I often use the 6 1w charging head of MacBook Pro to charge the iPhone XR, and the charging speed is unknown.
After using the mobile phone for 10 month, the battery is healthy 95%.
Yes, the specific performance is that the loss is relatively fast.
My 14 is 6, and the original battery has been used for 5 years. A few days ago, before I changed it myself.
Eight p's two years ago were still 94% healthy.
The person I bought with is only 86% healthy. She uses the charging head of the ipad.
I don't have any experience myself, but I have been using the original charging head.
Batteries are consumables. If they break down, replace them. Don't let it affect your normal life. I belong to the kind of person who doesn't worry about charging my mobile phone, so I always use 5w.
IPhone XR supports 18W fast charging, but it must be equipped with 5W charging head. It took more than two hours to charge. And many fruit powders also comfort themselves, in order to ensure the safety of the battery and make it more durable. Indeed, 18W fast charge will have a greater impact on the battery than 5W, but it can be completely ignored.
Apple 18W fast charge is 243 yuan, which is still very expensive. Generally, the fast charging configuration of 18W is 9v-2a/12v-1.5a. Compared with the configuration of 5W 5V- 1A, the voltage is much higher and the current is also improved. However, due to high voltage protection, the damage of voltage to the battery is not high. The main reason is that the current is large, which accelerates the loss of the battery. Generally speaking, fast charging is definitely more harmful to the battery than slow charging.
So this kind of battery damage is unacceptable? Obviously not. At present, domestic mobile phones are fast-charging, and the fastest single battery has reached 44W, but everyone still uses it well. In fact, for example, the battery consumption of 18W is one and a half years, and it is better to replace the battery afterwards. Then the 5W battery can be used for eight months at most a year, and the battery will not work. Then the difference between these three months is that the charging speed is increased by 2 times every day, saving more time. At the same time, according to the different usage habits of mobile phones, heavy users may have to replace their batteries in a year or so no matter what kind of charger they use, so why not use a faster charging speed?
Android phones are going faster and faster on fast charge, and the reason why Apple is slow to follow is cost consideration. After all, it costs more to use a higher fast charging charger. If fast charging is such a big problem, why did Apple Store introduce fast charging? Recent generations of iPhone support fast charging. Android phones have used fast charging models in recent years, and I haven't seen frequent battery changes. They are fine, too.

For most friends, because the price of Apple's mobile phone is too high, they will weigh it for a long time before buying it. When I buy it back, I will cherish its use, especially in charging!
Take the iPhone XR as an example. Although 5V/ 1A charger (5W) is standard, it actually supports 18W and 29W charging heads, so many friends have sprouted the idea of buying fast charging, but at the same time they are wondering whether fast charging will affect battery life. Come and have a look with me!
According to Apple official website, the iPhone XR uses a lithium-ion battery and supports fast charging mode, which can quickly charge the battery to 80%, and then switch to slow trickle charging. This charging mode not only allows the user to take out the mobile phone faster, but also prolongs the service life of the battery. Therefore, fast charging with 18w for iPhone XR will not affect battery life!
The factor that affects the battery life of Apple's mobile phone is the charging cycle: when the iPhone rushes from 0 to 100%, a charging cycle is completed at this time, and the battery charging cycle of the iPhone is generally between 500 and 600 times!
Here you have to understand that it is impossible for our mobile phone to be charged with 0% power every time. For example, the current power of mobile phones is 25%. When you rush to 100%, it is actually a charging cycle. It only uses the current period 100%-25%=75%. The next time you charge at any power level, just recharge.
Therefore, the life of the iPhone battery is related to the charging cycle, and the impact of fast charging on it is almost negligible, because Apple has long thought of this problem when it joined the fast charging mode!
If you play high-quality the glory of the king and use 18W fast charge at the same time, the damage to the battery is relatively large, so many netizens report that the health of the battery will drop to 90% before long. Let's talk about it in detail.
