Analysis of Misunderstandings about Charging Mobile Phone

What are the problems of mobile phone battery charging? The battery is a key component of mobile devices, and our mobile phones, tablets and laptops are inseparable from batteries. Of course, electronic skills are developing rapidly, but battery skills are lagging behind. More unfortunately, many users are still using and protecting battery failures. A lot of the discussion about battery usage and protection stems from the past battery skills, if applied to a new battery, these skills may be damaged. Common misconceptions: Fault concept 1: Before use, you must stop discharging and then stop charging. Repeat three times to activate the battery, otherwise the battery will be permanently damaged. Assuming you have nothing to do in your spare time, you can do it, but you don't have to. Since it is not to be activated the first time it is used, the electrode passivation can gradually disappear without activation, as long as it is used occasionally. Fault concept 2: Do not use the mobile phone when charging, it is harmful to the battery and will cause a lot of radiation damage to the human body. Whether using the mobile phone while charging is harmful to the battery depends on the specific circumstances, but one thing is certain, that is, using the mobile phone while charging will not cause more radiation than usual. Fault concept 3: Lithium batteries can only be charged and discharged XXX times in the life cycle, so try to use active shutdown every time you use them, and charge them to full charge every time. It is correct that a lithium battery can only be charged and discharged XXX times in a lifetime, but the following is wrong. Every time is good, for example, from 20% charging to 30% stopping charging, this is only 1/10 times, and from 80% discharging to 60% discharging, this is only 1/5 times. Fault concept 4: The first three charging must reach 12 hours, otherwise it will affect the battery function. Assuming that the battery is activated, only the mobile phone prompts to be fully charged once to meet the demand. The general mobile phone will prompt to be fully charged in 5 hours. If the charger continues to be completed, the overcharge discharge protection circuit will cut off the charging current of the mobile phone, and the battery will not work. The function of dialing immediately after full charge is the same except for the charging cable. The first three models that require 12 hours of charging are nickel-metal hydride rechargeable batteries. As a result, many manufacturers habitually and ignorantly write on the instructions for lithium batteries. It is really scary to have no culture! Dell, Lenovo The world’s largest manufacturers, such as Asus, Asus, and Apple, will certainly not display 12 hours on their products. Regarding lithium batteries, this is a common and part of the principle of operation. Some manufacturers cannot consume 12 hours of demand, and some manufacturers do not. It should be pointed out that the assumption is that the basic charge is used, because most basic charges cannot reach the highest official line current charge. The charging time may exceed 6 hours, but only for full charge, the seat charge will be active power, and the charges are the same. . Fault idea 5: It is best to immediately remove the charging cable when fully charged to prevent overcharging. Overcharge and overdischarge, the protection circuit is not vegetarian, right?!!!!! Assuming an overcharge attack occurs, most overcharge and overdischarge protection circuits will be damaged, but with the technology of today’s electronic products and pressure-bearing Ability, this probability is too low, don't worry. Fault concept 6: Once the mobile phone prompts the user to charge, it must be charged immediately or shut down immediately to prevent over-discharge. This circuit will be forced to shut down when necessary (that is, before over-discharge) without damaging the battery. The mobile phone reminder is to let the user know in advance, so that they can deal with it or prepare mentally in advance. Need attention, assuming that the mobile phone has been actively shut down for the purpose of making a phone call and forced startup, because it may constitute an overput, because of the protection, booting is not completed before most of the charging protection circuit is forced to shut down.
