Infinix has been releasing new phones at a pretty fast pace. We have recently seen new models in the Hot and Note series and now there is a new smartphone called the Infinix Zero 8i. The slightly amusing name aside, the Zero 8i packs some impressive specs on paper. You get a MediaTek Helio G90T processor, 8GB of RAM, a 90Hz refresh rate for the display, a quad 48-megapixel camera setup, and a starting price of just BDT 20,000. So do all of these specs translate to good real-world performance? To find out, we looked at the Infinix Zero 8i.

Infinix Zero 8i Design

The Infinix Zero 8i is a tall smartphone, and the large 6.85-inch screen makes one-handed use a bit fiddly. Getting to the top of the screen requires a quick hand movement. Infinix has opted for a dual selfie camera setup embedded in the top left corner. The Zero 8i is thin and has curved sides that make it easy to grip. The fingerprint scanner has been placed on the power button by Infinix, which is steadily becoming the trend these days, even for inexpensive smartphones. The position of the fingerprint scanner is convenient, but I can’t say the same for the volume buttons which are on the same side.

Infinix Zero 8i Dual Selfie Camera Gadgets Infinix Zero 8i 360 Review

The Infinix Zero 8i has a dual-camera setup for selfies

There’s a selfie flash towards the top of the screen, which is neatly hidden from view. I was only able to detect it when it was active. The SIM card tray is on the left side of the Zero 8i, while the top of the frame is bare. At the bottom, you have a USB Type-C port, a 3.5mm audio jack, and a speaker. Flip the phone over and the diamond-shaped camera module will catch your eye. This module is located in the center towards the top and is slightly raised, causing the smartphone to wobble when placed on a flat surface. Silver Diamond and Black Diamond are the two color options for the Zero 8i. Had the first one for this review and liked the matte finish on the back.

I found the Infinix Zero 8i to be a bit too heavy, tipping the scales at 210g. It packs a 4,500mAh battery which is below the average battery capacity you get at this price. The Infinix Zero 8i has a 33W rapid charging capability, yet it comes with an 18W charger.


Infinix Zero 8i Specifications

As I said at the beginning of the review, the Infinix Zero 8i spec sheet is quite interesting. You get a large 6.85-inch Full-HD+ display with a 20.5:9 aspect ratio and a fast 90Hz refresh rate. The display is set to 90Hz by default, but you have the option to change it to 60Hz or set it to Auto. Infinix chose the MediaTek Helio G90T processor, which is now a bit dated and was last seen with the likes of Redmi Note 8 Pro (Review) and Realme 6 (Review). What’s more intriguing is that it comes with 8GB of RAM and 128GB of UFS 2.1 storage from Infinix. The Helio G90T is a gaming processor, and Infinix claims that it has used liquid cooling to keep thermals in check. You get a triple-slot tray on the Infinix Zero 8i to accommodate two Nano-SIMs and a microSD card.

The Infinix Zero 8i includes a 4,500 mAh battery

The Zero 8i runs XOS 7 on top of Android 10 in terms of software. My unit had the October Android security patch which is out of date at this point. The user interface looks very familiar and I had no trouble finding my way around it. There is a game mode that disables auto-brightness and prevents the phone from switching between your data network and Wi-Fi to avoid issues. It also has an anti-gaming addiction feature that sends you a notification if you play for a long time. There is also a parental control setting that allows you to block any game after a certain period of time.

There is a fair amount of bloatware that comes pre-installed on the Infinix Zero 8i. I found some third-party games and apps, as well as the Infinix Theme app and an app called Palm Store that looks like an alternative to the Play Store. I found both of these apps to be spam as they kept sending suggestions.

Infinix Zero 8i Performance

The Infinix Zero 8i has a fast fingerprint scanner, and the device just needs a tap on the power button to unlock. Facial recognition was also fast, requiring no more than one attempt. The Zero 8i’s large screen makes for engaging content and I enjoyed streaming video on it. Stereo speakers would have enhanced the overall experience, but they aren’t available. I found the screen brightness to be adequate, but the surface is reflective. With the Zero 8i set to the faster 90Hz refresh rate by default, the UI felt snappy. It didn’t take long for apps to load, and multitasking was simple.

