Is it a problem that you can't fully charge?What is a charging care function that prevents smartphone batteries from deterioration?

In order to prevent the battery deterioration of the smartphone, the iPhone and some Android smartphones have added a battery care function to "stop the battery by stopping the charging on the way."On the other hand, the battery deteriorates, but since the charging stops on the way, the number of inquiries at the customers of the manufacturers and mobile companies saying "Is it not possible to fully charge but it's a problem?"Explain how to get along.

What is charging to prevent battery deterioration?

Smartphones have a function to suppress the deterioration of the battery and extend the battery life.For example, in the case of an iPhone, it is a function to reduce the deterioration of the battery by charging up to 80 % and slowly charging the remaining 20 %.Even with similar functions, the names and details differ depending on the model, so let me introduce some typical battery care functions.

iPhone (iOS 13 or later): Optimized battery charging

A function added after iOS13, a function in which the iPhone learns the tendency of daily charging, reduces the deterioration of the battery and extends the life of the iPhone as much as possible.If you turn it on, the charging speed of 80%or more will be slower, so it may not be fully charged even if it is charged all the time, but it is not a failure.

This function is turned on with the initial setting when purchasing iOS 13 compatible iPhone.Also, if you update the iPhone you are using to iOS 13, it will automatically turn on, so after the OS update, it seems that it will not be fully charged even if you charge it as usual, and it may be mistaken for a defect.。

"Optimized battery charging" works only when the iPhone knows the tendency of daily charging by machine learning and is expected to be connected to a charger for a long time, but people who are worried.Let's turn off the function.

■ How to set up "Optimized battery charging" Settings "Settings" → "Battery" → "Battery status" → "Optimized battery charging" switches ON/OFF

Even in the case of setting ON, if the lock screen has a display of "Notification to notify when the iPhone will be fully charged", you can start charging over 80%by pressing and tapping "Charging now".It is good to use it well according to your own application.

Xperia 1, etc.: Charging

A function to learn charging habits, such as when charging for a long time, adjusts the charging speed, maintains the performance of the battery in a better condition, and extends the life.Up to 90 % is charged at the same speed as normal charging, the charging is stopped until 90 % or more until the fully charged target time, and the charging resumes to be fully charged by the time as the target time approaches.

There are "Automatic settings" and "manual settings" in the settings.You can select "manual setting" to set the time of.

■ How to set up "Design Charging" (example of Xperia 1) "Settings" → "Battery" → "Charging Charging" Switch ON/OFF with the upper right button

TORQUE G04, etc.: Battery care mode

A function to stop charging at 85%to prevent battery deterioration.When turned on, a heart mark is displayed on the battery icon.In a state of 86%or more, it will not be charged until 85%at a time, and 85%will always have a charging upper limit, but it can be used for a long time with less load on the battery.

■ Setting method of "Battery Care Mode" (example of TORQUE G04) Switch ON/OFF in "Settings" → "Battery" → "Battery Care Mode"

What are the deterioration factors of lithium -ion batteries?

Let's review the lithium battery here.The lithium -ion battery, a smartphone battery, is a consumable item, and the more used it is used, the more the battery performance deteriorates, and the battery life is worse than the new one.The main "deterioration factors" and "factors to accelerate deterioration" are as follows.

■ Deterioration factor ・ Cycle deterioration

■ deterioration acceleration factor ・ Use at high temperatures and low temperatures

In this way, it is desirable to avoid deterioration and acceleration factors in order to prevent battery deterioration.There are three points to prevent battery deterioration.

(1) Do not charge unnecessary repeated charging (prevent cycle deterioration) ② Do not maintain a low battery level or full charging state for a long time (prevent conservation deterioration) (3) Avoid the use at high temperature and low temperature (prevent acceleration factors due to temperature.)

Among them, battery care functions have begun to be installed to prevent preservation deterioration.

Charging that makes the battery last longer

Now that smartphones are becoming a daily necessity, the charging care function that prevents the battery deterioration is a very nice function to use as long as possible.However, for those who want to be fully charged, updating without knowing may misunderstand it as a problem.

Those who want to be fully charged even after knowing the risk of battery deterioration can be used properly, and those who want to prevent it from deterioration are turned on.I want you to use it well.
