We rely heavily on our smartphones, and running out of battery can be a real hassle. That’s why fast charging has become increasingly popular among iPhone users, as it can significantly reduce the amount of time it takes to charge your iPhone, providing you with more battery life in less time.
However, it’s essential to know whether your iPhone is fast charging or not to ensure that you’re getting the most out of your device. In this article, we’ll discuss how to tell if your iPhone is fast charging and why it’s crucial to know.
1. Check if Your iPhone Supports Fast Charging
The first thing is to check whether your iPhone supports fast charging. Not all iPhone models support fast charging, and if your device is incompatible, you won’t be able to fast charge it, no matter what charger or cable you use.
iPhone 8 and all models above 8 support fast charging.
You can proceed to the next step if your iPhone model is 8 or above. If not, unfortunately, your iPhone does not support fast charging.
2. Check if You Have a Fast Charger and Cable
The next step is ensuring you have a fast charger and cable. Not all chargers and cables support fast charging, and using the wrong ones can even damage your iPhone’s battery.
To fast charge your iPhone, you must use a USB-C power adapter that supports USB Power Delivery (USB-PD) and a USB-C to Lightning cable. The USB-PD protocol allows for higher power delivery, enabling fast charging.
To identify a fast charger and cable, look for the wattage rating on the power adapter. A fast charger should have a wattage rating of at least 18W or higher. Additionally, the cable must be MFi certified, with a lightning connector on one end and a USB-C connector on the other.
If you’re unsure if your charger and cable support fast charging, check the product description or contact the manufacturer.
3. Check Battery Percentage Increase per Minute
Check the battery percentage increase per minute to tell if your iPhone is fast charging. Typically, an iPhone charging rate on a 5-watt charger is around 0.5% per minute.
However, with fast charging, your iPhone will charge 2% per minute on a 20 W fast charger. To check the battery percentage increase per minute, start charging your iPhone and note the battery percentage.
Then, check the battery percentage again after a minute or two and calculate the percentage increase per minute. If the percentage increase per minute is higher than 1.5 %, it’s a good indicator that your iPhone is fast charging.
Again, keep in mind that charging time and percentage increase can vary depending on the model of your iPhone and battery capacity. But, if you notice a significant increase in percentage per minute, it’s a good indication that your iPhone is fast charging.
4. Use an App to Measure Your Charging Speed
If you cannot identify whether your iPhone is fast charging or not with the above methods, you can use an app to measure how quickly your device is charging.
There are several apps available on the App Store that can measure your iPhone’s charging speed.
Battery Life App
One of the most popular ones is called “Battery Life.” It shows you the current charging speed and provides detailed information about your iPhone’s battery health.
Download this app and launch it on your iPhone while it’s charging. The app will display the current charging speed in milliamps (mA) and watts (W). If you see a higher charging speed than what you normally get, it’s a good indication that your iPhone is fast charging.
Ampere Battery Charging Check App
Another app is Ampere, which measures how quickly your iPhone charges in real time. This app also gives you detailed information about your device’s current and maximum power draw while it’s charging.
These apps can help you determine if your iPhone is fast charging or not without having to rely on guesswork.
Conclusion
In conclusion, first, check your iPhone model, as not all models support fast charging. Then, ensure you are using the right charger and cable supporting USB Power Delivery (USB-PD). Thirdly, measure the battery percentage increase per minute and compare it to the normal charging rate.
Finally, you can use an app to measure how quickly your iPhone charges and get detailed information about its battery health. These steps will help you determine if your iPhone is fast charging.
