What’s the difference between a 100mah and 500mah battery?

Power draw is controlled by the device and not the battery and the two are usually matched to deliver a decent operating time between charges combined with adequate power for the device. A low power device that requires only 100mAh will last five times longer than a device that requires 500mAh.
