Low-end chargers and cables without MFi certification: what are the risks for the iPhone?

Recharging an iPhone or iPad is not done with just any cable or charger. Apple has developed an MFi certification for compatible certified accessories. Let's see why it's better not to deviate from it.

MFi certification is a label set up by Apple to assure consumers that the accessory thus qualified "Made For iPhone" meets a certain set of specifications. On the manufacturer's side, this certification means more manufacturing constraints and a higher final price. But on the user side, the label reassures and even protects against the appearance of problems, especially when it comes to recharging.

Lightning cables, in particular, are available in many third-party models on the market, many are MFi certified, but others are not, attracting the user with much lower prices. But what are the risks of using a non-MFi cable? Here are some of the answers.

A component that makes a difference

In the case of a charging cable, it should be understood that MFi certification requires the manufacturer to integrate a specific component into the cable to limit voltage fluctuations at the output.

Because excessive voltage fluctuations can cause irreversible damage to the iPhone or iPad when charging. And one of the components that are most likely to suffer from these voltage variations on the iPhone or iPad is the "Tristar" chip. This is positioned on the motherboard of the iOS device. It may fry due to overvoltage. The problem, this chip is in charge of charging the battery. And once it is reached, it no longer allows the device to be recharged normally.

In addition, when the Tristar chip is damaged, the user may think of a battery problem. Except that his replacement doesn't change anything. The problem is located on the main card, it is the whole iPhone or iPad that is broken without even being repaired.

Here are the symptoms of a damaged Tristar chip, also called "U2":

  • Unable to load
  • Charging that seems to be taking place (symbol of visible charging), but the remaining percentage of battery life does not move
  • iTunes error indicating a broken connection
  • A sudden decrease in the percentage of remaining battery life in use
  • Load that is done up to a certain percentage, without going up higher
  • The autonomy that drops to a certain percentage, then the iPhone or iPad turns off

Without MFi: not without risks

If for some accessories, such as an Apple Watch bracelet, Apple certification is not of paramount importance, when it comes to charging the iOS device, whether it is the USB power adapter or the Lightning cable, we can only advise you to avoid the lower end.

To support our point, know that iFixit's specialists report thousands of testimonials from users who have broken their iPhone using a low-end non-MFi Lightning cable.

In the end, it is therefore better to invest a little more when buying a charging cable by making sure you take an MFi model, rather than risk seeing your iPhone or iPad suffer damage that could cost much more than what you would have saved by turning to a cheap cable, thinking you are getting a good deal.

Finally, it also happens that some manufacturers sell cables falsely called "Apple official". Be aware that the apple company has set up a help page to check for yourself the authenticity of an Apple Lightning cable.
