What's wrong with using iPhone 12? -A comprehensive list of frequently asked questions in the use of iPhone12.

After the first release of iPhone 12, many friends have got it, but after using it, they found that iPhone 12 frequently had problems, such as degaussing, trimming, paint peeling and so on. Let's take a look with me. Give my friends who bought iphone 12 a vaccination in advance. I hope I can help you.

At present, with the first batch of iPhone 12 and iPhone 12Pro purchased by consumers being delivered to consumers one after another, the real experience of iPhone 12 and iPhone 12Pro in actual use has also been fed back. At present, from the real experience of consumers, there are still various problems in IPhone 12 and iPhone 12Pro, and the real user experience of iPhone 12 and iPhone 12Pro is still very poor, not as good as expected.

1.iPhone 12 border is easy to paint off.

In addition, the problems that everyone is more concerned about have appeared again. Some netizens said that the border of iPhone 12 was painted off. This photo of painted iPhone 12 was taken in an Apple store. This iPhone 12 is a prototype on the booth. At present, the reasonable explanation for the phenomenon of paint falling off the border of iPhone 12 is that too many people play with it and frequently touch the border. However, judging from the photos, the border of this iPhone 12 has no obvious bulge, and it is unlikely that the paint will come off because of the bulge. However, it is still unknown whether the paint peeling phenomenon of iPhone 12 is a case or a common phenomenon. This conclusion needs waiting time to verify.

2. Insufficient battery life

For the endurance of iPhone 12 and iPhone 12Pro, at present, netizens generally said that it was really not so good after the experience. There are many reasons for the poor endurance of iPhone 12 and iPhone 12Pro. For example, first, supporting 5G networks consumes more power than 4G networks. The battery capacity shrinkage of iPhone 12 and iPhone 12Pro is the most fundamental reason. After supporting the 5G network, it consumes more power, and even the battery capacity shrinks, which is simply worse. In addition, the most direct reason for the decline of iPhone 12 battery life is the use of LPDDR4 memory, because the latest LPDDR5 memory can save 5% to 10%, and the battery life can be extended by 5% to 10%.

3. The border is too sharp and it is easy to cut your hand.

Many consumers took photos of their palms after using iPhone 12 and iPhone 12Pro online. Judging from these photos, consumers have different degrees of cuts on their palms. Slightly lighter fruit powder has obvious red marks on the palm, especially extending from the tiger's mouth to the inside of the palm, and there are also red marks on the four fingers. The most serious situation is that the finger stained with fruit powder is directly cut by iPhone 12Pro, and there is blood flow. Before the release of iPhone 12 series mobile phones, foreign media said that after the body size of iPhone 12 series mobile phones became larger, there would be hand cutting, and this prediction really came true.

4.iPhone 12 will degauss your room card and passport.

The newly released iPhone 12 series has a brand-new selling point function supporting MagSafe magnetic wireless charging. Official website shows that users can provide up to 15W wireless charging for the iPhone 12 series through the new MagSafe magnetic accessories, and when using it, they don't need to consider the location of the device. Magnetic features will make your iPhone and MagSafe charger fit together. However, some netizens who got the new machine found that the iPhone 12 mobile phone itself is relatively magnetic, which can not only attract some metal objects, such as ring needles, but also degauss some cards, even affecting some mechanical watches.

Recently, Apple released the latest support document, explaining how to use MagSafe to charge the iPhone. Among them, Apple reminded not to put items such as credit cards, passports or key chains between iPhone and MagSafe charger, which may damage its magnetic stripe or RFID chip. In order to prolong the battery life, when the battery temperature is too high, the charging may be limited to more than 80%.

According to the introduction of this official document, the magnetic charging function of MagSafe cannot avoid degaussing due to its physical characteristics. For the problem that the MagSafe charger magnet embedded in the back of iPhone 12 will degauss some cards, Kaiann Drance, vice president of Apple iPhone marketing, said in an interview that the credit card with magnetic stripe has strong magnetism, so there should be no degaussing problem. At the same time, Kaiann Drance pointed out that we should be careful of those disposable magnetic cards, such as hotel room cards. She suggested that this card can be stored in Picari of MagSafe, which is shielded. However, the price of this leather card bag is 479 yuan.
