Asus Zenfone 11 Ultra smartphone review - Suddenly grown up

The departure. Asus has broken one of its traditions: The 11th-generation Zenfone is no longer compact, and Ultra has been added to its name. Its flagship performance is the same—supposedly, its cameras have been improved. Our review will unveil which benefits the phone's new size brings.

In recent years, Asus' Zenfone series has always been a guarantor of flagship performance within compact devices. In 2024, the manufacturer has ditched this concept. The Zenfone 11 has had the suffix Ultra added to its name, and it has grown a lot. While the Zenfone 10 had a display diagonal of 5.9 inches, the new Zenfone 11 Ultra measures in at 6.78 inches.

You can get the Zenfone 11 Ultra in two versions: with 12 GB RAM and 256 GB storage, or with 16 GB RAM and 512 GB storage. Furthermore, there are four colors available: black, gray, blue and orange. Our test device is blue and features the larger storage configuration.

Case - Asus relies on glass and metal

The Zenfone 11 Ultra's frame is made from metal. Its display and back are protected by glass. Gorilla Glass Victus 2 is installed over the display, and the manufacturer has not named which type is used on the back. The display is straight and the frame is very angular. 

The smartphone is IP68-certified against dust and water. The placement of its USB port is a little unusual. It doesn't sit in the middle of the bottom of the case but rather further left. Its build quality is good. The device can barely be twisted. During our test phase, we never noted any scratches. The buttons have a good pressure point but the volume rocker wobbles a little. 

The camera module protrudes quite a bit out of the back and is positioned very high up. As a result, the device sits securely on the table and only wobbles when inputs are made high up on the display. The decor on the back is only visible—you can't feel it.

Connectivity - The Zenfone 11 Ultra has an audio jack

Even as a flagship, the Asus Zenfone 11 Ultra still features a 3.5-mm audio jack. However, its storage cannot be expanded. NFC is on board, as is dual-SIM support. Unfortunately, the USB-C connection only supports USB 2.0. In combination with a Samsung 980 Pro hard drive, we measured transfer speeds of 31.79 MB/s. ExFAT and NTFS are supported for transferring data onto external storage devices.

Software - The Zenfone 11 Ultra with short support

The Asus Zenfone 11 Ultra comes delivered with Android 14. Its UI hasn't been changed too much compared to stock Android. When setting up the phone, you can even choose whether you would like to install the Asus UI or stock Android.

Ex works, the phone comes mostly with software from Asus and Google—it only has third-party apps from Meta installed. After setting the phone up, 21 GB of its storage is taken up. The smartphone features a high-performance mode that is automatically activated when gaming or performing benchmarks.     

Asus only states a short time period when it comes to update delivery. The Zenfone 11 Ultra is set to receive two large Android updates and four years of security patches. At the time of testing (April 2024), the smartphone still ran with the version from December 2023.

The manufacturer offers a range of additional options, such as being able to assign the phone's buttons special features—plus, you can also activate commands by tapping the back of the device. Moreover, several apps support using two user profiles at the same time. The "edge tool" is a short menu which gives you quick access to various apps.

Furthermore, Asus advertizes a range of AI functions. The smartphone will supposedly receive a live translator function for telephone calls, a translator for voice recordings as well as AI-generated wallpaper. However, these three functions are still in the beta phase. The phone already features an AI-supported noise suppression and AI-assisted search function.

Communication and GNSS - The Zenfone 11 Ultra is WiFi-7 ready

The Asus Zenfone 11 Ultra supports Wi-Fi 7, so this includes the 6 GHz band. However, in combination with our reference router, the Asus ROG Rapture GT-AXE11000, the smartphone showed significant connectivity fluctuations. Its transmission rates were also lower than those of its predecessor, the Zenfone 10.

The Zenfone 11 Ultra is also 5G-ready. The global version supports 20 5G bands and 25 LTE bands. This ensures good network coverage even when travelling. The Zenfone 11 Ultra is dual SIM-capable using two physical SIM cards, whereas eSIMs are not supported.

Telephone features and call quality - AI noise suppression on the Zenfone

Asus uses its own telephone app on the Zenfone 11 Ultra. The software is structured clearly and—apart from the AI-assisted noise suppression—it doesn't feature any additional functions. The Zenfone doesn't offer any special features during calls. The user's voice is transmitted clearly and we noted no background noise. The device gets nice and loud when the loudspeaker is used and ambient noise is filtered out well.

