The new iPhone is about to be released in September. Is it possible that friends around the world have stolen the phone, broken the screen, shaken the camera, slowed charging, and the battery is not durable?

However, these reasons for changing a new phone are too general. If you want to change a new phone, I can provide a new idea here, you can try using a cottage line to charge the phone.

Recently, a friend used a cottage data to charge his mobile phone charging IC chip first. This is the real master operation.

The warrior didn't care when he bought the data cable. He just bought a data cable and used it. After charging and exploding the mobile phone chip, he spent 150 repairs at his own expense.

To say that mobile phones are still very delicate electronic devices, if I have not personally experienced such a bloody lesson, I would not believe that a data cable can charge a mobile phone.

However, to say that IC chip charging and explosion is completely a wire pot, I don't believe it, but Apple's after-sales rule is that using a third-party product to cause damage to the device is not a warranty. Therefore, you need to pay attention when choosing a charging data cable for your mobile phone.

This time my friend's is a delicate Apple phone filled with IC chips by a data cable. This time, I will use an Apple phone as an example to help you answer how to choose a mobile phone data cable.

First, let's talk about the importance of the data cable of the Apple mobile phone. In the data cable of the Apple mobile phone, there are multiple chips cooperating. Cables and some non-MFi data cables do not have such a function, and it is easy to cause damage to the device during charging.

Too long to see the version

1. First of all, Apple mobile phone users recommend using an MFi-certified data cable, which is a prerequisite for safe charging of Apple mobile phones. (Not to say that non-MFi certified cables cannot be used, but it is more secure to use MFi certification)

2. In terms of material selection, the cable is selected to compile the data cable of the cable, and the durability of the outer cover is better.

3. Pay attention to the material at the interface. Basically, the contacts at the USB interface of the data cable that has passed the MFi certification are gold-plated. The contact effect and the life of the contacts can be well guaranteed.

4. If there is a PD protocol, it is recommended to use the PD protocol, 50% fast charging for 30 minutes is quite cool.

Why MFi certification

Let's first understand what MFi certification is. MFi is not just a MFi certification chip added to the data line, but a certification that the data line complies with the standard.

MFi is a license mark produced by Apple to parts manufacturers. Apple accessories that have passed MFi certification have certain restrictions on the quality of their components and production processes. Therefore, MFi certification for Apple is a limitation on the quality control of accessory manufacturers to ensure that accessory manufacturers produce products that meet their own standards.

MFi-certified Lightning data cables, Apple will provide MFi-certified chips, which can ensure that the data cable can still be used normally after the equipment system is upgraded.

Non-MFi certified data cables may cause the device to fail to recognize the iPhone or iPad after the system upgrade, and some charging functions may not be supported.

In addition, the chip provided by Apple can ensure stable output during charging, which is a protection for the device itself. In addition, Apple's warranty policy does not support damage caused by using non-MFi certified accessories. Accessories without MFi certification are like wild children in the Apple system. same.

This makes the products with MFi certification have a higher gold content. Under the promotion of these years, the recognition and recognition are now very high, and the MFi logo and logo are usually printed on the outer packaging.

MFi-certified wires have functions such as temperature protection, static protection, over-voltage protection, and over-current protection. Non-MFi-certified wires are largely free of these protections.

At the same time, certification fees can also be charged, so products certified by MFi are usually sold at higher prices. MFi-certified Lightning data cables, Apple will provide MFi-certified chips, which can ensure that the data cable can still be used normally after the equipment system is upgraded.

Non-MFi certified data cables may cause the device to fail to recognize the iPhone or iPad after the system upgrade, and some charging functions may not be supported. In addition, the chip provided by Apple can ensure stable output during charging, which is a protection for the device itself.

MFi certification is quite difficult and requires high qualifications from manufacturers

According to the information we have learned before, the MFi certification pass rate is not high, and the application cost and qualification requirements are not low.

First, the MFi certification application has two certification tests, which are AGS and OTA certification, respectively. Manufacturers need to submit fees of about $ 580 and about $ 1,500, but these are small money.

The harder part is the qualification review. If you want to apply, you must have your own factory, and the factory also needs to have a certain scale. Not any individual or a manufacturer has the qualifications to apply. This will eliminate some small factories Or a small brand with some foundries.

And in the application process, it is necessary to repeatedly modify the product design until all parameters reach Apple's standards, and the entire process will take up to 3 to 5 months. At the same time, please note that there are restrictions on the number of times a brand can apply for MFi certification! That is to say, even if manufacturers want to send money to Apple, Apple will not necessarily pick it up.

What if you want to know if the data cable you bought is MFi certified and there is no MFi detector nearby? Apple has an official MFi certification inquiry website, which supports querying MFi certification through product barcodes.

Data cable material comparison is recommended to buy braided wire

At present, the material of the outer cover of the mobile phone data cable is mainly divided into PVC, TPE and nylon braiding (now most of the data cables are braided). When electronic products were just emerging in the early years, the data charging cable was basically made of PVC. Low cost processing technology is its advantage. At present, some data lines are still made of PVC material.

However, because a large amount of additives will be added during the processing, many cheap data lines use cheap and unqualified PVC materials, which is also the source of the pungent odor of this part of the data lines.

Compared with PVC, TPE material will be much safer, and the finished product of the wire is soft and easy to mix and match with various colors and has been favored by most manufacturers. Apple ’s own accessory products are basically made of TPE.

However, we should note that the TPE material will easily oxidize and yellow, especially Apple's own accessories, and it is also particularly fragile. The interface tail wire and the wire interface are particularly vulnerable to "peeling."

The third category is nylon braided wire. The advantages of nylon braided wire are wear resistance and resistance to pulling. However, the nylon wire that came out earlier is hard and easy to fluff, and everyone dislikes it.

But after that, many large factories began to apply new nylon braided materials to the data lines. The new nylon braided materials will be softer. If the manufacturer requires a higher level, the braided wire materials will basically have no fluff during the use.

Regarding the outer cover of the wire, I still recommend that you try to choose TPE or nylon woven outer cover. Even if you choose PVC material, you should choose the wire of a qualified manufacturer as much as possible. After all, you do n’t know the outer cover material of Taobao 9.9 It is the "first hand".

Interface selection considerations

The interface part is actually very small details.

At present, some data cables on the market will gold-plat the contacts. Gold plating of the contacts will enhance the conductivity and the oxidation resistance of the contacts, improve the stability of charging and data transmission, and also increase the life of the data cables.

When MFi certification is also required, the USB contacts must be gold-plated (from "Identifying Counterfeit or Uncertified Lightning Connector Accessories" issued by Apple's official website on 2018.05.09).

In addition to the contacts, you also need to pay attention to the material of the package on the interface. There are very data cables that only perform conventional anti-corrosion and anti-rust treatment on the interface. Although the anti-corrosion effect can be achieved for a period of time, it will last for a long time. With the increase of the thickness, the special treatment layer will peel off, and the exposed tinplate will still cause rust problems.

Therefore, it is recommended to use 304 or other data cables with corrosion-resistant and oxidation-resistant interfaces.

Data cable core material

If the wire is disassembled, you can find that the wire material is different for different price data.

Although it is not common for data cables to burn and catch fire, it is not without related news reports.

Of course, it is impossible for us general consumers to buy a data cable to verify whether the shielding layer is wrapped and whether it has flame retardant properties. At this time, we need to choose a data cable produced by a qualified large manufacturer as much as possible, even if there are no special attributes. There will be no danger or defect.
