A fairly frequent custom among smartphone users, whether Android or iPhone, is that most of them usually let their smartphone’s battery reach 0% to just start charging it. You may not know it, but this practice is not recommended for your cell phone and here we are going to reveal the reasons.

As detailed by Xataka, the habit of draining the entire battery has been going on for several years, when these components were made of metal or nickel. To take care of them and that they last for many years, experts suggested that users wait for the energy to run out completely before putting it on charge.

In this regard, to extend the autonomy that smartphones can offer, scientists from the University of California designed a battery that can withstand 200,000 charging cycles, equivalent to 400 years of use.
