The Samsung Galaxy S9 Review : Galaxy S8 Perfected!

When pictures of the Samsung Galaxy S9 first leaked, pundits criticised how similar it looked to its predecessor – the Samsung Galaxy S8. But the familiar facade hides a number of important upgrades. Find out why we think the new Samsung Galaxy S9 is the perfected Galaxy S8!

 

The Samsung Galaxy S9 & Galaxy S9+

Like the Samsung Galaxy S8, there will be two sizes – the Galaxy S9 (SM-960) with a 5.8″ display, and the larger Galaxy S9+ (SM-965) with a 6.2″ display. Here is a table comparing their specifications :

This time around, Samsung made more of an effort to differentiate the two models. The larger Galaxy S9+ not only comes with a larger battery, it also has more memory and storage options, as well as a dual camera system.

The Samsung Galaxy S9 Colour Options

Samsung is making the Galaxy S9 (Price Check) available in four colour options – Midnight Black, Coral Blue, Lilac Purple, and Titanium Silver. However, not all of them will be available worldwide.

In Malaysia, only these three colours are available (at least initially) – Midnight Black, Coral Blue, and Lilac Purple.

The Samsung Galaxy S9 Up Close

The Samsung Galaxy S9 (Price Check) is very similar to the Samsung Galaxy S8 in design. They both boast the same glass and metal design, with an Infinity Display and IP68 dust- and water-resistance.

In most countries, the Samsung Galaxy S9 (Price Check) is powered by the Samsung Exynos 9810, while in the US, it runs on the Qualcomm Snapdragon 845. It comes with 4 GB of LPDDR4x memory, and 64 GB of storage (with a 128 GB option in some countries).

Despite rumours that Samsung would be ditching the dedicated Bixby button and 3.5 mm earphone port, they will both still here.

 

The Front Camera

The Samsung Galaxy S9 (Price Check) retains the Galaxy S8‘s front camera with the 8 MP Samsung S5K3H1 sensor and an f/1.7 lens. It is capable of recording 4K videos at 30 fps, and has great low-light capability.

Its low-light capability will come in handy, as the front camera does not have flash support, not even screen flash.

 

Dual Aperture Camera

The Samsung Galaxy S9 (Price Check) boasts a new dual aperture camera, that was first used in the rare and expensive Samsung W2018 smartphone (available only in China).

This dual aperture camera has a mechanical aperture that lets you switch between an incredibly bright f/1.5 aperture, and the f/2.4 aperture for a deeper depth of field.

The f/1.5 aperture is the widest aperture so far in a smartphone, offering just over ⅓ stop more light than the f/1.7 aperture of the Samsung Galaxy S8‘s camera. This translates into better low-light photography with less noise.

[adrotate group=”1″]

 

New Samsung ISOCELL Fast Sensor

Samsung also used their latest ISOCELL Fast SAK2L3 sensor in the new cameras. This is a 12 MP sensor with large 1.4 µm pixels for excellent low-light performance.

The Fast designation means it comes with its Dual Pixel and Super PD capabilities. It also boasts a 3-stack FRS (Fast Readout Sensor) that allows high-speed captures of Full HD video.

The Dual Pixel technology is an autofocus technology that uses the dual photodiodes in every pixel on the image sensor for phase-detection autofocus. This allows for faster and more accurate focusing, because it uses many more autofocus pixels, instead of just a few dedicated pixels (usually less than 5% of the total).

 

Super Slow-Mo

The Samsung Galaxy S9 (Price Check) supports a new Super Slow-mo feature, which allows you to record 720p video at 960 fps.

The Super Slow-mo videos can be instantly edited, with a random selection from preloaded choices. Or you can use your own music / songs. You can also create a GIF from the recorded video, with three style of looping – reverse, forward or swing.

The new ISOCELL Fast sensor, when paired with the Samsung Exynos 9810, is said to be fast enough to record slow-motion 1080p video at 960 fps / 4K video at 120 fps. However, the Qualcomm Snapdragon 845 is not fast enough, so Samsung limited Super Slow-mo capability to ensure consistent experience worldwide.

There are other caveats too – Super Slow-mo is limited to 20 shots per video, with approximately 0.2 seconds of recording and 6 seconds of playback for each Super Slow-mo shot.

