• At least 80% of the battery's capacity is retained after 1600 complete charge cycles, as determined by tests conducted by vivo laboratories. These tests simulate daily user habits (charging and discharging 1.36 a day) and indicate that 1600 cycles equal approximately 6 years of usage. The above data was provided by vivo's lab according to tests conducted in a simulated environment, with ambient and battery temperatures of 23°C±2°C for a full charge and discharge. Actual results may vary due to differences in test equipment, the test environment, as well as personal usage patterns and habits.
• This product was tested under controlled laboratory conditions. As a precision electronic device, the mobile phone still carries a risk of damage from drops, so please avoid dropping or impacting it. Any intentional or human-induced damage to the device is not covered by the warranty.
• Lab test results are not definitive indicators of real-world performance, which may vary depending on software version, test environment, and specific device configurations. 
• IP68 & IP69: This product has been tested under controlled laboratory conditions and is rated as IP68 and IP69 under IEC standard 60529-2013. IP68 water resistance test conditions: Submerged in static clean water up to 1.5 meters deep for up to 30 minutes, with a temperature difference of less than 5°C between the water and the device. IP69 water resistance test conditions: (1) Rotation speed: (5±1) rpm. (2) Nozzle angles: 0°, 30°, 60°, and 90°. (3) Flow rate: (15±1) L/min. (4) Water temperature: (80±5)°C. (5) Test time: 30s/position. (6) The phone is placed in a vertical position with the USB port facing down. This product is not a professional waterproof phone. The resistance to splashes, water, and dust is not permanent and may decrease due to daily use. Do not immerse the phone in water during daily use or expose it to solutions such as seawater or other liquids such as beverages. Do not charge the phone when it is wet; instead, clean and dry it immediately. Damage due to liquid ingress is not covered by warranty. IP69+ indicates that the device meets both IP68 and IP69 water-resistance standards and has passed three consecutive IP69 tests on the same unit at the same angle. This model is not a professional waterproof device. It is resistant to splashes, water, and dust under normal use. Actual performance may vary.

• The pixel value may vary under different camera modes, and is subject to actual usage.
• Please follow the official guidelines when using this feature. Do not immerse the phone in non-fresh water during use. Please shoot underwater at a maximum depth of 1.5 meters and use it for no more than 30 minutes at a time. After using the phone underwater and removing it from the water, tap and hold the corresponding button on the screen to exit the Underwater Mode and allow the water to drain. Then place the phone in a dry, well-ventilated area to dry. Avoid charging or connecting external devices to the USB port until it is completely dry. Do not use high-temperature heating methods such as a hair dryer to dry the phone, which may damage the phone. Please note that due to differences in temperature and humidity, condensation and fogging may occur in the lens when the phone is immersed in water, which can be resolved by placing the phone in a constant temperature, low humidity environment for approximately 20 minutes. Damage caused by liquid ingress due to use of this feature without following official water resistance test conditions is not covered by warranty. Due to regulatory restrictions, Underwater Photography is not recommended for promotion in certain regions, including Europe, Brazil, Latin America, and Türkiye.
