How long does it take for iPhone4s to charge for the first time?

For the "activation" of lithium batteries, there are many sayings: the charging time must be more than 12 hours, and it must be repeated three times in order to activate the battery. This statement that "the first three charges should be charged for more than 12 hours" is obviously a continuation of nickel batteries (such as nickel-cadmium and nickel-metal hydride).

So this statement can be said to be misinformation from the beginning. There is a very big difference between the charging and discharging characteristics of lithium batteries and nickel batteries, and it can be very clear that all serious formal technical information emphasizes that overcharging and overdischarging will cause great harm to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours.

In general, the charging method introduced in the manual of the mobile phone is the standard charging method suitable for the mobile phone.

In addition, the mobile phone or charger with lithium battery will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours as a nickel electric charger. That is to say, if the lithium battery is fully charged, it is also white charged when placed on the charger. No one can guarantee that the characteristics of the battery's charge-discharge protection circuit will never change and the quality will be foolproof, so the battery will be on the verge of danger for a long time.

This is another reason against long charging.

Therefore, the iPhone 4S can be fully charged for the first time.

The first charge of 10 hours, in the past, the battery paid attention to three discharges and three charges, but now the technology is advanced, theoretically speaking, the lithium battery has no so-called memory effect, but the first charge is still recommended to charge for a while for the first time! Usually pay attention not to use up the battery completely when you use it, you should charge it when you usually use it to 20%, don't use it up and then flush it, this is not good. And as you go, you can charge and discharge it completely once a month, so that the life of the battery can be extended!

The iPhone does not have the same first charging requirements as other batteries due to the battery material, and the number of charges consumes 100% of the power consumption according to the power consumption.

First of all, it is related to the iPhone 4, the battery has a lifespan, and the actual storage capacity of the battery decreases due to the increase in the use time (except for insufficient charging).

Secondly, it is related to the use of the network, after connecting to the network, it is very different from the power consumption of non-stop use, so it cannot be simply said that it is normal or not.

Therefore, "3G Internet access will reach 20% in 4 hours", which is normal in the case of intermittent use.

This is normal... If you go online, that's what it looks like

I've been using Apple for many years, and as far as I know, there are three things you can learn about:

First of all, we generally have the idea that it is better to charge the battery power of the mobile phone after all the power is discharged, which is basically true, because most of the rechargeable batteries we used in the past are nickel-metal hydride (NIH) batteries, and nickel-metal hydride batteries have the so-called memory effect, if you do not discharge and recharge, it will lead to a rapid reduction in battery life. However, most of today's mobile phones and general IA products use lithium (Li) batteries, and lithium batteries do not have the problem of memory effect. If you still wait until all the electricity is used up before charging, it will make the inside of the lithium battery.

The chemical substance cannot react and its lifespan is reduced. So, you can charge and use it as you go.

Second, the life of the iPhone battery begins to decay after 500 "full" charges. "Completely" means that if you recharge it with 50% of your battery every day, then it will take two days to fully charge 1 time. Then 500 times can be used for 1000 days = 3 years.

Finally, it's about taking care of the battery. Try to recharge once a month, that is, start charging when your battery is below 20% and charge until it is full; Also, try not to pull it out when charging.

I hope the above points will be useful to you.

[iPhone4s correct charging skills].

1. The first flush does not have to be charged for 12 hours, it only needs to be fully charged;

2. In fact, it can be charged at any power, and it has little impact on the battery;

3. It is best to have a complete release and charging process once a week, that is, from the red power to the full charge, it is best to achieve a battery run out once a week, and then fully charge.

4. The function of overshoot protection for the mobile phone, but it is still recommended to unplug the mobile phone after it is fully charged, and it is not recommended to charge it for a long time.

5. When charging to 100%, unplugging the charger is the best moment, charging 100% and charging for another hour, the battery power when unplugging the charger is not just 100% full, that is to say, after being fully charged, iphone4s has entered the overshoot protection, has stopped charging, and the next time is only the battery consumption process, so there is no need to charge more.

6. When the power of the mobile phone is too low, you should stop playing with the mobile phone or talking in time and charge it as soon as possible to maintain the life of the battery.

Use 20% of the power to charge for 10 hours, and then you can charge it at any time, mine is 4s 32g, I asked the Apple clerk!!

If it is less than 20%, there will be a prompt to charge, and it will take about 2 hours to wait after it is fully charged.

1. The iPhone4S battery uses a lithium polymer battery, and there is no memory effect, so it definitely does not need to be charged and discharged thoroughly every time (that is, you can charge it whenever you want).

2. The power of the iPhone4S battery will be reduced a little after each charge-discharge cycle, and it will be reduced to 80% after about 400 charge-discharge cycles. The so-called one-charge and discharge cycle refers to a complete charge and discharge, that is to say, if you use 20% of the electricity to be fully charged, it must be repeated 5 times to count a charge-discharge cycle.

3. Since there is a chip in the iphone4s battery to calculate the power, in order to calibrate, a complete redischarge should be done once a month (that is, it is completely fully charged and used until it runs out).

5. The charging process of the iPhone4S battery is that the first 80% can be completed by fast charging for 2 hours, and the last 20% can be charged continuously for 2 hours. This is normal and does not require anything in particular. Look

You can rush as much as you want, this iPhone does not have the same regulations as other mobile phones.

Now it is all lithium batteries, and the manufacturer has already activated it when it produces the mobile phone, so it is purely the previous reason to rush for 10 and 12 hours to activate this.

Generally, it can be full in 4-5 hours, and it is recommended to get a Kingsoft battery doctor in iTunes, which is very convenient and easy to use.

The next Kingsoft battery doctor, it has a hint, 4s to charge below 20% of the power, this at least once a month, three charging methods, and then the specific operation it will prompt, I also just bought it today, the salesman taught, not to advertise, you can refer to it...
