This is a standard industry parameter for lithium-ion batteries, and it is closely related to the actual battery endurance of your vivo mobile.
During the mass production of mobile phone batteries, it is technically impossible for every single battery cell to have exactly the same capacity. Minor differences in raw material characteristics, production procedures and manufacturing precision will lead to slight normal variations in the actual capacity of each finished battery, which is a common phenomenon in the global battery manufacturing industry.
The rated value (marked as min) of battery capacity refers to the minimum guaranteed capacity of the battery. In other words, every battery installed in a factory-qualified vivo smartphone will have an actual capacity no lower than this officially published rated minimum value.
This indicator serves as a unified factory quality benchmark, ensuring that all delivered vivo mobile devices can meet the officially declared battery life and performance standards.
For daily use, there is no need to worry about these tiny capacity differences. The actual battery endurance of all qualified devices will reach or exceed the level corresponding to the rated capacity, and will not affect your regular daily charging and usage experience.
