Pros and Cons

Xiaomi Mix 4

Strengths

Impressive Under Display Camera: The Xiaomi Mix 4 boasts the best under-display camera (UDC) technology currently available, surpassing even the Axon 30 Fold 3 and the first-generation Axon 20.
Fast Charging: The phone supports incredibly fast charging at 120 watts, taking around 22-25 minutes to fully charge the battery.
Great Ceramic Build: The Mix 4 has a fantastic ceramic build, with a solid construction that feels premium in hand. It's just a bit on the heavier side, weighing over 220 grams.
Fast Wireless Charging: Despite not having the wireless charger on hand, the phone's wireless charging speed is around 30 minutes.

Weaknesses

Outdated Camera Sensor: The Mix 4's camera choice of a 108-megapixel HMX sensor from Samsung feels like a missed opportunity, especially considering it's slightly dated for late 2021. A GN2 camera would have been a more desirable upgrade.
Thermal Issues with Snapdragon 8+ Plus: Unfortunately, the phone's performance is hampered by thermal issues associated with the Snapdragon 8+ Plus chipset. This can lead to overheating and even booting out of demanding games or apps.

Xiaomi Mix 4

The Xiaomi Mi 11 is a phone that has left me with mixed feelings. On the one hand, it boasts some impressive specs, including a 108MP Samsung HMX sensor and a Qualcomm Snapdragon 8+ Plus chip. The phone's ceramic build and fast charging capabilities (120W) are also notable features. However, my experience with the camera was underwhelming. While the 108MP sensor is capable of producing high-quality images, it feels like an outdated choice in today's market. I would have preferred a GN2 sensor, which is used in the Mi 11 Ultra. The camera's performance is further compromised by its tendency to switch between digital and optical zoom modes. The Snapdragon 8+ Plus chip is another area of concern. While it delivers excellent performance, it also suffers from overheating issues when subjected to demanding tasks like gaming or benchmarking. This was evident in my experience with the Antutu benchmark test, which crashed due to excessive heat. Despite these drawbacks, the Mi 11 still has some redeeming qualities. The phone's ceramic build is solid and premium-feeling, and the fast charging capabilities are a welcome feature. However, the camera and thermal issues make it difficult for me to wholeheartedly recommend this phone. Overall, the Xiaomi Mi 11 is a phone with potential that falls short due to its mixed performance. While it may appeal to those seeking a fast-charging experience, I would caution gamers and photographers to look elsewhere.

The Vivo iQOO Z5 is an intriguing device that packs a punch in its price segment. With a sleek design and impressive specs, this smartphone promises to deliver on both performance and features. The device boasts a large battery life, making it perfect for heavy users, and the camera setup seems to be a strong point, offering a 64MP primary sensor and a capable selfie snapper. I put this phone through its paces, and my initial impression is that it's a formidable contender in the budget flagship space.
