Why is this accessory not supported in Apple iPhone tips

Apple launched three iPhone 11 / 11 Pro models on September 11, which are popular in China. Some Apple iPhone users will prompt "this accessory is not supported" or "this cable or accessory has not been certified, so it may not work reliably with this iPhone" when charging the device, resulting in the problem of unable to charge. What's the reason Apple iPhone does not support this accessory? What causes "this cable or accessory is not certified and may not work reliably with this iPhone"? Come and have a look.

"This accessory is not supported" or "this cable or accessory has not been certified, so it may not work reliably with this iPhone" is only due to the use of a fake lightning cable or charger? Not really. There are many reasons for this problem. Let's analyze it together.

Reason 1: the apple data line used is not MFI certified.

Apple has launched MFI certification for aligning peripheral accessories. The data line or accessories without certification can not be well recognized by Apple devices. At this time, it is recommended to replace Apple data line products with MFI certification. Green link iPhone data cable, certified by Apple MFI, is compatible with all IOS systems.

Reason 2: if the product has passed the MFI certification, or even the original iPhone data line of apple, there are such prompts, which are recommended to be excluded from the following aspects:

1. Insufficient power supply

A. This happens when you connect your iPhone or iPad to the USB 2.0 interface of your computer. As we all know, the maximum output current of USB2.0 interface is only 0.5A, mostly lower than 0.5A. The low current, which does not reach the nominal current for iPhone / iPad charging, has led to a warning from Apple's device's power management system. Try to use the charging head to charge the iPhone, or connect the USB 3.0 interface of the computer

B. The use of poor quality non-standard charging head often leads to insufficient output power (lower than 5v1a). There will also be a prompt that such accessories are not certified. The problem can be improved by changing the original charging head or the charging head with good quality (knowing about the green USB charger).

2. The lightning charging interface of iPhone / iPad is polluted, resulting in poor contact

If the charging interface, or the gold finger of the MFI certified connector is contaminated or dusty, resulting in poor contact, there will also be an uncertified prompt, which is often seen in the black position of the fourth contact (not dirty but oxidized). In this case, cleaning and scrubbing the golden fingers to make the charging port better contact with the iPhone data cable can effectively solve this problem.

3. Data line is damaged

This can also happen with a damaged iPhone cable. At this time, you can only replace the iPhone data cable with a new one.

These are the reasons why the iPhone product prompts "this accessory is not supported" or "this cable or accessory is not certified, so it may not work reliably with this iPhone". Through the above methods, we can solve this problem.
