In real life, people are always thinking about going full or full after two or three times with a new cell phone or other digital gadget, and the phone lasts longer, and the fact is often the opposite, as the phones used today Are lithium-ion batteries, so there is no such problem.A US electronics engineer 'Tom Hartley' said, 'lithium batteries put more discharge, the greater the loss of the battery, the lithium battery is best in the middle of the charge State, so the longest battery life '.
The cell phone is too high or too low state of charge have a negative impact on the life of lithium batteries.Experiments have shown that for some laptop lithium batteries, often let the battery voltage exceeds the standard voltage of 0.1 volts, that is, from 4.1 volts to 4.2 volts , Then the battery life will be halved, and then increase 0.1 volts, the life reduced to one-third of the original long-term low-power or no battery state will make the battery internal resistance to the movement of electrons is growing, so lead Battery easily smaller.
Because of the excellent performance of lithium batteries, lithium batteries used in our daily lives do not need to be fully charged lithium batteries, not to use the power depleted in the circumstances permit, try to make the lithium battery power Maintained to half full state near the charge and discharge the smaller the better
