Fast charging will increase the heat of the battery during charging and speed up the movement of lithium ions in the battery, so in theory it will damage the battery more than ordinary slow charging. But now the batteries of mobile phones are relatively large. Even the battery capacity of iPhone X has reached 2716mAh. Even if there is loss due to fast charging, it will not have a significant impact on battery life. As for what you said about the battery capacity dropping by 3 in 15 days, it is indeed abnormal. The specific reasons can be speculated from the following aspects:
1. Excessive use of mobile phone batteries. According to the description of the subject, charging 2 to 3 times a day is relatively rare. Because the iPhone X battery insists on charging once a day according to normal usage habits, it is not a big problem. But if you use it intensively and need to charge it 2 or 3 times a day, and use a lot of power each time, then it is equivalent to 3 charge-discharge cycles a day, and 15 days is equivalent to one and a half months under normal circumstances. It is true. May cause battery consumption to accelerate. Because under normal circumstances, the battery's charge and discharge cycle is 600 to 800 times. Whenever the battery is used from 100 to 0 and then charged to 100, it is equivalent to a loss of cycle life.
2. Wrong charging habits. Some users use their mobile phones a lot. In order to avoid running out of power at critical moments, they are accustomed to plugging their mobile phones into the charger and charging them while playing games. In fact, under normal circumstances, the battery does not participate in discharge when the mobile phone is plugged into the charger, which will not affect the battery life. However, if you play games while charging when the battery is not fully charged, the charging speed will slow down and the temperature of the battery will increase. In particular, the heat dissipation conditions of iPhone X are not very good to begin with, and it easily gets hot while playing games. Under the superposition of many factors, the temperature inside the fuselage will exceed the limit that the battery can withstand, thus seriously affecting the life of the battery.
Therefore, if you must charge your mobile phone at the same time, it is best to use the original slow charging charger, because the slow charging power is small, the heat is low, and the impact on the battery is also small. It will be smaller.
3. The output power of the charger is unstable. Using some unqualified third-party chargers and data cables may cause unstable charging power and damage the battery. However, Lulian is also a regular brand, and if Momis’ data cable has passed MFi certification, it is unlikely that this will happen. If you are worried, you can buy the 18W USB PD charger and dedicated USB TYPE-C to Lightning data cable from Apple’s official website, but the price is relatively expensive.
In general, although the battery consumption of 3 in 15 days is a bit abnormal, it is also within the acceptable range. It is recommended to continue to observe and shorten the frequency of charging every day, and it is best to charge when there is still about 30% of the battery left. Do not wait for the battery to run out and automatically shut down before charging, which also consumes a lot of battery.
Currently, the fast charging technologies on the market are mainly divided into two types: high voltage and low voltage and high current. Apple this time uses 14.5V high voltage fast charging on iPhone X and iPhone 8/8 Plus, which is popular in the market. Qualcomm QC fast charging is also a high-voltage fast charging technology, which has been verified for many years, so it is a mature technology and not a new feature introduced by Apple.
We The impact on battery life during use is generally caused by temperature. When a lithium battery is working, a chemical reaction must occur inside to release electrical energy. When charging and discharging, temperature will affect this process, thereby affecting battery performance and life. But when charging, the high-voltage fast charging of iPhone
Of course, there are no absolutes. Fast charging does have some impact on battery life, but this impact is actually relatively low. Compared with the battery loss caused by daily use and charging, it is basically not obvious. According to the battery life of the iPhone, it usually needs to be replaced after more than a year of normal use. Even if you use fast charging, this loss will not be accelerated.
It should be noted that Apple will only perform fast charging when the battery is low. After the battery is charged to more than 80%, the charging will return to the original 5V/1A for charging, so Apple has They will consider setting restrictions on fast charging for mobile phones and batteries. As consumers, we just need to follow the instructions.
Of course, in order to protect the battery and avoid other safety hazards, it is best to use Apple’s official fast charging combination to charge iPhone X, including a 29W USB-C power adapter priced at 388 yuan, plus The last USB-C to Lightning data cable sold for 188 yuan, with a total price of 576 yuan.
Fast charging will increase the heat of the battery during charging and speed up the movement of lithium electrons in the battery, so in theory it will damage the battery more than ordinary slow charging
But today’s mobile phones The batteries are relatively large, and the battery capacity of iPhone X has reached 2716mAh. Even if there is loss due to fast charging, it will not have a significant impact on battery life.
