Product Overview
XL-B15 is an activity tracker designed for lightweight, breathable, all-day comfort. Its approximately 12 g body and woven nylon strap reduce the heat often associated with silicone straps in warm weather or heavy perspiration. The hook-and-loop closure is quick to put on and allows fine adjustment for different wrist sizes and for exercise, commuting, rest, and sleep.
The compact device uses a 0.96-inch 80 × 160 TFT color display with single-point touch control to show time, activity data, exercise status, and notifications. Raise-to-wake, brightness control, weather, alarm, timer, remote camera, incoming-call alerts, and app notifications provide common information without repeatedly checking the phone. Changeable watch faces add personalization to this entry-level fitness band.
XL-B15 records steps, distance, and calories and includes 16 sports modes for different training activities. Heart rate, blood oxygen, sleep, and stress features show long-term trends, while sedentary and hydration reminders support regular habits. The Runmefit app provides fuller history, activity routes, and watch-face content. This consumer wellness data is for everyday trend reference and cannot replace medical testing.
The 170 mAh battery provides about 5–7 days of normal use and up to 45 days of standby, with magnetic charging in approximately 2 hours. IP68 water resistance suits exercise sweat, handwashing, and rain. The device supports 19 interface languages, with customization available for case and strap colors, logos, packaging, multilingual manuals, startup screens, UI, exclusive watch faces, and software interfaces for e-commerce, retail, corporate purchasing, and gifting.
