On smartphones and tablets on Android based There is a so-called background mode, in which data is transferred between applications installed on the device and the server. In the background, applications can receive updates or, for example, receive notifications from those applications. The simplest example— the same messengers: when a message arrives, you receive a notification on your smartphone. Of course, if the device is connected to the Internet.

Not everyone has the background mode enabled - in some places it is disabled by the user, in others it is disabled by default. But this is not a problem, turning it on is as easy as shelling pears. Let's show an example on stock Android and Samsung smartphone with proprietary TouchWiz firmware. Let's start in order.

Android firmware

Go to “Settings”.

Select “Data transfer”.

Click on the “Settings” button in the specified section. This can be a button below the screen, or a button on the screen in the form of three dots. In our case, the first option is used. A small menu will appear in front of you; in it, uncheck the “Background data limit” item.

No checkmark means that background data transfer is enabled.

By the way, if the background mode is limited, you will see a corresponding notification under the curtain. Click on it and the background mode will be automatically turned on.

TouchWiz firmware (Samsung)

Go to "Settings".

Select the "Data Usage" section.

In this section, click on the “Settings” button so that a small window appears, as in the image below. Uncheck “Limit background activity.”

The checkbox is unchecked, which means that data transfer in the background is working.

Or you can simply click on the corresponding notification under the curtain to remove the background limit.

Android is the most popular operating system For mobile devices. More than 70% of smartphones and tablets in the world run on various Android versions. Among all the advantages of this OS, there is one drawback - an exorbitant appetite for system resources. Of course, flagship models have powerful enough hardware so that you don’t experience any discomfort while working. But what should owners of less powerful devices do? Our selection of tips will help you optimize the performance of your smartphone or tablet for comfortable use.

Use static wallpaper

Android makes it possible to install so-called “live wallpapers” - animated pictures of different content - on the desktop and lock screen. It's beautiful and stylish, but it consumes quite a lot of processor resources and RAM. Especially if you have multiple desktops. If you set a regular picture as wallpaper, you will reduce the load on system resources, and therefore increase the performance of your device.

Disable unnecessary processes

In the operating room Android system The number of background processes may exceed 50 even after a reboot. All these proprietary utilities that equipment manufacturers love to install, Asian keyboards, printing processes and other unnecessary things consume RAM. By disabling processes that are unnecessary for you, you will free up several tens of megabytes of RAM. This will have a positive effect on the responsiveness of your device.

• To do this, go to settings and go to " Application Manager" On the " Performed» select all one by one unnecessary processes, and press first " Stop", and then " Disable" You can disable all unused programs.

Don't disable processes with robot and gear icons!

Limit background processes

Most Android applications continue to run in the background when closed, consuming energy and system resources. You can limit the number of programs that can run in the background. This is done in the developer menu, which is hidden from the user by default.

• In order to activate the developer menu, go to settings, select " About the device", and scroll down to " Build number" Now quickly press this item seven times in a row.

• After this, the section “ Developer Options" Open it. Find the item " Limit background processes ", and set the value to " no more than 3 processes».

Don't fill up your device's internal memory

No matter how strange it may sound, but the less free memory your gadget, the slower it will work. Therefore, try to keep free an amount of memory that is twice the amount of RAM on your device. If your smartphone or tablet supports memory cards, transfer all your music, videos, photos, and books to the card. Also, if possible, install large applications and games only on the memory card.

That's all. By observing these simple tips you will increase the performance of your Android device.

And remember, if you don’t know what a particular item in the developer menu does, do not change its parameters. Ask the experts first :)

Hello, friends! In this short lesson I want to talk about the background mode and why it is needed at all. Most programs that a user runs on a computer run in active mode. This means that they are displayed on the panel Windows tasks and in the task manager on the Applications tab. If you look at the “Processes” tab, you will find a much larger number of entries there than in the applications tab that are currently running. You can read more about the task manager and how to use it in my article “”.

