With so many mobile phones and laptops that can be in a family, it is not always possible to connect all devices to an electrical outlet. If you find yourself running out of outlets, try the easy way to connect your smartphone to your laptop and keep it fully charged, even if the laptop's lid is closed. Any laptop in running mode can charge a mobile phone, even if it is not plugged in, but things are a little more complicated if the laptop lid is closed and the laptop goes into sleep mode.

Do you know that you can charge your mobile phone from your laptop in sleep mode even if the laptop lid is closed? In this article, we will learn about how to charge your phone from a sleeping laptop, and how to charge your phone faster.

How to charge your phone from a sleeping laptop

The laptop charges the mobile phone when it is turned on, but as soon as you close the lid or put it to sleep, the charging stops. You probably don't know, but you can still charge your smartphone even if the laptop lid is closed.

To charge a mobile phone from a laptop in standby mode with the lid closed, without using a charger, you must open the device manager on the laptop and uncheck Allow the computer to turn off the device to save the power option. Let's see how to do this in detail.

First, open your laptop's Device Manager. Right-click on the Windows Start button and select Device Manager. Another way is to type "device manager" in the search box and press the Enter key.

Go to section USB controllers to see a list of USB Root Hubs.

Right click on each of them and select Properties and then tab Power Management.

Clear the checkbox.

Everything, now charging should work, even in the sleep mode of the laptop ..

If this method does not help, you may need to check USB support in BIOS laptop. On some laptops, the "USB Wake Support" option is disabled by default. In this case, in order to charge your phone from a laptop in standby mode with the lid closed, you need to enable this option.

How to charge your phone faster

Although connecting your phone to a laptop or desktop computer is a very slow way to charge your smartphone battery, you can still make it a little faster by following these tips:

• Any device, including mobile phones and tablets, charge very quickly when turned off. Turn off your phone before putting it on charge and see the difference.
• If the phone is on, then make sure your phone has no internet, if you really want to charge it faster. You can also put it into Airplane Mode to enable fast charging.
• USB ports personal computer have different power capacities. According to the specification, USB 1.0 and 2.0 has 2.5W, while USB 3.0. - 4.5 W. Therefore, always use USB 3.0 if you want to charge your phone faster.

We all know that when the laptop is turned on (working), all USB ports are powered and we can charge the phone by connecting them to the laptop. But what if you want to charge your phone when the laptop is turned off? That is, if you need to charge your iPhone or android phone when your laptop is turned off or in sleep mode?

As a rule, we charge our phones by connecting them to our computers. This works well if you are working or playing while charging. You may have noticed that if you close the lid of your laptop or your computer goes to sleep, your phone will stop charging.

You can charge your phone or any other USB device using your laptop even when your laptop is turned off, as long as your laptop supports this function. That is, not all laptops send power to the USB ports when they are disabled. The device disconnects the battery even if the phone remains connected to the laptop.

If your laptop supports this feature, one or more USB ports on the laptop will continue to receive power even after the laptop is turned off. There may be an icon next to the USB port indicating that the USB port is receiving power even when the laptop is turned off. For example, the ThinkPad 450s has a battery icon next to one of the USB ports on the left to indicate that it is receiving power even when the laptop is not running.

If none of the USB ports receive power after the laptop is turned off, check BIOS settings Usually there is a setting in the BIOS to enable and disable this feature. You can also check the user manual for your laptop or contact the manufacturer to see if your device powers the USB ports when it's not working.

Here's how you can keep charging your phone, even with your laptop lid closed or your computer in sleep mode.

The method works works in Windows 7, 8, 10.

Step 1: open device manager, in explorer, right-click " This computer", select « Properties", and click the " on the left side of the window.

Step 2: Find and expand the section USB controllers.

You will see several devices named "Root USB Hub".

Step 3: Required in every device "Root USB Hub" open Properties. In the properties window of the USB hub, click the " Power Management» and uncheck c "

Once you do this for all - USB Root Hub devices, you will be able to charge your phone, even with the laptop lid closed or in sleep mode.

By default, in "SLEEP" mode in Windows, usb ports are disabled.
Therefore, it will not work to charge the smartphone.

But, you can change the settings in Windows and then in the "SLEEP" mode it will be possible to charge the smartphone.