The Zenfone 11 Ultra features one lens more on the back than the Zenfone 10. The new addition is its 32-MPix camera with a 3x optical zoom and OIS. It complements the 50 MPix main camera (IMX 890) with gimbal stabilization and the 12.5 MPix ultra-wide-angle camera.

The smartphone has a pro mode where you can control focus, exposure time, ISO and white balance manually. You can record video at a maximum of 4K and 24fps using the main camera, and at 4K and 40fps using the ultra-wide-angle lens. Furthermore, there are modes for slow-motion, time-lapse and portrait videos.   

The phone has a 32-MPix lens installed on the front. It uses pixel binning, resulting in a resolution of 8 MPix. It can record video at a maximum of FHD and 30fps. In total, its picture and video quality is good. Its video stabilization is particularly successful but its sound recordings have a bit of background noise. 

The photos taken during our test look natural but in comparison to the other flagships, they are missing a little sharpness. In low-light conditions, the software lightens subjects quite a bit, which unfortunately leads to considerable amounts of noise.

Accessories and warranty - Asus includes a case but not a power supply

Asus delivers the Zenfone 11 Ultra with a USB cable (USB-C to USB-A) and a black, solid plastic protective case. In addition, it comes with a SIM tool and all the usual instructions. A power supply isn't included. In the United States, the Asus phone comes with a standard 12-month warranty.

Input devices & operation - Unlock the Zenfone 11 Ultra quickly

The Zenfone 11 Ultra doesn't come with a screen protector preinstalled. The panel is nice and smooth and inputs are recognized reliably right into the corners. For games, the phone supports a touch sampling rate of up to 144 Hz and when used normally, it scans the screen for inputs at up to 120 Hz. You can enhance the display's sensitivity by activating a so-called glove mode.

You can unlock the phone via 2D facial recognition or an optical fingerprint sensor which is built into the display. Both work very reliably and quickly. You can skip the lock screen entirely. The phone's vibration motor made a good impression, too; it is nice and quiet and crisp.

Asus uses Google's keyboard which works reliably. Due to the device's large size, it is a little more difficult to use the device with one hand compared to its predecessor. It supports a one-handed mode.

Display - The Zenfone 11 Ultra gets really bright

Sub-pixel array
Sub-pixel array

The Zenfone 11 Ultra is fitted with a 6.78-inch AMOLED display with a refresh rate between 1 and 120 Hz in normal use. You can manually set the rate to 60 or 120 Hz. During our measurements, the panel also showed an impressive maximum brightness level. 

We noted an average brightness of 1673.6 cd/m², resulting in the Zenfone 11 Ultra surpassing well-known competitors such as the Samsung Galaxy S24+ and the iPhone 15 Plus. It gets twice as bright as its predecessor, the Zenfone 10. During the APL18 and HDR measurements, the panel even reached 2,409 and 2,458 nits, which means it nearly reaches the 2,500 cd/m² as promised by the manufacturer. Furthermore, its illumination is even.

During our measurements, we noted some screen flickering at a frequency of 486 Hz. The Zenfone 11 Ultra offers a special screen mode that reduces the flickering at low brightness levels and when we measured this, it resulted in a much lower amplitude. You can select an always-on display within the UI. However, it isn't a true AoD, as it switches off after several minutes.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 486 Hz

The display backlight flickers at 486 Hz (worst case, e.g., utilizing PWM) .

The frequency of 486 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17673 (minimum: 5 - maximum: 3846000) Hz was measured.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White

Performance - The Zenfone 11 Ultra delivers great performance

When it comes to the Zenfone 11 Ultra, Asus relies on the latest top-of-the-range processors from Qualcomm, namely the Snapdragon 8 Gen 3. Our test model is additionally fitted with 16 GB RAM. As a result, the Zenfone completes everyday tasks just as fast as you would expect. Its system performance is buttery smooth and apps are opened quickly.  

The Zenfone 11 Ultra didn't show a clear picture in the benchmarks. While it came ahead during Geekbench 5 and 6 as well as during PCMark, it performed worse in CrossMark, for example. Overall, however, its performance is very good.

The Asus phone did impressively well during the storage benchmark. The Zenfone came out on top with its UFS-4 storage and compared to the Google Pixel 8 in particular, it sometimes offered twice the speeds.

