Waterproof Level
5 ATM water-resistant 
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).
The product 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) Free dives, scuba dives, and any other diving activities. (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.
Water resistance is not permanent, and performance may deteriorate with daily wear and tear. It is recommended that you regularly take your device to an authorised Huawei service center for inspection and maintenance.

Battery Life
The battery can last for up to 10 days with light usage, up to 7 days with typical usage, or up to 4 days with AOD enabled.
The battery life with light usage is tested under the following conditions: default settings, 30 minutes of Bluetooth calling per week, 30 minutes of music playback per week, heart rate monitoring always on, HUAWEI TruSleep™ enabled at night, 90 minutes of exercise on average per week, message notifications enabled (50 messages, 6 calls, and 3 alarms per day), and the device screen turned on 200 times per day.
The battery life with typical usage is tested under the following conditions: default settings, 30 minutes of Bluetooth calling per week, 30 minutes of music playback per week, heart rate monitoring always on, HUAWEI TruSleep™ enabled at night, stress monitoring enabled, pulse wave arrhythmia analysis and sleep breathing awareness features enabled, 180 minutes of exercise on average per week, message notifications enabled (50 messages, 6 calls, and 3 alarms per day), and the device screen turned on for a total of 30 minutes per day.
The battery life with AOD enabled is tested under the following conditions: default settings, AOD enabled, 30 minutes of Bluetooth calling per week, 30 minutes of music playback per week, heart rate monitoring always on, HUAWEI TruSleep™ enabled at night, automatic stress monitoring enabled, pulse wave arrhythmia analysis and sleep breathing awareness features enabled, 180 minutes of exercise on average per week, message notifications enabled (50 messages, 6 calls, and 3 alarms per day), and the device screen turned on for a total of 30 minutes per day.
