Ruichi does the phone business more than 5 years, here is some tips for you to make the distinguish for the different battery from our rich experience.

The main difference between a standard battery and an extra capacity battery is the amount of energy they can store and provide. An extra capacity battery typically has a higher energy density, which means it can hold more energy in the same physical size as a standard battery. For example, if a standard battery can store 3000mAh of energy, an extra capacity battery of the same size might be able to hold 4000mAh or more. This means the extra capacity battery can power a device for a longer period of time before needing to be recharged. However, an extra capacity battery may also be physically larger and heavier than a standard battery, which can affect the overall size and weight of the device it's used in. Additionally, an extra capacity battery may be more expensive than a standard battery, depending on the technology used to increase its energy density. Overall, the choice between a standard battery and an extra capacity battery depends on the specific needs of the device and the user. If longer battery life is a priority and the device can accommodate the larger size and weight, an extra capacity battery may be the better choice. But if size and weight are important factors or the device doesn't require extended battery life, a standard battery may be sufficient.
