How to charge the iPhone 4 and how to charge the IPHONE4 properly?

Use a power cord or a universal charger.

Generally speaking, this is what it looks like, and you can charge it whenever you want.

However, if you do the following, you can effectively maintain the battery.

1。When the power is less than 20%, you can consider charging, it is best not to charge it below 10%, and never run out of power.

2。Once a month, charge from below 20% to 100% and then then rush for 1-2 hours, because Apple designs the battery to be fast charging for the first 80% of the battery, and it can be fully charged in 2 hours, but in fact, the next 20% still needs 2 hours to charge to 100% in the real sense.

3。When you start charging at any time, it is best to charge until the plug shows 100% and then unplug it.

On the contrary, use it until it is less than 20% and then recharge.

Now the battery has no memory, how to flush and how to flush, regardless of whether it is the first time to charge or the first time, and I don't care if you use it again and again when you charge.

The data cable is connected to the plug, and it is OK to connect it to the socket or the data cable is directly connected to the computer!

Charge with a dedicated charger.

Plug in the charger or connect the computer with a data cable to charge.

The working process of the battery receiving electrical energy from the external circuit and converting it into the chemical energy of the battery. After the energy of the battery is consumed by discharge, it can be restored by charging and can be re-discharged, constituting a charge-discharge cycle. Generally, it is charged with DC current (also with asymmetric AC current or pulse current).

1. There is no relationship between the mobile phone and the charging time, so the mobile phone can be charged at any time without limit;

2. Apple mobile phones are different from ordinary mobile phones, if the mobile phone is out of power, it cannot be flushed and used, and it needs to be flushed for a while before it can be turned on and used;

3. When the mobile phone is first bought, it needs to be fully charged twice and all the power discharged to release the power capacity to the maximum;

4. The batteries have a certain service life, and after two or three years, it is best to change to a mobile phone, sell the mobile phone, and add some money to buy a new one;

5. Do not use other charging plugs for charging, it is best to use the charging adapter that comes with the Apple mobile phone;

6. It is forbidden to play ** when charging, because when charging, the mobile phone will heat up, which is very dangerous. I have had it before, when charging, I hit **, causing **;

7. It is best to try to do the process of full charge and discharge once a month, which can improve the durability of the battery.

It is okay to charge with a computer or an outlet, but do not unplug the power supply often when charging, it is best to unplug it when it is full. Unless you're in a hurry, it doesn't matter once or twice. Because Apple's battery has memory, and this memory is related to recording battery life, if it is plugged in once and fully charged, even if the battery life is damaged once, it will be remembered.

If it is often unplugged before it is full, the battery will often be memorized once, and it will lose its life. The battery life of the iPhone 4 is about 650 to 850 times. For the sake of battery life, it is better not to charge and unplug it all the time.

Apple's battery has memory? Apple is so powerful, oh, you can make the lithium battery have a memory function! Ou buy embarrassed!

In this case, the last 1% should be charged for about 10 minutes, and then when the battery level shows 100%, it will be completely charged for about half an hour.

Meaning of full charge: Apple calls it a full charge after the charging cycle is completed.

1. If the amount of power used (discharged) reaches 100% of the battery capacity, a charging cycle is completed, but not necessarily by a single charge.

2. For example, you may use 75% of your battery during the day and then fully charge your device overnight. If 25% of the battery is used the next day, the total discharge will reach 100%, thus completing a charging cycle in two days. It may also take a few days to complete a charging cycle.

Most people have a misunderstanding, you have to use it to charge it after shutting down to be fully charged, in fact, this hurts the battery the most, there is no need, as long as you don't use the mobile phone when you can charge, the specific analysis can go to the Internet to search for lithium battery charging skills, and then there is that battery doctor is crippled, nothing, completely useless, something to cheat money.
