Now most people think, buy a new phone to "activate" the phone's lithium battery. Many cell phone salesman will give you the first time to charge more than 12 hours, and then run it flat, then charge 12 hours, repeated a total of three such phones lithium batteries in order to be complete "activated."
In fact this "the first three charge must be sufficient enough for 12 hours," the statement obviously is a continuation from the early nickel batteries (such as nickel cadmium and nickel metal hydride) down. Modern mobile phone industry has basically been turned to the use of lithium batteries, lithium batteries with nickel batteries have completely different properties. Therefore, this argument is clearly placed on the lithium battery a mistake. Charge and discharge characteristics of lithium batteries and nickel batteries have a very big difference, and can very clearly say, overcharge and over discharge lithium batteries, especially lithium liquid ion battery causing great harm.
Therefore, in accordance with standard lithium battery charging time and should be the standard method of charging more than 12 hours of super-long charge the battery but no good. New battery individual statement introduced mobile phone charging must be more than twelve hours of argument it is wrong. So for the new phone just like we use every day, like the charge on the line, the phone charge indicator shows the battery is full, you can stop the charge.
In addition, most of the lithium battery cell phone charger when the battery charger will automatically stop the charging. There is no presence of the nickel charger for 10 hours, "trickle" charge. On the contrary, if the number of mobile phone charging constantly open the charger, this charger does not stop charging more than a certain time, but also into the discharge - charge cycle. Clearly this approach in terms of battery life is harmful. Of course, do not ignore another aspect, the lithium battery is the same and should not be over-discharge, over-discharge of lithium batteries can also cause permanent damage.
The correct charging method should be: Do you expect the first two days of mobile phone batteries can not persist throughout the day, when they should phone the previous night to a full charge, but do not run out of electricity until turned off before charging. This means you should expect to phone in advance to prepare sufficient power, usually in days time unit. Therefore, even if there are a lot of battery power over, but not be able to stick to the next charging time, then you should be charged in advance. This does not lose a single charge cycle life. Remaining battery power runs out the principle of charging not want you to go to the extreme.
And long, like charging widespread a statement is: as far as possible the cell phone battery runs out, it is best to use automatic shutdown before charging. This approach is correct on nickel batteries, the purpose is to avoid battery memory effect occurs. This statement does not apply to lithium batteries. Because it will cause excessive discharge of cell phone lithium battery, it will cause low voltage, so do not have the normal charge and the boot and conditions. Actual experience shows: 100% depth of discharge of lithium batteries scrap rate of 50%, over the years proved only half the depth of discharge of more than 99% of lithium servicing power supply can be activated, and the other half scrapped.
