One of the features that Android users like to boast about to their iPhone-toting friends is "quick charging," and it's certainly a boast-worthy trait.
As you might have guessed from its name, the quick charging feature is, indeed, quick. There are several YouTube videos and articles showcasing how much faster an Android phone like the Galaxy S8 can charge versus the iPhone 7. In one video, an iPhone 7 Plus took an entire hour longer to charge from zero to 100% than a Galaxy S8+.
So, quick charging is a worthwhile feature. It means you can get more charge in less charging time, which is incredibly meaningful for a device that's always turned on and that's used on a regular basis.
Check out how and why some Android phones can charge so much faster than iPhones:
You might see the words "Quick Charge" or some other variation in an Android phone's marketing material or inscribed on its charger.
"Quick Charge" is a technology that was developed by chip maker Qualcomm, which the company adds to certain models of its chips.
Qualcomm's Quick Charge tech is different from regular charging in that it uses a different combination of voltage and amps to provide a higher wattage – and therefore faster charging.
Whereas the iPhone's regular charger outputs 5 volts at 1 amp for a total of 5 amps, a Quick Charger can output 9 volts at 1.67 amps, making for 15 amps. Some quick chargers even go up to 12 volts at 1.67 amps, making for a fast 20 watts that's incredibly fast for a mobile device.
Where Qualcomm's chips come into the equation is the management of that charge to keep within a battery's safety threshold.
And a lot of Android smartphone makers use Qualcomm chips in their phones, so they can benefit from Qualcomm's Quick Charge technology.
