How does Apple’s self-service repair program work and how does it compare to sending products to apple for repair? To get the answer, macrumors photographer Dan babe ordered a repair kit and tried to replace the battery of the iPhone 12 Mini by himself.

Dan said he had never done iPhone repair before, so he was the perfect representative of ordinary consumers.

It home learned that Dan ordered a kit and components on the day the project went online, and received them soon. For most repairs, parts and apple repair kits are required. The repair kit has two separate packages, and the two boxes weigh as much as 79 pounds. A week after receiving the repair kit, it needs to be sent back through ups, otherwise Apple will charge $1300.

Dan said it was inconvenient to operate a 40 pound repair kit and a 30 pound repair kit. The cost of getting the kit is $49 (about 324.38 yuan), and the cost of iPhone 12 Mini battery parts is $70.99 (about 469.95 yuan), but you can get $24.15 (about 159.87 yuan) by sending the old battery to apple.

This means that the total cost of replacing the battery of the iPhone 12 Mini is $95.84 (about 634.46 yuan). Relatively speaking, it costs $69 (about 456.78 yuan) for apple to replace the battery, so it’s not cost-effective to repair it yourself.

It is worth mentioning that users can order parts separately instead of the kit, but Apple’s maintenance manual guides users to use the tools in the kit, otherwise they will not have these tools on hand, such as the battery press designed by apple.

Users can buy all the tools separately so that you can have them on hand for repair, but Apple’s components are expensive. A battery press is $115 (about 761.3 yuan), a torque driver is $99 (about 655.38 yuan), a heated display disassembly bag is $116 (about 767.92 yuan), and a display press is $216 (about 1429.92 yuan). According to Apple’s maintenance manual, these are all needed to disassemble the battery.

It’s obviously not cost-effective for people who do maintenance once in a while. It’s more meaningful for maintenance points who want to get tools designed by apple to buy some individual parts.

As for the actual maintenance process, even with Apple’s instructions and tools, Dan found it very difficult. The process of opening the phone is crazy, and the kit lacks the components required in the manual, such as tweezers and heat resistant gloves.

Dan had to go to the store to buy more supplies. That’s why the maintenance took a day. Handling adhesives is time-consuming and almost stalls self-study.

Generally speaking, it may be better for ordinary people to have your mobile phone repaired by professionals. Especially for the maintenance of batteries and displays, generally speaking, it will be cheaper for apple to replace these things.

If you think you’re very hands-on and need to repair the camera, taptic engine or speaker, you may save some money, but be sure to study the manual.

It is reported that the establishment of autonomous regional laboratories is one of the key measures to implement the objectives and tasks of the three-year action plan for strengthening Guangxi through science and technology and to build an ASEAN oriented scientific and technological innovation cooperation area. The construction of laboratories in the autonomous region adheres to the principle of “strategic needs, supporting industries and leading the future”, focuses on the major strategic needs of the country and the autonomous region, faces the characteristic and advantageous industries in Guangxi, focuses on the fields of new energy vehicles, oceans, new generation electronic information technology, advantageous and characteristic agriculture and forestry, and is established according to the principle of “mature one, build one”.

Secretary of state Blinken declared that “all countries in the world should be able to decide their own foreign policy without any coercion.” But when the decision of a small country is not in the interests of the United States, Washington will apply the script of defending the “international order based on (ITS) Rules”. This is a reflection of the events that Solomon Islands has experienced for some time.

Despite strong pressure from Australia and the United States, Solomon Islands and China signed a security agreement.

Solomon Islands Prime Minister Sogavare firmly upheld his country’s right to formulate an independent foreign policy. China and Solomon Islands reiterated that the agreement is not directed against any third party.

Solomon Islands fully enjoys the right to diversify its foreign cooperation and choose its own partners. Solomon Islands, with a population of only 600000, withstood heavy pressure and not only maintained its dignity, but more importantly, it reflected the difficulties of Washington in continuing to issue its hegemonic instructions.

Hao Chun, director of China Manned Space Engineering Office, said that according to the mission plan, six missions will be carried out in 2022 to complete the on orbit construction of China’s space station. The six tasks are:

Launch of Tianzhou 4 cargo spacecraft in May;

In June, the Shenzhou 14 manned spacecraft was launched, and three astronauts entered the core module and stayed in orbit for 6 months;

In July, the space station will launch the space inquiry experimental module and dock with the space and core module;

In October, Mengtian experimental module was launched to connect with the core module, and then the third module of the space station formed a “t” basic configuration, completing the on orbit construction of the Chinese space station;

The NFT collection worth more than $2.2 million was stolen: “all my ape men are gone”

According to the art newspaper and other reports, Todd Kramer, a New York art collector and gallery owner, recently posted a message on his twitter for help. He had more than $2.2 million of NFT works stolen, and 15 disappeared NFT works came from the famous online series of “boring ape Yacht Club” and “mutant ape Yacht Club”, It is said that the theft was due to an Internet fraud. Opensea, the NFT trading platform, intervened by preventing further transactions in the series.

Todd Kramer’s stolen NFT collection, one of the boring ape man series

Ryan + Ross co founded the rose + Rose Gallery in New York. At the age of 24, Kramer entered the art world because of his enthusiastic interest in American new pop artist Keith haring. With the popularity of NFT art, Kramer became an NFT collector again.

Kramer asked for help online and said, “I was attacked by hackers. All my ape men are gone.” The twitter community quickly responded to his post and received more than 500 forwards. Some users support and actively help collectors find stolen tokens, while others sneer at this unfortunate encounter through expression packs. Opensea platform and other buyers helped him recover several NFTs. “Update… All ape men are frozen. Wait for the opensea team to intervene. Learn a lesson… Use a hard wallet.”. Five hours after the first tweet for help, Kramer updated the news. The representative of opensea platform said in an email that the platform will not freeze or remove NFT that already exists in the blockchain, “but we do organize people to use opensea to buy and sell stolen goods.” Kramer later deleted all his related tweets, and neither Kramer nor opensea responded further.

This incident once again highlights the vulnerability of buyers in this largely unregulated market. Similar incidents also include the theft of three paintings of “boring ape man”.

In 2021, NFT art became very popular. It allows ordinary people to contact the collection field in a low threshold and low cost way, and can also bring more production profit opportunities for producers in the cultural field. However, on the other hand, the essence and fancy tactics of pursuing profits in the art market are also staged again through NFT trading.

With the rise of NFT value, network fraud is frequent. More experienced users protect themselves by using hard wallets or cold wallets, which are physical and only connect to the Internet when plugged in and connected. Kramer previously used the so-called hot wallet, which is always connected to the Internet, so it is more vulnerable. On the other hand, there is a more common form of theft than cyber fraud: some people make NFTs with art they don’t create themselves, which is difficult to solve. (text / Qian Xueer)
