The reason why Apple’s mobile phone can’t be charged and its solution [detailed explanation]

  【Apple’s mobile phone can’t charge】 Many fruit powders find that sometimes the power cord is plugged into the mobile phone, and the iPhone also displays the charging symbol, but the mobile phone just can’t charge it. Why? Xiaobian will answer for you!

Causes and solutions of Apple’s mobile phone charging failure

  1, excessive battery loss, has been completely damaged.

  Generally speaking, this kind of situation is rare. You can check the battery health through our education first. In normal use, the battery health of iPhone is above 85% within one year and above 75% within two years. But if you use it for one year and it has dropped by 80%, there are only two possibilities. One is that you have bought a fake, and the other is that you have often committed the behavior of damaging the battery mentioned in the previous chapter. I’ve met someone who charges the battery almost several times a day because of playing card games. As a result, the battery health of mobile phones has dropped to 78% in less than half a year.

  2. The battery management IC is damaged

  This situation is mostly due to the fact that the mobile phone falls to the ground, which leads to the disconnection of the motherboard components, and the probability is very small. If the battery can’t be charged and it is said that the motherboard is damaged, the store will charge you more than 500 so-called motherboard replacement fees. In fact, it only needs more than 100 replacement power IC.

  3. The charger is not original, and the charging cable is damaged.

  This is easy to handle, just ask someone for an original iPhone charger and charging cable and try it.

  4, mobile phone system failure

  At the same time, press the power button +Home button until the Apple Logo appears, and forcibly restart the iPhone, which should be solved.

  5. The gold finger of the charging port is oxidized or dirty.

  Scrape the gold finger part of the charging port on the iPhone with the Sim card pin attached to the iPhone, and try to scrape off some oxides on it (generally, the old iPhone that has this problem is definitely used for more than 1-2 years).

Normal charging time of iPhone

  Under normal circumstances, it takes 4-5 hours for the iPhone to be fully charged. It is recommended that you use the original charger. Charging with iPad charger can greatly shorten the charging time.

IPhone charging precautions

  1. It is not necessary to charge the 1.iPhone for 12 hours for the first time, but remember to charge it when the screen prompts 10% for the first time, and don’t run out of power;

  2. After that, it can be charged at any power, and it is not necessary to wait until the power prompt is too low;

  3. It is best to have a complete charging and discharging process once a week. If you can’t do it every week, at least make sure that your iPhone goes through at least one charging cycle every month, in order to expand the battery capacity;

  4. Although the iPhone also has the function of overshoot protection, it is still recommended to avoid charging for too long, especially overnight. Because the charging time is too long, it will greatly shorten the service life of the battery;

  If you can’t solve the problem by using the above methods, please go to Apple’s after-sales service or professional maintenance organization for maintenance. If you have more questions, please continue to pay attention to the IT Encyclopedia column of Pacific Computer Network.

LI has gone negative again, and employees from various departments have left!

The new force of making cars-there is negative news again.

Recently, according to a number of media reports, the ideal internal multi-department employees leave their jobs, and the fuse is the discount of employee year-end awards. According to the news, "ideally, all employees’ year-end bonus in 2022 is not as good as before, and they only get half of their monthly salary, and a few get 13 salaries."

?

In fact, there have been many negative news in LI. In addition to product problems, in May last year, the company was once exposed as "breaking the contract to recruit students", and LI’s response was "business has been adjusted, providing compensation for post transfer or termination".

?

?

A star company has repeatedly stood on the cusp of public opinion in employee relations. Has the personnel department in LI noticed it?

?

In fact, the "generosity" of an enterprise is closely related to the development of the enterprise itself and the prosperity of the industry.

It is understood that in 2022, it is a year of "dim stars" for the new forces making cars. Last year, the sales KPI of "Three Musketeers" failed. Among them, LI’s sales target completion rate was 78.35%, lower than (81.6%) and higher than (48.28%).

?

Generally speaking, the end of the year is the time when car companies concentrate their firepower on sprinting KPI. Embarrassed, the year-end data shows that the sales of "Wei Xiaoli" still failed to achieve a big outbreak. If the income of car companies cannot cover the operating costs, it is more difficult to make profits.

?

At present, Weilai, Tucki and Ideality are still at a loss stage, and the key to turning losses is whether they can expand sales. The logic behind it is: sales growth-enterprise operating income increase, hedging operating costs-enterprise improving profitability.

?

From the reasons, in 2022, the sales KPI of many new car-making forces failed, which may be the result of intensified competition in the industry and the resonance of car companies themselves.

?

After entering 2023, the sales volume of the new forces of car-making has differentiated.

In January this year, LI sold 15,141 vehicles (with an average daily sales of 488.4 vehicles), up 23.4% year-on-year and down 28.69% month-on-month. It is worth mentioning that LI is the only car company with sales exceeding 10,000 and positive growth year-on-year.

?

LI has a strong sales volume. It is believed that the main extended-range electric vehicle matches the current market demand, and the second is that it has a good grasp of the market rhythm and vehicle relay.

?

Reflected in the stock price, LI rose more vigorously. Since the beginning of January this year, LI’s share price has increased by 22.94%. In the same period, Weilai Automobile and Xpeng Motors increased by 14.77% and 5.63%.

However, for investors in LI, they are not completely at ease. China, as one of the largest consumer markets of new energy vehicles, has witnessed a hundred flowers of new energy brands, and the selectivity of consumers has greatly increased. As a result, there are more and more competitors of the new car-making forces, and their "scarcity" value is also decreasing.

The report of the Association pointed out that "the growth of new energy sales has reached a bottleneck stage … (Future) sales growth will be a serious problem".

In this stock game market, LI has to face the competitive pressure from traditional automobile manufacturers.

In the future, we will continue to pay attention to how LI will expand its sales and when it will turn losses into profits.
