How to extend the battery life of the iPhone (1) | TECH+ Mynavi News Mynavi

iPhone 13 Pro Material: Apple

In this way, the iPhone is not a device that can be easily replaced, but sadly, smartphones are also consumables that definitely deteriorate.The more you use your smartphone, the more deteriorated.In particular, the battery is consumed and deteriorated each time it is used.If you use it incorrectly, you will feel that the battery has worsened in about two years, even if you use it normal.Furthermore, if you use it for a long time, it will deteriorate and you will not keep it for one day.

This is the physical characteristics of a lithium -ion battery, so it cannot be avoided.However, knowing the characteristics to some extent will allow you to extend your life, and you may be able to extend your life with a small setting.If you plan to continue using it for more than two years without replacing the battery, I think there is no loss in knowing the characteristics of lithium -ion battery and how to extend the life.

Use at a comfortable temperature for batteries

The battery used in the iPhone is a lithium -ion battery.Lithium -ion battery is an important battery that supports modern society used in various products, such as PCs, tablet devices, cordless home appliances, wireless earphones and speakers.

This lithium -ion battery knows the temperature that is likely to deteriorate.It is clear that deterioration progresses especially when used at high temperatures.Specifically, the temperature that humans feel comfortable is a comfortable temperature for lithium -ion batteries.

If you put your iPhone in the summer sunlight by direct sunlight, leave it on a car dashboard, or put it near the heating equipment in winter, the battery deteriorates.Spending the iPhone at a comfortable temperature like humans can easily increase the service life of the battery.

0 %, 100 %

Although lithium -ion battery has a characteristic that it can be charged at high speed and has a longer service life compared to the previous batteries, it may deteriorate when stored completely discharged or stored in 100 %.Are known.It is useless whether it is empty or full.This is the physical characteristics of a lithium -ion battery, so it can't be helped.

For example, many people connect to a connector before going to bed and have a battery 100 % when waking up in the morning.In addition, in some cases, if you are working at a desk, you may always be charged and keep 100%at any time except for carrying it.Mental, the iPhone battery is always 100 % reassuring, but this is the use of deterioration.

There are some guidelines for how much charging state to use, but given the characteristics of the smartphone that you carry and use, keeping about 50 % to 80 % to reduce deterioration and practical use.It seems that you can keep the usable state.You should remember the upper limit as 80 %.If you use it with a upper limit of about 80 %, the useful life of a lithium -ion battery will increase.

Some personal computers can set the upper and lower limit of charging.For example, a charging maximum can be set as up to 80 % of the battery, and when the battery starts charging 50 %.If the charging condition is not satisfied, if it is connected to the power supply, it will work only with the power supply and will not be charged to the battery.It is possible to create conditions with the lowest battery deterioration.

The iPhone is often carried more than a PC and does not connect to the power supply.The setting described above is not provided as a default function.However, Apple has improved the battery control of the iPhone, which will slow the charging speed if it is 80 % or more, or to reduce the charging timing around 100 %, taking into account the user's life pattern.ing.For this reason, it is basically considered that the deterioration of the battery is suppressed even if it is connected to the power supply.

However, considering the characteristics of the lithium -ion battery, I think it would be nice to remember that the upper limit was 80%if possible, and to finish charging after 80%.
