Dominik Schulte, director of the German company "BatterieIngenieure", said that a smartphone user who leaves it overnight and disconnects from charging after it reaches 100% reduces battery productivity.
According to the expert, smartphone battery productivity decreases more slowly at a charge level of 5-30%. At the same time, it is advised to charge devices, for example, in the morning.
According to Business Insider, all lithium-ion batteries are somehow subject to "aging" due to changes in chemical composition and thus have a limited service life. In addition, your interest in the smartphone battery may not have any noticeable effect if the device is changed every two years or less.
Earlier, the Russian agency "Sputnik" quoted the head of the technological site "Hi-Tech Mail.ru", Dmitry Ryabin, saying that charging the smartphone 100%, as well as discharging the entire battery, reduces the battery life.
