Several misunderstandings of mobile phone battery charging

Charging habits don't work for battery life?

Myth: The battery has a fixed life, so it can't be increased or decreased no matter how it is used.
Truth: The life of each mobile phone battery is indeed constant, determined by the number of charging cycles, typically 400-600 times. However, the user's usage habits will also have a greater impact on the battery. Poor use habits, such as overcharging, over-discharge, high-temperature placement, etc., can cause irreversible damage to the battery, making the battery life-threatening, and sometimes there may be safety risks. In addition, by turning off the idle program, you can save power, use every drop of electricity on the blade, and do more meaningful things in a limited amount of power.
Recommendation: Develop good habits, don't wait until there is no electricity to recharge, and don't continue to overcharge for a long time.

The new battery needs to be filled for 12 hours before 3 times?

Myth: I bought a new mobile phone, and many sales clerk will tell you that the first 3 charges should be filled for 12 hours to maintain the ** power.
Truth: This is the "death" of nickel batteries. At present, almost all mobile phones use lithium-ion batteries. There is no memory effect, and it is not necessary to charge for 12 hours.
In addition, excessive charging and discharging of lithium-ion batteries can cause permanent damage to the positive and negative terminals of the battery. Excessive charging causes excessive lithium ions to be embedded in the negative carbon structure, which causes some of the lithium ions to be released again, shortening the battery life, and also has safety hazards.
Recommendation: Do not overcharge or over discharge

When the battery is full, you can unplug the power immediately.

Myth: The phone prompts that the battery is full, you can unplug the power.
Truth: After the "fast charging" phase is completed, in fact, the charging has just completed about 80%, and the battery has a large charging space; in fact, the lithium-ion battery has two processes of "continuous charging" and "turbulent charging". Use third-party battery management software to monitor the state of charge of the battery, allowing it to play a bigger role at critical times.
Suggestion: It is not wise to unplug the charger when the battery display is "100%".

Battery management software is useless for battery life?

Myth: The software cannot change the chemical properties of lithium ions, so it cannot extend the life.
Truth: In fact, in the real world, poor charging power will accelerate battery life, such as users often overcharge, or deplete the battery every time. Under such harsh conditions, the battery is more frequently charged and discharged, and the life decay is faster than under scientific charging conditions. Assuming a battery design life is 500 cycles of recycling, the scientific charge and discharge method can make 500 cycles later. Battery care software can help people use science more.
Recommendation: Users can help users develop good charging habits with power management graphical interface, ringtone prompts, etc., thus extending battery life.

Mobile phone battery is not harmful for one night?

Myth: Many friends use up the electricity during the day and get used to charging at night. They think that even if they are full of electricity, they don't matter.
Truth: This is harmful to the battery! In order to prevent the user from overcharging and causing accidents, the mobile phone battery adopts the design of the overcharge protection circuit, that is, the charging process is automatically terminated after the charging is completed. However, the battery will start the self-discharge process at the same time, causing the power to drop; after the power drops to a certain extent, the charging is started again, and the discharge-charge cycle is continuously performed. However, if it is in a high pressure state for a long time, it will have a negative effect on the battery and cause crystal precipitation, which not only shortens the battery life, but also has potential safety hazards.
Recommendation: Avoid overcharging. It can be used as needed, and it can be filled.

Use no damage to the battery while charging?

Misunderstanding: When many people encounter a phone with no power, because they are afraid of answering the phone, they often make the phone charge on the phone. At the same time, they can make calls, send text messages, brush microblogs, play games, and so on.
The truth: the use of mobile phones while charging and other behaviors can cause damage to mobile phones, people and batteries. Because the voltage of the mobile phone battery when charging is higher than standby, if the call is made at the same time, the voltage at the moment of talking or connecting to the network will be many times higher than usual, which will cause the mobile phone to malfunction; secondly, the mobile phone when charging The radiation is also higher than usual.
Recommendation: Use your phone as little as possible when charging.

Computer USB data cable charging

Myth: The USB output current of the computer is different from the original charger. The USB data cable charging method is harmful to the mobile phone.
The truth: the general original charger, the nominal output voltage DC +5V, the output current 1A; and the general PC USB port standard output voltage is also 5V, the output current is 500mA, according to these data, as long as the computer is well grounded, the USB interface has no quality problems It is completely feasible to charge with the USB data cable, but the theoretical charging time is one time longer than the charger charging, which is a "slow charging".
Recommendation: USB data cable charging is no problem, but don't go to extremes. In addition, you should avoid USB charging all day, avoid phone calls, play games, etc.

A battery is only enough for Android one day?

Myth: I have to go home to charge at night, and one battery can only support one day.
Truth: The answer is of course No! When the power consumption exceeds 40%, the power saving can be realized by automatically turning off the Wifi, 3G, turning down the screen brightness, turning off the positioning, automatically synchronizing, etc., and the power can be extended by 20%.
Recommendation: Android phones are actually more power-hungry. On the one hand, they are caused by the battery used in hardware design. On the other hand, they have a lot to do with the user's usage habits. For example, the openness of Android system will make many applications stay for a long time. The background creates meaningless power consumption, and some devices have no meaning to turn on power consumption for a long time.
