Why is Your iPhone Charging Slowly?

Let’s explore some common reasons why your iPhone may be charging slowly.

  • Faulty cable and adapter: If your charging cable is frayed, bent, or damaged, and your adapter isn’t MFi-certified, it could slow the charging process.
  • Damaged charging port: If there is dust inside the charging port or liquid damage, that could obstruct the cable pins and lead to your iPhone charging slowly.
  • Battery health: If your iPhone’s battery health has deteriorated significantly, it may charge slowly.

These are some of the main reasons your iPhone may be charging slow. Now, let’s look at five tips to boost your iPhone charging speed.

5 Tips to Make Your iPhone Charge Faster

Although you can’t make many customizations in an iPhone, there are some tweaks you can implement to lower the time it takes for your iPhone to charge. Here are five tips.

1. Update iOS and Restart Your iPhone

There may be some temporary bugs that are making your iPhone charge slow. Updating iOS and restarting your iPhone can remove these bugs.

To check updates for your iPhone, open Settings, go to General, and Software Update. If an update is available, tap Download and Install.

2. Minimize Background Activity

Sometimes, certain apps running in the background can consume power and slow the charging process. To quit these apps, swipe up from the bottom of the screen or double-click your Home button, and then swipe up on the app previews.

3. Disable Clean Energy Charging (US Only)

Clean Energy Charging (CEC) is a feature that selectively charges your iPhone when lower carbon-emission electricity is available. It may be good for the environment, but it can lengthen the charging time based on when you plug in your iPhone.

To deactivate CEC, open Settings, go to Battery, Battery Health & Charging, and toggle off Clean Energy Charging. On the same page, you can also toggle off Optimized Battery Charging.

4. Enable Low Power Mode

One way to speed up charging is to ensure your iPhone consumes less energy when plugged in. For this reason, avoiding using your iPhone while charging is often recommended.

You can enable Low Power Mode (LPM) to save energy further. Open Settings, go to Battery, and toggle on Low Power Mode. In addition, you can also enable Airplane mode.

5. Use a Fast Charger

You can add over 50 percent battery in around 30 minutes using a fast charger! Besides a third-party fast charger, you can also use the high-watt adapter (above 20W) that came with your iPad or MacBook to fast-charge your iPhone. Check this support page to learn more.

What’s Next?

If implementing the above solutions didn’t improve your iPhone charging speed, I recommend you contact Apple Support. You can take your iPhone, charging cable, and adapter to an authorized service provider for a diagnosis and receive further guidance.


Here are some common questions about iPhone charging slowly.

Can Using a Wireless Charger Slow Down the Charging Speed of Your iPhone?

Yes. Wireless charging is convenient, but it’s not as fast as wired charging and produces more heat. Wired charging is optimal for charging your iPhone as quickly as possible.

Should You Worry About Overheating When Charging Your iPhone?

No, it’s normal for your iPhone to be warm when charging, but not to an extreme degree. If it’s going above 95ºF or 35ºC when charging, take steps to regulate the temperature, like putting it in a cooler environment and increasing airflow.

Is It Possible for a Virus to Affect the Charging Speed of Your iPhone?

Yes, especially if your iPhone is jailbroken. A virus can consume extra resources, slowing down the charging speed. You can install an antivirus on your iPhone and update iOS to remove viruses.


If your iPhone is charging slowly, it’s essential to consider the cable and adapter quality, charging port, and battery health. To optimize the charging speed of your iPhone, update iOS and restart it, minimize background activity, disable CEC, enable LPM, and use a fast charger.
