Is it necessary to charge the lithium battery for more than 12 hours the first three times?

My answer is also yes!!

Based on my many years of mobile phone sales experience, when selling phones, we will remind customers that it is best to charge them for 12 hours for the first time. three times, they go backwards, but Do not charge more than 14 hours {If you charge it for a long time (referring to usual charging), the battery will be charged to a small bulge, which means it is almost at the end of its lifespan. lifespan

When charging normally It is best to charge it for about 1-2 hours after it is fully charged (the time required for each brand of mobile phone to be fully charged is different, see how long it says in your manual)!!on the loading method and then we leave them next. charge it three times before seeing the effect. Most customers can solve the problem).

Indeed, if the battery is not fully charged the first three times, the capacity and power of the battery will decrease. be determined in the future! Anyway, whenever our manufacturer has a new model in the market, I will give us a demo machine. They all charge like that My colleagues/colleagues who work with other cell phone brands/everyone who does!! repairs/sells cell phones/agents or even used cell phone dealers, anyway, anyone who has anything to do with cell phones knows how to charge like that!! *Some customers have problems because the first three charges were not done correctly, what people often say is that the lithium ions are not completefully activated*

There are many. Let me talk about battery standby time First, check whether the cell phone has such power-saving “function” or “technology”. For example: Philip, their cell phone has a long standby time, not all batteries used have large mAh capacity. Not all models have such a long standby time, that is, which ones have this "technology" that can allow them to have a longer standby time.

Second , it depends on the capacity of the mobile. phone, i.e. how many amp hours/mAh it has.

What a friend said above is partly true! The larger the capacity, the better the utilization. The duration will also increase! time, I didn't tell him "Charging is like adding water to a bottle. It will be full after 2 hours. It won't do any good if you add another 10 hourses!" 90% of current batteries are lithium-ion (others are based on nickel metal hydride, etc.), not water, although it does not have a memory effect like the nickel metal hydride batteries (you must use the electricity before recharging, otherwise it will have "memory" after long-term use Effect: "Recharge it and you will find that the standby time is not as good as the standby time when you just bought it.) The characteristics of lithium batteries are different from those of nickel-metal hydride batteries, and they are not comparable to the "water" ones my friend compared.

Lithium batteries are exactly the opposite in daily use (except the first three times). It's *better* not to use them every time, even if you can't turn on your cell phone. This will have a negative impact on the life of the lithium battery. This also hast some impact. Generally speaking, if lithium batteries are not used for a long time, it is best to fully charge them before putting them in. If some brands of lithium batteries are not used for a long time, you will find that they will be used. It will not work well if you charge it in a cell phone. This is also the characteristic of lithium ions in lithium batteries, - lithium ion standby - these batteries should be used by mobile phone maintenance department with 10V~15V regulated power supply. (each maintenance department of the cell phone must (Preparation) Align the + - poles of the battery to "activate". Although most of these batteries are good, they will not be the same as when you first purchased them (Some will also be inactivated)

The third is to look at the first three charging times If the tank.ge is short, the lithium ions cannot be fully activated, and the best use effect will not be achieved.

The fourth depends on how you use it.

The way to use it is whether you use your mobile phone not only to make calls/send text messages/but also to listen to MP3/take photos/videos/check next time/sometimes use infrared /transfer Bluetooth data/Internet browsing/ringtones/news, etc., the standby time of your mobile phone at the end of the day (if calculated on a daily basis) will not be too long~~ Haha

The method of use is so, you If the mobile phone is in a place with low or unstable confidence for a long time or sometimes, the standby time will be greatly reduced.

Look carefully at the brochures promotional offers from all cell phone manufacturers without exception. TWe will add a * sign after the standby/talk time, there will be notes below

*Actual call and standby time varies depending on local network conditions, settings of the SIM card and usage habits. We now use China Mobile's GMS dual-band network (900M\1800M frequency) or China Unicom (900M frequency, except CDMA). They basically have a "transmission tower" every 20 kilometers in radius (base stations, which transmit mobile phone signals). Such "circles" one by one form a cellular-type network coverage, which is why previous mobile phones were also called - cellular mobile phones. - (previous Motorola V998/368C and other boxes can also see, it's not written like that now.) That is, the closer your mobile phone is to the base station, the lower the power consumption of your mobile phone is faible, the more energy we save and the longer the standby time, but not the opposite. Of course, living in There will also be blind spots in the city, such as basements, parking lots, elevators that are not covered by the network, etc. In this case, the standby time will also be shortened!!

You can try it, if you use It is the local "local access card" when you go out to play When it n If there is no network, you will find that your cell phone battery will run out quickly because it is continuously searching for the network.

So it is said to be on standby. Duration is inevitably related to various aspects.

Haha, after saying so much, I hope it can be helpful for your question~~~Finally, lithium batteries have always need to be charged for more than 12 hours the first three times!!

Take a 600 mAh lithium battery as an example. The first time shewas charged from 0 mAh to 400 mAh, it took N milliamps, then it was recharged to 150 mA, then finally used N mA; when the maximum when charged at 50 mA for the last time, a charging cycle of this battery is completed. (400+150+50=600)

How to calculate the charge cycle of a lithium battery

A lithium battery only uses half its power on the first day, then fully charges it. If it is still the same the next day, i.e. if you charge it half and charge it twice in total, this can only be counted as one charging cycle and not two. Therefore, multiple charges may often be required to complete a cycle. Each time a charge cycle is completed, the battery capacity decreases a little. Lithium batteries may need to be replaced once their lifespan has expired.

The lifespan of lithium batteries is generally300 to 500 charge cycles. Assuming that the power provided by a full discharge is 1Q, if the power reduction after each charge cycle is not taken into account, the lithium battery can provide or supplement a total of 300Q to 500Q of power over of its lifespan. From this we know that if you charge 1/2 each time, you can charge it 600-1000 times; if you charge it 1/3 each time, you can charge it 900-1500 times. By analogy, if it is charged randomly, the number of times is uncertain. In short, no matter how you charge it, the total amount of electricity added is 300Q to 500Q, which is constant. Therefore, it can also be understood this way: the lifespan of a lithium battery is related to the total charging capacity of the battery and has nothing to do with the number of charging times. There is little difference in the impact of a deep discharge, a p chargedeep and superficial discharge over the life of lithium batteries. Well, some MP3 manufacturers claim in their propaganda: “A certain model of MP3 uses a powerful lithium battery that can be recharged more than 1,500 times. » This is only to deceive consumers and lead them to ignorance.

In fact, surface discharge and surface charge are more beneficial for lithium batteries. Only when the product power module is calibrated for lithium batteries is it necessary to deeply discharge and charge. Therefore, products powered by lithium batteries do not necessarily have to stick to the process. Everything is done with convenience in mind. You can charge them at any time without worrying about affecting their lifespan.
