Xiaomi MI 11i

The Xiaomi Mi 11i, also known as the Mi 11X Pro in India, is a premium smartphone that offers a great balance of features and price. While it cuts back on some features compared to its flagship sibling, the Mi 11, it still manages to impress with its sleek design, impressive display, and top-tier performance. The phone's design is quite similar to other recent Xiaomi phones, featuring a glossy back and a two-step camera bump. However, the frame is made of plastic instead of metal, which may be a letdown for some users. The Mi 11i also boasts an IP53-rated splash-proof rating, which is a nice touch. The display is a standout feature, with a flat 6.67-inch Super AMOLED panel offering great color accuracy and HDR10+ support. While it's not as sharp as the Mi 11's QHD display, it still provides excellent visuals. The phone also features a fast 120Hz refresh rate, which makes for smooth scrolling and gaming. Under the hood, the Mi 11i packs a powerful Snapdragon 888 chipset, which delivers top-notch performance and benchmark results. However, there is some thermal throttling during heavy use, but it's still one of the most powerful smartphones available at this price point. Camera-wise, the Mi 11i has a capable camera setup with a 108MP primary sensor, an 8MP ultra-wide lens, and a 5MP macro camera. While not perfect, it delivers great photos with good detail, natural colors, and excellent contrast. Nighttime shooting is also decent, but there's room for improvement. Overall, the Xiaomi Mi 11i is a solid choice for those looking for a premium smartphone without breaking the bank. However, considering its price, you may be able to find an actual flagship from a higher tier that offers more features and better performance.