Bixby Live Translation

The original Samsung Bixby is capable of live translation, so a more accurate description of this new feature is AR (augmented reality) Translation.

In the original Bixby, the translation appears as a separate card. But in the new Samsung Galaxy S9 Bixby implementation, the translation appears as part of the image. Hence, our opinion that it should be called AR Translation.

In fact, it is smart enough to take note of the font and background of the text being translated, and render the translation as if it was the original text!

This is, without doubt, a truly useful combination of Bixby and augmented reality!

 

AR Emoji

This is arguably one of the coolest software features in the new Samsung Galaxy S9 camera system. You can use either the front or rear camera to take a picture of anyone, to create augmented reality emojis that look like your subject!

The Samsung Galaxy S9 (Price Check) will automatically create an avatar that looks like you, which you can customise to your satisfaction. They will also automatically create 18 stickers showing a range of different emotions for you to use in your instant messages.

But that’s not all – the avatar will imitate your facial expressions. You can even record videos that can be shared with your friends!

 

Intelligent Scan

The Samsung Galaxy S9 (Price Check) has a “new login method” called Intelligent Scan. This is not really a new feature, but a combination of the existing facial recognition and iris scanning capabilities.

In bright conditions, Intelligent Scan uses facial recognition to login. But when it gets too dark, the iris scanner kicks in. This allows for easier and faster logins in low light or super bright conditions.

Intelligent Scan addresses the key problem with the iris scanner – it doesn’t work in bright conditions. However, it is easier to fool than a point cloud facial recognition system like Apple Face ID, and future honor smartphones,

[adrotate group=”1″]

 

New Fingerprint Sensor

Samsung moved the fingerprint sensor to a central location right beneath the main camera at the back. This is a much better location, especially if you are left-handed. But that’s not all.

Samsung also used a new swipe fingerprint sensor. It is much easier and faster to register your fingerprint with this new sensor. This addresses a major criticism of the Galaxy S8 and Note8 smartphones.

However, its close proximity to the rear camera, and its swipe functionality means you will have to regularly clean the camera lens to avoid blurry pictures.

 

Hybrid SIM

As it was with the Samsung Galaxy S8, the Samsung Galaxy S9 (Price Check) will be offered with a nano SIM + microSD tray, or a hybrid SIM tray, depending on region. If you want dual SIM, dual standby capability, you will need to get the model with the hybrid SIM tray.

 

The hybrid SIM tray allows you to either use a second SIM card, or a microSD card, but not both at the same time. The microSD slot officially supports microSD cards of up to 256 GB in size.

IP68 Dust & Water Resistance

Like the Galaxy S8, the Samsung Galaxy S9 (Price Check) is IP68-rated for dust- and water-resistance. Best of all, you don’t even have to prepare it in any way before you dunk it into water! For more information how how Samsung achieved this feat, take a look at our article, Samsung Galaxy S7 IP68 Engineering Explained.

Officially, the Galaxy S9 can withstand complete immersion in water up to 1.5 m in depth, for up to 30 minutes. That means you can take it for jogs in the rain, reading in the shower or soaking in bath. Heck, you can even take it for a swim!

There are some caveats though. The IP68 rating applies to a specific set of test conditions : 15-35 °C, 86-106 kPa, 1.5 metre, 30 minutes. Even so, water may enter and damage the Galaxy S7 edge if it is exposed to “water moving with force“, like running water from a tap or waterfall, or ocean waves.

In other words, this is not a waterproof phone like the Oukitel K10000 Pro or the Kenxinda ruggerdised smartphones. It is IP68 water-resistant, so you need to be gentle with it. You can read more about this in our article – Samsung Galaxy S7 IP68 Engineering Explained.

 

Ergonomics

The Samsung Galaxy S9 (Price Check) has a 5.8″ bezel-less Infinity Display, so it does not feel like a large smartphone. In fact, it feels smaller than the 5.5″ Samsung Galaxy S7 edge, and even 5.2″ smartphones like HTC 10. This means it will feel more comfortable in smaller hands, and fit better in smaller pockets.

The large Super AMOLED display is beautiful as always. However, the WQHD+ resolution of 1440 x 2960 results in a non-standard 18.5:9 display ratio. Watching movies will result in some pillarboxing – a black bar on each side of the movie.

