Nowadays, mobile phones have become an essential communication tool for us. However, in order to make your phone last longer and safer, you must know the correct charging method for your phone, as well as the misconceptions about charging your phone battery.

Mobile phones are essential items for modern people. Nowadays, almost everyone has a mobile phone, and charging it has become a daily necessity for us. But do you know what are the misconceptions about charging mobile phone batteries? What is the correct charging method for mobile phones? Let's take a closer look below.

Misconceptions about charging mobile phone batteries

Misconception 1 of mobile phone charging: How many times do new batteries need to be fully charged and discharged to activate

Lu Jianguo, Director of the Comprehensive Inspection Department of the National Household Appliance Quality Supervision and Inspection Center of the China Academy of Home Appliances, told reporters that different battery products require different methods of charging, and must be used according to the product instructions. Early nickel cadmium batteries and nickel hydrogen batteries required similar "activation". These batteries produce a 'memory effect', charging them in an incompletely discharged state can easily lead to overcharging, and over time, users may feel like their battery is running out quickly. However, most of the batteries used in mobile phones and laptops today are lithium-ion batteries. Its initialization process has been completed during manufacturing, so it does not need to be activated when it is first used.

Misconception 2 of Mobile Phone Charging: Reducing Charging Times Can Extend Battery Life

The lifespan of a typical lithium-ion battery can reach several hundred charge and discharge cycles, where the charge and discharge cycle refers to the process of using up the battery before recharging, rather than simply plugging in the charger and unplugging it once. Lithium batteries do not have a memory effect and can be charged at any time. Deliberately using up the battery and then recharging it to reduce the number of charges does not extend its lifespan, but instead has a negative impact on its lifespan. In addition, if the phone uses automatic shutdown, the lithium battery may experience low internal voltage due to excessive discharge, which may result in the inability to turn on and charge. Therefore, when charging lithium batteries, it is important to eat small meals frequently, and frequent shallow charging and discharging can help extend their lifespan.

Misconception 3 of mobile phone charging: Overcharging can cause battery explosion

Lithium batteries generally have safety protection circuits and various safety devices to ensure that the battery's circuit is automatically cut off in the event of overcharging, discharging, or short circuits; Excessive internal pressure in the battery can also trigger the exhaust system to reduce pressure; If the battery temperature is too high, it will trigger the hot melt protection device, thereby stopping the electrochemical reaction of the battery. Therefore, unless there is a quality issue, the battery will not explode due to prolonged charging. However, not unplugging the power after being fully charged will keep the battery fully charged. Although it will not explode, it will accelerate the rate of battery capacity loss.

Additionally, there are rumors that answering a phone while charging can cause an explosion. Experts say that this statement is untenable. If such a danger really exists, the product will set a program to not connect to the phone during charging. However, from a health perspective, wires can limit the user's range of motion, and making or receiving phone calls while charging may keep the user fixed in one place for a long time, causing excessive muscle tension. Therefore, it is recommended to unplug the power before making calls. When charging, do not cover anything on the battery and do not place it on the bed to avoid a fire.

Common knowledge of the correct charging method for mobile phones

Before the battery leaves the factory, the manufacturer has activated it and pre charged it

Therefore, all batteries have residual power. Some friends say that the battery is charged according to the adjustment period, but the standby time is still seriously insufficient. Assuming that the battery is indeed a genuine battery, in this case, the adjustment period should be extended and fully charged and discharged 3-5 times.

If the newly purchased mobile phone battery is lithium-ion

So the first 3-5 charges are generally referred to as the adjustment period, which should be charged for 12 hours to ensure full activation of lithium ion activity. Lithium ion batteries do not have a memory effect, but they have strong flexibility and should be fully activated to ensure optimal performance for future use.

3. Some automated intelligent fast chargers only indicate that they are fully charged at 90% when the indicator light changes

After charging to 90%, the charger will automatically change to a slow charging mode to fully charge the phone. Therefore, it is best to fully charge the battery before use, otherwise it will shorten the lifespan of the phone.

4. Before charging, lithium batteries do not need to be discharged specifically. Improper discharge can actually damage the battery

When charging, try to use slow charging to reduce fast charging methods; Do not exceed 24 hours. After three to five complete charge and discharge cycles, the internal chemicals of the battery will be fully activated to achieve optimal performance.

5. Please use original or reputable brand chargers

Lithium batteries should be charged with a dedicated charger and follow the instructions, otherwise it may damage the battery and even cause danger.

Many users often keep their phones on while charging, which can easily damage the lifespan of their phones

Because during the charging process, the circuit board of the mobile phone will generate heat, and if there is an external phone, it may produce instantaneous backflow current, causing damage to the internal components of the phone.

7. The lifespan of a battery is determined by the number of repeated charging and discharging cycles, so it is advisable to avoid charging when the battery has excess power

This charging situation will shorten the lifespan of the battery. When turning off a mobile phone, it should not exceed 7 days. Firstly, the phone's battery should be completely discharged before use.

8. Mobile phone batteries all have self discharge

When not in use, nickel hydrogen batteries will discharge at around 1% of their remaining capacity per day, while lithium batteries will discharge at 0.2% to 0.3% per day. When charging the battery, try to use a dedicated socket instead of sharing the charger with household appliances such as televisions.

Although the phone is within the network coverage area, it can no longer receive or make calls when the phone is turned off and charged

At this point, you can use the unused transfer function of your phone to transfer it to a nearby landline phone to prevent call loss. This method is also applicable when the phone is not within the network coverage area or the signal is weak and temporarily unable to connect.

10. Do not expose the battery to high temperatures or extreme cold

During the dog days of summer, mobile phones should not be left in cars and exposed to the scorching sun; Or take it to an air-conditioned room and place it in a place where the air is blowing directly. When charging, it is normal for the battery to be a little hot, but it should not be subjected to the torment of high temperatures. To avoid this situation, it is best to charge at room temperature and do not cover anything on the phone.

Before charging nickel cadmium (NiCd) batteries, it is necessary to ensure that the battery is completely discharged

After recharging, it is necessary to ensure that the battery is fully charged.

If the phone battery has been left unused for too long, it is best to apply to the phone repair department for a battery repair

You can also use a DC constant voltage regulator to adjust the voltage to 5-6V and the current to 500-600mA, and connect the battery in reverse. Note that it can be released with just one touch, and can be repeated up to three times. After this process, use the original charger for the "adjustment period" charging.

13. Charging time is not always better

After fully charging a battery without a protective circuit, it should be stopped, otherwise the battery's performance may be affected by heating or overheating.

14. Lithium ion batteries must use dedicated chargers

Otherwise, it may not reach saturation and affect its performance. After charging, avoid leaving the charger for more than 12 hours. When not in use for a long time, separate the battery from the phone.

The above is an introduction to the correct mobile phone charging method. If your charging method is still incorrect, be sure to correct it.

Conclusion: Friends, through the analysis of the above article, can you understand the misconceptions of charging mobile phones and what is the safest way to use them? How can you make your phone last longer? I hope this article is helpful to everyone.
