Common misconceptions about mobile phone battery charging

Misconception 1: First use must be fully discharged, and then fully charged, repeat three times in order to activate the battery, otherwise the battery will never be useful. If you have nothing to do in your spare time, you can do this, but it is not necessary. Because the activation operation does not have to be done at the first use, as long as the process of continuous use, the electrode passivation can slowly disappear without deliberate activation. Myth 2: Do not use your mobile phone while charging, it is harmful to the battery, and there will be a large amount of radiation that can harm the human body. Whether using a mobile phone while charging is harmful to the battery depends on the situation, but one thing is certain is that using a mobile phone while charging will never cause more radiation than usual. Myth 3: Lithium-ion batteries can only be charged and discharged XXX times during their life cycle, so try to use automatic shutdown every time you use them, and charge them to full charge every time you charge them. It is correct that a lithium-ion battery can only be charged and discharged XXX times during its life cycle, but the latter is wrong. Each of these times refers to a complete one. For example, charging from 20% to 30% stopping charging is only 1/10 times, and discharging from 80% to 60% is only 1/5 times. Myth 4: The first three charging must reach 12 hours, otherwise it will affect the battery performance. If it is to activate the battery, as long as the mobile phone prompts full charge, it is enough. Normal mobile phones will prompt full charge within 5 hours. If you continue to connect the charger after completion, the overcharge and overdischarge protection circuit will cut off the charging current of the phone, and then the battery will be fully charged. In the non-working state, the effect is the same as removing the charging cable immediately after being fully charged. The first three times of charging must reach 12 hours is for Ni-MH rechargeable batteries. As a result, many manufacturers habitually and ignorantly write in the lithium-ion battery user manual. It is terrible to have no culture! International manufacturers, such as Dell, Lenovo, Asus, Apple’s products will never appear in words like 12 hours. And for lithium-ion batteries, this is a common feature and part of the working principle. It is impossible for some manufacturers to produce it in 12 hours, and some manufacturers do not. It should be noted that if the charger is used, since most of the chargers cannot reach the maximum current of the official line charger, the charging time may exceed 6 hours, but as long as it is fully charged, the charger will automatically cut off the power and use the line Charging is the same. Myth 5: It is best to remove the charging cable immediately after it is fully charged to prevent overcharging. Overcharge and overdischarge, the protection circuit is not vegetarian, OK?!! If overcharge occurs, it is mostly because the overcharge and overdischarge protection circuit is damaged, but in terms of current electronic product technology and pressure resistance, this probability is really low. If it doesn't work, don't worry about it. Myth 6: Once the mobile phone starts to prompt 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 reminder of the mobile phone is to let the user know in advance, so as to deal with it or prepare psychologically in advance. It should be noted that if the mobile phone has been automatically turned off, you must not force it on for the purpose of making a call, because it is likely to cause overdischarge, and due to the existence of protection, it will probably be overcharged and overdischarged before the power on is completed. Power off forcibly. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
