Build Quality and Design

The Xiaomi Redmi Turbo 4 boasts an elegant White Cloud color with a simple and refreshing look, free from exaggerated elements. The standout feature is the striking red slender waistline that adds a bold touch while visually dividing the back into two distinct areas. The left side has a pure matte white finish, while the right side showcases an intricate rectangular pattern created using photolithography. The back cover itself maintains a smooth and delicate texture thanks to its 2.5D AG frosted glass, offering an impressive feel in hand. This is a noticeable improvement over its predecessor, evident as soon as you hold the device. The camera module retains the turbo series signature design now enhanced with integrated metal material and two red accents that align with the red waistline for a cohesive look. An interesting addition is the hidden dual warm and cool light setup in the camera module. These lights activate subtly during notifications, charging, or while playing music but only when the phone is placed face down and the screen is off. The design remains sophisticated and functional, making it a pleasure to hold and use. The device's weight has increased, now measuring 205 grams, with the screen protector adding an extra 20 grams. While not as light and thin as before, this tradeoff aligns with the turbo series goal of offering a more comprehensive and balanced configuration at an affordable price. The Redmi Turbo 4 is still a compelling option for those prioritizing a feature-packed experience. Overall, the Xiaomi Redmi Turbo 4's build quality and design are impressive, making it a solid choice for anyone looking for a well-rounded device.

Battery Life

The battery life of the Xiaomi Redmi Turbo 4 is a significant improvement over its predecessor. With a massive 6550mAh GSR battery, this device delivers substantial gains in power efficiency and durability. In our testing, we found that the phone used only 8% battery during 1 hour of 1080p video playback, 10% during 1 hour of WeChat video calls, and 16% during 1 hour of playing Honor of Kings. These results highlight its impressive ability to conserve power even under demanding conditions. What sets this battery apart is its advanced technology - silicon carbon anode with up to 6% silicon content providing exceptional performance even in ultra-low temperatures as low as minus 18°C. We conducted a test where we placed the phone in a freezer and repeated video playback and WeChat video call tests under the same conditions, and remarkably, it delivered the same power consumption performance as in normal temperatures. The Redmi Turbo 4 also supports 90W fast charging powered by Xiaomi's Surge P2 chip, which charges the phone to 33% in just 10 minutes, 73% in 30 minutes, and fully charged to 100% in 47 minutes. The combination of excellent durability and rapid charging makes the Redmi Turbo 4 a benchmark-setter for battery performance. Overall, the Xiaomi Redmi Turbo 4's battery life is one of its standout features, making it an ideal choice for users who want a device that can keep up with their needs without needing to be recharged frequently.
