The data is from our in-house lab tests and applies only to single-app use and standby conditions. Test environment: ambient temperature of 25°C±1°C. Test conditions: Device fully charged, screen brightness set to 150 nits, volume at 63 dB. Actual battery life may vary depending on usage habits, environment, and other factors.
• Data is obtained from vivo laboratory under single-app usage or standby conditions. Test environment: ambient temperature of 25°C±1°C. Test conditions: device fully charged, screen off, volume at 63 dB, and Wi-Fi connected. Actual battery life may vary with usage habits and environment. Headphone playback time of 80 hours is based on laboratory testing under single-app usage or standby conditions. Test environment: ambient temperature of 25°C±1°C. Test conditions: device fully charged, Bluetooth earphones connected, screen off, volume at level 7, and Wi-Fi connected. Actual results may vary.
• Data is obtained from vivo laboratory under single-app usage or standby conditions. Test environment: ambient temperature of 25°C±1°C. Test conditions: device fully charged, screen brightness of 150 nits, maximum volume, and 4G network. Actual battery life may vary with usage habits and environment.
• The data shown is from results of laboratory tests and refers to stand-by condition only. Test environment: ambient temperature of 25°C±1°C. Test conditions: device fully charged, screen brightness of 150 nits, and volume at 63 dB. Actual battery duration is subject to actual usage and may vary depending on environmental and other factors.
• Data is sourced from vivo laboratory tests. Reverse charging output power is 6W (5V/1.2A). Due to compatibility differences, some devices may experience lower charging power or may not be charged properly. Actual performance may vary.
• Based on tests conducted by vivo laboratories, the battery retains at least 80% of its capacity after 1600 full charge cycles. These tests simulate typical daily usage habits (one full charge–discharge cycle every 1.23 days), indicating that 1600 cycles are equivalent to approximately 5 years of use. All data is provided by vivo laboratories under simulated conditions, with ambient and battery temperatures maintained at 23°C±2°C, completing full charge and discharge cycles. Actual results may vary depending on test equipment, test environments, and individual usage patterns and habits.
• Y21 5G is equipped with a vivo standard charger and 44W FlashCharge of charging. Actual charging power is dynamically adjusted and is based on electricity output, external factors and subject to actual usage.
• Charging data is derived from vivo laboratory tests. Test environment: ambient temperature 25°C±1°C. Test condition: Charged by using the vivo official standard charger, in the off-screen state, with 1% of battery capacity. Actual charging speed is subject to actual usage and may vary depending on environment and other factors.
• This product has been tested under controlled laboratory conditions. Since the phone contains precision components, please make sure not to bump or drop the phone during use. Any artificially caused damage to the device is not covered by warranty. 
• Lab test results are not definitive indicators of real-world performance. Actual results may vary depending on software version, test environment, and specific phone variant. 
• This product has been tested under controlled laboratory conditions and is rated as IP65 under IEC standard 60529-2013. IP65 water resistance test conditions: A water flow rate of (12.5±0.625) L/min for 3 minutes of continuous spraying at a nozzle distance of 2.5 to 3 meters from the test phone. This product is not a professional waterproof phone. The resistance to splashes, water, and dust is not permanent and may be reduced 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 caused by liquid ingress is not covered by the warranty.
• Data is obtained from vivo laboratory, in which a new phone is tested for 8 consecutive hours in a simulated rain environment. Do not charge the phone when it's wet. As real life scenarios may differ from the experimental environment, the actual experience shall prevail. If the phone is exposed to raindrops or splashes, the liquid may block the audio/reception pipes of the microphone, receiver, and speaker, resulting in abnormal audio/reception during calls and playback. The function can be restored by shaking the liquid off and leaving it to dry. The resistance to water and dust may be reduced due to daily wear and tear. Damage due to liquid ingress is not covered by the warranty.
• This phone is not a professional waterproof mobile phone. No functional problems occurred during testing in vivo lab environments under the condition that the phone was rinsed for 120 seconds with water at a flow rate of 6 liters per minute and then was left unused for 24 hours. The resistance to water is not permanent and may be reduced due to daily wear and tear. If the phone is exposed to the rain or water splashes, the audio/reception pipes of the microphone, receiver, and speaker may be blocked, resulting in abnormal audio/reception during calls and playback. To restore the function, please keep the phone unused and leave it to dry. Do not charge the phone when it is wet. Damage due to liquid ingress is not covered by the warranty.
