Fix the “Accessory Not Certified” issue on iPhone/iPad

When you plug your iPhone into a lightning cable to charge your device, you suddenly see a pop-up appearing on the screen, “This cable or accessory is not certified and may not work reliably with this iPhone. “
You have tried to plug out then plug in again many times but it still does not work. Before throwing it away, you should try out a few tips to fix the issue.

Reasons cause “Accessory Not Certified” issue:

Cable is not certified/poor quality

There are tons of available lightning cables with a low quality. Although they work well, almost of them are not certificated MFi (made for iDevice). The best thing about them is that you do not have to pay much money to buy them. However, the bad thing is that they will be broken sooner than MFi cables.

Damaged cable

If your charging cable has been submerged in water or was damaged due to repeated use, it will not work.

Something prevents the cable charger or port

If the lightning port is dirty with crud, for example, it will obstruct charging, so you should clean up the port frequently.
