As you know, mAh measures the battery capacity. It means that a battery with a higher mAh rating can hold more charge, and thus, it can power a device for longer. Apart from battery mAh, there are a couple of other factors that affect the battery life. They include the usage patterns, battery age, and power consumption of the device.
The relationship between mAh and battery capacity is straightforward. A battery with a higher mAh can store more energy. For instance, a 2000 mAh battery can provide 2000 milliamperes of current for one hour or lesser current for a longer time. The mAh rating is vital for devices requiring sustained power, like smartphones and laptops.
To calculate the electric energy stored in a battery, multiply the battery’s charge capacity C (in Ampere-hours) with its voltage V. Since the voltage V is always clearly specified, we know how much that is. And the charge capacity C (in Ampere-hours) is also typically specified.