If the battery capacity dropped by 3 in 15 days, it is indeed abnormal. It is recommended to continue to observe and shorten the frequency of charging every day. It is recommended to charge when the battery is about 30%. Do not wait for the battery to run out and automatically shut down before charging. This is also very battery-consuming. The principle of fast charging of mobile phones
is nothing more than increasing the charging power by increasing the voltage or current, thereby shortening the time for charging the mobile phone. Therefore, if the voltage or current is too high, it will definitely be harmful to the battery. Of course, the current fast charging technology is more mature than before, but it is still harmful. I once used Apple’s official 18W fast charger to charge my phone, but after half a month the battery health dropped by 1.
Nowadays, the battery capacity of mobile phones is getting larger and larger, generally 2000~4200mAh. As the battery capacity of mobile phones increases, the charging speed of mobile phones will slow down, so There will be current fast charging. Because the output is the same but the capacity is different, the current and voltage will be increased to achieve the purpose of fast charging. The technology of reducing charging time has become very common.
Under the first 50% of power, Apple's iPhone X uses fast charging to charge more than three times faster than the traditional 5W charging head. When using a USB PD fast charging head and USB-C to Lighting dedicated fast charging line, it only takes 30 minutes to charge iPhone Apple's original charging head can only charge 1 battery to 19 batteries after 30 minutes, and it takes 3 hours and 22 minutes to fully charge 100 batteries. As you can see here, Apple iPhone X models fully support the USB PD fast charging protocol. And when using the fast charging protocol, although the total charging time is only 1 hour faster, the key thing is that when the phone is almost out of power, you can charge the phone at a faster speed (for example, 30 minutes). When the battery is half full, you can safely take your phone out to work for 3-4 hours. However, if you use the ancestral 5W charging head, it still fails to break through the 20 iPhone battery warning line, which is exactly how fast iPhoneX is used. full meaning.
So I still recommend buying Apple’s official PD fast charging and data cables
The current and voltage adaptation are the best, so basically there won’t be too big a battery. Impact on health. Third-party chargers and data cables may cause unstable charging power and cause battery damage.
The above is my personal opinion, experience and summary. I hope it can help everyone. If you have different opinions, please leave a message in the comment area for discussion.
Judging from the author’s experience, using iPhone X is quite harmful to the battery. In fact, not just Apple phones, but any brand of mobile phone that often uses fast charging will cause serious damage to the battery.
To put it bluntly, the principle of fast charging of mobile phones is nothing more than increasing the charging power by increasing the voltage or current, thereby shortening the charging time of the mobile phone. It is not difficult to see from this that if the voltage or current is too high, it will definitely cause damage to the battery. Of course, the current fast charging technology is relatively mature, but it is still harmful.
The author is using iPhone 8 Plus, which supports 18W fast charging like iPhone X. I once used Apple’s official 18W fast charger to charge my phone, but after half a month, the battery health dropped by 1%. The subject of the question is that after using it for 15 days, the battery health dropped by 3.
According to the subject’s battery health decline rate, it basically drops by 6 in a month. Based on this calculation, it will take more than 3 months for the battery health to drop to 80, which is indeed abnormal. It is recommended that the subject use Apple’s official 18W charger and Apple’s official charging cable.
The author recommends that if there are no special circumstances, it is recommended to use the normal charging mode. Although fast charging shortens the charging speed, it is still harmful to the battery after all.
I have used two 18W PD fast charging heads. The key is that they are not the original iPhone charging heads. Let’s talk about their performance in general!
I am currently using iPhone X, and the fast charging heads currently used are divided into two types:
At present, I think it is the stability and speed of Nut’s 18W fast charging. It will be higher. I purchased a package from Greenlink and added a PD cable, but I found that during charging, it was not as good as nut charging.
As for the Nut mobile phone, I discovered after buying it that it did not use a USB-C to Lightning cable, so I spent another 145 yuan to buy a charging cable from the official website.
These aspects make me think that charging cables are very important for fast charging of mobile phones. So, does fast charging have any impact on mobile phones?
How long did it take to drop 3? New phone? Anyway, I have been using it normally, and it only takes a few months to remove it.
