In a world where phone displays keep getting bigger, Asus Zenfone 8 is a lot different from other similarly priced devices. The phone delivers a great experience while also being compact. This is a great choice for people who want powerful compact phones. The phone measures 5.83 inches in height, 2.70 in width, and 0.35 inches in thickness. It has a 5.9-inch Super AMOLED screen that can go up to 1100 nits of brightness. Besides, the phone has a screen-to-body ratio of 82.9% and a PPI density of 446.

As you might have guessed, the multimedia experience is great even if you are outdoors. The presence of high-resolution audio and stereo speakers further improves your multimedia experience. The weight of the device is 169 grams, for which the company should be credited. The build quality of the phone is pretty awesome as it has an aluminum frame. Additionally, the glass back is protected by Gorilla Glass 3, while the glass front is protected by the top-of-the-line Gorilla Glass Victus. The phone has an IP68 rating for dust and water resistance.

What’s also top-of-the-line is the processor used in this phone. Qualcomm SM8350 Snapdragon 888 5G handles the overall performance of Asus Zenfone 8. On the other hand, the Adreno 660 GPU handles the gaming performance of the phone. The 120 Hz refresh rate further smoothens visuals while playing or scrolling. On the software side, the phone runs Android 11 out of the box with ZenUI 8 on top. Asus has promised two years of updates for the phone. It should have been at least 3 years, considering the competition and the fact that the phone belongs to the high-end segment.

Asus Zenfone 8 comes in five configurations. The base variant has 6 GB RAM with 128 GB of internal storage. The other variants have 8 GB RAM with 128 GB ROM, 8 GB RAM with 256 GB ROM, 12 GB RAM with 256 GB ROM, and 16 GB RAM with 256 GB ROM. For color, you get to choose between Obsidian Black and Horizon Silver. The price of the phone starts at ₹44,190 or approximately $593. The device doesn’t allow you to expand its memory. However, seeing how each variant has at least 128 GB of storage, it should be fine.

Coming to sensors, it has an under-display fingerprint sensor, accelerometer, gyro, proximity, and compass. Moving on to camera performance, the phone has a dual-camera setup on the back. It has a 64 MP wide-angle camera and a 12 MP ultrawide camera. The camera has all the usual features like LED flash, HDR, and panorama. The rear camera setup can record videos in 8K, 4K, 1080p, and 720p. The 12 MP selfie camera, on the other hand, can record videos in 4K and 1080p. The camera performance, on the whole, is merely decent.

As far as the battery backup is concerned, the Asus Zenfone 8 should last you for a day on a full charge. However, it won’t last more than a day for most users. The phone has a 4000 mAh lithium polymer non-removable battery. This is one of the rare disadvantages of owning this device. On the bright side, it supports reverse charging, USB Power Delivery 3.0, and 30W fast charging. Also, the device can get to 60% charge in 25 minutes and 100% charge in 80 minutes. For communication, it has USB Type-C 2.0, USB On-The-Go, GPS, Bluetooth 5.2, dual-band Wi-Fi, Wi-Fi Direct, and a hotspot. It also has support for Radio and NFC.
