How to Know if Your iPhone is Fast Charging


Fast charging has become a popular feature in the world of smartphones. With our busy lives, we often need our devices to charge quickly and efficiently. Apple’s iPhones now support fast charging, assuring users can get their phone back up and running in no time. But how can you tell if your iPhone is actually fast charging? In this article, we’ll discuss ways to determine if your iPhone is taking advantage of its fast charging capabilities.

Identifying Fast Charging-Compatible iPhone Models:

The first step to understanding if your iPhone is fast charging lies in knowing which models support this feature. The following iPhones are compatible with fast charging:

1. iPhone 8 and iPhone 8 Plus

2. iPhone X, XR, XS, and XS Max

3. iPhone 11, 11 Pro, and 11 Pro Max

4. iPhone SE (2nd generation)

5. iPhone 12, 12 Mini, 12 Pro, and 12 Pro Max

6. iPhone 13, 13 Mini, 13 Pro, and 13 Pro Max

The Requirements for Fast Charging:

To enable fast charging on your compatible iPhone, you’ll need the right accessories. You’ll require a USB-C to Lightning cable and a power adapter that supports Power Delivery (PD) technology. A PD-supported charger has at least an 18W output.

Checking for Fast Charging – Initial Tactic:

While Apple does not offer a direct indicator for fast charging on your screen when you plug in your device, there is an audible clue that can help you identify a fast charge. When using a compatible charger and cable setup, connecting your device should emit the familiar charging chime twice in quick succession. This double-chime indicates that the phone recognizes the fast-charging connection.

Monitoring Charge Speeds with an App:

Another way to determine if your phone is fast charging involves the use of a third-party app. Several apps, such as Ampere or CoconutBattery, can provide detailed information on your iPhone’s battery and charging rates. By monitoring these rates, you can compare them to fast-charging benchmarks to determine if your device is charging at optimal speeds.


Fast charging has become a crucial feature for many iPhone users. Knowing whether your device is taking full advantage of this time-saving technology is essential. By following the steps outlined in this article, you can be sure that your fast-charging-compatible iPhone is operating at maximum efficiency, allowing you to stay connected with minimal downtime.