The Gorilla Glass 5 back looks fabulous… at first. It is easily smudged by oily fingerprints, because it lacks the oleophobic coating of the front Gorilla Glass 5 cover protecting the display.

Setting Up The Samsung Galaxy S9

The Samsung Galaxy S9 (Price Check) comes with Android 8.0 Oreo installed. Let’s boot it up, and see how easy it is to set-up!

 

Available Memory & Storage

The Samsung Galaxy S9 (Price Check) comes with 4 GB of LPDDR4x memory, of which 1.5 GB (37.5%) is available for use. That is a lot of bloat, equal to that of the Galaxy S8. With that in mind, 1.5 GB of memory is plenty of memory to run several applications simultaneously. In fact, it is more memory than what some low-end smartphones ship with!

The Samsung Galaxy S9 (Price Check) comes with 64 GB of internal flash storage, with 48.8 GB of free space for you to use. That is enough space to store about 11,000 photos, or 6 hours of 1080p videos, or just over 2 hours of 4K videos. If that’s not enough, you can top it up with a microSD card (up to 256 GB).

Camera Performance – Photos

The Samsung Galaxy S9 (Price Check) uses the 12 MP Samsung ISOCELL Fast SAK2L3 sensor in the dual aperture camera. It is capable of switching between the f/1.5 aperture, and the f/2.4 aperture.

The maximum 12 MP resolution is attained with the 4:3 aspect ratio, with 4032 x 3024 pixels, and a file size of between 3 MB and 5 MB.

Here are 6 high-resolution samples for you to check out. Click on them to load the full-sized photos, which you can also download to examine.

The new camera is just amazing. The detail and colour are top-notch, and the noise level is really low.

A word of caution – the f/1.5 aperture may offer great low-light performance, but it has a very narrow depth of field. If you don’t focus properly on your subject, it will end up blurred.

Too bad there’s no way to switch to the f/2.4 aperture for greater depth of field in the Auto mode. You can only switch apertures in the Pro mode.

Camera Performance – Video Recording

Like its predecessor, the Samsung Galaxy S9 (Price Check) is capable of recording 4K videos from both front and back cameras. However, Samsung still limits the 4K recording time to just 10 minutes. This was likely done to ensure that the sensor does not overheat the battery.

Below are four video samples, all taken without the use of gimbals.

Video Recording Test #1 : Piano (4K)

The camera’s resolution is really good. You can pick out the tiny signs in the background very clearly. It also demonstrated good control of the highlights – you can see into the Padini Concept Store in the background.

The optical and electronic image stabilisation capabilities also appear to have improved. It was almost as good as mounting the Galaxy S9 on a gimbal!

The recorded audio was clear, but still lacked the wider dynamic range of the HTC 10 (when HiRes Audio is enabled).

Video Recording Test #2 : Piano (1080p)

Even at this lower resolution, the amount of details captured by the Samsung Galaxy S9 is amazing. We also love how well it was able to control the highlights in the bright background. You can see the details that are usually washed out in other smartphones.

Video Recording Test #3 : Street Market (4K)

Look at how stable the recorded video was, even as we walked down this street market and looked around. It may not be as good as mounting the Galaxy S9 on a gimbal, but it comes real close!

Video Recording Test #4 : Street Market (1080p)

The 1080p walk-through appears to be even smoother than the 4K walk-through. So if you want the best-possible image stabilisation for your video, try recording in 1080p.

When it comes to work applications, the Samsung Exynos 9810 powering the Samsung Galaxy S9 (Price Check) is about 6% faster than the Exynos 8895 used in the Samsung Galaxy S8. This puts it at par with the Snapdragon 625 powering the ASUS ZenFone 4 Selfie Pro.

 

Battery Life – PCMark

We then tested the Galaxy S9’s battery performance using PCMark. It basically ran the PCMark work tests until its battery capacity dropped to 20%.

The Samsung Galaxy S9 (Price Check) lasted just over 9 hours in our battery test. That is almost 1.5 hours shorter than the Samsung Galaxy S8, and over 3 hours shorter than the Samsung Galaxy A8 2018. It only managed to beat the ASUS ZenFone 4 Selfie Pro by 25 minutes

Note : All four smartphones compared here have a 3,000 mAh battery.

Battery Recharging Performance

The Samsung Galaxy S9 comes with an adaptive fast charger with a power output of 18 W. Take a look at how fast it recharged its 3,000 mAh battery.

