Wireless charging has a negative effect?Smartphone battery life life
The "TECH 911" corner that answers the troubles of technology received from everyone.
The writer who had a cold I got last week wrote this article while fighting drowsiness under the influence of a lot of cold medicine.Move to today's question before falling on the keyboard.
This is a question from the reader Vignesh.
There are many urban legends in the charging area
Hello Vignesh!First of all, this corner is still going on.If there is nothing, a new article will be published every Friday, so please send more and more tech problems.
We will give you the best advice in any topic, whether you have trouble or choose a device.
If you feel like you want to cry because your precious equipment is broken, please tell me your heart.
By the way, it is the wireless charging of the main subject, but in fact, I am not very familiar with the electronics of smartphones.
In particular, there are countless urban legends, which are effective, safe and long -lasting for charging.
I don't want to be a evangelist in Ese Science, so I would like to clarify the quotes as much as possible and introduce my opinions.
Personally, I would like to think that there is no effect on smartphones after repeating and holding it on a wireless charger.
Wireless charging is a method of creating an electromagnetic field with a coil and generating current to the receiver coil to charge the battery.
In other words, even though the wired charging and technology are different, the results of the battery are the same.
Therefore, if you are not resistant to inserting a wired charging cable many times, you do not need to worry about using a wireless charger like a trampoline.
Not so sacrifice
However, you will have to discuss a more complex smartphone charging cycle.There seems to be various opinions around that.
First of all, according to Matt Reynolds's article, left on a wireless charger is more burdensome on the battery than leaving it with less charging.
Nevertheless, according to an article written by Kent Griffith, a researcher at Cambridge University, smartphone battery makers are restricting the battery even if they continue charging.
It is not a good thing to keep charging smartphones, but it does not harm devices.In other words, it doesn't matter if you do it at your own risk, and there is no sacrifice.
Is it good to charge moderately?
According to Lucas Mearian's article in ComputerWorld, there are still many discussions on smartphone charging, especially wireless charging.
In the article, a certain expert states that keeping charging from 45 to 55%is the way to make the battery life last most long, but I can't help but seem humorous.
Why, then, usually, you don't have a battery for a day.
There are other technologies journalists that have broken the iPhone by wireless charging.The claim is that the charging cycle has been used faster than wired.
On the other hand, Menno Treffers, chairman of Wireless Power Construction, says:
In other words, it seems that you should not charge too much or use too much.
What is more important than the number of charging times ...
The article by Simon Hill of Digtal Trends stated:
The article also mentions the above -mentioned charging cycle issues.
According to this, in order to use a limited charging cycle effectively, be careful of apps that are moving in the background of the device.It seems that the effect is greater than the number of wireless charging times.
Also, be careful of the place where the wireless charger is placed.
For example, stop in front of the window.Heat greatly affects the battery life of the smartphone.Wireless charging alone will give you a heat, but avoid situations where the sun will hit.
Points to maintain the life of the battery
So, if you summarize the information so far, it will be like this.
- スマホのバッテリーにとって、充電残量50%から80%の間を保つのがベストである。
- もっと高い状態を維持してもいいが、寿命に影響する可能性がある。もっと低い状態まで使ってもいいが、バッテリーの充電サイクルを多く消費してしまう。
- スマホをワイヤレス充電器に置きっぱなしにしても、バッテリーを壊すことはない。寿命には多少の影響があるかもしれないが、もっと悪いことはほかにもある。
- 過熱状態の充電器（および過熱状態のデバイス）はバッテリー寿命に悪影響を及ぼす可能性があるので、Amazonなどに出ている怪しい模造品ではなく、評判のいい充電器を使うこと。
- デスクだろうと長距離ドライブだろうと、日の当たる場所でスマホを充電しない。
- 不要なアプリは削除する。意味もなくバックグラウンドでアプリを走らせない。
The following is a personal experience, but I have used wireless chargers on the past two iPhones.
While sleeping (6 to 8 hours), it is left on a wireless charger, but there has never been a problem.
Also, Pixel 3 XL remains on the wireless charger almost all day, but there is no tragic battery problem at the moment.
I bought an iPhone X second -hand, but the previous owner seemed to be charging only with wire.
The battery was weaker than the new one, but I think it is because of how to use it rather than a charging method.
Since then, I have been charging wirelessly, but I have never worsened at once.I can't deny some deterioration, but it's not a sudden change, but it's gradually deteriorating.
And the reason is that it is not because it is placed on a wireless charger every night, but also usage.
I want to read it together
