FAQs
Disclaimer
Product images are for illustration purposes only and actual product appearance may vary slightly.
Usable RAM and storage are less than stated, because the operating system and pre-installed apps use part of them. Extended RAM is a software feature and does not add physical memory.
Battery life and charging times are vivo lab figures; actual results depend on usage, settings and temperature. The typical battery capacity is 6500 mAh and the rated capacity is 6355 mAh.
The battery health figure (more than 80% capacity after 1,600 full charge cycles) comes from vivo lab tests in a simulated environment.
IP68 and IP69 are lab ratings under IEC 60529. The resistance is not permanent and may wear over time. Use the underwater mode in fresh water only, no deeper than 1.5 metres and for up to 30 minutes at a time, and dry the USB port fully before charging. Liquid damage is not covered under warranty.
The 120Hz refresh rate works only in apps and games that support it.
Some AI features need an internet connection and may change with software updates.
5G needs a 5G plan and network coverage from your operator.
