Infinix Zero 4 Plus Review: Almost Perfect

After a little over a week of throwing everything at it, I sat down to write this Infinix Zero 4 Plus review and found myself looking for one bad thing to say about this big phone. Did I eventually find one? You will have to read to the end to find out. But the Zero 4 Plus will hold a pivotal point in history. It is Infinix’s first premium flagship, and we were interested in finding out how well it pulls it off. Come with me.

If you have not seen them already, you should have a look at some of the informative articles we already have published on the Infinix Zero 4 Plus:

Infinix Zero 4 Plus Review: Quick Pros And Cons

Before we dive into the review proper, starting with the major pros and cons of this device.

Key Features Cons
Beautiful design and solid, premium build Sometimes, it gets pretty hot during charging while there’s an active 4G connection.
Big, crisp 5.98-inch display is great for reading, editing, viewing photos and watching videos.
4G LTE support for all 4G mobile networks in Nigeria
It lets you peg network mode any way you like it
XOS Chameleon is light and breezy
Solid battery life

Infinix Zero 4 Plus Review: Hardware/Design

The black unit of the Zero 4 Plus is eye candy. It has design lines that remind me of the beautiful UMi Plus. The screen has the same 2.5D curved glass and smoothness too. The aluminum body is well crafted and feels good in the hands. It is a solid smartphone in the hand. It is big though, and if you are clumsy with large phones, you will be uncomfortable with the Zero 4 Plus.

At the back of the Zero 4 Plus is a 21 megapixel camera with laser autofocus and dual LED flash. On the left hand side is the eject-able dual-SIM compartment. One of the slots can also take a microSD card. On the right side we have the volume rockers and the power/lock button.

The Zero 4 Plus has two loudspeaker grills that sit astride the regular USB port at the bottom edge, while the 3.5 mm audio jack port sits at the top.

Infinix Zero 4 Plus Review: Software

The Infinix Zero 4 Plus runs a customised version of Android 6 Marshmallow called XOS Chameleon. XOS is what Infinix named their custom user interface. It is light and breezy and includes all sorts of nifty tools. Some include the ability to block numbers for calls and SMS. The drop-down menu also gives the user direct access to several useful features, including toggling ultra power mode, high performance mode, do not disturb, screen recording, cast and scrollshot, among others.

I like XOS Chameleon. The big question is whether or not Infinix will provide an update to push Android 7 Nougat to the Zero 4 Plus. This is a flagship smartphone after all.

Infinix Zero 4 Plus Review: Network, Telephony

Telephony on the Infinix Zero 4 Plus is of very good quality. Callers at the other end also notice the superb quality too.

The Infinix Zero 4 Plus works with 4G LTE networks from Glo, MTN, Etisalat, Smile, Ntel, Swift and Spectranet. It is one of the exclusive smartphones that provides that level of 4G compatibility.

True to form, XOS tweaks means that the user can easily peg network mode to 4G only. As such, the phone will cycle through 2G, 3G and 4G as network conditions dictate. There are also 3G only and 2G only modes.

Infinix Zero 4 Plus Review: Display and Multimedia

The Zero 4 Plus has a 5.98-inch 2.5D curved display. Can we just call this a 6-inch display? Typing out 5.98 every time is a pain. Thanks. As far as I can tell, this is the very first time too that Infinix has Gorilla Glass on any of their smartphones. And it makes a difference in the feel of the glass when you touch it. Good one.

One niggle of the display is the lack of automatic brightness adjustment. You have to manually set a brightness level and manually adjust it whenever you need more or less brightness.

The quality of audio from the loudspeaker betrays the dual speaker grills at the bottom end of the phone. This is no stereo speaker. Audio is good and loud. Just not mind-blowing. However, plugging in the included headset provides you with very good music experience.

Infinix Zero 4 Plus Review: Photography

The Infinix Zero 4 Plus has a 21 megapixel rear camera with laser auto-focus and dual LED flash. On the front, it has a 13 megapixel snapper for selfies. We put them to the test.

Below are some sample photographs that we took with the Zero 4 Plus cameras:

For comparison purpose, here is a shootout between the main cameras of the Zero 4 Plus and the Lumia 950:

Zero 4 Plus versus Lumia 950

The picture at the top is from the Zero 4 Plus. Note how the Lumia 950 does a better job at lighting both the object and the environment. Still, the Zero 4 Plus camera does a good job with its dual LED flash.