It took the Samsung Galaxy S9 (Price Check) about 108 minutes (1 hour 48 minutes) to recharge its battery from 20% to 100%. This is 21 minutes longer than it takes the Galaxy S8 to recharge the same battery capacity.

This gives it a battery life : recharging ratio of 5 : 1 – a rather disappointing performance.

Note : Our Samsung Galaxy S9 sample did not come with its charger. We used the Samsung Galaxy S8‘s charger instead. We will retest when we receive the official Galaxy S9 charger.

Gaming Performance – 3DMark

We tested the Galaxy S9’s gaming performance using 3DMark, using the Ice Storm Unlimited test.

What the Samsung Galaxy S9 (Price Check) lacks in work performance, it more than makes up in gaming performance. Its ARM Mali-G72 MP18 graphics processor was 37% faster than the ARM Mali-G71 MP20 used in the Galaxy S8.

The Samsung Galaxy S9’s CPU cores also delivered 28% faster physics processing than those of the Galaxy S8.

 

Our Verdict & Award

The Samsung Galaxy S9 (Price Check) looks almost identical to its predecessor, the Samsung Galaxy S8. While some see it as a “lack of innovation“, others point out that “if it ain’t broke, don’t fix it!

Whatever we may think of its familiar design, there is no doubt that the Samsung Galaxy S9 is the best Galaxy smartphone ever made.

Samsung basically fixed every major criticism of the Galaxy S8 smartphone. They moved the fingerprint sensor to a better position, and used a much better swipe-type sensor. They buttressed the iris scanner with the facial recognition system, allowing easy login in bright and low-light conditions.

The biggest hardware change was the addition of a dual aperture camera. It allows you to switch between an incredibly bright f/1.5 aperture and a f/2.4 aperture for greater depth of field. The dual aperture camera also appears to have improved image stabilisation.

Samsung also introduced a new Samsung ISOCELL Fast sensor in the Galaxy S9. It has large 1.4 µm pixels with Dual Pixel and Super PD capabilities. It has a 3-stack FRS (Fast Readout Sensor) that enables the new Super Slow-mo mode – the ability to record 720p video at 960 fps.

[adrotate group=”2″]

The other new Samsung Galaxy S9 (Price Check) features like AR Emoji, Bixby Live Translation and Intelligent Scan are software in nature.

The downside? The Samsung Galaxy S9 comes with the same 3,000 mAh battery, but has a shorter battery life and longer recharging time.

With the exception of the shorter battery life, the Samsung Galaxy S9 is better than the Samsung Galaxy S8 in every possible way. The Samsung Galaxy S9 is the Samsung Galaxy S8 perfected, and unreservedly deserves our Editor’s Choice Award. Congratulations, Samsung!

The ASUS ZenFone 4 Selfie Pro Up Close

Thanks to its thin bezel design, the ASUS ZenFone 4 Selfie Pro (Price Check) has a 5.5″ full HD AMOLED display in a form factor that is smaller, thinner and lighter than the iPhone 7 Plus. The display is protected by Gorilla Glass with a 2.5D contoured edge that merges seamlessly with the diamond-cut chamfer.

Everything is packed into a metal unibody chassis that is just 6.85 mm thick, and weighs only 147 grams. And yes, it has the 3.5 mm audio port. ASUS obviously put a considerable amount of work into the ZenFone 4 Selfie Pro (Price Check).

The ASUS ZenFone 4 Selfie Pro (Price Check) is powered by the Qualcomm Snapdragon 625, which they used most recently in their ZenFone 3 Zoom smartphone. Like the ASUS ZenFone 3 Zoom, it also comes with 4 GB of LPDDR3 SDRAM and 64 GB of internal flash storage.

 

Two Selfie Cameras!

This is the ASUS ZenFone 4 Selfie Pro’s killer feature – two front cameras for the perfect selfies. They consist of a main high-resolution selfie camera, and a wide-angle selfie camera for group shots. They are both supported by a soft LED flash that is designed to deliver enough fill light for selfies without overexposure and harsh shadows.

The main DuoPixel selfie camera (on the left) has a high-resolution Sony IMX362 sensor paired with f/1.8 lens. This camera boasts twice the light sensitivity of competing selfie cameras, and the astounding capability to take 24 MP photos. Heck, it can even record 4K selfie videos!

