Start by focusing on three key points: RAM capacity, the operating system, and the screen. In this category, you’ll find options with 128 GB storage and 4 GB RAM, support for 4G LTE, and large displays around 6.6 to 6.74 inches. The configuration also includes a strong battery of about 6500 mAh, and sometimes a Dual SIM option.

Choose the phone that gives you a good balance between performance and battery life for your routine use.

Test your Wi‑Fi internet speed as well to evaluate stability and everyday browsing performance.
