Read the article to the very end to learn about all these crucial aspects of getting rid of this annoying issue.

Part 1. What Does It Mean When iPhone Says, “This Accessory Uses Too Much Power”?

The “This accessory uses too much power” message on your iPhone means that the connected accessory is drawing more electrical current, violating the safety of your mobile. In particular, accessories like external drives and certain headphones often require more energy to function correctly. So, the iPhone tries to protect its internal components from overloading damage by warning you with this message.

Moreover, you can also expect this troublesome notification when you use non-certified accessories if they are defective. Additionally, those with faulty mobile charging ports can also experience this problem. Thus, it’s crucial to understand the root cause of this “cannot use accessory” message and take appropriate actions to avoid potential damage to your iPhone.

Part 2. How to Fix Can Not Use Accessory on iPhone and iPad

Now that you get the in-depth context of this frustrating iPhone notification, let’s move on to the section explaining how to fix it. Fortunately, there are several troubleshooting techniques you can apply to find the root causes and pull them out effectively. This section will cover some common scenarios and provide suitable solutions to help you get your accessories working seamlessly.

Situation 1. Your iPhone Thinks the Charger is An Accessory

One common scenario in which the “iPhone cannot use accessory” problem occurs is when your smartphone mistakenly identifies your charger as an accessory. It can probably happen if you use an unofficial adaptor or power cable to charge your mobile.

This problem is particularly relevant for users of the iPhone 15 Pro, who may be experiencing it more frequently due to the device’s advanced power management system. Now, let’s talk about the solutions for this trouble in the following section:

1. Use Official Apple Accessories

Apple-certified chargers and cables meet strict safety and efficiency standards, which help prevent issues like the “Cannot Use Accessory” message. So, using official Apple accessories is crucial for ensuring compatibility and optimal performance with your iPhone 15 Pro. Make sure to look for the official label on the packaging of third-party accessories, which indicates the certification of the product.

2. Inspect the Cable and Adaptor

Faulty or damaged cables and adapters can cause your iPhone to misidentify the charger as an accessory. That’s why you must regularly check these components for any signs of wear and tear that may cause trouble. Here, look closely at both ends of the cable for any bent connectors or exposed wires. Also, check the iPhone adapter for any cracks or other visible damage, as a faulty adaptor might not provide a stable power supply.

3. Clean the Charging Port

Undoubtedly, debris in the charging port can interfere, preventing your iPhone from connecting to the charger. Even tiny particles of dust can cause significant issues, leading to the “This accessory uses too much power” issue. So, power off your iPhone 15 Pro and gently remove any dust and debris particles from the charging port. However, be careful about inserting anything that could damage its internal components.

Situation 2. iPhone Alert Keeps Showing “This accessory requires too much power”

The previous situation was all about the charger-related issues that led to the “this accessory requires too much power fix” issue. Now, let’s ponder over the other situation where the iPhone alert remains consistent with this problem even after resolving the charger and the port factor. In this regard, it would be better to first understand the potential causes of this troublesome scenario:

Beta iOS Update: Sometimes, upgrading to a new beta iOS version can introduce compatibility issues with accessories that previously worked fine. Here, the latest updates may have new power management protocols that certain accessories are not compatible with.
Accessory Power Demand: External hard drives or certain types of speakers, require more power than the iPhone can provide through a standard connection. So, if you have connected any of these, there’s a slight possibility of these factors being the cause of this situation.
Non-Certified Accessory: Another aspect can be the use of non-certified or third-party accessories, which can lead to compatibility issues. The reason for this phenomenon is that these unofficial products do not meet Apple’s power specifications.

After having a better grasp of these reasons, let’s take this topic to the next step, where we will enlist some further solutions to fix the “cannot use accessory issue.”
