• Data is obtained from vivo's laboratory tests and refers to single-app operations/standby conditions only. The test conditions for YouTube: screen brightness set to 150 nits, and volume at 63 dB, using Wi-Fi network. For Spotify: volume set to 300%, using Wi-Fi network, screen off. For navigation: screen brightness set to 150 nits, volume at 300%, using 5G network. Actual usage time may vary depending on such factors as test environment and other factors. Please refer to the actual use.
• Data is sourced from testing with AnTuTu Benchmark V10.4.4.
• Extended RAM is realized by software optimization.
• Actual available RAM/ROM is less due to the storage of the operating system and pre-installed apps.
• Data sourced from vivo lab tests. Compared to the Y300 5G, the 62%, 145% and 100% improvements represent low-frequency band data. Actual results may vary depending on software version, usage patterns, and environmental factors.

• This product is rated as IP65 for protection against dust and powerful water jets under IEC standard 60529 and was tested under controlled laboratory conditions. For more details on IP protection, kindly refer the actual IEC standard. The resistance to water jets and dust is not permanent and may be reduced over time by external factors such as daily use (such as SIM insertion and removal, drops, impacts). Do not charge the mobile phone when it is wet. Refer to Safety information in Settings for cleaning and drying instructions. Damage due to liquid ingress is not covered by 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 test environment, and the particular version involved.
• 50-Month Smooth Experience indicates that this device has passed the 50-month smoothness testing in vivo laboratory test environments through the optimization of software, hardware and other comprehensive technologies. However, 50-month smooth experience does not guarantee absolute freedom from lag. Due to differences in network environments, individual usage habits, and other factors, the actual experience may vary.
• Actual network availability depends on carrier network availability and infrastructure deployment. Data plan of Jio or Airtel carrier is required. For more details on 5G support, please contact your carrier.
