Infinix Smart 4 Plus Review

Infinix is a budget smartphone brand that makes decent phones for the price they offer. Their latest integration is the Infinix Smart 4 Plus smartphone which is a successor to the Infinix Smart 3 Plus. Is this budget offering from Infinix better than the ones from other competitive brands? Let’s find out. Here’s our Infinix Smart 4 Plus Review.

Build & Specifications

The Infinix Smart 4 Plus has a 2.5D glass back with is this neat gem-cut pattern on the rear panel. On the front is a 6.82-inch HD+ Display(720×1640) paired along with a waterdrop notch same as we have seen on some other smartphones in the past couple of years. This notch also houses the 8MP front-facing camera along with the speaker grill on top.

The screen has an aspect ratio of 20.5:9 which makes the phone pretty wide. Also, the narrow bezel gives it a 90.5% screen to body ratio. Moving to the internals, the phone is powered by a MediaTek Helio A25 12nm processor housing 8 cores. The processor is paired with an IMG PowerVR GE8320 GPU to handle all the apps and a bit of gaming. The phone handles your daily dose of social media, messaging and some other low graphic games pretty well.

The Smart 4 Plus comes paired with 3GB of RAM along with 32GB of internal storage which can be expanded up to 256GB via the Micro-SD card slot. Infinix has no other storage or RAM option and this is the only one you get. Speaking of card slots, the Infinix Smart 4 Plus gets a 3-in-one card slot which has an individual slot for the SD card.


The Infinix Smart 4 Plus comes with XOS 6.2 based on Android 10. This skin of Android has many features up its sleeve. The huge 6000maH battery can go all day without a break. The claimed screen on time for video playback is 23 hours with 15hrs of gaming which is quite impressive for what the phone is priced at.

The MediaTek Helio A25 is an Octa-Core processor that is clocked at 1.8Ghz and can handle most of the apps that are thrown at it. It can easily run daily social networking apps like Instagram, Snapchat, etc. Gaming might be an issue here because of the small RAM of 3GB and the IMG PowerVR GE8320 GPU. The brand Infinix is known for its battery, and this one has got a massive 6000Mah battery which lasts a full day for sure. It can also handle some light gaming as well. We tried old school games such as Subway Surfers, Angry Birds, Temple Run and more; all these games performed fairly well and the smartphone can handle quite some gaming.

The phone has some software features up its sleeve to save battery with the smart power saving for up to 3 days. The software experience is just fine and the XOS comes with a lot of bloatware that hinders the performance. The phone also comes with a DTS-HD Cinematic sound experience. You can even customize the sound preferences using an equalizer, although the sound quality is mediocre. This is a great addon at the price segment and it actually makes a difference.

For security, the phone comes with an optical Fingerprint scanner placed on the back panel of the phone which is more ergonomic. It has also got a 0.3-sec face to unlock using the front camera and software. The phone also supports dual sim 4G VoLTE and also VoWi-Fi which is a great feature to have.


Talking about the cameras, it is powered by a 13MP AI Dual Camera setup to capture every detail. The camera is a 13MP sensor with an aperture of f/1.8 along with a Depth sensor of f/2.0 aperture.

Moving to the front of the phone, it packs an 8MP sensor with an aperture of f/2.0 along with a dedicated flash for those night selfies of yours. The camera can go a bit wider with the software.

Some of the modes the main camera includes are AI HDR mode for High Dynamic Range photos, Auto scene detection like food, street, nature, night portrait. The cameras are average and can do the job and nothing more than that. The overall camera performance is just fine in daylight conditions and the camera struggles in low light conditions.

Here are some of the camera samples:


So, the Infinix Smart 4 Plus is a great budget smartphone overall. It does the job as a daily driver. The software features make up for a good experience and the battery life is also on par with some of the other smartphones in this segment. The cameras are decent and can take some decent shots in bright day light considering the phone is available for around ₹8000.

The build quality is decent enough and in no way. The charging speeds are also quite decent, and the humongous 6000mAh battery that lasts about 2 days with an average screen on time of about 5-6hrs on a full charge. If you have to purchase a budget smartphone and do not want a hole in your wallet, this would be a nice pick.

Overall, Infinix Smart 4 Plus is a great phone in the entry-level segment with a huge 6000mAh battery and big screen, its camera performs decently too but if you are into gaming and performance is your only concern then there are better options in the market.
