How to charge your phone battery ?

What is the best way to charge a mobile phone battery?

In today's era where smartphones are almost universally prevalent, mobile phones are becoming increasingly important in our daily lives - from mobile payments, watching videos, listening to music to navigating our way around. With such frequent use of mobile phones, battery life naturally becomes a concern. As the number of times we charge our phones increases, the battery life becomes shortermainly due to the gradual deterioration of the battery.

The deterioration of the battery is due to the limitations of battery technology and the impact of charging habits on the battery. What is the healthiest way to charge your phone battery? Is charging the battery directly to 100% good for the battery?

Overcharging and over-discharging can affect battery life

The charging and discharging process of a lithium-ion battery actually involves lithium ions constantly moving between the positive and negative electrodes. During the charging process, the lithium ions in the positive electrode pass through the electrolyte and the separator to reach the negative electrode and receive electrons to form lithium atoms, which are embedded in a layered structure of the negative electrode.

When the battery is charged too full, a large number of lithium ions flow into the negative electrode to produce lithium atoms. In this process, the accumulation of lithium atoms can easily cause dendrite growth, which can gradually grow and puncture the separator between the positive and negative electrodes, resulting in a shortened battery life.

Generally speaking, the best state for the battery's charge level is around 80%.

Moreover, excessive discharge of the battery can cause irreversible damage to the battery. During the discharge process, lithium atoms will detach from the layered structure of the negative electrode and lose electrons, flowing to the positive electrode. When a large number of lithium atoms detach from the layered structure, it will cause the structure to collapse. The structure will gradually be damaged and the number of lithium atoms that can be embedded later will decrease, resulting in a smaller battery capacity.

Therefore, both overcharging and over-discharging of lithium-ion batteries can affect battery life, and over-discharging can have a more significant impact on the battery than overcharging. A research paper on the factors affecting the cycle life of lithium-ion batteries found that the battery's cycle life is the longest when the battery's charge level is maintained at around 30%-80%.

Shallow charge/discharge is healthier for batteries

The above content describes the principle of the damage caused by overcharging and over-discharging to the battery. To a certain extent, to extend the battery life, it is natural to avoid excessive charge and discharge, and the best way to charge the battery is to charge and discharge shallowly and keep the battery level between 30%-80%.

Some people may think that this will increase the number of charge and discharge cycles of the battery, thereby shortening the battery life. This is actually a misunderstanding. The true cycle of a battery refers to using up 100% of the battery's capacity.

For example, if a battery with 100% charge is used once until it reaches 0%, and then it is fully charged again to 100%, then this battery has completed one cycle. If you use a battery with 80% charge until it reaches 30%, then you have used 50% of the battery capacity. If you charge it to 80% again and use it until it reaches 30%, you will have used another 50% of the capacity. After these two processes, the battery has completed one cycle. Therefore, the battery's usage cycle is not related to the number of times it is charged, but rather to how much capacity is used up.

Therefore, shallow charging and discharging can effectively avoid damage caused by overcharging and over-discharging to mobile phones, making it a healthier way to charge.

The correct charging method can not only extend the battery life but also improve the overall performance of the phone. We will now introduce how to charge new phones to protect the battery from different angles, and provide various methods and suggestions to maximize battery protection.

To protect the battery life of a new phone, pay attention to the following points:

1. Initial charging: Modern mobile phones do not require a long initial charge. Usually, it is enough to charge it to full.

2. Daily charging: Avoid charging the battery only when it is less than 20%, and keep the battery level between 20%-80%. Unplug the charger promptly after the battery is fully charged, and do not charge it overnight. Use original or certified chargers and avoid high-temperature environments.

3. Charging habits: It is not necessary to charge the battery to 100% every time. Partial charging is more beneficial. Regularly calibrate the battery and occasionally discharge it completely to 0% and then fully charge it. Avoid frequent use of fast charging and use regular charging mode as much as possible.

I. Charging advice when first used

When charging a new phone battery for the first time, it does not require a particularly long time. Usually, charging it according to the manufacturer's recommendations is enough. Generally, it takes 2-3 hours to fully charge, and there is no need to overcharge it for a long time.

II. Daily charging methods

1. Avoid over-discharging the battery

Lithium-ion batteries are very sensitive to over-discharging, and frequently discharging the battery to 0% may cause damage to the battery. It is recommended to charge the battery when the battery level is less than 20%, and keep the battery healthy by maintaining a level of 20%-80%.

2. Avoid overcharging

Although modern mobile phones usually have overcharge protection, leaving the charger plugged in for a long time may still have an adverse effect on the battery. It is best to unplug the charger promptly after the battery is fully charged, especially avoiding overnight charging.

3. Use original chargers

Use original or certified chargers and data cables for charging to ensure stability and safety. Poor-quality chargers may cause damage to the battery or even pose safety hazards.

4. Avoid high-temperature environments

Avoid high-temperature environments during charging, because high temperatures accelerate the aging process of the battery. It is recommended to charge the battery in a well-ventilated environment and avoid placing the phone in a place that receives direct sunlight or a high-temperature environment.

III. Charging habits and precautions

1. Partial charging instead of full charging

Lithium-ion batteries do not need to be charged to 100% every time, and partial charging is more beneficial to battery health. For example, you can stop charging when the battery level reaches 80%-90%. This can reduce the pressure on the battery.

2. Regular battery calibration

Although it is not necessary to calibrate the battery frequently, doing so occasionally can help maintain the accuracy of the battery. The method is to discharge the battery completely to 0% and then fully charge it to 100%. This should be done every few months.

3. Avoid frequent use of fast charging

Although fast charging technology is convenient, frequent use may affect the battery life. It is recommended to use the regular charging mode as much as possible in daily use and only use fast charging when needed.

4. Use battery management tools

Many mobile phones have built-in battery management tools that can help monitor battery usage and provide charging optimization suggestions. Make full use of these tools to better maintain battery health.

IV. Charging in special situations

1. Charging when the phone is not used for a long time

If the phone needs to be unused for a long time, it is recommended to keep the battery level at around 50% and partially charge it every few months. Avoid storing the battery completely discharged, as this may cause over-discharge damage to the battery.

2. Charging in flight mode

Charging the phone in flight mode means that the phone will not receive signals and notifications, reducing the workload of the battery and improving charging efficiency and effectiveness.

V. Precautions for wireless charging
