Have you ever felt that the battery of your mobile phone or camera must be constantly recharged after a short while? This is actually because the performance of the battery reduces over time. Here are some power-saving measures for you to try out, so that you can prevent it from happening. With this, even smartphones can stay powered up for awhile longer. To improve the performance of the battery slightly better on your own: just simply charge and discharge the battery in repeated successions within a short time. Be sure to always completely discharge it but simultaneously do not leave it for the whole day or else it will total discharge and that could possibly make the battery unusable permanently. This tip is particularly handy for devices, whose batteries are not compatible or have already lost massive amounts of running time due to frequent short time charging.