The wide-angle selfie camera (on the right) has a 5 MP Omnivision 5670 sensor paired with f/2.2 lens. With a 120° field of view, It allows you to capture a group shot (a wefie) without using a selfie stick.

The two cameras work individually – you switch from one camera to another, depending on whether you want a close up selfie, or a group wefie..

The 24MP DuoPixel Technology

You may be wondering how the ASUS ZenFone 4 Selfie Pro (Price Check) takes 24 MP pictures with a 12 MP Sony IMX362 sensor. Note that these 24 MP pictures are taken in a single shot, not stitched from multiple shots (e.g. ASUS Super Resolution). And no, they didn’t just double the pixels.

What they did was make full use of the Sony IMX362 sensor.

The IMX362 is a Dual Pixel Autofocus sensor, which means each pixel has two photodiodes. Usually, the two photodiodes are used separately to speed up autofocus, before being combined to capture the pixel data.

When you enable the ASUS DuoPixel Technology for 24 MP photos, the signals from the two photodiodes are not combined to create the final pixel. Instead, they are used to create two pixels, effectively doubling the resolution to 24 MP.

DuoPixel does not merely duplicate the pixels. The two photodiodes are effectively two pixels sharing the same microlens, each recording different beams of light. This is an elegant way to double the effective resolution of the photo. The only drawback – low light performance will suffer because each “pixel” now receives only half of the light. Not to worry though. You can disable DuoPixel for maximum low light performance.

The 16 MP PixelMaster 4.0 Camera

Even though the ZenFone 4 Selfie Pro’s main focus is the front camera capabilities, ASUS did not neglect the rear camera. It has 16 MP Sony IMX351 sensor coupled with f/2.2 lens and an LED flash. It is capable of recording 4K videos. The camera does not support OIS (optical image stabilisation), but is electronically stabilised on 3 axes when it records full HD videos.

If 16 MP is not good enough, this camera supports the ASUS Super Resolution technology that captures and combines four 16 MP photos to create a 64 MP photo. The camera also supports a new Time Lapse Mode with Power Saving, which lowers the screen brightness and puts the ZenFone 4 Selfie Pro into the Airplane mode. Now you can take long Time Lapse videos without worrying about running out of power.

 

Hybrid SIM & Fingerprint Sensor

The ASUS ZenFone 4 Selfie Pro (Price Check) has dual SIM, dual standby capability. It has a hybrid SIM tray for two nano SIM cards. The second SIM card tray (SIM2) doubles as a microSD card slot (up to 2 TB). Both SIM1 and SIM2 support 3G and 4G connectivity, but only one SIM card can connect to the 3G / 4G network – the other can only connect to a 2G network.

The ZenFone 4 Selfie Pro (Price Check) has a fast, all-aspect fingerprint sensor integrated into the Home button. Our tests showed that it requires just 12 finger presses to register a fingerprint, and is very fast and accurate in recognising the registered fingerprint.

ASUS SonicMaster 4.0

The audio aspect of smartphones is often overlooked. The ASUS ZenFone 4 Selfie Pro (Price Check) has an impressive set of hardware and software audio technologies, which ASUS markets as SonicMaster 4.0.

The ASUS ZenFone 4 Selfie Pro (Price Check) is Hi-Res Audio-certified, so you can enjoy 24-bit / 192 kHz audio. It also supports DTS Headphone:X for virtual 7.1 channel surround sound over your headphones. It has a 5-magnet speaker driven by the NXP Smart Amp with 40% more power output and less distortion.

Setting Up The ASUS ZenFone 4 Selfie Pro

The ASUS ZenFone 4 Selfie Pro (Price Check) ships with Android 7.1.1 Nougat, and ASUS confirmed that it will be upgraded soon to Android 8.0 Oreo. It also comes with 100 GB of free Google Drive storage for 1 year. Let’s show you just how easy it is to set-up the ZenFone 4 Selfie Pro.

 

The Ergonomics

The ASUS ZenFone 4 Selfie Pro (Price Check) may have a large 5.5″ display, but it is svelte at less than 75 mm wide and slim at less than 7 mm, even with the camera bump. It is surprisingly light at just 147 grams.

The large display with its full HD resolution is just perfect for watching movies. We also applaud ASUS for using an AMOLED display – it is generally more vivid and power-efficient.

