iPhone displays 'Accessory not supported' when charging: causes and solutions

If your iPhone, from the iPhone X to the latest iPhone 17 Pro Max, displays the "Accessory not supported" message while charging, you know how frustrating this issue can be. This message prevents the phone from charging normally and can appear at any time, leaving the user without access to the energy needed to use the device.

At iServices, we understand the importance of efficient and safe charging for your iPhone. This article explains the most common causes of this problem, presents practical and detailed solutions, and shows how we can help with professional technical support in any of our 76 stores in Portugal.

Why does the iPhone say 'Accessory not supported' while charging?

Non-certified or damaged cable or charger

One of the most common reasons why the iPhone indicates that the accessory is not supported is the use of cables or chargers that do not meet Apple standards. Counterfeit, poorly produced cables, or cables with visible damage can cause this message. Furthermore, the charger may have internal defects that affect communication with the phone.

Dirty or damaged Lightning port

The iPhone charging port collects dust, lint, or moisture, which can prevent a proper connection with the cable. If the port is damaged, due to impact or wear, the device may reject the accessory as a protective measure.

Software error on the iPhone

Sometimes the problem lies in the iOS operating system, which can exhibit temporary errors or bugs that affect the recognition of accessories. Incomplete or failed updates can likewise cause this message.

Internal hardware problems

Internal components related to the charging circuit may be damaged, such as the Lightning connector on the motherboard or other elements that regulate the power supply. In these cases, the iPhone may no longer be able to recognize legitimate accessories.
