• Unless otherwise specified, all data is based on our technical design parameters, laboratory test results, and supplier test data. Some data may be peak performance data. Actual performance may vary depending on software version, specific test environment, and phone model. Data is obtained from vivo's laboratory tests and refers to single-app operations/standby conditions only. Test environment: Ambient temperature 25°C±1°C.
  Test conditions: With the device 100% charged, screen off, volume at 63 dB, and Wi-Fi connected. Actual battery life may vary depending on usage habits, environment, and other factors.
• Data is based on tests conducted in our laboratory, referring only to single-application use/standby scenarios. Test environment: ambient temperature of 25°C ±1°C. Test conditions: device fully charged, screen brightness set to 150 nits, volume at 63 dB, connected to Wi-Fi. Actual battery life may vary depending on usage habits, environment, and other factors.

• Based on vivo lab tests, battery retains more than 80% of its capacity after 1600 full charge cycles. These tests simulate average daily use (charging once every 1.23 days), and results show that 1600 charge cycles are approximately equivalent to 5 years of use. The above data is provided by vivo labs based on tests conducted in a simulated environment, with an ambient and battery temperature of 23°C±2°C and full charge/discharge cycles. Actual results may vary due to differences in test equipment, the test environment, and personal usage patterns and habits. Europe has energy efficiency label regulations that require battery cycle count to be indicated on energy efficiency labels. This rule is pending confirmation after internal company alignment.
• Y21d supports up to 44W FlashCharge with a vivo official vivo 11V/4A charger. Actual charging power dynamically adjusts based on usage conditions.
• Charging data is derived from vivo laboratory tests. Test environment: ambient temperature 25℃±1℃，with 1% of batter capacity. 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.
• IP69 test conditions: ① Turntable speed: (5±1) r/min; ② Nozzle angles: 0°, 30°, 60°, 90°; ③ Water flow: (15±1) L/min; ④ Water temperature: (80±5) °C; ⑤ Test duration: 30s per position; ⑥ Device placement: vertical with USB port facing downward.
  IP69+ test conditions: Under the same parameters, the device undergoes three consecutive tests at the same placement angle.
  IP69+ indicates that this model meets the water-resistant standards of IP68 and IP69 and has passed three rounds of IP69 water resistance tests. It is not a professional waterproof mobile phone, but it is water- and dust-resistant under normal use. The actual experience shall prevail.
• 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 fresh water up to 1.5 meters for up to 30 minutes, with a temperature difference between the water and the device of less than 5°C. 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 down. This product is not a professional water-resistant phone. The resistance to splashes, water, and dust is not permanent and may be reduced with 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 warranty.This device is not suitable for diving or swimming.
• This product has been tested on samples under controlled laboratory conditions and meets IP68 and IP69 standards. Actual performance may vary under real-world conditions. The splash, water, and dust resistance is not permanent and may diminish over time. The device is not suitable for activities such as swimming, diving, surfing, rafting, hot showers, or saunas, and such usage should be avoided. Do not charge the phone when it is wet; clean and dry it immediately. Damage caused by liquid ingress is not covered under warranty.
• The resistance to water is not permanent and may be reduced with daily use. Do not charge the mobile phone when it is wet. Refer to the user manual for cleaning and drying instructions. Please avoid damage caused by liquid ingress.
• This product is tested under controlled laboratory conditions. As a precision electronic product, the phone still carries a risk of damage from drops. Please be careful to avoid drops and collisions. Any damage caused by improper handling is not covered under warranty.
• These laboratory test results do not serve as a definite indicator for quality assurance during daily usage. The precise outcome might differ slightly depending on the test software version, specific testing environment, and the particular version involved.  Please refer to the actual usage.
• Data comes from vivo labs.
• Data is based on results from vivo’s sandpaper drop tests.
• 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.
• The Circle to Search with Google feature requires an internet connection and is available on the 8 GB RAM edition only.

• The AI Screen Translation feature requires an internet connection.
• 400% Volume is limited to speaker output and does not apply to earphone playback.
• Measured diagonally, the screen size is 6.68 inches in the full rectangle. Actual display area is slightly smaller.
• High brightness mode (HBM) is automatically enabled when the ambient light intensity exceeds 10,000 lux and the phone is set to Auto Brightness mode, at which point HBM increases the screen brightness to 1000 nits. This feature provides users with a better experience in environments with intense light. When the ambient light falls below 10,000 lux or the phone heats up, HBM is automatically disabled to save power.
• The product has passed TÜV Rheinland Low Blue Light Certification under conditions with Eye Protection enabled at the setting of highest intensity. This product is not a medical device and does not have any therapeutic functions.
• The pixel value may vary in different camera modes, and is subject to actual usage.
• Please use the water resistance feature under official testing conditions. Avoid using the phone in non-freshwater environments; take photos underwater at a maximum depth of 1.5 meters for no more than 30 minutes at a time; after using the phone underwater, remove the phone, wipe dry, then long-press the corresponding button on the screen to exit underwater mode and eject water; dry the phone in a ventilated, dry environment; do not charge or connect external devices until the Type-C port is completely dry; avoid drying the phone with heat sources such as hair dryers. Note: Due to temperature differences and humidity, lens condensation or fogging may occur when the phone enters water. Typically, leaving the phone in a stable, low-humidity environment for about 20 minutes restores clarity. Damage caused by liquid ingress due to not following the water-resistant testing conditions is not covered under warranty.