I ran benchmarks on the Infinix Zero 8i to see how it fared against some of the other smartphones available at the same price today. On AnTuTu, the phone achieved 289,887 points. In the single-core and multi-core tests of Geekbench 5, it received 529 and 1703 points, respectively. In GFXBench’s Manhattan 3.1 and Car Chase tests, the Zero 8i managed 26fps and 15fps, respectively.

Infinix Zero 8i Camera Module Gadgets Infinix Zero 8i 360 Review

The main back camera on the Infinix Zero 8i is 48 megapixels.

Call of Duty Mobile loaded quickly and ran on High settings by default for both graphics and frame rate, without any issues. I detected a 6% battery drain after 15 minutes of play, and just the top of the smartphone was barely warm to the touch. The Zero 8i handles gaming well, but a larger battery would have been better for people who intend to spend a lot of time playing games every day.

The Infinix Zero 8i offered decent battery life. I was able to get through a full day with my usage pattern and only needed to charge it the next day. In our HD video loop test, the phone was on for 16 hours and 45 minutes, which is acceptable given the battery capacity. The Zero 8i supports 33W fast charging, but only an 18W charger is included in the package. With this, the smartphone was charged to 33 percent in 30 minutes and reached 68 percent in an hour.


Infinix Zero 8i cameras

The Infinix Zero 8i has a quad-camera setup with a 48-megapixel main camera, an 8-megapixel ultra-wide camera, and a 2-megapixel depth sensor that Infinix calls a “bokeh lens,” and a low-light sensor. which is known as an “AI lens”. The ultra-wide-angle camera of the Infinix Zero 8i may be used to create macro photographs. For selfies, there’s a 16-megapixel main camera and an 8-megapixel ultra-wide camera. The camera app is simple and straightforward. I also found the AI ​​to be quick to spot any scene and set the phone up for it.

The Zero 8i produced average daylight shots. Nearby objects had decent detail, but the phone didn’t capture details on objects farther away well. Photos taken with the ultra-wide-angle camera had a slightly different color tone and also lacked detail. The camera app has distortion correction enabled by default, which is helpful.

The camera failed to focus where I wanted it to for close-up images on occasion. The photos looked good as-is, but enlarging them revealed that the output isn’t very sharp. Portraits were acceptable, with good edge detection. You have the option to set the level of blur before taking a photo. You can get higher resolution shots with the wide-angle camera than you can with the dedicated macro cameras on most phones, but the details are still strictly average.

Low-light shots were average and lacked detail. After enabling night mode, the quality improved, but it takes about four seconds to capture a shot and there was still visible grain when zooming in.

Low-light shots were average and lacked detail. After enabling night mode, the quality improved, but it takes about four seconds to capture a shot and there was still visible grain when zooming in.

Selfies taken with the front camera’s primary lens featured a lot of detail. The wide-angle selfie camera offers a wider field of view but doesn’t quite match the main one in terms of quality. You can also take portrait selfies, and I found the edge detection to be quite good. Low-light selfies were good, and the selfie light comes in handy when shooting in dimly lit areas. Video recording maxes out at 4K for the main front and rear cameras. Images shot in 4K weren’t stabilized, but 1080p video still had visible shakes. There’s an Ultra Steady mode that helps stabilize footage, but it had a visible glow effect in low light.

My opinion about Infinix zero 8i

The Infinix Zero 8i packs some interesting hardware that helps it deliver good performance. The MediaTek Helio G90T is a capable processor and coupled with 8GB of RAM, there’s very little that can slow it down. Even the 90Hz display contributes to a smooth overall user experience.

However, the Zero 8i has a couple of shortcomings that might make potential buyers think twice. The first has to be the software; there’s a lot of pre-installed bloatware and some of the standard apps send out spam notifications, which is disappointing. Battery capacity is decent, but if you’re a heavy user looking to play games frequently, this phone may need frequent changes. Finally, if you want better cameras and better battery life at this price point, you can take a look at the Realme 7 (Review) and the Redmi Note 9 Pro Max (Review) as possible alternatives.
