The Infinix Smart 20 is a budget phone, and the Infinix Smart 20 price in Bangladesh is BDT 14,999 for the 4GB/64GB model. It pairs a large 6.78-inch 120Hz display with a 5200mAh battery. In addition, it adds NFC, an IR blaster, FM radio, and the latest Android 16. However, it stays entry-level, with a basic 8MP camera and modest 15W charging. Read the full specifications, the price in Bangladesh, and our review below.
The Infinix Smart 20 is an entry-level smartphone with a surprisingly rich feature set. As a result, its main draws are a big 120Hz screen, a long-lasting battery, and extras like NFC and an IR blaster. In addition, it ships with the latest Android 16. However, it stays budget-focused, with a basic 8MP camera and only 4GB of RAM. Overall, it is a well-equipped daily phone that is held back mainly by its camera.
Design and Build
The Infinix Smart 20 has a slim, modern design at just 7.7 mm thick. It also carries an IP64 rating and military-grade drop resistance, so it is durable for the price. The front uses Gorilla Glass, while the back and frame are plastic. In addition, it comes in four colours: Shadow Black, Polaris Titanium, Sunlike Orange, and Cloudline Blue.
A 6.78-inch 120Hz Display
The Infinix Smart 20 has a large 6.78-inch IPS LCD display with a smooth 120Hz refresh rate and a 240Hz touch sampling rate. It also reaches 700 nits in bright mode and adds Always-On and Dynamic Bar features. As a result, scrolling feels fluid and the screen stays readable outdoors. However, the resolution is only HD+ (720 x 1576), so fine detail looks soft. Still, the big, smooth screen is great for daily use.
Performance and Helio G81 Ultimate
The Infinix Smart 20 runs on the 12nm MediaTek Helio G81 Ultimate chip with the Mali-G52 GPU. It pairs this with 4GB of RAM and 64GB of storage, plus microSD support up to 2TB. As a result, it handles daily apps, social media, and light gaming well. However, with only 4GB of RAM, heavy multitasking is limited. For a similar Infinix, see the Infinix Smart 8 Pro.
8MP Camera
The Infinix Smart 20 has a single 8MP rear camera with a dual-LED flash, plus an 8MP selfie camera. In good light, both cameras can take simple snapshots, and they record video up to 2K resolution. However, the 8MP resolution is modest, so photos lack detail and low-light results are weak. As a result, the camera is the phone’s clearest weak point.
5200mAh Battery
The Infinix Smart 20 packs a 5200mAh battery. As a result, it easily lasts a full day of normal use, and often longer with light use. It also supports 5W reverse charging to top up small accessories. However, charging is modest at 15W, so a full top-up takes a while. Still, for endurance, the battery is dependable.
Software, Connectivity, and Security
The Infinix Smart 20 ships with XOS 16, based on the latest Android 16. For connections, you get 4G, dual SIM, NFC, and Bluetooth. It also keeps an IR blaster, FM radio, a 3.5mm jack, DTS-tuned audio, and a USB-C port. However, there is no 5G. A side-mounted fingerprint sensor and face unlock handle security. For full details, see the official Infinix Smart 20 page or the official Infinix website.

Infinix Smart 20 vs Xiaomi Redmi 13C
At this price, the Xiaomi Redmi 13C is a close rival. The Redmi 13C offers a much higher-resolution main camera, which is its main advantage. However, the Infinix Smart 20 answers with the latest Android 16, NFC, an IR blaster, and FM radio. So the Smart 20 is the better pick for features, while the Redmi 13C wins on camera. Choose based on what you value more.
Should You Buy the Infinix Smart 20?
The Infinix Smart 20 makes sense if you want a big 120Hz screen, long battery life, and rich features like NFC and an IR blaster on a budget. You also get the latest Android 16 and a durable IP64 body. However, the trade-offs are real. For example, the camera is only 8MP, the RAM is just 4GB, and charging is slow. For a better camera, the Infinix Hot 40i is worth a look. Overall, the Smart 20 suits feature-focused buyers more than photographers.

Infinix Smart 20 Rating Explained — How We Scored It
We rate every phone across eight areas on a 1–10 scale. Our scores come from real-world use and reviews. We then average them for the overall result. As a result, the Infinix Smart 20 earns an overall 5.3/10. Here is how each area scored, and why.
Design – 6/10
The slim 7.7mm profile, IP64 rating, military-grade drop resistance, and Gorilla Glass front make this a well-built budget phone. Four colour options add choice. The plastic back and frame are the only real reminders of the price.
Display – 5/10
The large 6.78-inch screen runs at a smooth 120Hz, hits 700 nits, and adds Always-On and Dynamic Bar features. However, the HD+ (720 x 1576) resolution is low, so fine detail and text look soft.
Performance – 4/10
The Helio G81 Ultimate is a capable budget chip for daily tasks and light gaming. However, the Smart 20 pairs it with just 4GB of RAM, so heavy multitasking and demanding apps feel limited next to better-equipped rivals.
Camera – 3/10
The single 8MP rear camera and 8MP selfie can manage basic snapshots in good light, and 2K video is a nice touch. However, 8MP is very low for this price, so detail is limited and low-light results are weak. This is the phone’s main weakness.
Connectivity – 7/10
This is a real strength. You get NFC, an IR blaster, FM radio, and a 3.5mm jack, alongside dual-SIM 4G, Wi-Fi 5, Bluetooth, USB-C, and multi-system GPS. Only the lack of 5G holds it back at all.
Features – 6/10
IP64 protection, military-grade drop resistance, DTS-tuned audio, microSD up to 2TB, reverse charging, and the latest Android 16 make a rich package. The modest charging and basic camera are the main gaps.
Battery – 6/10
The 5200mAh battery comfortably lasts a full day, and the phone adds 5W reverse charging. However, charging is modest at just 15W, so topping up takes a while, which keeps the score from going higher.
Usability – 5/10
The 120Hz screen, latest Android 16, big battery, and rich features make daily use convenient. However, the 4GB of RAM, basic 8MP camera, and slow charging are the main limits for everyday users.
In short, the Infinix Smart 20 is a feature-rich budget phone with a big 120Hz screen, NFC, an IR blaster, a durable IP64 body, and the latest Android 16. The main compromises are the basic 8MP camera, the 4GB of RAM, and the slow 15W charging. However, for buyers who value features and battery life over photography, it delivers.
