vivo Y51 (2020, September)

  • Qualcomm Snapdragon 665 chipset offers good efficiency.
  • Potentially wider availability of Google Mobile Services.
  • Reliable brand reputation for software updates (regional variations apply).

  • Slower 18W charging.
  • Likely a less bright display compared to the Huawei.
  • Older chipset architecture compared to the Kirin 710A.

Huawei P smart 2021

  • Faster 22.5W fast charging (46% in 30 minutes).
  • Slightly brighter display (442 nits).
  • Proven 119-hour endurance rating.

  • Kirin 710A chipset may have limited software support.
  • Reliance on Huawei’s AppGallery ecosystem.
  • 14nm process is less efficient than the Snapdragon's 11nm.

Display Comparison

The Huawei P smart 2021 boasts a measured peak brightness of 442 nits, a noticeable advantage over what’s likely a standard IPS panel on the vivo Y51. Both displays share a 1252:1 contrast ratio, suggesting similar black levels. While neither phone will challenge flagship displays, the Huawei’s higher brightness improves outdoor visibility. The lack of refresh rate information for both suggests standard 60Hz panels, limiting smoothness compared to higher refresh rate alternatives.

Camera Comparison

Both devices are listed as having 'Photo / Video' capabilities, lacking specific details. Given the price point, expect modest camera performance. Sensor size and aperture are critical, but absent from the data. The vivo Y51’s camera system is likely optimized for social media sharing, while Huawei’s image processing typically emphasizes vibrant colors. Without detailed specifications, it’s difficult to declare a clear winner; however, Huawei’s history suggests a more refined camera experience, even with similar hardware.

Performance

The core difference lies in the chipsets. The Qualcomm Snapdragon 665 (11nm) in the vivo Y51 utilizes Kryo 260 cores, offering a balance of performance and efficiency. However, the Huawei P smart 2021’s Kirin 710A (14nm) employs Cortex-A73 cores, which, despite the larger manufacturing process, can deliver comparable, and in some cases, superior performance in multi-threaded tasks. The Kirin 710A’s architecture is older, but its core design is more powerful. Real-world performance will likely be similar for everyday tasks, but the Kirin 710A might show a slight edge in demanding applications. Both phones likely feature similar RAM configurations, further minimizing the performance gap.

Battery Life

Both phones achieve an impressive endurance rating of 119 hours, indicating similar battery life under typical usage. However, the Huawei P smart 2021’s 22.5W fast charging significantly outperforms the vivo Y51’s 18W charging. The Huawei can reach 46% charge in just 30 minutes, a substantial convenience advantage. While both offer all-day battery life, the Huawei’s faster charging mitigates range anxiety and allows for quicker top-ups.

Buying Guide

Buy the vivo Y51 (2020, September) if you prioritize a Qualcomm chipset and a potentially wider availability of Google Mobile Services (depending on region). Buy the Huawei P smart 2021 if you value faster charging speeds, a slightly brighter display, and a proven endurance rating, even if it means relying on Huawei’s AppGallery ecosystem.

Frequently Asked Questions

❓ Does the Huawei P smart 2021’s Kirin 710A chipset suffer from significant thermal throttling during prolonged gaming sessions?
While the Kirin 710A isn’t a gaming powerhouse, its thermal performance is generally adequate for casual gaming. The 14nm process isn’t as efficient as the Snapdragon 665’s 11nm, but Huawei’s software optimizations likely mitigate throttling to a reasonable extent. Expect playable frame rates in less demanding titles, but demanding games may require reduced graphics settings.
❓ How does the lack of Google Mobile Services (GMS) on the Huawei P smart 2021 impact the user experience?
The Huawei P smart 2021 relies on Huawei’s AppGallery and HMS (Huawei Mobile Services) instead of GMS. While AppGallery is growing, it lacks the breadth of apps available on the Google Play Store. Users can sideload apps, but this requires technical knowledge and may pose security risks. Huawei is actively working to expand AppGallery, but GMS compatibility remains a significant consideration.
❓ Is the 18W charging on the vivo Y51 (2020) sufficient for typical daily use?
While 18W charging isn't slow, it's noticeably slower than the 22.5W charging on the Huawei P smart 2021. It will still charge the phone overnight, but users who frequently need quick top-ups will find the Huawei's charging speed more convenient. The vivo Y51's battery life is comparable, but the charging speed is a clear disadvantage.
