Huawei children's watch 4x parameters

1. Truly waterproof: The industry’s true 5ATM, 50-meter waterproof machine adopts 5ATM waterproof components, and the buttons are waterproof and sealed; the speaker drains water with one button (15s), and the audio can be quickly restored after swimming; passed Huawei’s rigorous Waterproof test, the industry's first 50-meter waterproof children's watch supports swimming mode (duration, calories, etc.)*, making swimming more fun. It supports underwater buttons to take photos and videos, and the experience is unique. *50-meter waterproof: meets ISO22810:2010 standard 5ATM protection level Requirements, waterproof up to 50 meters, can be used for water activities in shallow waters such as swimming pools or beach swimming. Not suitable for diving, diving, hot showers, hot springs, saunas, other wading or deep water activities under high-speed water. After use in sea water, it is recommended to rinse with clean water and dry. When children swim or go into the sea, please pay attention to safety and be accompanied by someone who is familiar with the water. The time should not be too long. For product waterproofing precautions, please refer to the official website. *The swimming function does not support data viewing on the iOS version of the Smart Care APP, and can only be viewed on the watch. The current algorithm only supports calorie calculation for breaststroke, and other swimming styles will be supported by subsequent OTA upgrades. 2. Front and rear dual cameras: high-definition video calls, large wide angle and large aperture for fun photos. Front: 5 million pixels, 85° wide angle, F2.2 large aperture. Rear camera: 8 million pixels, 84° wide angle, F2.0 super large aperture AF auto. Dual-camera video calls before and after zooming, and free switching of screens. Huawei's full-scenario smooth call without opening the Smart Care APP. Huawei mobile phones, tablets, and smart screens can directly make audio and video calls to children's watches through smooth calls. Voice photography: Let children experience the fun of photography. Intelligent object recognition: The rear camera aims at an object and automatically and intelligently recognizes various common objects in three seconds. The associated knowledge points are automatically played to explore the world. Fun photography* (OTA support): Front camera support Dynamic stickers make taking photos more interesting. Slow-motion camera: 120fps slow-motion camera, experience the excitement of "slow". 3. Dual-frequency positioning: the same positioning chip of Huawei's flagship machine, dual-frequency positioning, five-mode satellite, 11-fold AI positioning, positioning More accurate dual-frequency positioning: (GPSL1/L5, GALILEOE1/E5a, QZSSL1/L5), stronger anti-interference performance, reducing the impact of high-rise buildings, thunderstorms and other factors, and improving positioning signal strength, stability, and accuracy. Five-mode constellation: GPS+Beidou+GLONASS+GALILEO+QZSS five-mode, and the above five-mode concurrent positioning; the industry’s maximum 144 acquisition channels, 117 tracking channels, and more than 11 satellite search and tracking satellites. Repositioning: In addition to five-mode satellite positioning ; There are also WLAN positioning, base station positioning, indoor positioning; A-GPS, accelerometer-assisted positioning, and SOS camera-assisted positioning. AI positioning: Huawei's NLP positioning algorithm, multi-source map fusion positioning, intelligently obtains the optimal positioning effect. For commonly used locations, the more you use it, the more accurate it becomes.

All-weather footprint recording: high-frequency, more accurate, low-power footprint recording 4. Worry-free battery life: low-power dual-core architecture chip, 800mAh high-density battery, diversified intelligent power saving, magnetic fast charging, worry-free battery life 800mAh (typical value) high-density battery, Huawei's diversified smart watch power-saving technology, longer battery life. In typical scenarios, it can be used for 2-3 days. In super power-saving mode, it can be used for 5 days with magnetic fast charging, and it can be charged 50 times in 20 minutes. %*, fully charged in 90 minutes, more convenient charging 5. The most complete frequency bands: 4G full Netcom, 5 modes and 20 frequencies, the most complete frequency bands in the industry; independent low-noise amplifier, stronger signal, clearer and more stable calls 4G full Netcom, support 5-mode 20 frequency bands*, more frequency bands, more stable connections, stronger global roaming coverage. Supports China Mobile, China Unicom, and Telecom VoLTE networks*, making calls clearer. The industry's first independent radio frequency low-noise amplifier improves signal reception capabilities and improves poor signals. Communication capabilities in the environment 6. Rheinland certification: Germany Rheinland T_V wearable device safety certification Safety certification: Germany Rheinland T_V wearable device safety certification, including waterproofing, battery, material, reliability and network security, etc. Shenzhen Consumer Association quality 9 certification 7. Sports mode: Statistics on swimming, rope skipping, and medium- and high-intensity activities refer to the "National Physical Health Standards for Youth" to evaluate rope skipping performance. Six-axis sensors + self-developed rope skipping algorithms intelligently detect the number of rope skipping to assist in improving children's rope skipping performance. Automatic recognition of medium- and high-intensity activities , Duration record * Step counting ranking and likes * Medium and high-intensity activity detection: exercise duration record when running, skipping, and swimming reach a certain intensity; this function requires subsequent OTA upgrade support; data viewing in the iOS version of the Smart Care APP is not supported. Only supports viewing on the watch 8. 1GB+16GB: 1GBLPDDR4 memory, 16GB large storage, smoother operation 9. Supports NFC: access control card, bus card, card swiping is easier
