Smartphone Buying Guide for Bangladesh: What Really Matters

Spec sheets are long, and every phone claims to be the best. The trick is to decide what you use the phone for, then spend your money on the parts that matter for that.

1. Start with how you use your phone

• Calls, Facebook, YouTube: almost any modern phone works. Focus on battery and a good screen.
• Gaming: the chipset and cooling matter most, then a high refresh rate display.
• Photos and video: camera processing and stabilisation matter more than megapixels.
• Work and study: storage, battery life and long software support.

2. Chipset: the engine

The chipset (Snapdragon, Dimensity, Exynos, Apple A-series, Helio, Unisoc) decides speed, battery efficiency and camera processing. Two phones with the same RAM can feel very different because of the chipset. Look up independent reviews of the chipset rather than trusting core counts or clock speed.

3. RAM and storage

• RAM: 6–8 GB is comfortable for most people today. Gamers and heavy multitaskers benefit from more.
• Storage: photos, videos and apps fill phones quickly. 128 GB is a sensible minimum; choose 256 GB if you record a lot of video. Check whether the phone has a memory card slot.
• "Virtual RAM" or "extended RAM" uses storage space and is not the same as real RAM.

4. Display

AMOLED panels give deeper blacks and usually better outdoor visibility; good LCD panels are still fine. A 90 or 120 Hz refresh rate makes scrolling smoother. Brightness matters if you use the phone outside a lot.

5. Battery and charging

A 5000 mAh battery is common and lasts a full day for most users. Charging speed is listed in watts. The charger in the box matters too: some brands no longer include one. See our charger and cable guide if you need to buy one.

6. Camera: look beyond megapixels

A 50 MP main camera with good processing beats a 108 MP camera with poor processing. Optical image stabilisation (OIS) helps in low light and video. Extra 2 MP "macro" or "depth" lenses add little.

7. Software updates

Check how many years of Android (or iOS) and security updates the brand promises. Longer support keeps the phone safe and useful for longer.

8. Official or unofficial

This affects your warranty and whether the IMEI is registered. Read our guide on how to check an official phone before you buy.
