How long does it take to charge the first three charges of iPhone4s?

Just fill it up. It does not need to be charged for 12 hours.

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.

The first three charges of the iPhone can be fully charged, and it does not take long to be fully charged.

Previously, there was a saying that the mobile phone battery needs to be fully charged for 12 hours for the first three times, this is for the original nickel-cadmium battery, this kind of battery has a memory effect, and it needs to be activated in the first three times to get a better battery life.

The lithium battery used now does not need to do this, the mobile phone can be fully charged, even if you do not unplug the charger, the mobile phone battery will automatically disconnect the power supply and stop charging after it is fully charged.

Therefore, the current mobile phone, the first charge, only needs to be fully charged to 100% and then disconnect the power supply.

1.Normal charging is sufficient, and now lithium batteries are used, which do not need to be activated and have no memory.

2.You can charge it normally every time, and disconnect the charging connection when the phone prompts it to be full.

3.Don't wait until the battery is dry to charge, you should charge when the device says the battery is low, over-discharge will affect your battery life.

4.Try to avoid charging before going to bed, because the charging time before going to bed is longer, and the voltage is unstable at night, and the night voltage in many places is relatively high and fluctuates greatly, which has a greater impact on the battery.

5.The activation of the lithium battery does not require a special method, and the lithium battery will be activated naturally during the normal use of the mobile phone.

6.Avoid short circuit of the battery, and high-current discharge is not good for battery life.

7.Lithium batteries should be charged to more than 60% for a long time, stored separately in a cool and dry place, and replenished every few months.

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...

It is best not to charge for more than 12 hours for the first three times.

The first three continuous 12-hour charging is for nickel-metal hydride or nickel-cadmium batteries, and the charging and discharging characteristics of lithium batteries and nickel batteries are very different.

The mobile phone or charger of 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 in the nickel battery charger, that is, if your lithium battery is fully charged, it is also white charging on the charger.

Precautions for phone charging:

1.The mobile phone charging equipment is best original, the original charger is most suitable for that mobile phone, the power of the charger is large and small, the power is small, the charging is slow, the power is large, the charging is fast, but it will not be long before the battery will be replaced.

2.In the case of low temperatures, the battery's built-in protection makes it impossible to charge or very slow, and when the temperature is too high, the battery is unstable, which is very likely to happen**. Most phones are suitable for charging at temperatures between 10 and 35.

3.Don't play while charging, the mobile phone is charging the Internet or talking, the radiation at this time is very large, because the current itself will produce a strong magnetic field when charging, coupled with the influence of infinite electromagnetic wave signals, so the radiation can be imagined. When charging, try to turn off the machine, and the charge is also very fast, which shortens the time, protects the battery, and protects yourself.

4.Don't overcharge, if it's original, it's okay, it will automatically standby after being fully charged, at this time the electricity used by the mobile phone is in the battery, if it is not original, the damage to the mobile phone battery is very large.

5.Don't wait until the battery runs out to charge, lithium electronics has a natural "self-destruct program" to reimburse the battery that has been completely drained, which is great from a safety point of view. But to do this, everyone is just a gesture, don't let the battery run out, the battery will become less and less durable after a long time.
