When charging, plug in the phone or charger first? These wrong charging methods can cause the phone to break down quickly!

For many people in modern society, the amount of battery left on their mobile phones is a 'life threatening' issue.The strong demand for mobile phone charging has also given rise to many gimmicks on the market: wireless charging, double speed charging, and high-energy power banks that can be used continuously for a week

For many people in modern society, the amount of battery left on their mobile phones is a 'life threatening' issue.

The strong demand for mobile phone charging has also given rise to many gimmicks on the market: wireless charging, double speed charging, and high-energy power banks that can be used continuously for a week.

Chaohua is gradually becoming charming, but what is the correct posture for charging a mobile phone?

01

Must the phone be fully charged?

There are always rumors about charging: when the phone runs out of battery, it needs to be fully charged every time, which is beneficial for battery maintenance. Charging at any time can affect the battery life.

In fact, these theories are quite outdated.

Simply put, when the battery is not fully discharged or fully charged multiple times, the battery capacity will "remember" the amount of electricity during charging and power-off, treating it as the maximum and minimum values of electricity, resulting in a decrease in battery capacity.

Lithium ion batteries.

The precautions for lithium-ion batteries are exactly the opposite of those for cadmium nickel batteries: do not charge them again when they are out of charge, nor overcharge them, as there is no need to charge and discharge them deeply every time.

The life of the lithium-ion battery is related to the Charge cycle. Every time 100% of the power is used, a cycle is achieved. The more cycles, the more obvious the decline in battery life.

A study on 11 types of lithium ions showed that after 250 cycles, the battery capacity significantly decreased.

After achieving 300-500 cycles, the battery capacity will decrease to 80% of its original capacity.

What principle is this?

Data shows that when deep charging and discharging lithium-ion batteries, the material structure of the positive and negative electrodes will be destroyed. And lithium-ion batteries mainly rely on the movement of lithium ions between the positive and negative electrodes to work. Once the space to accommodate their activities decreases, the battery capacity will correspondingly decrease.

So,Compared to "fully charging", "multiple undercharging" is a more suitable charging habit for mobile phones nowadays.

In addition to the amount of electricity before and after charging, another issue that is easily overlooked by people also affects the battery's lifespan.
