23MP primary camera with f/2.0 aperture, 4-axis optical image stabilization (OIS), laser and phase detection autofocus system. It also packs a Dual-LED real tone flash and RGB sensor for colour correction. The front shooter is an 8MP one with the same aperture and wide-angle lens. The typical ZenUI camera app is feature rich and offers a plenty of shooting modes such as HDR Pro, Beautification, Super resolution, Low light, Depth of field, Time lapse and much more. Additionally, there is a powerful “Manual mode” that shows real-time values for ISO, shutter speed, exposure and a live histogram too apart from the regular controls to adjust the values manually.

All of the camera tech sounds great on paper but let’s see how it performs in real life usage. The 23MP shooter captures a lot of details in daylight conditions, making the shots look very good and crisp with good colour reproduction. In well-lit indoors, the photos captured looked really good with accurate colours but the details do take a hit and some digital noise also creeps in. The Deluxe does a good job even in low-light conditions, as the images came out bright and clear with a decent amount of details but exhibited moderate to high noise, depending on the lighting. However, the shutter can be pretty slow in darker areas that often results in blurry night shots despite the inclusion of OIS.

Speaking of the 8MP front camera, it does a great job in almost all lighting conditions including indoors. The selfies captured in different scenarios (with beauty mode disabled) turned out very good with ample of details and right colours. Nothing to complain about it. It also packs most of the main camera modes like Beautification, HDR Pro, Night mode, Slow motion, and Time lapse.

That said, the overall camera performance is rather impressive but it’s clearly not on the lines of Galaxy S7 edge and iPhone 7.

The Zenfone 3 Deluxe offers a rich multimedia experience with its vivid display and good audio quality. The handset is equipped with a single 5-magnet speaker with NXP smart amp technology and supports high-resolution audio through the 3.5mm audio jack. The speaker is loud enough plus the overall sound quality is good, except for little distortion at high volume. The bundled “ZenEar S” earphones with an aerospace metal casing and support for Hi-res audio, sound pretty good and are comfortable too. There is an AudioWizard app in sound settings that lets you fine tune the equalizer and manually setup sound profiles for movie, music, gaming and vocal.


The Zenfone 3 Deluxe comes with a 3000mAh battery but it failed to meet our expectations. Despite packing a Full HD display, the phone delivers a below average battery life which is pretty disappointing. We noticed the battery level dropping down quickly especially during heavy gaming. Under light usage, the device is able to last through the day whereas, under normal to slightly heavy usage pattern the battery drains faster than expected, offering a screen-on time of just 2-3 hours. For some reason, there is a rapid battery drain when the device is idle and during overnight when it lost 8 percent of charge and powered down. As compared to our Zenfone 3 (ZE552KL) that offers a superb battery life, the battery on Deluxe is nowhere close.

Fortunately, the Deluxe supports QuickCharge 3.0 that charges it really fast and the supplied 18W charger can fully charge the device in around 80 minutes. We recommend sticking to ‘Normal mode’ to get a better backup. Additionally, Asus has included some smart battery saving modes like Power saving and Super saving that one can use to increase the battery life.


The Asus Zenfone 3 Deluxe variant we’ve reviewed is priced in India at Rs. 49,999 whereas the special edition is priced at Rs. 62,999. The Zenfone 3 Deluxe comes off as a pricey phone especially in India when compared with its US pricing, where the unlocked Snapdragon 820 variant retails for $500. This converts to around 33K which is a reasonable price tag but somehow Asus chose to price it very high here in India.

Although the Deluxe edition impressed us with its all-aluminium build, gorgeous display, a powerful performance and good cameras but there are a few shortcomings too, the main being the weak battery life. In a similar or lower price range, there are some good contenders like Samsung Galaxy S7 edge, OnePlus 3T, Moto Z, Google Pixel and iPhone 7. While the Pixel and iPhone have an edge in terms of camera, the OnePlus 3T and Moto Z are more affordable choices that offer the best value for money. That said, it’s tough to recommend Zenfone 3 Deluxe at this price tag but one can consider checking Asus’ own Zenfone 3 base variant that we’ve reviewed earlier, which is a good option in sub-30k price segment.
