Asus Zenfone 6 review: An absolute steal (Latest version)

The first article I ever wrote was about the launch of the Asus Zenfone 2. It has an incredible 4 GB of RAM and costs just $ 299 – an absolutely crazy price at that time for that great memory!

Four years later, Asus retained this flagship specification legacy at a mid-range price. While other manufacturers are already charging more than $ 1,000 for their devices, Asus managed to keep its prices low while providing some of the best hardware on the market.

It is Android Authority's Asus Zenfone 6 review.

About this review: While writing this review, I used an Asus Zenfone 6 supplied by the manufacturer over a period of 11 days in the US and Taiwan. I used the Black model with 8 GB of RAM and 256 GB of storage, which used ZenUI 6 on the April 1, 2019 security package.

Asus Zenfone 6 review: The big picture

The Asus Zenfone 6 is the company's latest affordable flagship. It doesn't really play as aggressively as the gamer-focused Asus ROG phoneBut it still seems high enough to get attention from a wide variety of people.

As a headphone jack, Qualcomm Snapdragon 855 processor, 48MP flip camera, microSD card extension, and dedicated quick action button is not enough to interest you in this device, maybe the price. Asus offers this phone for just $ 499, putting it firmly between them Pixel 3a and OnePlus 7 Pro. In one way, it offers the best of both worlds.

Asus managed to marry flag specifications with mediocre prices.

There are a few features that are missing from this device, which can irritate some consumers, but I personally felt it was good to get rid of this price point. Wireless charging and water resistance are the major offenders, but most mid-range devices do not have these features, so I give it a pass.

What's in the box

  • 18W loading brick
  • White USB-A to USB-C cable
  • Clear protective case
  • Asus earphones

The Asus Zenfone 6 comes with an 18W charging brick, a USB-A to USB-C cable, a pair of Asus earbuds and a soft protective case. The case has a cut near the back for the new flip-up camera. These earbuds are set by 1MORE and actually sound decent. However, if you want to make better use of the headphone jack, you can get it even better sound quality for just a little extra cash.

  • 190g
  • 159.1 x 75.44 x 9.1 mm
  • No notch
  • Environmental light sensor
  • Double SIM Slide
  • headphone
  • Flip-up camera
  • Quick action button
  • Supported fingerprint reader
  • MicroSD card slot

The Zenfone 6 has a clean design that will appeal to most consumers. It's not nearly as gamer-focused as the Asus ROG phoneBut the robotic flip camera and blue accents give it a slightly more aggressive look than phones like the Pixel 3.

The body of this device is made of Gorilla Glass, and sports an aluminum frame around the rim. It feels completely and premium in hand, so much so that I first thought it was totally metal. Unfortunately, there is no wireless charging in this device, so it can also be made of metal.

This phone has a healthy number of ports and ports. On the right of the device there is a power button with a nice blue accent to fit the Asus logo on the back, volume rockers and a dedicated quick action button. This button is standard Google Assistantbut you can change it to do a number of things, such as a screenshot, open the camera or change the sound.

Customizable buttons will always be met with praise from us here at AA.

There are no physical buttons on the left side of the phone, but you will find a dual SIM tray with an expandable storage slot. The bottom of the device includes a headphone jack, USB-C port, and a speaker grid.

The back of the phone houses a rear fingerprint reader and a dual camera array. This camera system is one of the highlights of the device. It physically flips around the top of the phone, which allowed Asus to keep the screen free of cuts and inks. We'll find out later in this, but just know that this unique camera array is certain some heads can be.

This device does not have an officer IP rating for water and dust resistance, but it's not surprising. Any mobile phone with a moving part is extremely difficult to make water resistant, and the flip-up camera on the Zenfone 6 is the Achilles heel in this case.


Asus Zenfone 6 - screen upright

  • 6.4-inch IPS LCD screen
  • 2.340 x 1.080 resolution, 403ppi
  • 19.5: 9 aspect ratio
  • Gorilla Glass 6

The most acute problem with the Asus Zenfone 6 is probably the LCD performance. Most high-end smartphones (and even some mid-ranged ones) Use OLED panels for deeper blacks, better battery life, and features like always on each other. While on OLED display can be illuminated individual pixels, LCD technology requires the entire display to be illuminated, to drain more battery and reduce the dynamic range.

I missed OLED very much while using this device.

