7 Crucial Things to Know Before Buying a Mobile Phone – Avoid These Mistakes

Thinking of buying a new smartphone but unsure what to check first? This is where most people go wrong. Choosing the wrong phone can cost you both money and peace of mind. This article will walk you through all the essential things you need to know to make a wise purchase decision.

Smartphone Buying Guide: What to Check First

Not following a proper smartphone buying guide may result in both dissatisfaction and wasted money. The first thing to examine is the processor. If you enjoy gaming or video editing, opt for phones with Qualcomm Snapdragon or MediaTek Dimensity chipsets.

Next, consider RAM and Storage. For everyday use, 6GB RAM and 128GB storage are sufficient. However, if you multitask heavily, go for 8GB RAM.

The third factor is the display. AMOLED displays offer vibrant colors and lower battery consumption. If the refresh rate is 90Hz or 120Hz, scrolling becomes much smoother.

The fourth important aspect is the camera. Don’t just go by megapixels; the sensor quality matters. Sony or Samsung sensors usually ensure better photography.

Fifth, focus on the battery and charging. A battery of at least 5000mAh with 33W or higher fast charging is ideal for modern usage.

Sixth, ensure the operating system and update policy are reliable. Android 14 or iOS 17 is recommended, along with 2–3 years of security updates.

Lastly, evaluate the brand and after-sales service. Brands like Xiaomi, Samsung, Realme, and Vivo typically have service centers across Bangladesh.

Mistakes to Avoid When Following a Smartphone Buying Guide

Many people buy phones just for looks. This is a major mistake. Similarly, getting swayed by discounts can also lead to poor choices.

• Don’t skip online reviews: Check platforms like YouTube and trusted sites like GSMArena.
• Buy future-proof phones: Features like 5G support and software updates ensure longevity.
• Don’t buy budget phones for heavy usage: Such phones may lag during gaming or multitasking.

By avoiding these mistakes, you can enjoy a hassle-free experience and won’t need to upgrade your phone frequently.

Budget Recommendations for Smartphone Buyers

People often think it’s hard to find a good phone under 20,000 BDT. That’s not true anymore. With proper research, you can find great value even in this price range.

• 📱 15,000–20,000 BDT: Xiaomi Redmi 13C, Realme Narzo series
• 📱 25,000–30,000 BDT: Samsung Galaxy M14, Infinix Zero 30
• 📱 30,000–40,000 BDT: OnePlus Nord CE3 Lite, iQOO Z7

Which Brands Are Trustworthy? A Service-Based Evaluation

Samsung and Xiaomi usually offer great updates and after-sales support. Apple’s iPhones are best in quality, but the price can be a barrier. Newer brands like Tecno or Itel offer good value but may lack strong service networks.

Where to Research Before Buying a Phone?

These resources can help:

• GSMArena – for specs and detailed reviews
• Bangladeshi YouTubers like “Tech Bangla” and “Gadget BD” – for real-life experience
• Online forums such as Reddit and Facebook Groups – for user opinions

Following a proper smartphone buying guide ensures you get the best device for your needs and budget, reducing the chances of buyer’s remorse.
