Display Comparison
Neither vivo nor Infinix provide detailed display specifications beyond resolution. However, given the price bracket, both likely utilize IPS LCD panels. The key differentiator lies within the processing power driving the display. A faster chipset, like the G70 in the Y21G, can contribute to smoother animations and faster response times, even on a similar panel. Bezels are expected to be substantial on both devices, reflecting their budget positioning. Color accuracy is unlikely to be a strong point on either model, and neither is expected to feature high refresh rate technology.
Camera Comparison
Detailed camera specifications are unavailable. However, given the market segment, both phones likely feature a primary camera paired with auxiliary sensors of limited utility. The image processing capabilities of the Helio G70 in the Y21G *may* offer slightly better noise reduction and dynamic range, but the quality will largely depend on the primary sensor used. Expect both phones to struggle in low-light conditions. Focusing on megapixel counts alone is misleading; sensor size and lens aperture are far more critical factors, and these are not provided.
Performance
The core difference between these two phones is the chipset. The vivo Y21G’s Mediatek Helio G70 utilizes a more sophisticated CPU architecture. Its octa-core configuration includes two Cortex-A75 cores clocked at 2.0 GHz, providing significantly higher single-core performance than the Infinix Smart 6 Plus’s Helio G25. The G25 relies on four Cortex-A53 cores at 2.0 GHz and another four at 1.5 GHz. The A75 cores in the G70 are demonstrably more efficient and powerful, resulting in faster app launch times and a more fluid multitasking experience. While both chipsets are 12nm, the architectural advantage of the G70 is substantial. The G70 also benefits from a more capable GPU, offering a better gaming experience, though neither phone is designed for high-end gaming.
Battery Life
Both devices likely feature similar battery capacities (around 5000mAh, based on market trends). The vivo Y21G’s 18W charging is a slight advantage over the likely 10W charging on the Infinix Smart 6 Plus, translating to faster top-up times. However, the more efficient Helio G70 chipset in the Y21G may also contribute to slightly better battery life during typical usage, as it requires less power to perform the same tasks. The difference in real-world usage will likely be marginal, but the faster charging is a tangible benefit for the Y21G.
Buying Guide
Buy the vivo Y21G if you prioritize smoother app switching, a more responsive user experience, and the ability to handle moderately demanding games. This phone is ideal for users who frequently use social media, browse the web with multiple tabs, or occasionally play mobile games. Buy the Infinix Smart 6 Plus (India) if your primary needs are basic communication – calls, texts, and light social media – and you are looking for the absolute lowest possible price point. It’s a suitable option for first-time smartphone users or those on a very tight budget.
Frequently Asked Questions
❓ Will the Infinix Smart 6 Plus handle popular games like PUBG Mobile or Call of Duty?
The Helio G25 in the Infinix Smart 6 Plus is not designed for demanding games. While you might be able to run PUBG Mobile at the lowest settings, expect significant frame rate drops and a generally poor gaming experience. The Helio G70 in the vivo Y21G will provide a noticeably better, though still limited, gaming experience.
❓ Is the difference in performance between the Helio G70 and G25 noticeable in everyday tasks like browsing and social media?
Yes, the difference is quite noticeable. The Helio G70’s Cortex-A75 cores provide a significant boost in single-core performance, resulting in faster app launch times, smoother scrolling, and a more responsive user interface. The Helio G25 will feel sluggish in comparison, especially when multitasking.
❓ Does the vivo Y21G support fast charging protocols beyond 18W?
While the vivo Y21G supports 18W wired charging, it's unlikely to support more advanced fast charging protocols like Quick Charge or Power Delivery. The included charger is likely a standard 18W adapter.
❓ How does the software experience differ between vivo and Infinix?
Both vivo and Infinix utilize customized Android skins. Vivo’s Funtouch OS is generally considered to be more polished and feature-rich, while Infinix’s XOS is often criticized for pre-installed bloatware. Software updates may also be more frequent and reliable on vivo devices.
