On Google Play the so-called “killer” processes are the sea. It seems that Android is a buggy operating system that constantly freezes, and all processes have to be deleted manually. It's just the opposite - Android is better any OS knows what and when to “kill”.
What does a task killer do?
Let's get into the swing of things. Process managers (task killers, “killers” of processes/tasks) are applications that clean random access memory (RAM) from processes. The goal is to speed up the device. At least that's what the developers promise. The most popular “task killers” are , Clean Master, Easy Task Killer.
"Task Killer" allows you to clean RAM manually. The application interface is quite universal - there is a “Kill processes” button everywhere, and at the bottom there is a list of active processes that you are going to kill. In the settings, you can set a process filter - choose which of them the program should ignore and which should always be deleted. The function is also available automatic cleaning RAM – processes are erased from memory as soon as its percentage reaches a set point, for example, 90%.
How does this affect the system?
Cleaning random access memory does not harm the Android OS - it just disrupts its harmony.
There are system processes, and there are user processes. System processes ensure the operation of the OS and applications by default, for example, checking for updates on Google Play. User processes, roughly speaking, are applications that you installed from Google Play. Usually these are toys, players, readers and editors - they are needed in RAM when the user interacts with them directly.
After clearing the RAM, it will only take 10–20 seconds before all system processes are restored again. True, there will be no more user processes. As a rule, these processes take up a small percentage of RAM.
User Processes
There is a reason that user processes hang in RAM for some time - this is convenient if you work with several applications at the same time. For example, you are using a browser and press the “Home” button (or someone called you), then the browser (process) remains running, only you do not see it, it is running in background. You looked at your mail (or talked) and returned to the browser again - it launched instantly. The browser does not load again because it has been in RAM all this time. If the RAM in the device is low, the browser process will be deleted by the system as soon as you open the mail.
The only important moment for the user is when one process is removed from the “background” and a new one is launched in its place. This usually takes a split second. But if the device is cheap (low RAM, no processor), then your smartphone or tablet will freeze for a second.
It turns out that if 70% of your RAM is occupied by “immortal” system processes, and only 30% is for you, then the OS will constantly kill some and bring other processes to the foreground. That is, a weak smartphone will freeze all the time.
If system processes take up about 40% of your memory, and the remaining 60% is yours, then most likely you have a powerful smartphone/tablet, and replacing processes in RAM will be imperceptible.
Results
A “tax killer” is not needed for more or less powerful devices (from 512 MB RAM) - the system will do everything itself. For a budget device (RAM from 128–256 MB) it is almost useless, since system processes are resumed in a few seconds. Only in rare cases is it convenient to clean processes, when the smartphone completely freezes (in such cases, restarting Android will help better).
What should someone who has a budget device do? The simplest thing is to develop the habit of exiting the application completely, instead of using the “Home” button, use “Back”. Let's compare it with Windows (as far as possible): “Home” is to minimize the window, “Back” is to close it. If you do this, there will be less freezing.
A more complex option is . Root rights will allow you to disable application processes that were installed by default (Google Play, Gmail, google maps etc.). Be careful here: Root rights are a responsibility: before you “kill” something, figure out what it is.
To obtain Root rights time will pass, and experience with Android is required. There are, of course, programs that “root a smartphone with one click,” but most often various unforeseen nuances arise - it takes several hours to resolve them (if for the first time). In addition, if you make Root rights, you will lose the warranty on the device.
Well, the surest option is to not suffer with a weak smartphone or tablet. Pay a little extra and buy yourself a device of at least medium power: at least 512 MB of RAM, one core is enough. Then you can forget about process managers forever.

IN Android system 4.x there is one very useful tool, this Application Manager(Application Manager in more earlier versions OS). This remedy is available in every mobile device running the Android system and you can find it in the menu Settings – Options – Application Manager.
When we open the Manager, we get a window open at first tab out of three possible ( Loaded, Running and All) – this is a list of all the downloads you have downloaded from the market. GooglePlay applications, indicating the total amount of memory each application occupies.
The list can be sorted alphabetically or by size by pressing the left soft key devices. Please note that at the bottom of the screen the total occupied space of the device’s internal memory card is shown and how much is left free.
