How To Make Laptop Charge Phone Faster? 6 Ways

Laptops can do much more than we need them to. In addition to all the tasks a laptop computer should ordinarily do, they can charge mobile phones, but with a catch.

It’s common knowledge that laptops charge phones significantly slower than most regular chargers. While charging through USB ports on your laptop may not be as fast as using a wall socket, it shouldn’t be extremely slow unless something is wrong.

In this article, you’ll learn why your laptop charges your phone slowly and how to make your laptop charge your phone faster.

What Causes My Laptop To Charge My Phone’s Battery So Slowly?

The problem is usually a faulty cable. USB cables typically deteriorate over their lifespan, charging your phone slower. Changing the USB should fix the slow charging, provided it was the problem in the first place.

Laptops may also charge slowly because the USB port is a secondary power source. It wasn’t designed to charge phones; instead, it only supplies power to devices connected to the laptop. If you want faster charging, you should probably use a dedicated charger.

Check The USB And The Cable

The current output in wall socket charge is usually around 1000 to 2000 mA, while it is only around 600 – 900 mA when charging on your laptop. The current output might be lesser if you use an old USB model, which usually explains the slow speeds.

Not all USB ports on your laptop are optimized for charging; only the powered port will charge effectively. Check your device manual to identify powered ports. When you pay attention to these details, you’ll see an improvement in charging speed.

Disable USB Selective Suspend Setting

USB selective suspend setting is a power option that allows your system to suspend a particular port on your device without negatively affecting other ports.

Since other USB ports aren’t working, the current output will be concentrated in the USB port you use to charge, which may increase the charging speed.

Disconnect Other USB Devices And Peripherals

Another tip on how to charge the phone with a laptop faster is to consider disconnecting other USB devices when charging your phone. For instance, if you plug in two extra external USB devices, your motherboard will be forced to disperse power among the three.

Specifications Of The USB Port

Different types of USB ports offer different transfer and charging speeds. A laptop with USB 3.2 Gen 1 ports typically charges phones faster than one with a USB 2.0 port. They also transfer data at different rates, making checking your laptop’s USB ports necessary before purchasing.

The Maximum Capacity Of The Battery

If the battery can’t take more than a specific amperage, the charging experience will be the same irrespective of your USB port specification.

Compatibility Of The Software

Some mobile phone brands are built to limit the load to 500 mA when they detect the power source is a USB port. However, this shouldn’t be an issue with modern devices because most smartphone brands now remove this restriction from their recent phones.
