Apple charging common sense

1. What do you need to know about Apple's mobile phone battery charging?

Here are some tips for charging Apple's mobile phone battery: When charging for the first time, it is suggested that the battery is full, so it is best to keep charging for 15 minutes, and don't charge for too long; Use 20% less equipment before charging, which can reduce charging times and improve battery life. In addition, cut off the power supply when fully charged, and don't charge for too long. You must use Apple's own charger for charging, and don't use chargers of other products to avoid damaging iPhone devices. Finally, use USB to charge, which is better for lithium battery maintenance; Start charging when the power is lower than 20%, and charge it for a complete cycle after it is fully charged; To reduce the number of cycles, it is necessary to start charging as low as 20%. Finally, you can charge it regularly once a month. For example, after the device is automatically turned off, it can be recharged to full charge. This interval is best not to be too short.

2.2. What are the tips for iPhone charging?

Regardless of whether a lithium battery is used or not, the "battery life" is generally only three to five years at most. After 500 charge and discharge cycles, the properly maintained iPhone battery can still retain 80% of the original battery capacity. Here, charging from 0% to 100% and then using it to 0% is a complete charging and discharging cycle, from 50% to 100%.

2. The most important thing of lithium battery is that it can't use automatic shutdown, which will accelerate its loss. Lithium batteries have a large loss at low power, and can last for the longest time if they are at 40%-60% power for a long time. If you don't use the iPhone for a period of time, please charge the battery to 50% before storing it.

3. After the new battery is charged, it will go to sleep after a period of time. At this time, if the capacity is lower than the normal value, the service time will be shortened. However, lithium batteries are easy to activate. After two or three normal charge and discharge cycles, the battery can be activated and return to normal capacity. If the battery capacity is very low, it can be fully charged for two and a half hours to three hours (sometimes it just shows full, but it is actually not full, which is why the battery capacity sometimes changes when the phone is restarted, and it will be fully charged for 20 minutes after 100% is displayed).

4. During normal use, you can charge the battery as needed. Don't worry that downloading software from the computer often will reduce the battery life, because it has little effect on the charging and discharging cycle. Generally, it is best to charge about 30% or 40%. When the battery is low, you should charge it in time. Try not to use batteries within 10%. If it happens, don't worry, just reduce the number of times this happens in the future.

Lithium batteries are not only afraid of low power, but also afraid of overheating, especially when charging. When the charge is 0-90%, the battery will be charged quickly, and then the battery will be heated. Finally, 10% will be collected by Trickle. At this time, the current is very low, and the temperature of the battery will gradually decrease. Everyone can feel that the battery will be much better when charging, so it is recommended that you don't run programs with heavy loads when charging. Generally speaking, don't spend too much time answering the phone, texting and surfing the Internet with wifi. It would be much better if the temperature of the machine was not very high.

6. There is no harm in charging all night, because the charger will cut off the current after it is full, and it will not cause overcharging. When the mobile phone is not in use, the standby current is very small, but it is still discharging, so when I get up in the morning and unplug the data cable, I see that the power is 100%, but it is completely durable without charging for three hours.

In addition, there will be a small current when the charger is empty. In order to protect the environment and avoid unnecessary waste, you can unplug the charger after it is fully charged. Some power-saving settings of iPhone Knowing the usage information of iPhone will help you to better manage the battery life.

To view the usage statistics of iPhone, go to Usage: Usage Time: the time that iPhone woke up and used since the last full charge under Settings General Statistics.

When the screen is unlocked, the iPhone is awake. Standby time: the startup time of the iPhone since it was fully charged last time, including the time when the phone was asleep.

When you use your mobile phone for the first time, you need to charge it to 100% before the data will be displayed here. Don't charge halfway after it is full. The data shown here is valid and can be used as a reference. In most cases, after optimization, the mobile phone can be used for 6-8 hours and stand by for more than ten hours, so the battery is in good condition.

You don't have to worry about how much power will be consumed and how long it will be used for one night (for example, 1%), because there are many factors, such as system version, system settings, software, sim card and signal, charging situation, battery power and so on. These are all within the normal range. The simplest and most effective way is to turn off the battery percentage display, so there won't be so much trouble. The following is my personal system settings, you can refer to 1, try to use wifi, and use 3G less. 3G consumes a lot of power, so mobile phones will be very hot.