When you select one of the applications in the list, it opens properties(size of application, user data and cache), as well as a series of keys for stopping the application, deleting it, moving to and from an external SD memory card, deleting user data and clearing the cache, and after scrolling the screen - reset to default settings and list of permissions for this application. Reset Settings to Default can be done if you have defined this application the only one (choice Always execute), which opens files of this type or performs this operation when choosing from several possible ones.
Moving apps to an external memory card can be done when you lack internal memory to install new applications. But you must keep in mind that not all applications allow such transfer; in this case, the transfer button is inactive.
When switching to second tab(moving your finger to the left) we get a list of all those executed in this moment applications that occupy random access memory (RAM), and below is the amount of occupied and free parts of RAM.
In ALL tab shows not only the applications you downloaded, but also all the system applications included in the package operating system. System apps cannot be removed, but some of them can be temporarily disable the corresponding button if you do not need them.
You can also remove any updates that were previously installed for them. But these operations must be done with the understanding that after this some applications associated with the disabled ones may not work properly. Be careful.
Smartphones have become an integral part of the lives of each of us. We use them everywhere - at home, at work, on vacation, etc. When downloading documents from the browser, it opens special utility– download manager for Android. What is it, how to use it and where is it located - read on.
How to work with the download manager.
Download Manager for Android – special program, which allows downloading documents from the Internet. With its help, you can easily use images or programs that you found on the Internet through a browser. just highlight them in your browser and the program will launch automatically.
Where is
You can find the download manager on Android in the smartphone menu. It usually only works with standard browsers. You can add downloads yourself. To do this, copy the URL of the desired document to the clipboard, go to the program and add . To use downloaded documents, you need to open Explorer and go to the Downloads folder. Here you will find all your downloaded files. Over time, they can seriously clog the system, so periodically look into this folder and delete old ones unnecessary files.
How to turn it on
If you can't navigate to your smartphone's menu, the app may be disabled and needs to be enabled. You may also experience difficulties using files you download from the Internet.

Download Manager is a standard and necessary application that comes with all versions of the Android OS. Typically, disabling it is necessary if you decide to use a third-party manager, which Play Market thousands.
The Android operating system is the most popular in the world. It has a record one billion users. No other company producing software for smartphones, tablets and communicators has been able to achieve such a result.
What is Task Manager used for?
These types of applications allow you to view all running processes and applications in real time. Overloading the device's RAM can cause freezes and slowdowns. Every gadget owner should have a task manager for Android.
Remote control also allows you to control your phone's memory, cache level, unwanted calls and SMS. Some types of this software are able to scan the device for viruses and other spyware, which can steal personal user information (passwords, credit card numbers, website logins, etc.).
for Android. Properties Overview
The team of developers of the most popular explorer in the store has released its new project - ES Task Manager - to the public. The application has a very simple interface, which allows even a novice user to understand the essence of the work and control the state of the system and RAM of their device.
Task Manager for Android ensures stable and uninterrupted operation of your tablet or smartphone. The memory should be cleared every few hours. Main properties of the ES dispatcher:
- Clears temporary files and outdated system cache data.
- The program is able to analyze which utilities the user does not enable at all. If there are such applications, the dispatcher will offer to get rid of them in order to free up space in the memory of your phone or tablet.
- The utility can clean a large number of running programs simultaneously by dividing them into groups.
- ES task manager for Android analyzes the state of the device's memory card.
- Displays information about battery power and the approximate time until the end of charging.
The best task manager for Android. Other application options
In this guide, we'll look at Android utilities that perform system diagnostic and optimization functions and allow you to better understand how available resources are used.
One can be understandably skeptical about all kinds of optimizers, familiar from the days of “tweakers” for desktop OSes. However, it is undeniable that such applications should always be at hand, since the available tools of the Android OS do not allow you to fully, comprehensively obtain information about processes, perform a number of batch operations, etc.
Key review participants:
Also mentioned:
Assistant for Android - a selection of tools for optimizing Android. This toolkit includes 18 basic system optimization functions. Among them are monitoring, process and task management, cleaning of unnecessary files, startup manager, application manager and other components.
On home page diagnostic information about the system is displayed in real time, these are: processor load, RAM, ROM, free space on the memory card and internal memory phone. It is appropriate to add a number of widgets to the home screen for quick access to information of interest.
