What is fast charging and how does it work?

With fast charging, your phone charges a lot faster than normal. Handy if you just want to leave and notice that your phone is almost empty; after a short charge you can last a few hours. Here, we'll explain what fast charging is and what you need for it.

How does fast charging work?

Quick charge Moto G6

When fast charging, your phone transfers a higher amperage through the cable. If your phone normally gains 5 watts of power from charging and 18 watts when fast charging, it means you can fully charge the battery twice as fast. As your battery gets fuller, charging becomes slower to prevent your battery from breaking. As a result, fast charging is mainly suitable if you want to charge an empty battery fast so you'll have enough power for a few more hours.

What do I need to fast charge my phone?

Not all chargers are fast chargers, and not all phones support fast charging. In order to use fast charging, you'll need both a charger and a phone featuring a fast charging function. If your charger isn't equipped with a fast charging function, you can't use it to fast charge your phone. If you do have a fast charger, but your phone doesn't have a fast charging function, your smartphone will be charged at normal speed. Do you often charge your phone using a power bank? There are power banks with a fast charging function, which means this will go extra fast.

Is fast charging bad for my battery?

Quick charge Samsung Galaxy S9

Fast charging is no worse than normal charging. Your phone does not get more energy than it can take. It also gives no problems if you use a quick charger for a phone without fast charging, or just a normal charger for your phone with fast charge function. Your phone will charge at normal speed.
