How to charge phones faster on laptop

To charge a mobile phone, it is advised to use a charger box and connect it to a wall socket. This ensures the highest charging speed if the charger is in good condition.  

But sometimes, for convenience, or because we have more tasks at hand or limited outlets, we charge our mobile phone by connecting it to a computer’s USB port. This is perfectly valid and there is no problem in doing so. But on a modern PC, there are USB 2.0 and 3.0 ports, so it is normal to ask: In which USB port will my phone charge faster?

The type of USB port influences the maximum recharge speed. A  USB 2.0 port can supply up to 500 mA, while a USB 3.0 port offers up to 900 mA. But that does not mean that all phones connected to a USB 3.0 will charge faster than a USB 2.0 port. Of course, there are other factors involved.

Specifications of USB port

The other specifications are as follows.

The maximum capacity of the battery:

If the battery only accepts up to 500 mA, then there will be no difference between using a USB 2.0 or 3.0 port.

The software

There are smartphones that, based on compatibility, can limit the load to 500 mA when they detect that you have connected it to a USB port, although that port offers more charge power. More modern versions of operating systems disable this limitation when they detect that the port is USB 3.0 or higher.


Not all USB cables are the same. If the mobile accepts the charging at 900 mA and connects it to a USB 3.0 port with a USB 2.0 cable, it will only recharge at 500 mA.

In summary, if you want to charge your phone at maximum speed on a PC, you’ll want a USB 3.0 port and also a USB 3.0 cable. Be sure to check that both the battery and the operating system allow fast charging through a USB port, not just from a charging box.

This is how we can charge our phone faster from our PC or laptop. When you are in a hurry, it is quite helpful to do so. Check out the power of your ports—look up which ports your laptop or your computer system has. Then, plug in the necessary USB cables to the port.
