Following the tradition of the Infinix Smart series, the newly unveiled Smart 20 HD enters the market as an accessible, entry-level Android phone designed specifically for budget-conscious users. You might notice that this phone shares its name with the Infinix Smart 20 released a few months ago. Beyond the naming convention, the new device inherits much of the earlier model's general layout and overall design language.

However, a closer examination reveals key hardware compromises on this newer device. The phone features a smaller screen, a less capable chipset, reduced memory, and older software. Ultimately, the Infinix Smart 20 HD is essentially a stripped-down variant of the standard model, It is designed to shave off a few extra dollars for anyone who needs a smartphone at the lowest possible price.

 

NOTE: Aside from a redesigned rear camera module, the Infinix Smart 20 HD is virtually identical to last year's Infinix Smart 10 in both design and specification. In short, both of them have the same model number-X6725.

DESIGN
From a visual standpoint, you’d be hard-pressed to tell the Smart 20 HD apart from the regular Smart 20. Despite sporting a slightly smaller 6.67-inch display compared to the 6.75-inch panel on the standard model, it retains the exact same sleek design: a centered hole-punch cutout for the selfie camera, an identical rear camera module, and a slim profile. Build quality remains uncompromised as well, matching the original model's solid construction and keeping an IP64 rating for dust tightness and splash resistance. Infinix didn't cheap out on the convenience features here either—you still get the dual speaker, IR blaster, and identical port layout found on the pricier model.

Talking about the Smart 20 HD's ports layout. The power button (which integrates a fingerprint reader) and volume keys are on the right side. The left side holds the 3-in-1 4G SIM tray. At the bottom, you find a USB Type-C port, a speaker, and a microphone. The secondary speaker is the only thing on the top side.

DISPLAY
Despite the minor reduction in size, the 6.67-inch display of the Smart 20 HD retains the 720p resolution of the standard model and typical entry-level smartphones. Specifically, The screen utilizes a 1600 × 720 pixel resolution at a density of 263 ppi. Because it operates within the same resolution tier, display sharpness and overall colour reproduction remain practically identical to its sibling—proving decent for casual media consumption and web browsing. Visual quality is standard for the class and won't leave you overly impressed, but it gets the job done.

Furthermore, the Smart 20 HD matches the respectable peak brightness of the regular Smart 20, topping out at 700 nits. This output is reliable for most indoor lighting conditions and well-lit environments. While the panel remains functional outdoors thanks to this brightness level, you will still need to squint when navigating under direct sunlight.

CAMERA
The camera setup is certainly not a strong suit of the Smart 20 HD. While the phone retains the 8MP front-facing camera from the regular Smart 20, it steps down to an 8MP main rear sensor (compared to the 13MP sensor on the regular counterpart). Although the device manages to capture acceptable photos, particularly in well-lit environments, overall image quality remains typical of the budget tier: fine for everyday snapshots, but hardly suitable for content creators or selfie enthusiasts.

Surprisingly, the phone redeems itself in the video department. Despite the lower-resolution main sensor, both the front and rear cameras can capture video up to 2K resolution. That is a rare perk for this price segment, where most competitors—even those sporting higher-megapixel main cameras—are limited to standard 1080p recording.

PERFORMANCE & SOFTWARE
My primary complaint regarding the Infinix Smart 20 HD centres on its software package. The device ships with Android 15, which represents a disappointing step backward from the Android 16 software found on the regular model. This frustration is compounded by the complete lack of assurance regarding future OS upgrades from the manufacturer, especially at a time when new phones are already starting to ship with Android 17.

On the hardware side, the Infinix Smart 20 HD is powered by a Unisoc T7250 chipset. While this processor is generally considered a step down from the MediaTek Helio G81 inside the standard model, real-world performance remains surprisingly close. Furthermore, because nearly all competing devices in this budget segment rely on the same T7250 silicon, the processing experience is very much par for the course—delivering decent, manageable day-to-day performance typical of entry-level hardware.

However, long-term speed and multitasking capabilities may hit bottlenecks due to memory constraints. The Smart 20 HD comes equipped with 3GB of RAM. Unfortunately, i haven't seen the 4GB RAM variant of this phone, unlike the regular model. The Smart 20 HD's 3GB allocation is paired with a modest 64GB of internal storage. On the bright side, users retain the flexibility to expand storage up to 2TB via a dedicated micro-SD card slot.
 

BATTERY

While the standard Infinix Smart 20 features a slightly larger 5,200mAh battery, the Smart 20 HD steps down to a regular 5,000mAh capacity. Despite this slight reduction in size, the HD model retains the exact same 15W charging speed as its regular counterpart.

Infinix conveniently includes the necessary 15W power adapter right in the box. In real-world testing, topping up the battery from a completely depleted zero percent to full capacity takes just over two hours and fifteen minutes.