2. Setup-Notification Center. All software except system programs and chat software choose to turn off notifications. 3. General-About this machine-Diagnosis and dosage, choose not to send.

4. General -siri, turn it off. 5. General-background application is refreshed and closed completely.

6. General-Date and time, turn off the automatic setting, and manually select Beijing as the time zone. 7, Settings-wallpaper and brightness, turn off the automatic brightness level, and choose the brightness that suits you according to your needs. You adjust it to one-fifth during the day and directly to the lowest at night.

8.Set-password has nothing to do with power saving, but it is very useful. When you need a password, you can choose one hour or four hours, which means that after waiting for a long time, you need to enter the password when you open the screen, and you don't need to unlock it all the time, which is very inconvenient for you. 9. Settings-Privacy, location service is turned on, and only required programs, such as maps, are allowed to run.

All system services can be shut down without any impact. 10, set -icloud, open address book, memo, find my iphone, and everything else can be closed. Online backup of photos is very slow, so it is recommended to synchronize to the computer.

Cloud backup in storage and backup is also turned off, and annoying prompts often appear. 1 1, Settings -itunes Store and app store. It is recommended to turn off automatic downloading and the use of cellular mobile data. This will not affect the manual download in the store.

12, on the desktop, the camera, weather, compass and stock market can be opened and positioned as needed. Others are the default settings. It is best to restore all the settings in Settings-General-Restore and then reset them.

3.3. What are the basic knowledge of iPhone charging?

Human body's response to electric current:

8 ~ 100 ma hand is difficult to get rid of the electrode, and there is a sharp pain (finger joint).

At 20~25mA, the hand became paralyzed rapidly, and it was impossible to get rid of the electrode automatically, making it difficult to breathe.

50~80mA dyspnea and atrial fibrillation.

90 ~1000 ma respiratory paralysis, three seconds later, the heart began to paralyze and stopped beating.

It is generally believed that the lethal current does not exceed 50mA, so the leakage switch is generally designed as 30mA, and the human body resistance varies greatly, ranging from 500- 10k according to the dry skin condition, but it is generally estimated as 800 ohms, so it is generally set as 36v safe voltage. However, if it is in a particularly humid environment, 36v is not safe. Some people with rough skin and dry insulation resistance may not be electrocuted at 50v, especially sparrows.

There's a problem. Why does a 5v charger electrocute people? This is because all the 5v chargers we use every day are converted from 220v at home through electronic transformers. In order to reduce the high-frequency radiation interference, most electronic switching power supplies are equipped with a small capacitor between the incoming line (220v) and the outgoing line (5v) for grounding the high-frequency interference elements, which is also the reason why the metal parts of our mobile phones are numb when charging! But because this capacitor is very small, its equivalent impedance is very large, that is, the leakage current is very small, which will only cause inductance, but not enough to electrocute people. However, what if the capacitor fails and is subsequently damaged? Then the 220v communication will directly enter the mobile phone and electrocute people (the friend who said that 220v electrocution is difficult, try it yourself, I dare not! )。 Moreover, the incoming line 220v enters the low voltage side (5v), and this capacitor is not the only path (some chargers do not have this capacitor). There is also an original component that is easy to connect electricity, that is, a breakdown short circuit of the transformer, which is more common. Others may include unreasonable wiring, damaged short circuit and so on.

Therefore, it is entirely possible to electrocute people with a 5v charger, and whether or not to make rumors about black apples is not included in this discussion.

4.4. When 4.4.iphone is charging

When using a lithium battery, it should be noted that after a period of use, the battery will enter a dormant state, and when the capacity is lower than the normal value, the use time will also be shortened.

However, the lithium battery is easy to activate, and it can be activated after 3-5 normal charge and discharge cycles to restore normal capacity. Because of the characteristics of lithium battery itself, it has almost no memory effect.

