What are the benefits if we completely discharge battery of mobile phone every month?

As we all know, mobile phone tends to use lithium-ion battery, and the battery has no memory effect, so you can charge it at any time when you use it. You don't need to wait for run out of power, which is more likely to damage battery.

So what else is there to say? Can the article end?

In fact, the above two seemingly contradictory statements are not contradictory. Of course, this also based on some foundation.

For the new point of view on the Internet: It is not correct to put the battery on the mobile phone battery every month. The complete discharge here means that the battery power is 10%-20%, not to say that the battery is 100%. When you run out and even use automatic shutdown, you should first understand the concept of this setting.

Based on this concept, it is good for the mobile phone to put the battery of the mobile phone once a month.

Want to know why, we must first understand how the phone counts the lithium battery.

Lithium batteries will have a power detection chip. This chip will record the complete charge and discharge curve of the battery according to the formula (voltage, current, time). After repeated use, this curve will gradually change with our bad charging habits, but when the chip is calculated, it will still follow the initial curve, so there will be errors.

That is to say, as the battery ages, in fact, the actual available power of the mobile phone may be less and less. and there will be a situation in which the display power of the mobile phone does not match the actual available power, that is, the mobile phone display may be fully charged, but the actual display is not full, so We will feel that the battery is getting less and less durable. This is actually the battery display is not accurate and needs to be calibrated.

Calibration is nothing more than letting the chip recognize the change in the curve and re-giving a new formula for calculation. That is, it is necessary to completely discharge the battery once and let the chip recalculate the curve.

Every time it discharged, the system will judge according to the battery power, whether it needs to update the curve, update the actual available power, keep the displayed power and the actual available power consistent, and avoid the battery display is not accurate.

The calibration method is also very simple, that is, the mobile phone is completely discharged once, but this complete discharge does not require the automatic shutdown of the mobile phone (which will damage the battery), but when the mobile phone power is maintained at 10%-20%, To charge the phone.

Previously, the professor also said that the best charging time for mobile phones is 30%-50%+ of the remaining power, so many people may get used to it. When half of the battery is charged, the phone will charged. Discharge completely.

In summary, back to the beginning of the question, so that the battery completely discharged once a month, it is indeed good for the battery. It's just that the complete discharge here is to keep the phone's power at least 10%, preferably not less than 5%, otherwise it may be counterproductive.

What is your charging habits like? It is with charge or charge it every time when you notice it is not full? Are you waiting until battery is running out?