If you open any program, you can see this running program in the task manager in the “Processes” tab. For example, if you open Opera browser, then you will see the “Opera.exe” process running. If you open the task manager, go to the “Processes” tab and check the “Display processes of all users” checkbox. With this action you will display processes running on the computer under other users, as well as system processes, which are necessary for normal operation.

All processes that do not require user interaction usually run in the background. Running a program in the background involves independently performing the tasks assigned to it, without the participation (or almost without participation) of the user.

Programs running this way consume computer resources in the same way as applications that appear on the taskbar. Therefore, running a large number of programs that hide their icon in the tray or do not remind you of themselves at all can greatly affect the performance of your computer.

Normal programs can run in the background if configured accordingly. In this case, the application icon is usually displayed in the notification area (system tray or in English system tray - part of the taskbar between the clock and active tasks). Antivirus can be considered the most typical representative of this group. If you close the main antivirus window by clicking on the “cross”, the window will disappear, but your antivirus will continue to protect your computer by moving to the tray. Some programs can be configured so that when you click on the “Close” button, they stop working completely, and when you click on the “Minimize” button, they disappear from the taskbar, but show their icon in the tray, thus moving into the background. This setting is usually called “Minimize to tray”.

Also running in the background are programs that are part of the operating system. In particular, these are system services, as well as other applications. Some of them are necessary for the system to function and cannot be stopped. Others are needed only for some specific functions that are not actually used by the user. Stopping such components can be very useful for saving computer resources, but it requires knowledge, the description of which is beyond the scope of this article.

There are also viruses running in the background, spyware and other malicious objects. Which is understandable, because the attacker wants the user not to know about their activity and tries to hide it from the user’s eyes.

To terminate processes, you need to know a little about system programs, which are usually used for work.

Backgroundapplications/processes are called, which work in the background (hidden from the user) mode.

Some of them are not used by the user, nevertheless consuming system resources and, accordingly, reducing the efficiency of equipment use; some simply litter the taskbar, desktop and list of installed programs.

Some of these programs are various services, launched by the operating system. Due to its versatility, the operating system runs a large number of applications, some of which you will never specifically need. In addition, some of the background applications in turn launch their own background applications, such as MS Office. Removing applications you don't use will help speed up system startup and free up computing power.

4. Bring your device to the service center for repairs

1. Basic types of background applications

You can view running applications in the Windows taskbar. As a rule, these are various download managers, antiviruses, “daemons”, “wizards”, and other useful and not so useful utilities. Those that are “not so good” end up on your machine in different ways: in addition to files downloaded from the Internet, during installation various programs the “default” method, etc. After spending a few minutes disconnecting unnecessary applications and services, you can improve the performance of your hardware. Background services compete with user tasks for memory, increasing the number of calls to the page file, thereby reducing the efficiency of the entire system.

2. Ways to detect and remove background processes

To view the list of applications that launch automatically, press .

“Honest” programs are reflected here; you can remove them from startup with the right key - “delete”; in this case, the program itself is NOT deleted, it just stops loading automatically when Windows startup. Others background programs"hiding" and we need to be able to look for them.

Pay attention to your computer's taskbar (usually the lower right corner). There are shortcuts to programs that are launched by default

In this case, we see the uTorrent download manager, 2GIS update agent, Skype, disk emulator DAEMON Tools lite and others.

Fig.2. List of programs in the taskbar

The programs that we see in the taskbar can be unloaded by pressing the right key:

Fig.3. Shutting down (unloading) programs

Comment: when using the Exit button, Exit the unloaded process when restarting windows starts again. If you need to turn it off permanently, use msconfig, regedir.

2.2 Using the task manager ( ctrl+alt+del)

By launching the Windows Task Manager (by pressing Ctrl+Alt+Delete), you can look at the list of background services. Windows distinguishes custom applications and system services. On the "Applications" tab you can see running programs, on the “Processes” tab, a list of system services and application components.