In poor lighting, the main camera tends to take a brief while to focus. I expected the laser auto-focus to produce faster focus times. The 20.7 megapixel camera takes good photographs but it isn’t up among the greatest et. The selfie camera has a proper flash (not soft flash), which is quite good.

Among devices in its class, though, the two cameras of the Infinix Zero 4 Plus are among the best we have seen around here. Taking photos gets more fun and convenient with the use of the Fingerprint scanner. This makes up for the lack of a hardware shutter button. Cool stuff.

Infinix Zero 4 Plus Review: Multitasking/Performance

Multi-tasking on the Zero 4 Plus is a smooth experience. It should be. Any smartphone with 4 GB RAM and a 2.1 GHz Helio X20 processor shouldn’t be groaning when switching between tasks or handling heavy tasks.

In the benchmark tests we ran, the Zero 4 Plus came up with an AnTuTu score of 84,799. That is a very good result. You can see the rest of our benchmark test results HERE.

Infinix Zero 4 Plus Review: Battery life

With a 4,000 mAh battery, the Zero 4 Plus has impressive battery life. All through the review period, I left the charger at home and used the phone all day – sometimes till 10 pm – without running out of power. Note that I had an active 4G connection on most of the time. This is a charge-up-and-forget-about-power phone. And with fast charge built in, battery performance and charging are strong points of this beautiful device.

Infinix Zero 4 Plus Review: Final Words

After two weeks of using the Infinix Zero 4 Plus on a daily basis, my verdict is that it is a solid flagship that is hard to beat at its price point. Infinix’s first premium flagship is a big winner and highly recommended by us at Mobility Arena. There is no word yet from Infinix about a software upgrade to put Android 7 Nougat on it. We can only hope.

    Brilliant review ! A phone to go for, but recession is not our friend

    As far as I can tell, this is the very first time too that Infinix has Gorilla Glass on any of their smartphones

    Smashing! A smashing phone you wouldn’t care to smash just to test out this Gorilla hype

    InfiniX has sure “chopped up”

    True to form, XOS tweaks means that the user can easily peg network mode to 4G only. As such, the phone will cycle through 2G, 3G and 4G as network conditions dictate.

    If you have pegged , why would it cycle.? I thought that cycling option is the 4G/3G/2G?

    One niggle of the display is the lack of automatic brightness adjustment. You have to manually set a brightness level and manually adjust it whenever you need more or less brightness.

    I handle this kind of scenario with AutomaGic for Android .

    Step out into the sun, disolay gets turned up to a preset brightness level by turning the phone upside down. Do it again, and it comes back to previous level.

    Bravo, InfiniX.

    Nice review. Definitely planning to get this phone to replace my ZenFone 2. One question though: Is the screen IPS LCD or AMOLED? Thanks.

    A mouth watering proposition of a Flagship, wish Infinix could have tried AMOLED screens,could have made it a complete piece of work..

    Anyway the phone has automatic brightness, good battery, support all the 4g networks, fair enough display and camera, fast charging is very good, can be peg to 4g only (rare in most phone)….. With all these good features I think the phone has a bad software, XOS will display advert indirectly, if you are coming from iOS or Samsung you’ll hate the notification it works and it doesn’t work no matter how you do the setting especially yahoo mail, sometimes most applications will not push unless you click on it or unless you are using the phone this includes WhatsApp and bbm if the phone is in idle you may be on your own. Multi account does not push notifications from the second account unless you click on it, this is 2017 flagship phone are not expected to be heating the heating is not seriously bad anyway, to change your wallpaper and lock screen together needed to be learnt if you don’t use the XOS, in all Infinix Zero 4 plus is a good phone that need a software upgrade. Please note that I have this phone now for 4 weeks.

    Nice Job bro, very happy seeing this kind of detailed review in Nigeria, I must confess you are doing a nice job. However, I am planning to upgrade soon and am not willing to buy a very large device, please do a comparison between this monster and it’s younger brother (Zero 4). Thanks ones again for the good work.

    Very useful review,
    Covered almost every part and that indeed help us to make final decision about buying this beast.
    I was only worried about the camera bump at the back because it may damage the rear camera lens but anyways it still stands a strong contender in this price range.
    👍
