Redmi Watch 4 Review: Affordable Elegance with Top-notch Features

In the wake of Xiaomi’s 10th-anniversary celebration, which saw the release of the highly anticipated K70 series, the Redmi Watch 4 emerged as a standout among the supporting accessories. This budget-friendly smartwatch marked a significant departure for the series, donning a metal armor for the first time.

Eager to explore the potential of this new entrant, I wasted no time in acquiring one for myself. As I delved into the Redmi Watch 4’s features, design, and performance, it became clear that Xiaomi had crafted a compelling contender in the affordable smartwatch arena.

Design and Build Quality

Upon unboxing, the Redmi Watch 4 immediately exudes a premium feel, thanks to its metal shield design. The aluminum frame brings a refreshing change, a stark contrast to its predecessor, the Redmi Watch 3, which struggled to convincingly imitate a metallic appearance with its plastic frame. The watch 4 is noticeably lightweight, with the metal build adding just 10 grams compared to its predecessor, bringing the total weight (excluding straps) to a manageable 32 grams.

The matte finish on the metal surface not only enhances the premium look but also keeps fingerprints at bay. An interesting detail is the stainless steel Crown with a subtle texture, contributing to an overall polished appearance. However, the sharp edges on the front face raise some concerns about potential scratches and scuffs, especially for those who lead an active lifestyle.

One peculiar issue arises for users, like myself, who wear the watch on their left wrist. Tying it too tightly might lead to accidental touches of the protruding crown. While this could be a minor inconvenience, it’s worth noting for those who prioritize wrist comfort.

The Redmi Watch 4 also brings good news for those who enjoy customization. It supports Xiaomi’s quick-release straps, making it easy to swap them out for different styles. This compatibility with other Xiaomi wearables’ straps expands the options for personalization.


Display Quality and Features

The front side of the Redmi Watch 4 maintains the square dial design characteristic of Apple’s watches. With a 1.97-inch AMOLED display and a commendable 74.8% screen-to-body ratio, the watch provides a more immersive information display compared to its predecessor. The display quality is impressive, offering vivid colors and decent resolution.

Outdoor usability is enhanced by the auto-adjustable brightness, reaching up to 600 nits in bright daylight. One notable feature is the variable refresh rate, allowing the display to run at 60Hz for a smooth experience and dropping to 5Hz in Always-On Display (AOD) mode for improved power efficiency.

The Redmi Watch 4 runs on the latest Xiaomi Hyper OS, making it the second Xiaomi wearable to feature this operating system. The software offers a wide selection of personalized displays, catering to diverse user preferences. Navigating the user interface is straightforward, with swipes in different directions on the dial page to access notifications and widgets. However, the absence of a dedicated shortcut button for actions like starting sports might be a drawback for some users.

Health and Fitness Tracking

The Redmi Watch 4 excels in health and fitness tracking, incorporating an upgraded heart rate monitoring sensor for more accurate readings. It supports 24/7 auto-tracking of blood oxygen levels, adding a valuable health metric to the mix. Other features include sleep tracking, stress tracking, female cycle reminders, and breathing training.

For sports enthusiasts, the watch supports an extensive list of over 150 sports modes, covering a wide range of activities. From water sports and outdoor pursuits to ball sports and more, the Redmi Watch 4 is a versatile companion for various physical activities. The built-in independent GNSS chip allows for outdoor running tracking without the need for a connected phone. With a 5 ATM water resistance rating, it’s also suitable for swimming.

However, caution is advised for certain sports with sharp movements, such as basketball and football, as the watch’s sharp edges could pose a risk of injury to others.

Connectivity and Battery Life

The Redmi Watch 4 introduces several improvements in connectivity, featuring NFC for convenient offline mobile payments and a full transportation card simulation, particularly useful for users in China.

Despite these enhancements, the watch falls short of fully leveraging Xiaomi’s Multi-Device connectivity, offering only a switch for smartphones in various scenarios. Additionally, the voice assistant functionality is currently limited to Chinese, potentially excluding a broader international audience.

One of the most promising aspects of the Redmi Watch 4 is its impressive battery life. Xiaomi claims a 50% to 80% improvement, with the watch capable of lasting up to 10 days in typical AOD mode and an impressive 20 days in typical mode with default factory settings.
