Display Comparison
Neither device boasts a standout display. While specific display specs (resolution, panel type) are missing for the Y400, both phones likely utilize IPS LCD panels common in this price bracket. The key difference lies in the processing power driving the display; the Snapdragon 732G in the Redmi Note 12 Pro 4G has a more powerful ISP and GPU, potentially leading to slightly better image processing and smoother animations. Bezels are expected to be similar, and color accuracy will likely be adequate but not exceptional on both.
Camera Comparison
Without detailed camera specifications, a direct comparison is limited. However, the Snapdragon 732G’s superior ISP in the Redmi Note 12 Pro 4G offers an advantage in image processing. It can handle more complex algorithms for noise reduction, dynamic range, and detail enhancement. While both phones likely feature a multi-camera setup, the Redmi Note 12 Pro 4G’s image processing capabilities will likely result in more consistently pleasing photos, especially in challenging lighting conditions. We anticipate both phones will include a standard macro lens, which are generally of limited utility.
Performance
The core differentiator here is the chipset. The Xiaomi Redmi Note 12 Pro 4G’s Snapdragon 732G (8nm) represents a step up in performance compared to the vivo Y400 4G’s Snapdragon 685 (6nm). While the 6nm process of the 685 *should* offer better efficiency, the 732G’s Kryo 470 Gold cores, clocked at 2.2 GHz, provide a more substantial performance boost in CPU-intensive tasks. The 732G also features a more capable Adreno 618 GPU, translating to a better gaming experience. The Snapdragon 685’s Cortex-A73 cores at 2.8 GHz are respectable, but the 732G’s architecture is more refined for sustained performance. The Redmi Note 12 Pro 4G will handle multitasking and demanding apps with greater ease.
Battery Life
The Redmi Note 12 Pro 4G’s 67W wired charging is a significant advantage. This allows for a much faster 0-100% charge time compared to the vivo Y400 4G’s 44W charging. While battery capacity isn’t specified for either device, the faster charging speed of the Redmi Note 12 Pro 4G mitigates any potential disadvantage from a slightly smaller battery. Users who frequently find themselves needing to top up their phone quickly will greatly benefit from the Redmi’s charging capabilities.
Buying Guide
Buy the vivo Y400 4G if you prioritize a slightly newer chipset architecture and potentially longer software support from vivo, and your usage is primarily focused on basic tasks like calling, texting, and light social media. Buy the Xiaomi Redmi Note 12 Pro 4G if you value faster performance for gaming and multitasking, and the convenience of significantly quicker 67W charging, even if it means an older chipset.
Frequently Asked Questions
❓ Will the Snapdragon 685 in the vivo Y400 4G struggle with graphically demanding games like PUBG Mobile?
While the Snapdragon 685 can run PUBG Mobile, you'll likely need to lower the graphics settings to achieve a consistently smooth frame rate. The Snapdragon 732G in the Redmi Note 12 Pro 4G offers a more comfortable gaming experience with higher settings and more stable performance.
❓ How much faster is the 67W charging on the Redmi Note 12 Pro 4G compared to the 44W charging on the vivo Y400 4G?
The 67W charging on the Redmi Note 12 Pro 4G can typically charge a phone from 0-100% in around 45-60 minutes, while the 44W charging on the vivo Y400 4G will likely take closer to 75-90 minutes. This difference is significant for users who need a quick power boost.
❓ Does the Snapdragon 732G in the Redmi Note 12 Pro 4G get noticeably hot during extended gaming sessions?
The Snapdragon 732G is generally well-managed in terms of thermal performance. While it will get warm during prolonged gaming, it's unlikely to experience significant throttling due to its efficient 8nm process and Xiaomi's thermal management solutions. The vivo Y400 4G's 6nm process might run slightly cooler, but the 732G's overall performance advantage outweighs this minor difference.