Fig.4. Task Manager, Applications tab

The End task button can be used to kill a program or process

In the Processes list you can see the same programs that we saw on the taskbar and more. For example, the explorer.exe component is a familiar one Windows Explorer, and iexplore.exe – Internet browser Explorer.

Fig.5. Task Manager, Processes tab

Modules you don't need can be removed by clicking the " End the process" You can safely delete processes:

TweakUI (tweakui.cpi) - operating system configuration utility;

MS WebCheck Monitor (loadwc.exe) – configures Microsoft Explorer on first launch;

ShedulingAgent (mstask.exe) - task scheduler (if not used);

Microsoft Office Wrapper (osa.exe) - launch accelerator for MS Office programs;

File Open (findfast.exe) - speeds up searching in office documents

Internat.exe - keyboard layout indicator;

System Tray (systray.exe) - a program that creates icons in system area Taskbars.

Comment: The unloaded process starts again when Windows is restarted. If you need to turn it off permanently, use msconfig or regedir.

2.3 Via MSCONFIG (SCU)

On Windows there is special utility System Configuration Utility (SCU). It can be launched by specifying MSCONFIG in the program launch line Start ->Run. It is simple and easy to use and allows you to manage running applications. The utility contains several tabs that allow users to change OS startup parameters.

The information we need is located on the Startup tab and contains a list of applications that start when booting Windows. On this tab you can disable them as needed.

Programs, the list of which we see in SCU, are deleted there. SCU allows you to experimentally significantly increase system performance and remove all unnecessary things. Once you find a program you don't need, you can remove it from the download list in the SCU panel.

Fig.6. SCU Utility (MSCONFIG)

2.4 Through the Windows registry (regedit)

Programs that are registered in the system registry, can be deleted using the program REGEDIT(keyboard shortcut win + r, team regedit.exe). As always, before making major changes to the system, we do a backup and, as always, we do this only when we are completely confident in our abilities. Most often, such programs are located in the branch HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Removal from the program is carried out by deleting the corresponding registry line.

Unfortunately, not all programs can be removed using the methods listed above. Microsoft will not allow you to delete, for example, Windows Messenger. This rather useless program is installed by default, and is not visible in the Add or Remove Programs dialog of the Control Panel. If you want to remove one of these programs, you will have to edit the file SYSOC.INF, which is located in C:\WINDOWS\INF default. To do this, first find the title , which contains options for loading various Windows components. Those that contain the parameter "hide"- the Add/Remove Programs panel is not visible, for example msmsgs = msgrocm . dll , OcEntry , msmsgs . inf , hide ,7 in the case of Messenger, after removing this parameter, the component becomes visible in the Add or Remove Programs panel.

3. Background services, pages and other processes

In addition to background applications and processes, there are also background pages, services, etc., but we will talk about them next time.

In Android, once you launch an app, it will run in the background, even after you close it and move on to other tasks. When enough applications are opened in one session, you may notice that the device is running slower, due to the number of open applications devouring RAM your device. This isn't a huge problem for newer, faster devices like the Galaxy S4, but less powerful devices suffer more when there are too many apps open. Additionally, if someone picks up your smartphone, they will be able to see what apps you are using, which opens up the issue of privacy.

Here's how to close apps running in the background that you no longer use.

1. Open the recent applications menu. Access to this menu may vary from device to device. On HTC One, for example, you must press the Home button twice to open latest apps, while the same menu opens physical Samsung button Galaxy S4, and on the Nexus 5 there is a dedicated button on the screen for this.

2. Find the app(s) you want to close, in the list by scrolling from top to bottom.

3. Touch and hold the app image and drag it to the right. This action should close the application and free up some RAM.

4. Go to the "Applications" tab in settings, if your smartphone is still slow. On Samsung phones this menu is called "Application Manager".

5. Select the "Running" tab to see apps that are still running.
