What is mAh?

mAh refers to the capacity of storage a battery has. It stands for “milliampere hour”. The level of mAh really tells you how long a battery will last. Typically, a battery with a higher mAh will last longer. However, if only life were this simple. There are an array of factors to consider when looking at battery life. Like your phone battery, the more you use it and the way in which you use it, will effect how long a battery lasts.
