Haylou RS4 Plus Design & Build


The Haylou RS4 Plus boasts a design that takes a departure from its predecessor, the RS3, with notable improvements that enhance its aesthetics and functionality. The square-shaped watch replaces the rounded dial, resembling the sleek elegance of Apple Watches. The transformation from two buttons to a single crown for the power function adds to its minimalist appeal.

Sporting a glossy metal frame and a matte-finished plastic back, the build quality strikes a balance between premium and practical. The 2D curved design of the curved glass enhances the overall seamless appearance, while the lone power button on the right side simplifies the watch’s interface.


For build quality, you get a glossy metal build for the frame, but a plastic back, which doesn’t look that cheap because of the matte finish. Measuring 45mm in dial size and only 10.4mm in thickness, the RS4 Plus feels slim and comfortable on the wrist, catering to most hand sizes. Weighing just 57.6 grams with the strap, it ensures lightweight and enjoyable wear throughout the day.

Haylou RS4 PlusBattery Life

The Haylou RS4 Plus comes equipped with a 230mAh battery, which is decent considering its AMOLED panel and advanced health and sports activity sensors. However, it struggles a bit to keep up with the power demands of all its features when used extensively, mimicking a smartwatch.

The company promises a minimum of 10 days of battery life, but real-world usage reveals it to be closer to 7 to 10 days, depending on usage patterns. If you fully utilize its smartwatch capabilities and all its features regularly, the battery life will inevitably be shorter.


Charging the Haylou RS4 Plus is hassle-free with the included USB-A to magnetic charging pin connector. The magnetic connection securely attaches to the back of the watch, making charging efficient and convenient.
