Product Overview
XL-B20 combines a slim body, full-touch interaction, and multi-scenario activity tracking. Its approximately 15 g body and 9.98 mm thickness reduce presence during long wear for commuting, training, sleep records, and travel. The quick-release silicone strap comes in several common colors for clothing, exercise scenarios, or brand identity.
The 1.47-inch 172 × 320 TFT color display uses full-touch control with a virtual side button for direct access to activity data, wellness trends, notifications, and common tools. Incoming-call and app notifications, event reminders, weather, alarm, timer, stopwatch, flashlight, Find My Phone, a watch-face library, and custom watch faces extend the band beyond activity tracking into everyday information and quick controls.
XL-B20 covers more than 100 sports modes and records steps, distance, calories, and recent activities for users with varied routines. A dual-color, three-channel PPG sensor tracks everyday heart-rate, blood-oxygen, stress, and sleep trends and supports breathing exercises, women's wellness, and reminders. Runmefit provides historical data, watch-face changes, and additional features. All wellness results are for everyday trend reference only.
Published specifications list a 245 mAh lithium-polymer battery with about 5–10 days of normal use, up to 45 days of standby, and magnetic charging in approximately 2 hours. IP68 water resistance handles common daily water exposure and exercise sweat. Retail, e-commerce, corporate-gift, and brand projects can evaluate strap materials and colors, body or buckle logos, exclusive watch faces, startup screens, UI, packaging, multilingual manuals, and SDK/API interfaces.
