Is it possible to charge the phone quickly? Technology to help you explain

According to the New York Times website, users are likely to plug in the power to charge the phone before going to bed at night, and the phone is fully charged when the next morning wakes up. But is this really ok?

This depends on the situation.

Is it possible to charge the phone quickly? Technology to help you explain

The reason is this, users usually use a mobile phone for less than 2 years. Experts say that in most cases, people will not notice how much damage the cell phone battery is before considering buying new phones. Therefore, there is no problem with the user charging overnight.

However, frequent charging is detrimental to the lithium ion battery in the mobile phone. Edo Campos, a phone charger manufacturer Anker spokesperson, said the reason is not that the battery is overcharged. "In fact, smartphones are smart enough to know when they should stop charging."

Android phones and iPhones are equipped with related chips that protect them from "absorbing" excess power when fully charged. Therefore, in theory, using official chargers, or trusted third-party chargers, the damage caused by overnight charging of the phone is negligible.

The New York Times said, however, that charging itself is harmful to the battery for the following reasons. Most mobile phones utilize fast charging technology to enable mobile phones to receive power more quickly. Hatem Zeine, founder, chief scientist and chief technology officer of wireless charging technology company Ossia, said that fast charging technology allows the phone to adjust the speed of receiving power based on the charging capacity of the charger.

Fast charging technology allows energy to quickly enter the battery, speeding up the transfer of lithium ions from one pole to the other, thereby increasing the charging speed of the battery.

However, this process can lead to faster loss of lithium ion (and lithium polymer) batteries. Zain said, "If you always charge quickly, battery life will be affected."

How to solve this problem?

Zain suggested that if you want to make the life of a lithium-ion battery exceed that of a mobile phone or tablet, users can use the charger for low-power devices to charge the device, but he can't guarantee that this trick is effective.

“For example, if you charge the iPad Pro with an iPhone charger, the charging speed will be very slow, which helps to extend battery life because of the slow charging speed,” said Zain.

According to The New York Times, Campos suggested that users who wish to extend battery life should ensure that the phone does not overheat, as high temperatures can further stimulate lithium ions in the battery and accelerate battery drain. Information on the Apple website shows that temperatures above 95 degrees Fahrenheit (35 degrees Celsius) can have a permanent effect on battery life.

Zain and Campos said that in view of the "tired" pursuit of new mobile phones, charging mobile phones overnight is not a big problem. This actually has little impact on consumers. A 2015 Gallup survey showed that 44% of smartphone users replace a mobile phone every two years, and mobile phone batteries usually begin to show capacity loss after two years. sign.
