The iPhone 16 comes with a powerful battery, but charging it can take up to four hours if you use a slow charger.
However, with the right accessories, you can fast charge your iPhone 16 from 0% to 50% in just 30 minutes and reach a full charge in about two hours.
Why is your iPhone 16 charging slowly?
If your iPhone 16 is taking too long to charge, you might be using a slow charger. iOS 18 now alerts users when they are charging at slow speeds. By checking Settings > Battery, you can see an orange warning text if slow charging is detected. Using the right charging accessories can significantly cut down charging time.
How to fast charge iPhone 16 using USB-C
The iPhone 16 supports fast charging up to 27 watts through its USB-C port. To take full advantage of this, you need a USB-C cable and a power brick of at least 30 watts. Recommended options include:
- Apple’s 35-watt dual charger
- Mophie’s compact 30-watt charger
With a 30-watt charger, your iPhone 16 can charge 50% in 30 minutes and 100% in around two hours. If you only have a 20-watt charger, the charge time increases slightly, but it still offers a fast charging experience.
How to fast charge iPhone 16 wirelessly using MagSafe
The iPhone 16 series introduces faster wireless charging with MagSafe. With a 30-watt power adapter, the latest MagSafe chargers can deliver up to 25 watts of power. This means your iPhone 16 can wirelessly charge to 50% in about 30 minutes and reach full charge in around two hours.
While wireless charging is slightly less efficient due to heat buildup, it is now almost as fast as wired charging for the first time.
