Features and Build Quality of the Smart Sports Watch

This section details the specific components and construction that enable the RS4 Plus's performance, from its vivid screen to its durable, water-resistant design.

Vivid AMOLED Display and Interface

The centrepiece is a 1.78-inch AMOLED screen, which provides deep blacks and vibrant colours for excellent outdoor visibility. With a resolution of 368 by 448 pixels, text and watch faces appear sharp and legible. This display technology is more power-efficient than standard LCDs, contributing directly to the extended 10-day battery life, allowing you to keep the screen active for notifications and timekeeping without significant drain.

Battery Performance and Connectivity Specifications

Powering the device is a 230mAh lithium-ion battery. Under typical usage with 24-hour heart rate monitoring enabled, it delivers approximately 10 days of operation on a single charge, reducing charging interruptions. The watch maintains a stable connection to your smartphone via Bluetooth 5.1, which offers improved range and power efficiency over older versions for reliable data syncing to the Haylou Fun app on compatible Android and iOS devices.

Durable Construction and Water Resistance

Built to withstand an active lifestyle, the watch carries an IP68 ingress protection rating. This certification confirms protection against dust and allows immersion in water, making it suitable for swimming and use in the rain. The case measures 45.2mm by 37.2mm with a 10.4mm profile, housing the electronics securely. Paired with a 20mm wide strap, the total weight is kept to 57.6 grams for a comfortable, unobtrusive fit during all activities.

The motion sensor accurately captures movement patterns for each selected activity.

Everyday Use for Health and Convenience

In daily life, the watch offers a smooth, lightweight experience. The 57.6-gram weight and contoured 10.4mm profile mean it sits comfortably on the wrist for 24/7 wear, enabling seamless sleep stage monitoring.

The water and dust resistance extend the product's lifespan in varied environments, from humid gyms to rainy commutes. This durability, combined with the breadth of 105 activity trackers, means one device reliably replaces multiple specialised fitness gadgets.
