Pros and Cons

Final Verdict

The Realme C100x has the bigger battery, and if sheer endurance is your top priority, its 8000mAh cell is the main reason to look at it. The large 6.8-inch 120Hz display also makes it feel generous for the price, especially for video and casual browsing.

But as an overall phone, the Oppo A6s 4G looks like the safer buy. Its 8GB of RAM gives it a much better chance of staying smooth with multiple apps, social media, messaging, and lighter gaming, while the Qualcomm chipset is the more reassuring choice compared with the Realme’s Unisoc processor. The battery is still huge at 7000mAh, so you are not exactly sacrificing endurance.

Pick the Realme only if maximum battery life matters more than speed. For most people, the Oppo A6s 4G should feel faster, less limited, and more comfortable to live with day to day.
