Waterproof Level
5 ATM
Complies with 5 ATM-rated water resistance under the ISO 22810:2010 standard, which indicates that the device can withstand up to 50 metres of static water pressure for 10 minutes, but does not mean that the product is water-resistant in water that is 50-metre deep.
IP6X
Complies with the IEC 60529:2013 standard (level 6).
Dive (Depth up to 40 metres)
Complies with the EN13319 standard for diving accessories, and supports free dives at depths of up to 40 metres. It can be worn during shallow water activities such as swimming in a pool or along the coast. After wearing the device in water activities, clean and dry it promptly, remove the water stains from the product surfaces and all holes, and use the device's drainage feature to avoid negative impact on device performance.
The product should not be worn in the following scenarios: (Damage to the device caused by immersion in liquid is not covered by the warranty if the device is worn in an inappropriate scenario.) (1) Hot showers, hot springs, saunas (steam rooms), and other activities in high-temperature and/or high-humidity environments. (2) Activities that could expose the device to shower gel, shampoo, soapy water, and any other laundry or cleaning products. If the device does come into contact with any such product, rinse and soak the device in fresh water for 30 minutes. (3) Scuba dives, technical dives, and diving activities at depths greater than 40 metres. (4) Nylon straps are not designed for water activities (such as swimming) or to withstand sweat, and therefore it is recommended that other straps be used in such scenarios.

Battery Life
The 10-day maximum battery life is tested under the following conditions:
factory default settings, Bluetooth call 30 minutes/week, music playback 30 minutes/week, heart rate always on, science sleep at night, average weekly exercise 90 minutes, and message notification enabled (50 messages, 6 calls, 3 alarms per day) 2. Turn on the screen 200 times a day.
The 7-day typical battery life is tested under the following conditions:
factory default settings, Bluetooth call 30 minutes/week, music playback 30 minutes/week, heart rate always on, scientific sleep at night, pressure detection, pulse wave arrhythmia analysis and sleep breathing awareness detection, 180 minutes of average weekly exercise, and message notification (50 messages, 6 calls, 3 alarms per day) 2. Turn on the screen for 30 minutes every day.
The 4-day battery life with AOD enabled is tested under the following conditions:
factory default settings, screen off, Bluetooth call 30 minutes/week, music playback 30 minutes/week, heart rate normally on, science sleep at night, pressure automatic detection, pulse wave arrhythmia analysis, and sleep breathing awareness detection features, 180 minutes of average weekly workout, and enable message notification (50 messages, 6 calls, and 3 alarms per day) 2. Turn on the screen for 30 minutes every day.