The other problem with this screen is brightness. It gets on 600 nits, and I had to keep the Zenfone 6 at maximum brightness throughout my time. It's hard to see the screen outside, and I usually have to keep my phones about half clear daily.

The things considered are the quality of this panel very well, in several respects. It has a 100 percent DCP-I3 coverage, which means it can show the entire color space, and the panel is made of Gorilla Glass 6. It should be more scratch resistant than phones with older Gorilla Glass versions.

The show is not obstructed by any kind of indentation. This phone uses a flip-up camera and the result is a full screen display. There is another noticeable chin on the bottom of the screen, but it's not as big as the on the Pixel 3.

  • Qualcomm Snapdragon 855
  • Octa-core
  • Adreno 640 GPU
  • 6GB or 8GB RAM
  • 64GB or 256GB storage
  • MicroSD expandable storage

Given the specifications, the Zenfone 6 is sporty, it is no surprise that it is absolutely flying. I didn't use or sound the device during my time. The lightweight software experience helps to make the device feel fast, and the 6GB or 8GB RAM allows you to multitask without forcing any applications out of memory.

This phone gets hot under a heavy load. The Zenfone 6 has become warmer than most glass-back devices, and it even stopped charging due to overheating. Gaming will probably get the phone very hot, so you can break every now and then.

Asus Zenfone 6 Benchmark - AnTuTu
Asus Zenfone 6 Standard - 3DMark
Asus Zenfone 6 Measure - Geekbench

The Asus Zenfone 6 performed very well in the benchmark. In AnTuTu it's even about 370 000 points beat the Samsung Galaxy S10 Plus. 3DMark achieved a slightly lower score than the S10 Plus at about 5,500 points, and Geekbench 4 gave the Zenfone the smallest edge over the S10 in single-core performance, while only falling into the multi-core test.

If you really want the best performance, you can enable AI Boost Mode, although I don't recommend it. This will drain the battery even faster than it already does.


Asus Zenfone 6 put the camera on the table

  • 5,000mAh
  • Qualcomm Quick charge 4.0 (18W)
  • No wireless charging

Despite the 5000mAh battery, the battery life of the Zenfone 6 was no more than average. I cut about six and a half hours on time, which is decent, but compared to Samsung Galaxy S10 Plus or Huawei P30 Pro it was a little low. I could make one charge at the end of the day, but you probably won't get two full days as we saw on the Huawei P30 Pro.

A big problem with this phone seems to be a high level of standby drain. One night I went to sleep 26 percent and woke up to a dead device. Most phones have a fairly good standby battery life, so it's a bit strange to see this device drain so fast. The Zenfone 6 also takes a while to upload. It supports 18W wired charging, but the capacity of the battery makes it longer than most devices. I would like to see Asus developing its own fast charging technology, especially when the battery is used so large.

  • Flip camera
  • Default: 48MP, f/1.79
  • Wide: 13MP ultra time
  • Pixel-binned images at 12MP

We should note that a software update has recently been released designed to update the camera's performance. Unfortunately, our unit was unable to install the update for an unknown reason. We're trying to fix it and will update our Zenfone 6 review with new images as soon as it's resolved.

The Asus Zenfone 6 uses the 48MP Sony IMX586 primary camera sensor, and a 13MP wide-angle camera. It's not unique to devices this year – almost every high-end smartphone leaned on this high-sensor to get sharp images. The really unique part of this camera is how it doubles as a selfie shooter.

Most manufacturers use popup camera or punching Designed to achieve a full-screen display, but Asus thought out of the box and developed a camera that physically fliped on the phone. This brings the flexibility of the 48MP and wide-angle rear guns face to face with the owner for maximum selfies.

Asus Zenfone 6 camera angle

The flip-up camera can swing around a full 180 degrees, allowing you to take images at any angle in between. While it may not seem so useful, it puts some interesting features like automatic panorama mode or object detection. The former allows the user to stand still while the phone is taking a panorama image, and the latter uses counter-tracking of objects to rotate the camera and & # 39; a topic around & # 39; to follow stage. Although not everyone will use these features, they are pretty cool to have.

As for the true image quality, the Zenfone 6 performs wonderfully. Dynamic range is solid but not to be washed, and the sharpness is quite good. Asus doesn't seem to have made much effort to vote for this camera, but sometimes it's a good thing. I prefer a more subdued picture to something that is over-saturated or overheated.