In the “Monitoring” section, the user can unload applications from RAM (task manager) or clear the system of unnecessary data - cache of temporary system files and installed applications, log files, empty files/ folders and other “garbage”, the removal of which has a harmless effect on the system. In addition, Assistant provides a list of temporary files on the memory card, a selection of user files by size, type of information, etc.
The next section of the application is process management. Here you can get information about the types of processes (marked accordingly), the memory they occupy and the load on the CPU, and track the behavior of certain processes - in case there are issues with system performance. According to what unnecessary processes can be unloaded from memory.
The third section contains options that allow you to optimize the device's battery consumption. At the top of the screen are network management, brightness, sound, vibration and other options (also available through system widgets). Below are various service applications that are useful in optimizing the system: batch uninstallation / installation of programs, creation backup copy, moving applications to an SD card, startup manager, file manager, battery and system information, setting rights. In general, as you can see, there is nothing remarkable here, and the main value of the collection is the availability of system functions in one section.
Summary. Assistant for Android is quite a traditional optimizer for Android with a comprehensive set of functions. It does not introduce anything fundamentally new and is only a convenient shell for tuning the system. The main advantages are a simple interface and the absence of useless marketing add-ons, batch operations with applications.
The System Info for Android application provides various kinds of service information on the operation of the Android OS, which can be useful for subsequent system optimization. Let's look at the main functions of this program.
The system panel provides summary information on the occupied space on cards and memory, RAM, operating time and network information (IP address, type of network connection, etc.). At the same time, it is very strange that there is no data on the processor and its load.
In the System tab, all information is presented in text form. It is in no way applicable to optimization and, at the same time, provides comprehensive information on the Android system, the hardware component as a whole: OS, configuration, memory, battery and other aspects that affect performance.
The next section, Tasks, allows you to view and “kill” unnecessary processes and obtain information on processor and memory load. This section is a little more useful from a practical point of view, but in terms of convenience it lags somewhat behind similar components in similar applications. Sorting is available, but the developer did not provide color coding for processes or their categorization. Therefore, it is actually difficult to control the processes.
The Apps section contains all installed and system applications. Here you can manage each program individually, but there are no batch operations (for example, installation and removal) as such.
Finally, the Logs section can be useful not only for users, but also for developers who are testing an application and want to extract debugging information. Logs are updated in real time, you can save the history to a file.
As an option, you can add a widget to your home screen. Its capabilities are more than modest: it displays information about battery charge, free RAM memory and occupied space on the SD card.
Summary. Thus, the System Info for Android application will be useful to ordinary OS users, and partly to developers. Rather, it is an information-oriented tool that allows you to track processes and events in the log in real time. There are only a few useful optimization options related specifically to settings.
Elixir 2 is a utility for obtaining system information, diagnosing the device and adding appropriate widgets to the home screen.
Let's start with the functions that similar applications have. The “Information” section contains summary data about the device: available disk space and RAM memory, processor status, battery charge, telephony, current location, screen and sound, operating mode, camera, external devices, etc.
Also worth noting are the additional features available through context menu. Elixir 2 offers features associated with each selected component. For example, by selecting a processor in the menu, you can view data about its model, battery usage, and change the CPU regulator. Mounting and application management are available for the memory card. Thus, Elixir offers a fairly convenient and logical layout of related system functions.
Next in the application is the Application Manager. This section contains information about installed applications, the space they occupy and their location. Advanced sorting is available (for example, by code or cache size), and there is a text filter. Conveniently, you can enable batch mode and quickly uninstall all unnecessary applications.
One of the most interesting functional features of Elixir is the Sensors section. Accordingly, here you can view the system data and consumption of the available sensors of the Android device. In addition, you can manually run tests to check their minimum and peak power.
"Logs" displays the contents of logcat and dmesg files and allows you to filter messages (errors/warnings/info). Generated Elixir reports with system information easy to send by email.
Finally, it should be noted the variety of widgets. To activate and configure them, you need to install the add-on. This and other add-ons (personal, system, administrator, etc.) are installed optionally via Google Play.
Summary. Elixir 2 is one of the most powerful applications in its category, it is definitely recommended for installation. Allows you to manage system resources, diagnose the device and system resources. Excellent capabilities for managing system components, competent grouping of functions and the availability of everything you need.
DU Battery Saver is an application for basic system optimization and battery saving. There are no fine adjustments here; it is very simple and is unlikely to be of interest to experienced users.