Therefore, the new lithium battery in the user's mobile phone does not need special methods and equipment in the activation process. Not only in theory, but also from my own practice, it is best to use the standard method to charge this "natural activation" way from the beginning.

For the "activation" of lithium batteries, there are many sayings: the charging time must exceed 12 hours, and it must be repeated three times before the battery can be activated. This statement that "the first three charges should last more than 12 hours" is obviously a continuation of the statement of nickel batteries (such as nickel cadmium and nickel hydrogen).

Therefore, this statement can be said to have been misinformed from the beginning. The charging and discharging characteristics of lithium batteries and nickel batteries are very different. It can be clearly told that all the serious and formal technical materials I have consulted emphasize that overcharge and overdischarge will do great harm to lithium batteries, especially liquid lithium-ion batteries.

Therefore, it is best to charge according to the standard time and method, especially not more than 12 hours. Usually, the charging method introduced in the mobile phone manual is the standard charging method suitable for this mobile phone.

In addition, 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 65,438+00 hours in the nickel charger. In other words, if your lithium battery is fully charged, it is also charged in white on the charger.

None of us can guarantee that the characteristics of the battery charge and discharge protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long-term charging.

In addition, for some mobile phones, if the charger is not taken out after charging for more than a certain period of time, the system will not only stop charging, but also start discharging-charging cycle. Perhaps manufacturers have their own purposes, but it is obviously unfavorable to the life of batteries and mobile phones/chargers.

At the same time, long-term charging takes a long time, often at night, but according to the situation of China power grid, the voltage at night in many places is relatively high and fluctuates greatly. As mentioned above, lithium batteries are very expensive, and their ability to withstand charging and discharging fluctuations is much worse than that of nickel batteries, which brings additional dangers.

In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for overdischarge, and overdischarge is also very unfavorable to lithium batteries. This leads to the following problems.

To sum up, the correct practice of lithium battery mobile phone comes down to the following points: ① Charge according to standard time and procedure, even for the first three times; 2. When there is a hint that the battery of the mobile phone is too low, you should try to start charging in time; ③ The activation of lithium battery does not need special methods, and it will be activated naturally during the normal use of the mobile phone. If you insist on using the popular method of "the first three times of 65438 +02 hours of long charge activation", it will not actually work.

Therefore, it is wrong to pursue 12 charging for a short period of time and use the lithium battery mobile phone for automatic shutdown. If you did it according to the wrong statement before, please correct it in time, maybe it's not too late.

Of course, under the condition that the protection and control circuits of mobile phones and chargers are of good quality, the protection of lithium batteries is quite guaranteed. Therefore, understanding the charging rules is the key, and some concessions can be made in some cases.

For example, if you find that your mobile phone must be charged before going to bed at night, you can also start charging before going to bed. The key to the problem is that you should know what the correct method is and don't deliberately follow the wrong statement.

5. How much is the best charge for Apple's mobile phone?

1. In daily use, it is best not to use automatic shutdown for Apple mobile phones. Instead, it is best to charge the mobile phone when the battery is 20%-40%, and you can unplug it when it is full.

2. Early mobile phones used Ni-Cd batteries and Ni-MH batteries, which needed similar "activation". These batteries will have a "memory effect". When they are charged under incomplete discharge, they are easily overcharged. After a long time, users will feel that the power will run out soon, so it takes 65,438+02 hours to fully charge for the first time, and it is best to recharge when there is no power.

3. The battery used on 3.iphone is lithium-ion battery. Its initialization process has been completed at the time of manufacture, so it does not need to be activated when it is used. Lithium batteries also have no memory effect and can be charged at any time. If the mobile phone is turned off automatically, the internal voltage of the lithium battery will be too low due to excessive discharge, and it may not be able to start and charge. Therefore, lithium battery charging pays attention to "eat less and eat more", and frequent shallow charging and discharging is more helpful to prolong its life.

6.6. What are the tips for charging 6.6.iPhone 6?

2. Plug in the data cable first, and then plug in the socket.

Plug the data cable into the iPhone6 charging interface first, and then plug the dual-hole plug into the socket. It takes about 4 hours to fully charge the remaining 10% for the first time. The suitable temperature of the environment during charging is 10 -35 degrees. /kloc-charging below 0/0 degrees is slow! The ambient temperature exceeding 35 degrees will seriously reduce the effective capacity of the battery and cause irreparable damage.

