How do you charge mobile phone correctly?

Normally people charge their batteries up to 100%. After a while, they will re-saturate and unplug the line, but you know what? After using mobile phones for so many years, it turns out that this recharging way is wrong! 

Usually these charging concepts are wrong.

1. The life of the battery related to the number of times of charging, so it needs to charge to 100% each time.

2. Less than 15% of the low battery will not charge, so that the maximum amount of power per charge

3. Try to control the frequency of use of the phone every day to ensure that only one charge charged per day.

The purpose of our charging: First, extend the use of mobile phones. The second is to extend the service life of the mobile phone battery itself. To achieve these two objectives, the following points need to note.

"Battery Academy" theory

This charging is good for the battery.

1 It is best not to fill the battery

According to the battery school, lithium batteries (now smartphones are basically such batteries) do not need to be fully charged, and it is best not to be completely full, because the high voltage (the voltage will rise after being filled) makes the battery itself bigger. Pressure, in the end, will have an impact on battery life.

For extending the battery life of the mobile phone, the best time to pull out the charging cable is the end of step 3, the charging power displayed at this time is about 80%.

2 The battery should charge and the power cord should remove immediately.

Many people have the habit of charging at night, and the power cord pulled out the next morning, but this approach is not good for battery life.

Understand the above principles; this is not difficult to understand. Because your phone is always 100% fully charged, the battery is always at the highest voltage, which is not good for the battery - if you pull out the power cord when you are full, there is no such problem, because the power is unplugged After the line, the voltage inside the battery will continue to weaken.

3 If possible, charge as much as possible

It is said that the life of the battery is related to the number of times of charging, which is wrong.

The life of a lithium battery measured by the charging cycle. The so-called charging cycle refers to the process of charging all the battery from full to empty and then from empty to full. If you have a 1000 mAh battery, you will fully charged after every 100 mAh, and then you have to charge 10 times to calculate a charge cycle (100 mA times 10 times).

Regardless of feasibility, just from the chemical point of view, charging the primary battery is the best way (the charging efficiency is the highest) whenever the mobile phone battery consumes 10% of the power (for example, the power is reduced from 60% to 50%).

4 Keep the battery cool

If temperature too high, it will also affect lifetime of mobile phone battery. Many mobile phones become a little hot when charging. In this case, you may need unplug the power cord and let the battery cool down before continuing to charge.
