What is the general know how related to better battery life?Currently, many digital devices run on a battery that can be recharged once it gets discharged. There are certain know-how if followed can be good for the battery life. There are many myths available in the market regarding battery performance and life. I want to know, which is the correct one. As far as I know, each battery comes with a fixed charging and discharging cycle. Once you totally charge and discharge, the cycle is over and it will be having one cycle less battery life remaining. I have read that, to get rid of this, one has to use the battery from 20 % to 80 % only. That means, If the battery level is around 20 %, one should charge it up to 80 % level, not more than 80 %. Do not charge beyond 80 %, else total or fully charged battery will reduce one more cycle from the battery life cycles.
