Y400

1. This product has been tested under controlled laboratory conditions and is rated as IP68 and IP69 under IEC standard 60529-2013. IP69 water resistance test conditions: A rotation speed of (5±1) rpm, nozzle angles of 0°, 30°, 60°, and 90°, a flow rate of (15±1) L/min, a water temperature of (80±5)°C, a test time of 30s/position, and the phone placed in a vertical position with the USB port facing up. IP68 water resistance test conditions: Submerged in water up to 2 meters for up to 30 minutes, with a temperature difference between the water and the device of less than 5°C. The resistance to splashes, water, and dust is not permanent and may be reduced due to daily use. Do not charge the phone when it is wet; instead, clean and dry it immediately. Damage caused by liquid ingress is not covered by warranty.

2. Actual available RAM/ROM is less due to the storage of the operating system and pre-installed apps.

3. Extended RAM is realized by software.

4. The typical battery capacity is 6000 mAh, and the rated battery capacity is 5860 mAh.

5. Y400 is equipped with a vivo standard charger and supports up to 90W of charging. Actual charging power is dynamically adjusted as the scene changes and subject to actual usage.

6. Actual dimensions and weight may vary due to processes variations, measurement methods, material supplies, and production batches.

7. Measured diagonally, the screen size is 16.94 cm (6.67 inches) in the full rectangle. Actual display area is slightly smaller.

8. The 120 Hz is not applicable to all scenarios.

9. Actual network functionality is subject to carrier network availability, applicable law and regulation, infrastructure support, and software version of the mobile phone.

10. Pixel value may vary in different camera modes and is subject to actual usage.

11. 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 2 meters and use it for no more than 30 minutes at a time. After using the phone underwater and removing it from the water, press 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. Please note that using high-temperature heating methods, such as hair dryers, during the drying process may damage the phone. Also 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 under warranty.

12. All data is based on our technical design parameters, laboratory test results, and supplier test data. Actual performance may vary depending on software version, specific test environment, and phone model.

13. Some specifications, parameters, or product parts may vary due to supplier changes or different production batches. Please take actual products as standard.
