• 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, 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.

This product is not a professional waterproof 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.
• "Wet-Hand Touch" means that in typical everyday scenarios, the screen remains responsive to basic operations such as tapping and swiping even with wet fingers. Touch sensitivity may vary depending on the liquid type, coverage area, and wetness degree. The sensitivity may not remain consistent in all wet conditions. For the best experience, it is recommended to keep the screen and fingers clean. Actual touch response may vary.
• 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 is obtained from vivo laboratory. This product uses twice-reinforced glass, with a median drop height increase of over 100% compared to once-reinforced glass in 180-grit 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.
• Data is sourced from Qualcomm labs based on comparison with the last generation Qualcomm Snapdragon® 4 Gen 1.
• 50-Month Smooth Experience indicates that Y31s 5G has passed the 50-month smoothness testing in vivo lab test environments through an all-around technological optimization covering hardware and software. 50-Month Smooth Experience does not mean no latency at all. The actual experience may vary depending on the network environment, personal usage habits, and other factors.
• 8 GB extended RAM is enabled by software. The data is sourced from vivo labs.
• The 256 GB ROM edition is available only in some regions. The availability in each region depends on actual conditions. Actual available RAM/ROM is less due to the storage of the operating system and pre-installed apps.
• The Circle to Search with Google feature requires an internet connection and is available on the 8 GB RAM edition only. If Google icon appears in future promotions, please add the following note: The Google trademarks mentioned on these pages are owned by Google. Android is a trademark of Google LLC.
• The AI Screen Translation feature requires an internet connection.
• "Surround effect" refers only to descriptions in close-range scenarios. Data is based on tests from vivo laboratories, with Y39 5G used as the comparison model. Overall signal improvement refers to enhancements across the device's TOP 8 frequency bands. Maximum single-band improvement refers to the frequency band with the greatest gain among all tested bands, which in this case is the B40 right-hand TIS improvement value, based on vivo lab data.
• 400% Volume is limited to speaker output and does not apply to earphone playback.
• Measured diagonally, the screen size is 6.72 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.
• 120 Hz refresh rate works for apps/games that support 120 Hz.
• 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.
• The 4 GB RAM edition of Y31s 5G does not feature a front camera HD portrait mode.
• The Y31s 5G is not a professionally waterproof smartphone. The water-resistance scenarios shown above demonstrate the device’s water-resistance performance when it is new. Water resistance is not permanent and may diminish over time due to normal wear and usage. For underwater photography, the use of a professional waterproof housing is recommended.Please use the Underwater Photography feature only under official test conditions. Avoid using the phone in environments other than freshwater. When taking photos underwater, the maximum depth should not exceed 1.5 meters, and continuous underwater use should not exceed 30 minutes. After underwater use, remove the phone from the water and dry it thoroughly. Then, press and hold the designated on-screen button to exit Underwater Mode and expel any residual water. Place the device in a well-ventilated, dry environment and allow it to air dry naturally. Do not charge the device or connect external accessories until the USB Type-C port is completely dry. Avoid using hair dryers or other heat sources to dry the phone.Note: Due to changes in temperature and humidity, condensation or fogging may occur on the camera lens after the device comes into contact with water. In most cases, image clarity will be restored by placing the phone in a stable, low-humidity environment for approximately 20 minutes. Damage caused by liquid ingress resulting from use outside the specified water-resistance test conditions is not covered under warranty.