Right-click on "Computer" - "Properties" - "Device Manager" - "USB Controllers".
Here we will see several "USB Root Hub".

Right-click on each of them in turn - "Properties" - the tab "Power Management".
It is necessary to uncheck the box "Allow the computer to turn off this device to save power" - "OK".

After rebooting the computer, the ports in the "SLEEP" mode of the laptop will not be disabled.

The exception is the usb port in the computer, marked in red.
This color indicates that the port power is not turned off during sleep or standby.

On laptops or desktops, they are great for charging external devices such as smartphones.

There is different reasons, due to which the phone only charges when it is turned off. And this is a problem, because a modern gadget requires a large battery reserve, consumes a lot of energy, and sometimes you have to charge it while using it, watching a movie, playing games, etc. It is extremely inconvenient to do this only when it is turned off, because this way the device most of the time simply unavailable.

And in general, it is unusual to charge the phone only when it is turned off. But it is worth noting that for some models of tablets and smartphones this is the norm, which is provided by the developer. Though it's stupid, but it's true. But most often, if it is charged only when it is turned off (this also applies to other brands, but on forums people often refer to Meizu smartphones), then it is a software or hardware problem. Let's understand why this happens.

Phone only charges when turned off due to firmware

The very first and most common version is firmware. This is especially common in Chinese smartphones: ZTE, Meizu, Xiaomi, etc. These phones are sold on the basis of the Chinese shell, and there is no native crack for it. Therefore, users often install third-party software- unofficial firmware.

It is logical that such firmware, developed by amateur programmers and installed by a user without such skills, can slow down. Moreover, the problems can be very diverse: a weak range of brightness adjustment, strong heating in passive mode, fast battery discharge, conflict with the charger. It is worth noting that it is precisely because of poor firmware and software problems that something like this most often happens. It can also be related to the hardware, but it is extremely rare.

You can fix the firmware problem. To do this, you just need to return to the official version. The phones have the corresponding functionality. If not, the service center will help. But you can even try to install a new unofficial firmware, which, judging by the reviews, works well and does not crash. It is quite possible that it is your current global firmware that does not work well and causes a conflict between the charger and the gadget itself. In this case, one should not be surprised why the phone only charges when it is turned off.

Faulty power supply or battery

It is logical to look for the cause in the power supply - it can also become the cause. Checking if the power supply is working properly is easy. To do this, you need to try using it to charge another tablet or smartphone. If everything goes well, then the problem is not in the power supply. You can also try to charge the problem smartphone using a laptop or computer by connecting it via USB. If the charging process is activated when the phone is turned on, then it is worth looking for a problem in the power supply.

There is also another rare reason - low voltage in the network. If it drops below 220V, then some phones and tablets may not charge when turned on. Sometimes the power supply is so weak that it simply does not have time to recharge the phone when it is working. This applies to third-party universal chargers, so it's best to charge your phone with "native" devices.

It is possible that the problem may be in the battery itself. To check it, you need to find the same one and try to charge the phone with it. If it works, then the problem is clearly in the battery, which means it needs to be changed.

Oxidation or contamination on contacts

Contacts can also be the reason why the phone only charges when turned off. We recommend running alcoholized cotton over the contacts on the phone and charger. It might be about them. Unfortunately, this method helps very rarely, but there is always hope.

Other issues

Sometimes it is impossible to find out why the phone only charges when it is turned off. Even experts cannot always give an answer. The reasons could be anywhere. For example, a microcrack could occur in the power circuit during a fall. Also, some kind of micro-rupture could occur inside the cable. It is impossible to determine all this at home, and sometimes it does not work even in workshops.

But if charging fails, then you should not be upset. By itself, it is insignificant. The main thing is that the smartphone works normally and performs its functions. Still, most users put their phones on charge only in the evening, when they themselves go to bed. And there is no special need to charge it during the day. So sometimes you just need to put up with it and not pay attention to such trifles.

Which phones are at risk?

This problem is not uncommon. Many users have such situations. Chinese cheap smartphones are more likely than others to work in this way. However, on the forums you can find messages that Russian Explay phones are only charged when turned off, but this does not apply to the entire manufacturer's line and not even all models. It just happens, and not only with cheap Chinese state employees, but also with expensive flagships.

