What the Experts Are Saying?

Given the current RAM crisis, the Realme C83 5G appears to be a solid budget 5G phone which ticks all the boxes without a load of compromises. It’s got a 144 Hz display, a massive battery and runs on Android 16. Yes, it could have featured faster charging, better storage speeds and cameras, but it is still easily one of the best phones under Rs 15,000.

The OnePlus N6x delivers all the essentials of a budget smartphone. The build quality is sturdy, and the 120 Hz display coupled with OxygenOS keeps the daily experience smooth. Its battery can comfortably push into a second day without needing you to hunt for a charger. While the cameras shine in daylight photos, the Camera app does need some optimisations. Overall, it remains a good pick if you want a phone for basic daily needs but also prioritise extended battery life.
