Mobile phone is not full to use it?
The battery remaining power used up the principle of recharging is not to the extreme. And long charge as widely circulated a saying, is "as far as possible the battery life of mobile phones, it is best to use automatic shutdown." This practice is actually only nickel batteries on the practice, the purpose is to avoid the "memory effect" occurred, unfortunately this is also circulating in the lithium battery today.
Abnormal time charging and full use of empty electricity will cause overcharging and over-discharge, will cause permanent damage to the positive and negative of lithium-ion battery, from the molecular level, the excessive discharge will lead to excessive release of lithium ions in the negative electrode Layer structure collapse, overcharging will be too much lithium-ion hard into the negative carbon structure to go, leaving some of the lithium ions can no longer be released. This is why lithium-ion batteries are usually equipped with charge and discharge control circuit reasons.
Or follow the slogan of lithium battery inventor "that is charged, that is," the use of lithium batteries.
Mobile phone battery charging is not necessarily filled, lithium battery life is mainly reflected in the charge and discharge cycle, this cycle is an absolute concept, the last use of 30% of electricity, full of electricity, the next use of 70% of the electricity, and full , This is just a charge cycle.