So will PD fast charging damage the battery? Let me share my opinion below:
Charging will cause damage to the battery. PD fast charging theoretically damages the battery more than ordinary slow charging. When using PD fast charging, the voltage and current of the battery are higher than Generally, when charging is high during normal charging, it will increase the heat of the battery and speed up the lithium ion in the battery. For example, the battery capacity of iPhone service life, so this impact is negligible and will not have a significant impact on battery life.
Fast charging shortens the charging time and also brings greater convenience. Generally speaking, the advantages outweigh the disadvantages. Although PD fast charging will not cause great harm to the battery, the prerequisite is that it meets applicable standards and And CCC certified power adapter.
Here I recommend several certified brands to you, Anker Nano, Green Alliance, Zimi, Bull, Baseus, Pinsheng. You can refer to the power supported by the mobile phone before purchasing.
Using the ancestral 5W iPhone is the most battery-saving! Why do I say this? I have two mobile phones, one is a 7plus and the other is an 8plus. My 7plus has always been charged with a 5W charging head, and the 8plus has been charged with a 12WiPad charging head. I bought both phones just after they were released. In other words, I used the 7plus for a year before I bought it. So far, the 8plus has a battery capacity of 93, while the 8plus has only 86. Both phones have the same usage conditions, and they are both charging and unplugging when the phone is full.
Fast charging will increase the battery capacity during charging. It absorbs heat and accelerates the movement of lithium ions in the battery, so in theory it is more harmful to the battery than ordinary slow charging. But now the batteries of mobile phones are relatively large. Even the battery capacity of iPhone X has reached 2716mAh. Even if there is loss due to fast charging, it will not have a significant impact on battery life. As for what someone said that the battery capacity dropped by 3 in 15 days, it is indeed abnormal. The specific reasons can be speculated from the following aspects:
1. Excessive use of mobile phone batteries. According to the description of the subject, charging 2 to 3 times a day is relatively rare.

But if you use it intensively and need to charge it 2 or 3 times a day, and use a lot of power each time, then it is equivalent to 3 charge-discharge cycles a day, and 15 days is equivalent to one and a half months under normal circumstances. It is true. May cause battery consumption to accelerate. Because under normal circumstances, the battery's charge and discharge cycle is 600 to 800 times. Whenever the battery is used from 100 to 0 and then charged to 100, it is equivalent to a loss of cycle life.
2. Wrong charging habits. Some users use their mobile phones a lot. In order to avoid running out of power at critical moments, they are accustomed to plugging their mobile phones into the charger and charging them while playing games. In fact, under normal circumstances, the battery does not participate in discharge when the mobile phone is plugged into the charger, which will not affect the battery life.

Therefore, if you must charge your phone at the same time, it is best to use the original slow charging charger, because the slow charging power is small, the heat is low, and the impact on the battery will be smaller.
This situation is actually abnormal. It is recommended to use more software to test it first. If it still exists, return to the factory for testing. First of all, fast charging will definitely damage the battery. This is determined by physical properties and cannot be avoided through operation. The principle is that fast charging will increase the heat of the battery during charging and accelerate the movement of chemical molecules in the battery, resulting in greater loss than normal batteries. So it cannot be avoided here. Also, what is PD fast charging? The full name of PD should be called USB Power Delivery Specification, which is a fast charging standard protocol launched by the USB standardization organization. This protocol uses USB because our charging is actually through USB sockets. As long as the USB socket supports fast charging, it must be certified by the PD socket. Therefore, through such a unified protocol, we can All mobile phone users can better enjoy fast charging technology, making it convenient for everyone to use.
Apple actually started using PD fast charging in iPhone 8. Therefore, Apple users also bid farewell to the era of Wannian 5V1A. Battery life no longer degrades the iPhone experience. In addition, if you use an inferior charger when using PD fast charging, it will not be able to provide stable charging efficiency for the battery. It also causes irreversible damage to the battery.
Therefore, it is recommended to use Apple’s official fast charger when using it, although Apple is also known for not being cheap in accessories. But at least the quality is reliable and it can also protect your phone well. The most important thing is safety, after all, safety is priceless. The mobile phone is just a tool in our daily life, and it is a tool that can fulfill the responsibilities of a tool.
