Mobile phone battery power and then recharge the battery better? Dec 23, 2017

Each time you buy a new cell phone, the cell phone battery inside all the "power" light, and then carefully for the first "charging ceremony", I heard that this will not hurt the cell phone battery, so that the phone can be a long, long time We serve. However, the recent purchase of mobile phones, friends say that this "cell phone with the photoelectric charge" is out of date?


Koko asked his friends and found that people disagree on this statement. So today, Keke Jun just talk to you in the end whether to use light cell phone battery, recharge?


Recharge with light, which is already veteran of the "nickel-cadmium batteries"


In the 1990s, the "nickel-cadmium batteries" assembled in cell phones made an unwritten rule in the "phone's manual" that the battery was drained after it was recharged, otherwise the capacity of the battery would drop .


In fact, this is because of the "memory effect" of nickel-cadmium batteries. Nickel-cadmium batteries have a characteristic, that is, in the discharge (cell phone use) process, if the battery power is not completely depleted, recharge the battery plate when there will be a lot of "small bubbles." In so doing, these bubbles reduce the reaction area of the battery plate and allow the battery's capacity to drop. Like a nickel-cadmium battery "remember" the shortened battery life, so that the charging cycle is also shortened, the battery capacity becomes smaller and smaller.

In addition, cadmium has some toxicity, is not conducive to environmental protection, so the basic nickel-cadmium batteries have been eliminated from the "digital equipment battery" circle.


Modern cell phone, want to charge to charge. This depends entirely on "lithium polymer battery."


Nowadays, most of the batteries we use on our mobile phones are "Lithium Polymer Batteries". The batteries can be fully charged and fully charged before they can be used for 2 ~ 3 hours.

Lithium-polymer battery is not like nickel-cadmium batteries have a "memory effect", its life is based on the "charge cycle" to decide. This battery is a reusable garbage bag, it can guarantee the rubbish 500 times, this bag is not damaged; more than 500 times, the garbage bag will be thinned, it can only hold the previous 80% More loaded hundreds of times, may only be installed before the 40% ~ 30%.


However, the "charging cycle" that determines the life of a cell phone battery now does not equal "number of charges." A charge cycle, means that we have to run out of all the electricity inside the battery. That is to say, if the phone had 70% of the charge the day before, it was fully charged. The next day it used 30% of the charge and was fully charged. We did not consume 2 charge cycles and only consumed 1 charge cycle.


Charging the phone one night, the battery is not good?


The phone has been charging, the impact on the battery is not large. After the phone is fully charged, the phone will also consume some of the standby power while the phone is on standby. In this case, the charger will use "micro-current" to compensate for the battery power loss, but this will not "overcharge" the battery. Once the voltage and current abnormal phenomenon, mobile phones and chargers will start the "protective measures", automatic power-off, to avoid accidents.


Too cold, too hot, the phone automatically shut down is how the case? Mobile phone battery "low temperature protection" function ...


I believe many people have encountered in the winter to take out a fully charged cell phone, the result was useless for 20 minutes, the battery declared no power off problem. In fact, this is the cell phone's "low temperature protection." When the weather is too cold, it is very difficult for the lithium ion to be embedded in the electrode, which will cause the lithium ion battery to be deposited (lithium metal is deposited). Therefore, the mobile phone will fall into the automatic shutdown state at this time to prevent the battery from being damaged. This time if the compulsory charging, it is likely to cause the battery short circuit, so in order to protect the battery, it is best to wait for the phone "warm" back to the temperature, then recharge it.
