How to Know if Your iPhone is Fast Charging


Fast charging has become a must-have feature for many smartphone users, especially those who need a quick boost of battery life during their busy daily routine. iPhone users can also benefit from this incredible technology. In this article, we’ll guide you on how to know if your iPhone is fast charging.

1. Make Sure Your iPhone Model Supports Fast Charging

First and foremost, check if your iPhone model supports fast charging. Apple introduced the fast charging feature in its iPhone lineup starting with the iPhone 8, 8 Plus, and X models. All subsequent iPhones, including the iPhone XR, XS, XS Max, SE (2nd Gen), 11, 11 Pro, 11 Pro Max, 12 Mini, 12, 12 Pro, and 12 Pro Max can enjoy fast charging as well.

2. Use a Compatible Charger and Cable

To enable fast charging on your iPhone, you’ll need to use a compatible charger and cable that supports USB-C to Lightning charging. Apple’s official chargers rated at either 18W or higher provide the fastest charging experience; however, some third-party chargers may also support fast charging as long as they adhere to the recommended power specifications.

3. Check Fast Charging Status Indicators

There’s no direct way or notification to show you that your iPhone is fast charging. However, you can estimate how quickly your device is charging through some indirect indicators:

A) Battery Percentage Indicator: Observe the battery percentage during the first few minutes of plugging in your device for fast charging. If it goes up by around 1% per minute or higher consistently during the first few minutes (when battery percentage is below ~80%), it’s an indication of efficient fast charging.

B) Estimated Time Until Full: Another method to gauge if your device is fast-charging is by looking at the estimated time until full (ETUF), which appears on the lock screen after plugging in your phone. Typically, a device using fast charging would show an ETUF of around 1 hour or lower.

C) Temperature: Fast charging usually comes with increased temperature. If you notice that your iPhone is slightly warming up during the charging process, it might be a sign of fast charging.


In summary, to know if your iPhone is fast charging, make sure your device supports the feature, use a compatible charger and cable, and check for indirect indicators such as battery percentage increase rate, estimated time until full, and device temperature. Always remember to use official or certified cables and chargers to ensure a safe and optimal charging experience.
