Resetting your battery level back to how it was made in the factory is one perfect way of extending battery life and performance. Please note that, do this once / twice a month, failure to adhere may lead to weak/dead batteries.
Steps;
1. Drain device battery completely, by allowing it to reach 0% then it automatically shuts down.
2. Plug in your charger, don’t put the device on until it’s fully charged.