The Zenfone 11 Ultra is equipped with an Adreno 750 as its graphics unit. As a result, the Zenfone came up trumps amongst the comparison devices during the 3DMark test. During GFX Bench, on the other hand, quite a few of its competitors did better and all-in-all, the results of this benchmark were a little puzzling. Its off-screen values are conspicuously low and its on-screen values are consistently high. 

At the same time, the phone's refresh result must be increased manually in order to achieve decent results. Current games are no problem for the smartphone. PUBG Mobile runs smoothly using the settings Ultra HDR and the picture rate Ultra. Our test device is only DRM Widevine Level 3 certified, but the retail versions should have the Level 1 certificate.

Emissions - Asus keeps heat within limits

Temperature - The Snapdragon gets warm but not hot

The Asus Zenfone 11 Ultra always remains nice and cool in daily use. It also gets warm during intensive gaming sessions, but not hot. Under extreme load during the Burnout benchmark, we measured a maximum of 43.2 degrees Celsius on the top and 43.9 degrees on the bottom.

Throttling set in during the stability test due to the heat, but roughly at the same level as the comparison devices.

Speakers - Great stereo sound on the Zenfone 11 Ultra

The speakers in the Asus Zenfone 11 Ultra do a very good job. They are loud without sound getting distorted and they deliver balanced stereo sound. At high volumes, we noted some vibrations in the frame and on the back, but they were never distracting. Headphones can be connected to the Zenfone via an audio jack, but its signal-to-noise ratio is very low at 67.79 dBFS.

Bluetooth headphones could be paired without any problems during our test. The Zenfone 11 Ultra supports the following codecs: SBC, AAC, aptX, aptX HD, LDAC, aptX Adaptive audio, LC3 and Opus. The smartphone comes with an audio assistant preinstalled. This includes an equalizer that can be adjusted for individual end devices.

Runtimes - The Zenfone can't live up to expectations

The Asus Zenfone 11 Ultra features ideal conditions for long battery runtimes: It has a 5,500 mAh battery and an AMOLED display with LTPO. In our realistic WiFi web surfing test, the Zenfone only ran out of battery after 16.5 hours. A good value in itself.

However, with the exception of the Google Pixel 8, all comparison devices lasted longer—although some of them are fitted with significantly smaller batteries. Asus states the phone supports fast charging at a maximum of 65 watts as well as Quick Charge 5.0. Unfortunately, no suitable power adapter is included. We achieved a maximum charging power of 32 watts when using an Anker Powerhouse 555. The Zenfone 11 Ultra took around 80 minutes to fully charge in the test. The Zenfone also supports Qi wireless charging at up to 15 watts.

Verdict - The Zenfone in large features highlights, but it doesn't come out on top

Asus Zenfone 11 Ultra review. Test sample provided by Asus Germany.
Asus Zenfone 11 Ultra review. Test sample provided by Asus Germany.

Asus has forged a new path with its Zenfone 11 Ultra. Its new size positively impacts the phone's display, battery life and speakers. It remains unknown whether installing the third camera was only possible due to there being more space on the back. However, Zenfone has also lost its unique selling point, opening the device up to much more competition.

The Zenfone 11 Ultra's super bright and well-balanced display is most impressive. Together with its truly good speakers, it offers a very pleasant audio-visual experience for videos as well as games. Its performance is beyond question: It is fitted with a top-league processor, RAM and storage, resulting in great working speeds.

You'll have to make some compromises when it comes to its camera: Although it shows great progress compared to its predecessor, it just can't compete with other top-of-the-range smartphones like the Google Pixel 8Xiaomi 14 or the Apple iPhone 15 Plus when it comes to depicting details. Its photos are anything but bad, but they can't quite be assigned to the top smartphone class. Asus has to make up ground when it comes to updates, too. Google and Samsung both offer significantly longer support.

The Asus Zenfone 11 Ultra is a great smartphone without any real flaws. However, it has lost its unique selling point and it can't quite contend with the best when it comes to smaller details.

If you are on the hunt for a particularly compact high-end smartphone, then you should take a look at the Xiaomi 14 or the Samsung Galaxy S24. The Google Pixel 8 boasts a better camera and longer update support. Furthermore, it has already been on the market for quite a while, making it a lot cheaper.
