Display Comparison
The provided data lacks detailed display specifications for the vivo Y55s. However, given its market positioning, it likely features a standard 60Hz LCD panel. The Realme 9 Pro+, while lacking specifics like peak brightness, benefits from a contrast ratio described as 'Infinite' – suggesting a VA panel offering deeper blacks than a typical IPS LCD. This difference in panel technology, combined with the potential for higher brightness on the Realme, will result in a more vibrant and immersive viewing experience. The absence of refresh rate data for the Y55s further highlights the Pro+'s potential advantage, assuming it offers a smoother experience.
Camera Comparison
Without detailed camera specs beyond the mention of 'Photo/Video', a direct comparison is limited. However, the Realme 9 Pro+ likely benefits from a more advanced image signal processor (ISP) integrated within the Dimensity 920, enabling better noise reduction and dynamic range. The Y55s’ ISP, tied to the Dimensity 700, will be less capable. While both phones may feature similar megapixel counts, the Realme’s superior processing power will likely result in better image quality, particularly in low-light conditions. The absence of information regarding OIS or sensor size makes a definitive statement impossible, but the chipset advantage leans heavily towards the Realme.
Performance
The core difference lies in the chipsets. The Realme 9 Pro+’s Mediatek Dimensity 920 (6nm) is a substantial upgrade over the vivo Y55s’ Dimensity 700 (7nm). The 920 utilizes Cortex-A78 cores clocked at 2.5 GHz, compared to the Y55s’ Cortex-A76 cores at 2.2 GHz. This architectural shift, coupled with the smaller 6nm process node, translates to significantly improved CPU and GPU performance. The Dimensity 920 will handle demanding games and multitasking with greater ease, while the Dimensity 700 may struggle with sustained loads. Both phones share 6x2.0 GHz Cortex-A55 efficiency cores, but the 920’s overall processing power is considerably higher.
Battery Life
The Realme 9 Pro+’s 60W wired charging is a game-changer. Advertised to reach 100% in just 44 minutes, it drastically reduces charging times compared to the vivo Y55s’ 18W charging. While the Y55s’ battery capacity isn’t specified, the Realme 9 Pro+ boasts an endurance rating of 117 hours, suggesting a well-optimized battery life. The faster charging speed of the Realme mitigates any potential disadvantage in battery capacity, making it the more convenient option for users who frequently need to top up their phones.
Buying Guide
Buy the vivo Y55s (2021) if you need a functional, reliable smartphone for basic tasks like calling, texting, and light social media use, and your budget is extremely limited. Buy the Realme 9 Pro+ if you prioritize faster performance for gaming and demanding apps, value rapid charging, and are willing to spend a bit more for a more refined overall experience.