3. Judge whether the battery is fully charged after shutdown.

How to judge whether it is full when charging is turned off? Press the Home button and a large battery icon will appear in the center of the screen. When there is no white lightning sign under the battery, it is completely full! When charging, the state is large battery, and there is a white lightning sign below the icon, indicating that it is charging. For the sake of equipment safety, another suggestion is to disconnect the charger in time when it is fully charged. It's no use charging more!

4. Don't unplug the cable after the battery is fully charged.

When fully charged, do not unplug the data cable or plug at this time! ! Then press and hold the power-on button normally for a short time, and a charging state diagram will appear quickly on the screen, and then a white iPhone logo will appear until it is turned on normally.

5. Fully charge and discharge after one month.

It can be fully charged and discharged once in about one month! The battery can be automatically turned off, then turned off and fully charged once. It is recommended not to charge while playing games when you start charging, which is not good for the battery.

6. Periodic charging and discharging

In order to keep the battery charged normally, please make sure to charge it at least once a month, that is, fully charge the battery, and then use it completely. You only need to charge and discharge the iphone6 once a month or so.

7.

The newly bought mobile phone battery needs to be charged for the first time 12 hours, and the first charging is the key to the battery life, because after the first charging, it has been running at full capacity for a period of time (i.e. 12 hours -3 hours), and the capacitance reaches the maximum value, and it can reach the maximum value after 3 hours of charging in the future. If it is less than 65,438+02 hours for the first time, the phone will display 65,430 hours even if it is charged for the first time.

Therefore, it is suggested that the first charging time is 12 hours. The battery light icon flashes three hours before charging (usually in the upper right corner of the mobile phone screen), and will not flash after three hours, which means it is fully charged.

Don't turn off the power even if the icon doesn't blink for the first time. In the future, as long as the icon doesn't flash, unplug the power and don't charge for a long time.

8.8. What is the basic knowledge of iPhone charging?

1, using original batteries

2. It doesn't matter if the phone overheats more than 50℃ after a long call.

3, the heat dissipation of the net cover is a misunderstanding because the mobile phone can't get moisture.

4, high temperature will not make the mobile phone battery explode.

5. Choose the correct charging method

6, mobile phone charging about 300 times, it is best to replace the battery.

7. It is better to unplug the plug when charging to 80%, rather than overcharge.

8. Don't watch videos while charging, and don't put them on your pillow at night.

9. Before charging, try to ensure that the battery is really exhausted.

10, there is no need to fully charge the new mobile phone for more than three times. This is suitable for nickel-chromium batteries, and mobile phones are lithium batteries.

1 1. If the mobile phone battery is improperly placed, such as touching conductive media such as keys and coins, it may cause the battery to be short-circuited and generate a large current in an instant, and the instantaneous temperature is likely to exceed 150℃, which may lead to explosion and other dangers.

9. Charge the newly bought apples

Now Apple uses a lithium battery, so it doesn't take 12 hours to charge for the first time like the previous mobile phone.

In theory, Apple charges 2. It can be fully charged in about 5 hours. The best time for Apple to charge for the first time is when it is fully charged (fully charged), and then it can be fully charged for another minute or so.

The following are some tips for charging Apple battery: 1, the first time charging, the prompt is full, it is best to keep charging for 30 minutes, and don't charge for too long; 2. Try to charge the equipment after the power consumption is less than 20%, which can reduce the charging times and improve the battery life. In addition, turn off the power supply when fully charged, and don't charge for too long; 3. Be sure to use Apple's own charger when charging, and don't use chargers of other products to avoid damaging iPhone devices; 4. Finally, use USB to charge, which will better maintain the lithium battery; 5. When the power is less than 20%, start charging until it is fully charged, that is, fully cycle charging; To reduce the number of cycles, it is necessary to start charging as low as 20%. Finally, you can charge regularly once a month. For example, after the device is automatically turned off, it can be recharged to full charge. This interval is best not to be too short. .