That said, this phone seems to have a problem with brighter red. In the picture of flowers above, you can see the device has problems processing the red channel. It is possible that this will be resolved in an upcoming software update, but we will not hold our breath.

Low light images were pretty good and didn't show as much noise as we expected. The device struggled in more extreme low light situations, but the long exposure helped to get more light out of a dark scene.

Portrait mode on this phone is also very good. The Zenfone 6 does a good job of removing the subject from the background while still retaining a natural look at the distorted background. I've seen a little too many skin phenomena on portrait mode photos & # 39; but it's not terrible.


  • ZenUI 6
  • Android 9 Piece

The Asus Zenfone 6 runs ZenUI 6, which is a complete refreshment of its previously terrible software. The new skin is lightweight, with just a few software additions on top of "stock" Android 9 Piece.

Asus included a dedicated screen recorder, AI Boost for intense usage sessions, and even an FM radio. The only questionable program you find on this phone at startup is the Asus Data Transfer program, which is still useful if you want to move data between devices.

Overall we are delighted to see the switch to a simpler interface. Asus devices were previously stacked with no-use apps and services, so it's a good idea to see a user interface that gives the user more control over what is on their device.


  • 3.5 mm headphone jack
  • NXP TFA9874 smart amp
  • double speakers

The Asus Zenfone 6 features a dual-speaker setup. There is one speaker at the bottom of the phone and another doubling up as a top plug in the top. The speakers sound decent but do not bark like many smartphones currently in the market.

The phone uses a smart amplifier, which is supposed to twist the sound at high volumes. This is usually true. While other devices sound over a certain volume, the Zenfone 6 is relatively clear. If you have the phone upside down, however, the camera will start rattling the 50 percent volume point. If you listen to music, we suggest keeping the phone on the face.

The headphone jack is a nice surprise.

Surprisingly, this device plugs into a headphone jack. Many manufacturers have turned away from wired audio, but Asus embraced it in its last few devices. Sound quality from a headphone jack will always be better than Bluetooth, and the flexibility of analog audio is also appreciated.

If you prefer to go wireless, the Asus Zenfone 6 supports Bluetooth 5 with the high fidelity aptX HD, LDAC and HWA codecs.

Value for money

  • Asus Zenfone 6: 6GB RAM, 64GB ROM – 499 EUR / $ 499
  • Asus Zenfone 6: 6GB RAM, 128GB ROM – 559 euros
  • Asus Zenfone 6: 8GB RAM, 256GB ROM – 599 euros

The Asus Zenfone 6 starts with just 499 euros and is an aggressively priced device. It subscribes to the OnePlus 7 Pro base model with 200 euros with almost the same core specifications – and includes a headphone jack to get started.

Conversely, the OnePlus 7 Pro includes a larger, better display, a probably better UI, faster storage, and a telephoto lens. If you prefer sounds, wide angles, expandable storage and a dedicated quick action button, it is difficult to beat the Zenfone 6.

This phone fits securely between Pixel 3a and OnePlus 7 Pro.

If you want to spend a little less, you can get the Google Pixel 3a for $ 399. The 3a knocks out the Zenfone in image quality and image quality, but the user interfaces are very similar, and the keyboard shortcut on the Zenfone 6 is probably more versatile than the Active Edge of Pixel 3a. For the extra $ 100 you also get expandable storage, a glass building and a bigger battery.

While the base model Zenfone 6 is officially priced at $ 499, Asus declined to announce US high-level model prices. If you are in Europe, you can get 6 GB of RAM and 128 GB of storage for 559 euros, or 8 GB of RAM and 256 GB of storage for 599 euros.

Just this week, Asus also announced a special 30-year-old Zenfone 6, with 12 GB of memory, 512 GB of memory and 30 months of warranty. We don't know any pricing details on this device, but it will undoubtedly be very expensive.

Asus Zenfone 6 review: The verdict

For $ 499, the Asus Zenfone is an absolute steal. Many flagships that cost $ 1,000 or more do not offer the number of features found in the Zenfone 6. The new user interface also makes this phone a joy to use.

The Zenfone 6 may not have wireless charging or an official water resistance certification, but it has many things that people care about and even more features that users will appreciate. The headphone jack, expandable storage, notification LED, and quick action ranges are all good extras. These features are set on a strong base charged by the Snapdragon 855 processor and healthy dose RAM. It is difficult to recommend this device at a price.