We especially like the satin finish of the anodised chassis. It is smooth and comfortable to touch, and is resistant to fingerprint smears. The provided bumper case increases grip while protecting the ZenFone 4 Selfie Pro (Price Check) without making it overly bulky, or covering up its look.

[adrotate group=”1″]

 

Available Memory & Storage

The ASUS ZenFone 4 Selfie Pro (Price Check) comes with 4 GB of LPDDR3 memory, of which 1.8 GB (45%) is free to use. That is about as much memory as some smartphones ship with, so don’t worry about running out of RAM with the ZenFone 4 Selfie Pro!

The ZenFone 4 Selfie Pro (Price Check) also comes with 64 GB of internal flash memory. Of that, just under 51 GB is available to use. If that’s not enough, you can top it up with a microSD card (up to 256 GB).

Main Camera Performance – Photos

The ASUS ZenFone 4 Selfie Pro (Price Check) uses the 16 MP Sony IMX351 sensor for its main camera, paired with f/2.2 lens. The full 16 MP resolution is attained with the 4:3 aspect ratio. Each picture has a resolution of 4640 × 3480 and a file size of between 6 to 8 MB.

Here are 10 high-resolution samples for you to check out. Click on them to load the full-sized photos, which you can also download to examine.

Selfie Cameras Performance – Photos

The main selfie camera has an excellent 12 MP Sony IMX362 sensor with fast f/1.8 lens, and a resolution of 3928 x 2944. The wide-angle selfie camera has a 5 MP Omnivision 5670 sensor with f/2.2 lens, and a resolution of 2552 x 1912.

Here are three examples demonstrating the difference between the 12 MP main front camera, and the 5 MP wide-angle front camera.

The Omnivision 5670 sensor lacks the resolution of the Sony IMX362 sensor but did surprisingly well. While we naturally prefer the greater detail and colour saturation of the main selfie camera, the wide-angle selfie camera sure is useful in packing in more people, or more of the scenery in the background.

The wide-angle camera is best used in bright conditions. While it may not produce very high resolution photos, they are absolutely perfect for social media.

Main Camera Performance – Video Recording

We tested the main camera’s video recording performance in both 1080p and 4K resolutions. It supports EIS (electronic image stabilisation) but only when it records 1080p video.

While it supports Hi-Res Audio, that’s only for playback. It does not support Hi-Res Audio recording. The noise cancellation is decent, but the recorded audio is a little too bright and lacks punch.

Video Recording Test #1 : Piano (1080p)

The electronic image stabilisation worked well, greatly reducing the amount of hand shake in this video. However, the image itself appears to be somewhat blurred, with the colours muted and highlights overblown.

 

Video Recording Test #2 : Piano (4K)

The image quality when recording at 4K is so much better – sharp, with much greater detail and well-saturated colours. It’s worth trading the hand shake for the much better image quality.

[adrotate group=”1″]

 

Video Recording Test #3 : Street Market (1080p)

The image quality in this test was better than what we saw in the Piano test, although the highlights were still overblown. The 3-axis EIS worked well though.

 

Video Recording Test #4 : Street Market (4K)

The resolution is really good – you can take very good screenshots from the video. But the lack of image stabilisation means that 4K recording is best done when you are stationary… or well, just use the ZenFone 4 Selfie Pro with a gimbal.

 

Video Recording Test #5 : Video Selfie Test

Both front selfie cameras can record videos at the full HD resolution of 1920 x 1080. The main selfie camera is noticeably brighter, but the wide angle camera has better control of the background highlights. The video from the wide-angle camera has a noticeable fisheye effect – you get a much wider view, but the corners will be distorted.

Work Performance – PCMark

We tested the ASUS ZenFone 4 Selfie Pro’s performance using PCMark, which simulates work applications like web browing, playing video, writing text and editing photos.

ASUS ZenFone 4 Selfie Pro ASUS ZenFone 3 Zoom Samsung Galaxy A7 (2017) OPPO F1s

Writing 7692 7264 4948 4141
Photo Editing 10766 7824 5243 3933

Both the ASUS ZenFone 4 Selfie Pro (Price Checkand the ASUS ZenFone 3 Zoom use the same Qualcomm Snapdragon 625 SoC, but the Selfie Pro is almost 18% faster. In any case, they both did much better than the Samsung Galaxy A7 (2017), and the OPPO F1s in this test.

