31g Feather-Light Body. Sometimes Less Is MoreThe Amazfit Bip S is designed to be more powerful than the previous generation, thanks to the revolutionary design of the watch materials and manufacturing process, while remaining ultra-lightweight. With only 31 grams with the watch band, the watch is very comfortable to wear while doing sport or sleeping.New Two-Tone Technology, Makes the Watch Stand Out Even MoreThe case is designed with seamless two-color technology to fuse two different shades of polycarbonate material, allowing different colors while ensuring hardness, lightness, and a highly expressive appearance.Cleaning Wristband Process, Soft, Dry, Dirt ResistantThe Amazfit Bip S uses the Cleaning wristband manufacturing process developed by Huami Technology. Molecular lattice technology ensures the entire wristband is soft, dry, and resistant to dirt, making it perfect for long-term wear.* The cleaning process is applied on the silicone straps only (white rock, red orange, warm pink), the carbon black strap is made of skin-friendly TPU which is already dry, so it does not require it.Excellence in DetailsThe Amazfit Bip S is built with excellence in mind down to the smallest details, even the buttons. The 316L stainless steel button is finely machined by high-precision CNC machine tools, sandblasted, and treated with a PVD vacuum coating process to make the surface of the button colorful and wear resistant. In the middle of the button, the watch's color scheme is matched through a tone drip process, which enhances the overall fullness and design details of the watch and adds a finishing touch. 4 Color Options Are AvailableThe Amazfit Bip S has a color-changing watch body with shades including carbon black, white rock, red orange and warm pink to satisfy your desire for color and expression.40-Day Battery Life. Charge Once, Use for One MonthThe Amazfit Bip S has outstanding battery life thanks to th electronic components selection and power optimization technology.* Test conditions for 40-day battery life: factory default dial, running once a week for half an hour, 100 notifications per day, default brightness 10%. In actual use, battery life is related to various factors such as settings, operations, and operating conditions, and therefore may differ from laboratory data. Transflective Color Display Does More with LessThe ingenious transflective color display allows you to clearly see the screen while taking advantage of low power consumption and eye protection even if the power-intensive backlight is not turned on. It performs even better in outdoor environments, since the brighter the sunlight is, the clearer the display looks, making it ideal for outdoor sports. When the ambient light is low, you can turn on the watch backlight to fully illuminate the screen.High-precision Sony 28nm low power GPS, 22 hours of continuous workThe built-in Sony 28nm GPS chip, through several product updates and iterations, as well as continuous optimization and adjustment, performs even better in satellite search speed, positioning accuracy, and power consumption. The GPS can operate continuously for 22 hours.* Test conditions for 22 hours GPS continuous working time: GPS continuously on, heart rate always on. In actual use, battery life is related to various factors such as settings, operations, and operating conditions, and may differ from laboratory data.Lightweight Body, High-Capacity Battery, Higher-Conversion Power ChipInside the slim body of the Amazfit Bip S, the built-in battery has a capacity of 200mAh. The use of a high-performance switching regulator power chip (low-current high-efficiency DCDC) and optimized Bluetooth reduces power consumption, improves device efficiency, and provides sufficient power for a long battery life.Huami's Self-Developed Biotracker™ PPG Bio-Tracking Optical Sensor, Improves Accuracy and Reduces Power Consumption by 80%The Amazfit Bip S uses the BioTracker™ PPG Bio-Tracking Optical Sensor independently developed by Huami Technology. The effective high-precision sensing area is 3 times that of the previous generation, the LED luminous intensity is 7 times that of the previous generation, and the heart rate monitoring accuracy is improved to 98%, all while using only one-fifth the power of the previous generation of products, making this a significant advance for watches with full-day heart rate monitoring. Functional and Practical Features, Right at Your WristAmazfit Bip S is small, but it contains a lot of potential. Water Resistant to 5 ATM, it supports 10 sports modes including swim tracking, the continuous heart rate monitoring and PAI Health assessment system provide useful tools to improve your health and workout efficiency.