On the main page (“Battery”), information about the current battery status is available. If the device is charging, you can find out the time required to fully charge. In addition, from here you can extract some specifications: temperature, voltage and battery capacity. On the graph at the bottom of the screen, the user can track how the battery charge was consumed throughout the day, based on the battery level. Everything is clear from this scale, but there is less practical meaning in it than we would like.
In the “Saving” section - management of consumption modes. Profiles have descriptions, so you can understand how you plan to optimize your phone: calls, SMS, Internet, etc. You can create your own profile from dozens of parameters. Users of the paid version of Battery Saver have access to the so-called. “smart” mode: turning off notifications, managing applications, auto-unloading, changing energy consumption profiles throughout the day.
The Monitor tab monitors the energy consumption of applications and equipment. Here you can clearly see what drains the battery the most; the “culprit” can be disabled.
The Battery Saver application has other functions, but they are less interesting, plus, like other applications from this developer, some functions are purely advertising.
If you don't have enough free space on your phone, the best thing to do is to search for and delete unnecessary files, starting with the largest ones, and descending in size. DiskUsage - small system utility, which helps to visually and quickly determine which files and how much space are taking up on a memory card or other source.
Data is displayed on the chart as colored blocks proportional to the space it occupies. By clicking on a specific block, you can view the files inside this directory. Thus, it becomes clear where to look for “thieves” of disk space.
Among the additional features of the application, DiskUsage integrates with popular file managers such as OI FileManager and Astro.
One of the most famous utilities for accelerating CPU and memory and, in combination, an application manager. Contains several useful modules that help clean the system.
So, “Trash”: in this section you can clear the cache and various temporary files that applications leave behind. In addition, the advanced cleaning mode is interesting - it allows you to identify duplicates and files that take up the most disk space.
The “Acceleration” section allows you to free up phone memory by unloading applications in the background. In “Acceleration” you can also go to the startup section, where the corresponding list of applications that are active and disabled from startup is displayed.
Another useful Clean Master module is the application manager. Applications are presented here in the form of selections: recently installed, rarely used, by size, category, etc. You can mark multiple items and delete them in batches, which is very convenient. In addition, it is possible to create a backup copy and delete apk application installers.
Clean Master pleases with its information content regarding optimization and allows you to be aware: information about occupied/free megabytes is constantly displayed at the top of the application. True, the visual beauty and animation somewhat slow down the application, and, paradoxically, the system speed temporarily deteriorates precisely because of Clean Master. In addition, the program is replete with additional modules (antivirus, CM Family, etc.), which are not of interest to all users.
Overall, the Clean Master tweaker makes a strange impression. Although it contains a number useful functions, the interface is a bit heavy. And if there is a lack of resources, it is logical that we would not want to overload Android again.
Application from the developers of the popular file manager ES Explorer. If we go into the description, we have a more universal application than a simple task manager. ES Task Manager allows you to save battery power, clear device memory, unload, block or uninstall unnecessary applications.
In the main section, Optimize, there are 4 buttons that allow you to perform quick actions: unload all applications from memory, clear the cache, optimize memory and reduce battery consumption.
The second section of the manager is the “Task Manager” itself. The amount of available memory and battery status are displayed at the top, followed by a list running applications. Through the context menu, you can add the application to exceptions or add it to the list for auto-completion.
You can also note the energy saving section. Here you can configure Android behavior - enable or disable network connections, set options for screen, vibration and sound. In principle, the functions of standard system widgets are duplicated here.
Some modules, such as SD Card Analyzer and Applications, are only available after installing the ES Explorer file manager.
Advanced Task Manager is a task manager that is quite predictable in functionality, but a little more convenient than the standard one.
The main screen of Task Manager displays a list of all applications, information about the used memory and battery of the phone. In addition, the same information is duplicated in the notification panel and through the widget. Applications can be marked in the list and unloaded from memory in bulk. In addition, forced unloading from the device’s RAM is provided, and you can create exceptions - applications that will not be closed in forced mode.
A number of useful options are found in Advanced settings Task Manager. First of all, this is the automatic unloading of applications by choice: immediately after the screen turns off, when the application is launched, at a specified interval.
The disadvantages of this manager are that there is no sorting and detailed information by processor load for each application. Also, service management is implemented through the system interface, which is inconvenient.
