Is it a superstition that "continuing to charge a smartphone will lead to battery aging"?

Life hacker [Japanese version] reprinted the article published on September 1, 2018

I hate people who do wrong things because of "always doing this".

For example, people who force movies, games, music, etc., to run out of batteries on their smartphones. These people think that the battery must be used up before recharging.

Charge the battery when you like it.

I have dealt with this problem before, but I will cite evidence again to illustrate it. After all, there are still a lot of people (including my cohabitants) who continue to make this mistake. Don't do such a ridiculous thing again.

Smartphones just need to be recharged at the time they like. The lithium-ion battery of a smartphone doesn't care if the battery is 10% or 80%. No matter when charging, the battery life will not be shortened.

Can you believe it? There are people like that, too. However, this is Apple's official view.

Apple's lithium-ion battery can be recharged at any time. You don't need to use up all the power before recharging. Apple's lithium-ion battery can be recharged repeatedly.

When you use up the power equivalent to 100% of the battery capacity (after discharge), you will complete a charging cycle, but you do not necessarily need to use up every charge.

For example, suppose 75% of the battery capacity is consumed in one day and fully charged at night. The consumption of 25% the next day, that is, a total consumption of 100%, means that the charging cycle is completed in two days.

It is true that lithium-ion batteries have less rechargeable capacity when they are recharged repeatedly.

Anyone who uses iPhone will bite into the fact that Apple launches a new smartphone every year.

But, as Apple describes it, "lithium-ion batteries lose very little capacity each time they complete a charging cycle."

So, if you care about battery life and deliberately use the battery, it will have the opposite effect.

Stop using the battery reluctantly and increase the charging cycle unnecessarily. Just charge it normally.

About charging smartphones at night

What about other myths about batteries? There seem to be different opinions on when smartphones should be recharged, when they should not be recharged, and what percentage of the battery level should be maintained.

According to the American Chemical Society video below, if you don't use a smartphone battery for a long time (such as a few months), you should basically keep the battery at about 50%.

So, you must have asked once, what about "Triker charging"?

If you connect the smartphone to the charger at night, the charge drops to 99% each time, and there will be multiple "charging" problems.

The question of multiple sources of information does not seem to be just a myth, but there are all kinds of different opinions on what to do.

What's the answer?

I'm not too worried about this problem.

Please charge me normally.

Get up in the toilet in the middle of the night and unplug the cable when you think of it.

And then recharge you a little before you go to work. When you go to lunch or attend the morning meeting, please unplug the cable.

You will get some benefits by slightly raising your awareness of charging than usual.

Even if the battery itself deteriorates over time, your efforts will pay off. All that's left is to accept what lasts forever and nothing.
