Nokia C12 Plus

  • Clean, near-stock Android experience
  • Simple and easy-to-use interface
  • Potentially longer software support (Nokia's reputation)

  • Significantly weaker processor
  • Extremely slow charging speeds
  • Limited performance for demanding apps

Realme C51s

  • Faster and more capable Unisoc T612 chipset
  • 33W fast charging for quick top-ups
  • Larger display for a more immersive experience

  • Potentially more bloatware (Realme's history)
  • Software updates may be less frequent
  • Camera performance likely similar to Nokia

Display Comparison

Neither device boasts a standout display. Both likely utilize LCD panels, common in this price bracket. The Realme C51s doesn't specify resolution, but the Nokia C12 Plus has a 720x1600 resolution. The Realme's larger size (6.56” vs 6.3”) offers a more immersive experience. However, without brightness data, it’s difficult to assess outdoor visibility. Color accuracy is likely similar on both, leaning towards the basic side.

Camera Comparison

Camera performance is likely to be similar, with both phones focusing on basic photography. Neither device’s specifications suggest advanced features like OIS or particularly large sensors. The Realme C51s’s camera setup is unspecified, but the Nokia C12 Plus features a single 8MP rear camera. Image quality will be adequate for social media sharing in good lighting conditions, but expect struggles in low light. The inclusion of a 2MP macro camera on either device is largely a marketing gimmick, offering minimal practical benefit.

Performance

The Realme C51s’s Unisoc Tiger T612 is the clear winner here. Built on a 12nm process, it features a more modern CPU architecture with 2x 1.8 GHz Cortex-A75 cores and 6x 1.8 GHz Cortex-A55 cores, compared to the Nokia C12 Plus’s Unisoc SC9863A1 with 4x 1.6 GHz Cortex-A55 and 4x 1.2 GHz Cortex-A55 cores. This translates to significantly faster app loading times and smoother multitasking on the Realme. The A75 cores provide a substantial boost in single-core performance, crucial for responsive UI interactions. While both likely have limited RAM options, the chipset difference will be the dominant factor.

Battery Life

The Realme C51s shines in the battery and charging department. While the battery capacity isn’t specified, the inclusion of 33W wired charging, capable of reaching 50% charge in just 28 minutes, is a game-changer. The Nokia C12 Plus lacks fast charging, relying on standard 5W charging, meaning a full charge will take several hours. This difference in charging speed significantly impacts usability, especially for users who need to quickly top up their phone throughout the day.

Buying Guide

Buy the Nokia C12 Plus if you prioritize a streamlined, near-stock Android experience and absolute simplicity. It’s ideal for first-time smartphone users or those who prefer minimal bloatware. Buy the Realme C51s if you value performance for social media, light gaming, and multitasking, and if quick charging is a must-have feature. It’s better suited for users who actively use their phones throughout the day.