Mobile phone batteries are consumables, and the life of mobile phone batteries has a great relationship with users' daily habits. Mobile phone batteries are most afraid of two things: first, they are afraid of low-power charging, such as charging when the power is exhausted; The second is fear of high temperature.
The suitable charging temperature of lithium battery is 0~45 degrees, and the temperature of PD fast charging mobile phone is about 30 degrees. If you play a high-quality "chicken-eating game" at this time, the battery temperature will quickly rise above 40 degrees, causing great damage to the battery.
Use fast charge as little as possible. As long as conditions permit, my iphone 8p will be plugged in slowly (5V 1A 5W charger), and the charger will be plugged in all the time in the office and at home, and it is still 86% healthy.
The charging process of mobile phone is divided into three stages: constant current, constant voltage and trickle. Lithium batteries are suitable for shallow discharge and Wally. 80% charging of the mobile phone will not harm the battery. The lower the battery charge, the greater the heat and the shorter the battery life. Therefore, after the battery capacity reaches 100%, it will not generate heat when charging.
At present, most companies that provide fast charging solutions have not given the impact on battery life from the perspective of batteries. The national standard is that the capacity of the battery is above 80% after charging and discharging for 500 times.
It will affect it. . It is best to use the original charger. Generally, the universal charger takes more than 3 hours, and the original charger only takes 2 hours.
As a senior fruit powder and an iPhone 8 Plus user, let me briefly talk about this issue. In my opinion, the iPhone XR with 18W charger will hurt the battery more than the 5W charger.
Theoretically, both iPhone 8 Plus and iPhone XR support 18W fast charge, so using 18W fast charge should not harm the battery. However, in practical application, the author used Apple's original 18W charger to charge the iPhone 8 Plus, and found that the battery health declined rapidly.
From this, it is not difficult to judge that using 18W fast charge to charge iPhone XR will lead to a rapid decline in battery health. Out of curiosity, I used Apple's original 5W charger and found that the battery health declined slowly. Obviously, Apple's fast charging is still harmful to the battery.
However, I have also tested some Android phones, charging them with original fast charge and standard power charger, and found that fast charge also has a slight impact on battery life. It seems that fast charging does do some harm to the battery.
Because we are not sure how much damage fast charging will cause to the battery of Apple's mobile phone, I suggest that Apple should honestly use the 5W charger.
Answer: No. ..
Because mobile phone charging is controlled by mobile phone, not provided by charger. It has no effect on the mobile phone battery itself.
Just like eating. The charger is made at home. How much you eat is controlled by your brain, not the food you cook. These are two different things. Of course, the rice is too small to finish, that's another matter!
Today's smart phones will detect the load capacity of the charger. When the power of the charger meets the relevant fast charging protocol, the iPhone XR will charge according to the PD fast charging protocol, and the mobile phone will automatically let the charger load a higher current according to the fast charging protocol, so that fast charging can be started. Let's talk about the official charging parameters of iPhone XR, and fully support A 1720 charger (18W), A 1540 charger (29W), A 1882 charger (30W) and A17/Kloc.
But the maximum power allowed by iPhone is 18W, so even if you use A 17 19 charger (87 W). The peak power is about 18W, so don't expect the charging speed of 30W to be 30÷ 18= 1.67 times.
Apple fully supports the PD3.0 protocol from iPhone 8 and iPhone X, but because Apple's original charger is very expensive, all chargers compatible with PD protocol support Apple's mobile phone fast charging!
So all you have to do is choose a PD protocol charger that supports 18W and a USB-C lightning cable! Less than 30 yuan's Green Union CD 137 is enough.
So don't worry about battery problems when using fast charge!
Your support is my motivation.
Here is TASTER Technology's answer. Thank you for reading.
First, it is certain that fast charging will last longer than ordinary charging.
Second, whether to harm the battery and how to reduce the battery loss are things that Apple needs to consider, not for a consumer to consider.