 

Battery Life – PCMark

We then tested the ASUS ZenFone 4 Selfie Pro’s battery performance using PCMark. It basically ran the PCMark work tests until its battery capacity dropped to 20%.

The ASUS ZenFone 4 Selfie Pro (Price Check) has a relatively small 3,000 mAh lithium-ion battery. It lasted 10.25 hours in our battery test, which is pretty good considering its higher performance. Incidentally, you can see that the battery is calibrated to show 100% for the first 7-8% of its total capacity.

[adrotate group=”1″]

 

Battery Recharging Performance

The ASUS ZenFone 4 Selfie Pro (Price Check) comes with a 10 W fast charger. It takes about 128.5 minutes (2 hours 8.5 minutes) to recharge its battery from 20% to 100%.

That’s a battery life : recharging ratio of just 4.8:1 – which is rather disappointing. After all, the ASUS ZenFone 3 Zoom uses the same 10 W fast charger to deliver a battery life : recharging ratio of 6.5:1.

Our Verdict & Award

While the smartphone industry is focused on dual-lens main cameras, ASUS is taking a chance with the ZenFone 4 Selfie Pro. Instead of placing two cameras at the back, they placed two cameras in the front. Now you have the choice of a high-resolution selfie camera, and a wide-angle selfie camera to fit more people or background into your picture.

The ASUS ZenFone 4 Selfie Pro (Price Check) is targeted at the Millennials who show a clear preference for taking and sharing selfies and wefies on social media. They generally do not care about the resolution of their pictures because they almost exclusively share their photos and videos with their family and friends on social media and instant messengers.

What matters far more is the ability to take good selfies and wefies. Even better if they can create dramatic shots without resorting to ungainly selfie sticks. That’s where the ZenFone 4 Selfie Pro’s wide-angle selfie camera comes in.

Its 120° field of view allows you to really pack in more people, or more of the background, into your selfies. And you can now take wefies, and more dramatic shots without using a selfie stick. Once you tried it, you will wonder how you ever “lived” without wide-angle selfie cameras!

[adrotate group=”2″]

Of course, not all selfies require a wide-angle camera. For close-up shots with your loved ones, you will want a regular selfie camera with a field of view of 80° to 90°. You will also want the photos to be in high resolution for posterity. For that, you use the ZenFone 4 Selfie Pro’s DuoPixel camera.

Not only can it take 24 MP selfies, it is paired with a fast f/1.8 lens and the awesome Sony IMX362 sensor with large 1.4 µm pixels. This makes for great selfies even in low-light conditions.

Even though it is a selfie-focused smartphone, ASUS did not skimp on the rear camera – it has a 16 MP camera with an LED flash. Neither did they skimp on its performance, memory and storage. It boasts a fast octa-core Snapdragon 625 processor, with 4 GB of RAM and 64 GB of storage. And all that is packed into a thin and light chassis, with a very nice 5.5″ AMOLED display.

It’s not all perfect though. We did not like the 1080p video recording quality of the rear camera, and its battery recharging speed is rather slow. And we wish ASUS would have paired the wide-angle selfie camera with a faster lens for better low-light performance.

All that in mind, the ASUS ZenFone 4 Selfie Pro is a great smartphone for those who love to take selfies. The wide-angle camera alone is worth the switch because it gives you better flexibility and creative options. For that reason, we think the ASUS ZenFone 4 Selfie Pro (Price Check) deserves our Reviewer’s Choice Award.

Gong Yoo Madness @ The ASUS “We Love Photo” Event!

When ASUS announced that Korean superstar Gong Yoo is the brand ambassador for the ASUS ZenFone 4 smartphones, they also announced that he would grace the ASUS ZenFone 4 launch event. We were amongst the lucky few to be flown to Taipei for the “We Love Photo” event. Join us for our complete coverage of the ASUS ZenFone 4 “We Love Photo” launch event!

With six videos and five smartphones in this one event, we divided the coverage into smaller, more manageable chunks :

 

We Love Photo?

ASUS called it the “We Love Photo” event because the new ZenFone 4 family of smartphones is all about mobile photography. In fact, this is the first family of smartphones in the world to feature dual-lens cameras in every single model!

