Infinix Smart 20

Infinix Smart 20 Price in Bangladesh

Proof that a genuinely large, smooth-scrolling display doesn't need to cost much: the Infinix Smart 20 pairs a 6.78" 120Hz display with a reliable 5200mAh battery, all in a phone priced from 14,999. Whether you're buying your first smartphone, picking one out for a student, or just want a dependable everyday device, this is a strong budget pick worth a closer look.

Official vs Unofficial BD Market Price Comparison — Variant-wise

The Infinix Smart 20 is sold in Bangladesh through the unofficial import channel—like most of SMS Gadget's phone lineup, it's a genuine, brand-new unit brought in outside Infinix's official Bangladesh distribution, so the warranty comes from the retailer rather than from Infinix's own manufacturer warranty program.

This price range sits fairly tight compared to some other budget phones in Bangladesh, a good trust signal, since it means the phone isn't being priced wildly differently across sellers. Always check the live listing for the most current number, since prices do get revised periodically.

Warranty: SMS Gadget backs the Infinix Smart 20 with its own 10-day replacement guarantee and 2-year service warranty — solid retailer-level after-sales cover, though it's worth confirming exactly what's included (screen, battery, charging port) since it isn't backed by Infinix's manufacturer warranty.

EMI: EMI options are available through SMS Gadget, so if you'd rather not pay the full amount upfront, you can spread the cost across monthly installments.

Infinix Smart 20 Specifications

Display

A 6.78" IPS LCD panel with an adaptive refresh rate up to 120Hz, HD+ resolution (1576 x 720), a 90% screen-to-body ratio, and peak brightness up to 700 nits. In everyday use, that combination makes for smooth scrolling through videos and social feeds, a genuinely large, fluid screen for the price. Worth being upfront about: this is HD+ resolution, not FHD+, which is a fair trade-off most budget phones make at this price point.

Design & Build

At just 7.7mm thick, the Smart 20 stays impressively slim despite its large display, giving it a comfortable, modern in-hand feel rather than the bulky footprint you'd expect from a big-screen budget phone. It has a Gorilla Glass front with a plastic back and frame, plus IP64 splash resistance—practical protection against accidental spills, sudden rain, or a splash while commuting.

Color Variants

Shadow Black, Polaris Titanium, Sunlike Orange, and Cloudline Blue.

Storage Options

4GB RAM (expandable up to 8GB via virtual RAM) with 64GB or 128GB internal storage, plus a dedicated microSD slot supporting expansion up to 2TB — plenty of room to grow into.

Camera

An 8MP main camera paired with an 8MP selfie camera, backed by AI Cam, Portrait, Night, and Panorama modes. Worth being honest here: this is a simple single-lens setup rather than a multi-camera array, so it's best suited for casual everyday photos and video calls rather than serious photography, a reasonable trade-off given the phone's focus on display and battery.

Battery

A 5200mAh battery keeps this phone running comfortably through a full day of calls, browsing, and social media, backed by an efficient chipset that helps stretch that further. Charging comes via a 10W charger in the box (with 15W charging supported), plus 5W reverse charging, modest speeds, but functional enough to top up a smaller device like earbuds in a pinch.

Chip

MediaTek Helio G81 Ultimate (12nm), an octa-core chip that handles calls, social media, browsing, and light gaming efficiently without unnecessary lag.

Software

Android 16 with XOS 16 on top, a side-mounted fingerprint sensor, FM radio, DTS-tuned audio, and a 3.5mm headphone jack, a solid, well-rounded feature set for a budget phone. Note that this model does not include NFC, so if contactless payments are important to you, that's worth keeping in mind.

Frequently Asked Questions

1. What is the price of the Infinix Smart 20 in Bangladesh? 

The Infinix Smart 20 is priced at 14,999 for the 4GB/64GB variant at SMS Gadget, with a 4GB/128GB option also available. Confirm the current price for that configuration directly with the retailer, since pricing can be revised periodically.

2. How long does the 5200mAh battery actually last? 

For everyday use—messaging, browsing, and occasional streaming, the 5200mAh battery comfortably gets you through a full day. Heavier use like gaming or constant video streaming will bring that down faster, so actual runtime depends a lot on how you use the phone.

3. Does the Infinix Smart 20 support 5G in Bangladesh? 

No, this model supports 2G, 3G, and 4G networks, but not 5G. If 5G is a priority for you, you'll want to look at a different model in Infinix's lineup, or elsewhere in the budget segment.

4. Is the Infinix Smart 20 water and splash resistant? 

Yes, it carries an IP64 rating, meaning it's protected against dust and water splashing from any direction, enough to handle rain while commuting or an accidental spill, though it's not built for submersion.

5. Is 4GB RAM enough for everyday use on this phone? 

For everyday tasks, calling, messaging, browsing, social media, and light gaming, 4GB RAM (with virtual RAM expansion up to 8GB) handles things smoothly on the efficient Helio G81 Ultimate chipset. It's not built for heavy multitasking or resource-intensive games, but for its intended use case as an everyday essentials phone, it performs reliably.
