Have a Wireless device on PC this is something very normal today, especially when we talk about mice or headphones. These devices, of course, need charge your battery, and it’s pretty easy that when we’re done using them, let’s leave them connected and let’s forget about them for a moment. Does this damage the battery or nothing is happening? Coming up, we tell you.
The wireless device battery and its autonomy is a problem that everyone worries about, because if you are not careful, over time the battery will last less and less until there comes a point when we are forced to replace the battery with a new one or even throw away the device for a new one. The battery maintenance for a wireless PC device, they are exactly the same as for any other battery-operated device, such as a laptop or smartphone.
What happens when you charge the battery of your wireless device?
If we extrapolate wireless devices to the laptop environment, the old recommendation was remove the battery when we used it with the power connector on, but it’s complicated when we talk about a mouse or a wireless headset, because the “grace” is to use them without cables and to only connect them ‘if needed. charge your battery
However, it is common, especially in headphones, to leave them plugged in for a long time, until we use them again. And, unlike laptops, these devices do not charge their battery by connecting them to power but, as a rule, they do so from a USB port on the PC. And this is where the main difference lies, not least due to the fact that it is also very common to leave the devices connected to the PC switched off.
When you charge a laptop battery, the power supply has a control which detects when the battery is already charged and turns off the power, so there is absolutely nothing wrong with a laptop as it is always connected. However, a wireless device does not have power as such … does it?
As long as it is connected, the USB port of your PC will provide it with the 5V of energy that it is able to transmit (the amperage depends on the port, normally it is able to deliver between 0.5 and 0.9 Amps ), by recharging its battery. Obviously, there is no power supply that controls the load, but all modern wireless devices also have a control chip built into their own electronics to control this and, like a laptop power supply, cut off the charge when the battery is full.
For this reason, and whether you are connecting your device wirelessly to a PC USB port, an externally powered port hub, or even using the mobile charger to charge its battery, absolutely nothing is happening to leave it logged in for as long as it is. Of course, when the power goes out, the battery will gradually discharge gradually, and depending on the programming of the chip, reaching a certain level (normally between 95% and 98%) will recharge the battery until it reaches 100% again, which is not quite good for its lifespan.
Therefore, the answer to the question is that it is okay to leave your wireless device connected overnight or even for several days, but it is not good either because if we leave it for so long that the battery will drain. and jump on charge again, we will “consume” the charge cycle little by little, reducing the useful life of the battery.
Of course, this “standard” is valid for devices of a certain quality, because when it comes to mice or OEM headphones of dubious reputation, it is possible that they do not have the chip that controls. charge of the battery and that, therefore, they are not able to cut off the charge when it is full, overcharging could occur with its disastrous consequences. This is not normal, but when it comes to really poor quality devices, it is a possibility that we cannot ignore.
Where is it best to charge your device?
Generally, and unless otherwise configured in the BIOS of your PC (moreover some BIOSes do not allow you to deactivate it), the motherboard USB ports
This means that if you connect your device wirelessly to one of the rear ports on your motherboard and turn off the PC, your battery will continue to charge, something that is ideal for recharging your mouse or headphones at night, with the PC off when not in use, and thus find them full of power for the next day. The same thing happens if you use a USB port hub, either one that has an external power supply (i.e. with its own plug) or if you have connected it to one of these rear ports of the motherboard.
Things change with front ports of the box; in this case, the connector is internal and whether it continues to power the switched off PC or not depends on the motherboard itself. Personally, we have not found any setting about this in BIOS or elsewhere from any motherboard manufacturer, and with some models it works and with others it does not. Anyway, the normal thing in this case is that when the PC is turned off the front ports stop supplying power and therefore it is not advisable to use them to charge the battery of our wireless devices (at least not with the PC turned off, well, when it is turned on, they are used for this).