[adrotate group=”2″]

We earlier shared with you the specifications and our hands-on previews of the five ASUS ZenFone 4 models. If not, well, check them out below :

Although the many models may be confusing, they are very simply divided into three categories. The Selfie series is designed to offer the ultimate selfie photographic capabilities, while the Max series is focused on battery life. The main series (without Selfie or Max) focus on the main camera capabilities.

 

The ASUS “We Love Photo” Event

The ASUS ZenFone 4 “We Love Photo” launch event was slated to start at 2 PM on 17 August 2017. But guess what – Gong Yoo’s fans started queuing outside the Next TV Studio in downtown Taipei 12 hours early – at 2 AM in the morning! About a hundred of his fans were permitted to join us in the event hall, while the others had to wait outside in specially-erected tents. Look at how crowded the hall was!

The “We Love Photo” event kicked off with a pre-launch show, followed by a welcome speech by ASUS Chairman Jonney Shih.

[adrotate group=”1″]

 

The ASUS ZenFone 4 Selfie Series

ASUS Design Director Jen Chuang then revealed the key features of the ASUS ZenFone 4 Selfie smartphones. These are designed to offer the ultimate selfie photography capabilities, so they all boast a dual-lens camera in the front!

 

ZenUI 4.0 & The ASUS ZenFone 4 Series

ASUS Head of Global Content Marketing Marcel Campos then talked about the new ASUS ZenUI 4.0. He revealed that not only will the new ASUS ZenFone 4 smartphones be upgraded to Android Oreo with ZenUI 4.0, the entire ZenFone 3 series will also receive the same upgrade!

He then shared the key features of the mainline ASUS ZenFone 4 smartphones. As every ASUS ZenFone 4 smartphone is powered by a Qualcomm Snapdragon processor, he also invited ST Liew, VP & President of Qualcomm Taiwan, to talk about Qualcomm’s partnership with ASUS.

The ASUS ZenFone 4 Selfie Pro (ZD552KL) Preview

On 17 August 2017, ASUS launched the ASUS ZenFone 4 Selfie Pro (ZD552KL) smartphone with Korean superstar Gong Yoo at the Next TV Studio in Taipei. Let’s take a look at the specifications and key features of the ASUS ZenFone 4 Selfie Pro, as well as our hands-on preview of the first unit in Taipei!

 

The ASUS ZenFone 4 Selfie Pro (ZD552KL) Smartphone

The new ASUS ZenFone 4 Selfie Pro smartphone is designed to offer selfie fans greater flexibility in taking their selfies and wefies. Let’s check it out!

Two front cameras for perfect selfies!

Like other ZenFone 4 models, the ZenFone 4 Selfie Pro has two cameras on one side. This is similar to how professional photographers use separate fixed focal length lenses with their DSLR cameras for the best possible quality, and to allow them to compose photos with different perspectives.

The big difference of the ZenFone 4 Selfie Pro is that its cameras face the front, so that it can shoot perfect self or group portrait photos (wefies).

2X brighter low-light selfies with ASUS SuperPixel camera!

The main selfie camera on ZenFone 4 Selfie Pro features a F1.8 aperture lens and the latest Sony Exmor RS IMX362 image sensor. It has a large 1/2.55” size format, and large 1.4μm pixels. Combined with the ASUS SuperPixel Engine that intelligently controls sensor light sensitivity and reduces image noise, ZenFone 4 Selfie Pro is able to achieve twice (2x) the light sensitivity of a typical smartphone camera and helps users take beautifully clear and vivid selfies, day or night, indoors or out.

120 degree wide-angle second front camera

The ZenFone 4 Selfie Pro’s second front facing, 120-degree wide angle camera allows you to capture photos and videos that fit more of your environment into the frame, so you can include a scenic background in your shot or gather even more friends together and have fun taking wefies – without needing to use an inconvenient selfie stick!

Premium Metal Unibody

The ZenFone 4 Selfie Pro features a beautifully slim, metal unibody that was created by an advanced manufacturing process known as Nano Molding Technology (NMT). Its display is covered by tough Gorilla Glass which is then contoured at the edges.

The metal unibody also features a beautiful, diamond-cut chamfer and engraved detailing around the rear camera lens that shimmers with a radiant luster when viewed from different angles. Although the ZenFone 4 Selfie Pro has dual front cameras, it is only 6.85mm thick and weighs only 147 grams.
