If you are worried about charging the battery when the phone is connected to a computer, you have to know that you cannot turn off the charging mode because the phone does not has settings to disable it manually.
But don’t worry, you still have a method of doing this. But it needs some technical knowledge. If you still needs to turn off charging mode, then try the following, and it will definitely work.
You can modify a USB cable to only carry data. You can do this indefinitely by:
- Cutting the cable, then reconnecting all wires except the power wire (which is almost always red), or
- Severing the wire in the middle and severing the power wire (this may be messy with a high-quality shielded cable). See DIY Data Only USB Type B for more information.
- You can also use tape to temporarily block the power pin, as shown here:
- A quick and easy non-destructive modification for a data-only (no power) USB cable.
If you don’t think you have that technical ability, then you can still purchase a USB data cable where the power wires are disconnected.
Is it safe charging a phone via a computer?
Those experts who oppose charging a smartphone via a computer’s USB ports cite potential battery damage as their main argument.
In reality, most users connect USB hubs to their computers, and smartphones are already being charged via those hubs. Some people charge their devices via the USB ports on the PC case.
It is critical to understand that the current of such connectors (including USB hubs) is insufficient to provide sufficient voltage for smooth but fast charging.
As a result, charging the smartphone from such connectors will take longer than charging it directly from the motherboard’s USB port or from a power source plugged into a power outlet.
What are the advantages of charging a phone via computer?
The benefit of charging a phone via computer is you can work on your computer with the phone files right away while it is charging.
Despite the fact that most movies, music, books, and other content can now be viewed on smartphones via various services, some users may find it more convenient to download their favorite music directly from a computer into the phone’s memory.
It makes sense, for example, if the smartphone is frequently used without access to the Internet and you need to stream music from it.
How to disable USB charging when the laptop is off?
Sadly, there is no way to disconnect the power supply to the USB ports when the laptop is shut down. So what you can do is disconnecting the phone from the laptop.
You have to notice that when a phone is connected to a laptop, it always discharges the laptop battery. So when it is not necessary, keep the phone disconnected.
How do I fix my phone when it doesn’t charge?
Assuming nothing is physically broken, the battery is functional, the charge port is functional, the cable is functional, and the charger is functional, there are a few methods you can try to “bump start” a phone into charging.
First, try holding power and volume up for a few seconds; if it vibrates, keep holding; if there is no vibration, hold them for about 10–15 seconds before charging.
If it doesn’t charge, remove the cable, wait a few seconds, then press and hold the volume up key while inserting the cable; it should vibrate, and your notification led, which is usually blue or pink, should flash or stay on.
If nothing happens, pull the cable and release the button. Wait a few seconds, then repeat with the volume down key; if there is still no light or vibration, your motherboard is likely dead, or the port has detached.
Does the laptop USB port support fast charging?
No. The laptop USB ports do not support fast-changing because they are made for the purpose of transferring data.
What really is fast charging?
Being able to fast charge your phone or tablet can make the difference between hours of worry-free use and scurrying to find a power outlet at the local coffee shop.
Fast charging is an increasingly popular function that allows you to charge your device in a fraction of the time it would normally take.
However, not all items employ the same form of rapid charging, and not all chargers support all of the different standards. Here’s what you need to know to ensure that you get the fastest charge possible.
What do you need for fast charging?
The fast-charging standard you can use will differ depending on the device you have. Check to see what your phone supports, then check to see if your wall adapter supports the same standard (they’re usually labeled).
Then, ensure that your cable is compatible (you should use the one that came with your phone or adapter). If you need to purchase a new wall adapter, cable, or wireless charging pad, make a note of the standards that it supports.
How do I stop USB charging while tethering?
As I’ve mentioned above, you cannot stop charging when your phone is connected via a USB cable. It happens because of the voltage difference between the PC USB port and the phone battery.

How much power does a USB charger have?
The majority of chargers are rated at 5 volts. However, some can pump greater voltage for a speedier charge. For example, 4.8A output gives the maximum power for three Android smartphones, but increasing the voltage is the only option to charge them faster. This will charge the smartphone around 20% faster.
Is it true that more watts equal faster charging?
Wattage is the total amount of power that flows through your charger, so a higher wattage means that your device will charge faster.
