Case - Small smartphone with IP certificate
Asus manufactures the Zenfone 8 with a metal frame and a back made of Corning Gorilla Glass 3. The display is protected by Corning Gorilla Glass Victus. There is also a choice of two colors, "Obsidian Black" and "Horizon Silver", and the casing is protected against submersion in water and dust according to IP68.
With a weight of 169 grams (~6 oz), it is not a very light device and despite the small screen size, it is not as small as the Apple iPhone 12 mini but rather resembles the Google Pixel 5.
Features - Notification LED and jack connector
Asus does without a microSD card slot in the Zenfone 8. Instead, two SIM cards can be inserted that support VoLTE and VoWLAN. The USB-C port can transfer data with the USB 2.0 standard and a 3.5 mm jack is available for wired headsets. DRM Widevine L1 is also supported and the Camera2 API is available with Level 3.
A notification LED next to the charging port also informs about system events and shows the battery's state during charging.
Software - Pure Android on the Zenfone 8
Asus' Zenfone 8 runs a pure Android 11 with security patches as of April 5, 2021. However, Facebook, Instagram, Netflix, and Asus' Transfer app are some secondary or third-party apps, of which only the latter can be uninstalled.
Communications and GNSS - Fast WLAN meets 5G
Besides GSM, 3G and LTE, the Zenfone 8 can also establish mobile connections in 5G networks. Added to that are NFC, Bluetooth 5.2, and WiFi 6 for short-range communication.
High speeds are achieved with our reference router Netgear Nighthawk AX12, which is sufficient for the first place in our test field.

Asus' smartphone can use GPS, GLONASS, BeiDou, Galileo, QZSS and NavIC to determine the location. We achieved a positioning accuracy of up to three meters (~10 feet) outdoors with the app "GPS Test".
On our obligatory bike tour, the track recorded with the Asus Zenfone 8 shows a smaller deviation than our reference device Garmin Edge 500 on long straights and curves.
Phone features and voice quality - High volume during calls
The Zenfone 8's telephony app allows direct access to recent calls and a numeric keypad. Another tab displays saved contacts. A high volume is possible during calls and background noise is reliably filtered out. Participants can also be understood clearly on both sides.
The VoLTE and VoWLAN features are also available, but no eSIM can be used. In addition, only the preferred SIM card can use 5G.
Cameras - Solid image quality
Asus equips the Zenfone 8 with a 64 MP main camera that takes close-ups with many details in the focus area. Colors look natural and our test subject is evenly lit. Panoramic pictures also show many details, but might look a bit too dark depending on the ambient light. When objects in the picture are brought closer with the software zoom, the level of detail decreases a bit, but the subject is still easily recognizable. Pictures taken in low-light conditions only show blurry details and pale colors.
A slightly better result is achieved with the night mode. Besides the main camera, the 12 MP IMX363 sensor is available for ultra-wide-angle shots, which is used in the Pixel 5 for the main camera. Colors look more vivid, but a slight graininess can be noticed on the entire picture. Various picture settings can also be adjusted manually via a Pro mode.
The front-facing camera also records pictures with 12 MP and shows many details as well as natural colors. A beautification mode can be applied in the camera app and the shutter speed can be adjusted manually. Video recordings made with the main camera offer a similar quality as shown in our test photos. An image stabilizer ensures a smooth picture and the quality can also be influenced in a professional mode. Possible resolutions are HD, FullHD with 30 and 60 fps, 4K with 30 and 60 fps, and 8K.

Our test image of the ColorChecker Passport shows that the camera of the Asus Zenfone 8 captures colors a bit too brightly under controlled lighting conditions. The chart displays many details, but shows a contrast weakness in the lower corners.
Accessories and warranty - protective case for Zenfone 8 included
The Zenfone 8 comes with a USB power adapter with a matching USB-C cable, a SIM needle, and a protective case made of rigid plastic.
Asus grants a warranty period of 24 months for the Zenfone 8.
Input Devices & Operation - Reliable InScreen Fingerprint Sensor
Google's GBoard is available for text input on the Zenfone 8. The touchscreen responds very directly to inputs and is also well suited for longer drag-and-drop movements.
An optical in-screen fingerprint sensor is also available for unlocking the smartphone, which responded very well to stored prints in our test. Face recognition can also be set up and used reliably.
Display - Bright AMOLED screen
The screen of the Asus Zenfone 8 consists of a 5.92-inch AMOLED panel and offers a resolution of 2400 x 1080 pixels. The average brightness is a maximum of 759 cd/m² and reaches 1,007 cd/m² in the APL50 test. However, only 425 cd/m² are achieved without an enabled ambient light sensor.
For brightness levels below 45 percent we measure PWM in a frequency range between 160.8 and 459 Hz. From 27 to 64 percent, the frequency range narrows to 454.2 to 520.8 Hz. Above 64 percent, we only notice the refresh rate of 120 Hz. There is an entry "DC dimming" in the display menu, but it has no function.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 495 Hz | ≤ 45 % brightness setting | |
The display backlight flickers at 495 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 45 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 495 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 19210 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Besides the excellent contrast ratio of an OLED panel and the associated black value of 0 cd/m², the Zenfone 8 also displays colors with an extremely low deviation with the preloaded profile "Cinema".
In the settings menu, the color temperature can be adjusted manually with other pre-made profiles or a slider.

Battery life
Asus' smartphone achieves a runtime of 7 hours and 22 minutes in our practical Wi-Fi test. Thus, it does not last as long as the rest of our test field despite a 4,000 mAh battery. However, a better runtime can be achieved with a dynamic setting of the refresh rate by the system or a fixed value of 90 or 60 instead of 120 Hz.
The smartphone is fully recharged after about one and a half hours with the included charger.

Verdict - A lot of performance in a compact format
Asus delivers a very compact and high-quality smartphone with the Zenfone 8. The system performance is very good, which is also reflected in a very smooth operation in everyday use. Besides very fast Wi-Fi and a bright AMOLED display, the new 5G mobile standard is also supported.
The 256 GB storage in our test configuration can also leave the competition behind, whereas the OnePlus 9 and the Google Pixel 5 are also well positioned. If you want an even smaller device with similar performance, it is also worthwhile to go for the Apple iPhone 12 mini.
The Asus Zenfone 8 offers a lot of performance in a high-quality and compact casing.
Even in the 128 GB version of the Zenfone 8, the missing microSD card reader should not be a big annoyance. However, the missing DC dimming button in the settings menu will definitely be a criterion for exclusion for sensitive users. The battery runtime is also quite low with an activated 120 Hz refresh rate. However, a significant improvement can still be achieved here with a dynamic setting.
Price and availability
The Asus Zenfone 8 is available now, for example, on Amazon with 8 GB RAM and 128 GB storage for 669 Euro, 8 GB RAM and 256 GB storage for 729 Euro and 16 GB RAM and 256 GB storage for 799 Euros (~$813, $887 and $972 respectively).