Speaking of this question, I think of a very classic question:
There are many sayings on the Internet that shooting video by SLR will harm cmos and components and greatly reduce the service life of SLR. Scared many white people.
Later, after "research", it was found that taking pictures with SLR would also damage cmos and components, so it is the best way to minimize the loss and maturity of cmos and various components and put SLR in the safe.
But interestingly, SLR has the function of shooting video. Since the manufacturer has added this function, these problems must be considered. Your mobile phone camera also has cmos and various components, which takes a long time. I've never seen a cell phone break down because of this.
To sum up: since the manufacturer made it for you, the instructions can be used.
In fact, this is a question of service life. It will take four or five years for one of your smartphones to be scrapped. The service life of all parts of your mobile phone is long, and the loss during normal use is small, which does not affect the normal use.
For example, iPhone XR is equipped with 18W fast charge, and Apple has considered battery loss. According to their test, according to a person's normal habits, the mobile phone is charged x times a day for x years, and the battery loss is within an acceptable range. This technology can be applied to mobile phones.
What's more, Apple's application of fast charging technology is still relatively "stable". After charging 10W for 10,000 years, the fast charging of 18W was finally achieved, but many models still don't deserve the fast charging suit. Moreover, the "Optimize battery charging" option will be turned on by default in the IOS system. After being turned on, the iPhone will learn the user's daily charging mode and regret to stop charging when the power is 80%, which is the "trickle charging" in the popular power-saving software before, which protects the battery life to a certain extent.
Using fast charge can greatly improve the user's time. IPhone also supports low-power wireless charging, which allows you to charge with low power through wireless charging before going to bed, and it is just full when you wake up, which not only protects the battery, but also won't be disturbed by your mobile phone (I guess this is the reason).
Android manufacturers are developing rapidly in fast charging. At present, the highest record has reached the 120W super flash charging of vivo (it has not been specifically applied to the models on sale), the 60W fast charging of OPPO has been commercialized, and the wireless fast charging has also reached the 30W of Xiaomi.
Different from the previous theory of charging before going to bed, domestic manufacturers usually give an example of fast charging: you wake up in the morning and find that your mobile phone is dead, charge it when you brush your teeth, charge it when you drive to work, and your mobile phone is full.
There is no difference between the two ideas, but it is really useless to charge quickly. I started iQOO at the beginning of 20 19. After 44W fast charging, I feel that many mobile phones are really slow to charge. Now I have been using iPhone 1 1 Pro for a long time, and I am used to it.
Just charge it, okay? I think it's a good thing that fast charging technology can be used. I think there are three main points:
1. Whether fast charging technology is safe or not, every mobile phone manufacturer has said: fast charging protection, overload protection, etc. I won't go into details here. Since OPPO started fast charging, mobile phones rarely have problems due to fast charging.
2. Acceptability of battery loss: For example, charging with 50W for one year, battery loss 10%, I think it is quite acceptable, similar to "sacrifice" in Warcraft.
3. Practical question: For example, is Tesla charging fast? It can run more than 500 kilometers in an hour and a half, which is beautiful, but the charger is also big, so it is inconvenient to carry a mobile phone. The bigger the charging power, the bigger the charging head, so several mobile phone manufacturers have developed new charging technology, which is also the reason why they don't sell it. The charging head is as big as a charging treasure, so you don't need to do fast charging. In order to solve this problem, we need to use new technologies, such as the recently popular GaN charger.
Please pay attention to tasting technology for more views.
There is absolutely no such thing as charging the battery quickly, unless your charger is a cottage, that is, the current amplitude is very unstable, and there is no charging head and a cottage line that is not recognized by MFi, which may damage the battery and burn out the IC. Fast charging means fast charging at the front and slow charging at the back until the charging is completed. Moreover, Apple's power management chip is also carefully designed, and the maximum is only 18W, unlike some brands that pursue high brightness regardless of the safety of consumers, and the charging power is as high as 45W, which is very' dangerous'.