There are universal methods to increase the duration of work mobile devices

Phones are constantly improving, decreasing in weight, becoming thinner, their processors becoming more powerful, their screens increasing in size. And with all this technological progress, the load on batteries is increasing.

Phone manufacturers are constantly trying to extend the life of the batteries in their devices. But with everyday use, batteries without recharging also last an average of one to two days. Moreover, the functionality of devices, the resource intensity of programs, and the frequency of using phones are also growing. This all leads to even faster depletion of the batteries. It is enough to run any program on the phone, spend several hours on the Internet, and the battery will remind you of itself by requesting recharging.

At the same time, there are certain universal methods for increasing the duration battery life mobile devices. Let's consider these methods in more detail.

1. Disable Auto Brightness. When in Auto Brightness mode, your phone adjusts the brightness of the screen to match the light level in the area where you are at that particular moment. At the same time such useful feature in general, it is in demand only on the condition that you move around a lot, respectively, there is a change in the strength of lighting (street - transport - office, and so on). In the event that you are in a room with a stable level of lighting most of the time, it will be beneficial for you to turn off the Auto Brightness mode. Set the most acceptable, convenient brightness mode for you, for sure, you will have to significantly reduce the brightness mode set automatically by the phone. And all due to the fact that the standard light control sensor changes the screen backlight mode even when it is not necessary to do this at all. The light sensor in real mode reacts to shadows falling on the phone screen, glare of light, to light from a computer monitor, lighting fixtures. And this effect occurs constantly until the phone screen is on and it does not automatically go into sleep mode, auto-lock mode. And this, of course, is the work of sensors, energy consumption, premature, accelerated discharge of the phone's battery.

2. Disable "Auto Screen Rotation". This useful function will also not be in constant demand at all, at the same time, the accelerometer - a sensor in the phone that reacts to turning the phone from a horizontal position to a vertical position and vice versa, will consume significant amounts of energy that could be spent on more necessary, often necessary telephone conversations.

3. Reduce auto-lock screen time(there may be a “screen timeout” item in the settings). By default, the phone from the store, as a rule, has a period of one minute. That is, after one minute of inactivity, the phone goes into sleep mode, standby mode, while the screen is automatically extinguished and locked. It is important to understand that the shorter the interval for switching to sleep mode, the more economical the power consumption of the phone.

4. Clean up the phone's RAM. After working in any application for the phone, do not forget to close it. Staying in random access memory phone, applications continue to constantly use the system resources of the device, thereby consuming battery power and shortening the battery life of the device. A similar remark applies to the so-called installed "live wallpaper".

5. When working on devices with an Amoled display it is advantageous to install a completely plain black wallpaper on the screen. In Amoled, power consumption directly depends on the brightness level of the screen. Such screens require more energy if bright, light wallpapers are installed, they consume even more energy than LCD options. Reduce screen brightness while applying dark background screensavers.

6. Change the reader mode in the device to "night"(or inversion). Reading books or any other text directly from the phone screen is very energy intensive. However, here you can go for a little trick. The inversion will change the background of the screen to black, while the font will become white instead. Thus, we will fulfill the condition from the previous paragraph. A dark screen as a result will consume less energy than a white one, like a sheet of paper.

7. Disconnect bluetooth modules and WiFi. Modern devices have a function to automatically turn off these modules, but they are turned off only when the device enters sleep mode. Therefore, it is safer to disable them manually. Similarly, when not using the machine, turn off all online services, email. It is also beneficial to save battery and turn off all system reminders and messages. Disconnect the machine from 3G networks. Such simple operations allow you to extend the work of the phone without recharging for several hours.

8. Turn off vibration and vibration feedback on your phone. The vibration motor that sets the phone in motion consumes a lot of battery power, turning off the vibration will not cause much inconvenience to the user, at the same time it will allow you to use the phone for a longer time.

9. Observe the temperature regimes recommended by the phone manufacturer. A comfortable temperature, and for a phone it is in the region of 15 - 25 degrees, will extend the life of the battery, reduce the rate of its arbitrary discharge, and prevent malfunctions in the device.

10. Install additional applications, allowing to carry out a full cycle of recharging the battery with a low current. This is, for example, BatteryDoctor, the program implements careful control over battery consumption, and this has a positive effect on the battery life of the phone from a single charge.

Thus, the proposed tips available to everyone will guarantee to extend the phone without recharging up to four and even up to six hours.
