At times, when you plug your iPhone to a Lightning charger cable, a pop-up will appear on the screen saying This cable or accessory is not certified and may not work reliably with this iPhone. Before blaming the poor quality of the accessory or looking down at your MFi certified cable or throwing it away in a fit of anger, you should try out a few tricks to shoot away the error instantly.

There are three main reasons why “Accessory Not Certified” warning crops up:

Accessory Is Not Certified Issue on iPhone and iPad

Cable Is Not Certified/Poor Quality

There are tons of Lightning cables available at a comparatively low. Despite being not MFi (Made for iDevice) certified, they worked well and sold like hot cakes. The best thing about them is that you don't have to pay a heavy amount to buy them. And, the bad thing is they are worn out sooner than later.

Damaged Cable

How about those Apple-certified cables? I have encountered this issue even with the MFi certified cables.

If your charging cable has been submerged in water or got damaged due to repeated use or is corroded, it won't work.

Something is preventing the cable charger or port

If there is pocket lint or crud in the lightning port, it will obstruct charging. Hence make sure to clean up the port frequently.

Though it's less likely, you should ensure the dirt doesn't come in the way of charging.
