Fastest Charging Phones of 2021: Charging Speeds Compared

Share

When you’re shopping for a new phone, one of the often overlooked specs you should be considering is the phone’s charging speed or how long it takes for the phone to fully charge. 

Although it’s typically true that the bigger the battery, the slower the charge, calculating a phone’s charging speed actually depends on many factors: the phone’s battery capacity (which is measured in milliamp hours or mAh), the phone’s maximum supported charging speed (measured in watts) and the power of the charger you’re using (also measured in watts).

So what’s the fastest charging phone? You may be surprised to know that at the time this blog is being written, it’s not the latest iPhone or Samsung Galaxy but rather it’s China’s OnePlus 9 and 9 Pro that are the fastest charging phones in the world!
