The "legends" about batteries are everywhere, such as the first three times charging needs to be over 12 hours, you cannot answer phone while charging, it's best to use lithium battery until automatic shutdown... In fact, these statements are often wrong and make no sense. Portable design is supposed to make our life easier, but issues regarding battery life force us to take good care of it - is it really necessary?
Legend one: the first three times charging needs to be over 12 hours
