The usage duration of a 4400mAh battery cannot be directly determined as it depends on the power consumption of the device.
The analysis is as follows:
The relationship between battery capacity and power consumption: The milliampere hour (mAh) of a battery represents the amount of electricity it stores, but the actual usage time of a device also needs to consider its power consumption (i.e. the amount of electricity consumed by the device per unit time).
Variable factors: The power consumption of a device varies depending on factors such as device type, screen brightness, and running applications. For example, the power consumption of smartphones is usually higher than that of smartwatches.
Therefore, to accurately determine the usage duration of a 4400mAh battery, it is necessary to know the power consumption of the specific device.
