New cell phone batteries need to run out of electricity after it？

Previously said that the need to completely re-charge the phone battery recharge more than 10 hours is the correct use of nickel batteries corresponding to the norms.
Nickel cell phone batteries are now basically eliminated by the market, the market mainstream are generally lithium batteries.
Buy a new lithium battery does not need to follow the norms of the use of nickel batteries, but rather if completely exhausted and then recharge the phone battery life impact.
And it should be noted that most of the new lithium battery sleep, the first three charges can only play 80% efficiency of the phone battery charge after several times on the OK!
How to charge the new battery
In the use of lithium batteries should be noted that the battery is placed in a dormant state after a period of time, when the capacity is lower than normal, the use of time also will be shortened. But the lithium battery is very easy to activate, just after 3-5 times the normal charge and discharge
Electric cycle can activate the phone battery, restore normal capacity. Due to the characteristics of the lithium battery itself, it has almost no memory effect. Therefore, the user's cell phone in the new lithium battery activation process, does not require special methods and equipment. Not only is it theoretically true, from my own point of view, it is best to charge this "natural activation" method from the very beginning with standard methods.
For the "activation" of lithium batteries, many say: the charging time must be more than 12 hours, repeated three times in order to activate the phone battery. This "the first three charges to charge more than 12 hours," saying, obviously from the nickel batteries (such as nickel-cadmium and nickel metal hydride) to continue. Therefore, this argument can be said that the beginning is a misrepresentation. Charge and discharge characteristics of lithium batteries and nickel batteries are very different, and can tell you very clearly, I have reviewed all the serious formal technical information have stressed that overcharge and overdischarge will be on the lithium battery, especially the liquid lithium Ion batteries cause huge damage. Therefore, the best charge according to standard time and standard method of charging, especially not for more than 12 hours of long charging. In general, the charging method described on the phone's manual is a standard charging method suitable for the phone.
In addition, the lithium battery cell phone or charger will automatically stop charging when the battery is full, and there is no "trickle charge" that nickel-based chargers call for 10 hours. In other words, if your lithium battery is full, on the charger is white fill. And none of us can not guarantee that the battery's charge-discharge protection circuit will never change its characteristics and foolproof quality, so your battery will be hovering for a long time at the edge of danger. This is another reason why we oppose long charging.
In addition, on some mobile phones, charging more than a certain period of time, if you do not remove the charger, then the system not only does not stop charging, will start the discharge - charging cycle. Perhaps the manufacturer of this approach has its own purpose, but apparently unfavorable for the life of batteries and cell phones / chargers. At the same time, long charging takes a long time, and often needs to be carried out at night. According to the situation of China's power grid, the voltage in many places is relatively high at night and fluctuates greatly. As I have already said, lithium batteries are very delicate. They are far less capable of fluctuating than nickel batteries in terms of charge and discharge, which adds additional dangers.
In addition, another aspect that can not be ignored is that lithium batteries are also not suitable for overdischarge. Overdischarging is also disadvantageous for 
the correct approach to the lithium battery phone

To sum up, my most important tips for charging and discharging lithium-ion mobile phones in use are:

1, in accordance with the standard time and program charging, even if the first three times have to be so;

2, when the phone is too low tips, it should try to start charging in time;

3, the activation of lithium batteries do not need special methods, the normal use of lithium batteries will be activated naturally. If you insisted on using the popular "first three 12-hour long charge activation" method, in fact, will not be effective.

Therefore, all the pursuit of 12 hours long charge and the lithium battery phone to automatically shut down the practice is wrong. If you have done so in the wrong words, you may correct it in time, perhaps not too late.

Of course, in the mobile phone and the charger itself to protect and control the circuit quality is good, the protection of the lithium battery is still quite guaranteed. So the understanding of charging rules is the point, in some cases it is possible to make some concessions. For example, if you find that the phone must be recharged before you go to bed at night, you can also start charging before going to bed. The crux of the matter is that you should know what the right thing is and do not do it in the wrong way.
