All you need to know about charging a smartphone battery

Owners of technology that uses lithium-ion batteries are completely confused with scattered, confusing, and often contradictory information about charging batteries. How to properly charge a smartphone battery - this article contains comprehensive information on this issue, based only on verified data.

Proper charging of the smartphone battery will increase the life of the phone.

What is the battery for and how does it work

In order to know how to properly charge the phone battery, you need to understand how it works.

The function of the battery is to supply the smartphone with the necessary electric current for its operation. During this supply, the pre-accumulated capacity from the battery goes into the device (consumed). After some time, the battery voltage drops to a level that the telephone cannot maintain.

Then the controller comes to the rescue of the battery, which saves the battery, turning it off and not letting it “go to zero”. That is, not to die. Together with the disconnection of the battery is disconnected and devoid of power device. To restore the working condition of the battery, it must be charged again, filling its capacity. Thus, the life cycle of a Li-ion battery consists in the periodic accumulation of charge and its transfer to the powered device.

In addition, there is another period of life - when the battery does not charge, and does not give energy outside, but is simply stored (on the shelf of the warehouse or on the shelf of the cabinet in the apartment). All these periods (each separately) are characterized by their own rules of use and the associated operating parameters.

In this article, we are primarily interested in the stage of "charging" the battery. But it is necessary to speak about it in the right way with an eye on both “work” and “storage”.

Rules and options

The rules and parameters, the observance of which is necessary for the full use of the battery, can be divided into two categories - on which the user has an impact and on which can not influence. However, they are closely related. Therefore, we consider them in the complex.

Voltage and Controllers

Battery capacity is characterized by the voltage that it supplies to the phone. As a rule, its value ranges from 2.7 V (minimum) to 4.2 V (maximum). This corresponds to a charge from 0 to 100 percent. Of course, anything below 2.7 V is also a charge in the physical sense. But the battery controller takes this value as zero and turns it off.

After turning off the internal chemical processes do not stop - the discharge of the battery continues, but passes more slowly (called self-discharge). Even later, the “deep discharge” phase begins. Deep discharge can also occur during cooling (in the cold) of a “zero” instrument.

The battery in this state will not be seen by another controller, located in the phone itself, and controlling the inclusion (start) of the charging process itself.

Therefore:

Rule 1:

Start charging the battery without waiting for the phone to turn off and (moreover) without bringing it to a deep discharge.

Rule 2:

Remove the discharged battery from the freezing environment immediately.

Amount of charge and durability

It is known that the longest life of a Li-ion battery is achieved if it operates with a charge of forty percent of its nominal value. The same value is adequate for its storage (with such a charge, the batteries are sold!). The greater the deviation from this figure, the more shortened their lifespan. One-time reduction is barely noticeable, but over time, small values ​​add up.

From here:

Rule 3:

Do not be afraid of frequent small charge - it can not hurt. And in principle, it is better than charging from 0 to 100%.

Rule 4:

Keep the device charged at 40–45 percent power at a temperature of plus five degrees. (In this condition, it does not require attention until six months).

Danger of overcharging

In contrast to the deep discharge, sometimes the phenomenon of overcharging occurs, to which lithium batteries have a lower resistance and after which they can work incorrectly. This can happen if you heat (in heat) a hundred percent charged device. Overcharging leads to further heating of the “can”, increased pressure, bloating and other dangerous consequences.

Consequently:

Rule 5:

Avoid frequent charging up to 100% power. When reaching one hundred percent remove the device from the outlet.

Rule 6:

Do not charge or hold the device near heat sources.

Lack of memory

A distinctive feature of lithium nickel batteries is the lack of a “memory” effect, therefore:

Rule 7:

The initial two-three-time training of the purchased device does not make sense - it is enough just to carry out a full charge-discharge once to calibrate an additional controller.

Important notes and cautions

In addition to the above, you should point out some points that will help avoid possible errors or troubles when using the smartphone battery:

  • When the device is moved to conditions of reduced atmospheric pressure, there is an increased decrease in capacity compared to normal conditions;
  • The fifth charge is no different from fifty-five;
  • When working in the cold, Akum loses up to half its power;
  • “Fast” charging is harmful to the battery;
  • Do not leave the charging device unattended;
  • To "save" the battery, you can use a portable charger;
  • Charging must be done using the recommended chargers;
  • During operation, follow the instructions supplied with the device.

Now, using the knowledge of how to properly charge a smartphone battery, and understanding other problems related to this, you can extend the service of your device. As they say, serve things once - she will thank you repeatedly with her service.
