part of practically any computer equipment includes two types of memory. A permanent (nonvolatile) memory is used for storing MP3 songs, photos, videos, documents and other important files. What's the difference with RAM? What affects RAM, how many GB need modern smartphone? All these questions will be answered in this article.
What's in memory?
Any smartphone consists of many components. Most of all the operating system performance is affected by the Central processor (CPU). Second place in this ranking of course is memory (RAM). If this component is very slow and the free space was very low, the system and most applications will experience slowdowns. As an example, let us remember the very first smartphones based on Symbian, the RAM which was calculated a few megabytes. On those devices it was almost impossible to put the music on pause to answer an incoming call — when you return to the music player track day, as RAM was not enough space to store the current position.
The main difference from the RAM permanent memory is volatility. When the power goes out — memory is reset. But this type of memory is much faster than ROM.
and then, And now RAM is divided into several conditional sections:
- System here is operating system (Android, iOS), as well as all kinds of service modules that were preinstalled by the manufacturer of the smartphone. In the same segment may be present and a proprietary shell. System section is filled with information very first. The more high-speed memory used in the device, the faster is the loading of the operating system.
- User — this memory is accessed after the ending download of the "OSes". This section contains Executive files of different applications the Internet browser, instant messengers and others. Also here gradually, you may see additions to the firmware issued by the manufacturer of the gadget in the form of updates.
- is Available is a small section that is reserved by the operating system. This "reservation" is needed to prevent problem situations and quickly launch a new application.
What affects memory?
What benefits accrue to the user if the smartphone has increased the amount of RAM? This device can operate in the background of a greater number of applications. That is, the Internet browser will not be from zero to load the page, if you returned to it after visiting many other programs. Also when a large amount of RAM in the background can run a huge number of instant messenger, torrent client and apps of other kinds. But the performance of the operating system depends not only on volume, but from the speed characteristics of memory. Affect the functionality of the Android OS or iOS, and optimize an operating system.
When bill gates said that any computer will suffice 640 KB of RAM. Now, even the mobile "OSes" takes about 1GB, but this still need to add a proprietary shell and then install the application. And if the code is poorly optimized, the brakes and hang will occur in any case. A good example is smartphones and the Samsung released until 2015. RAM in such devices have been enough, but bulky and unoptimized interface was literally gadget from time to time to slow down.
From the amount of RAM affects the battery life. Here, everything is banal. A larger number of background processes quite heavily loads the CPU. And this, in turn, entails high energy consumption. Smartphone manufacturers struggle with this due to thinner process technology chipset, larger battery and better optimization of preinstalled software.
The amount of RAM you need a smartphone?
As mentioned above, the Android operating system can take anywhere from 512 MB to 1 GB of RAM. Also RAM is needed for those applications that will be installed during use of the device. This means that now is not worth buying a smartphone, in which there is less than 2 GB of RAM. And this is the minimum setting! If you want to buy a device that just will not unload from the memory of the recently running applications, then you need to think about the device, the characteristics of which are 4 GB or even more RAM.
note, to overdo it is not worth it. 8GB the RAM is just a marketing ploy. Android yet simply cannot spend such a huge amount. Learn to do it only future versions of the operating system that for the selected device, quite possibly, never will.
How to release memory?
Many smartphone owners seem to release RAM is enough to access a list of previously launched apps, and then click "Close all". In part, this helps to free up some RAM that will contribute, for example, a better running game. But sometimes you need more effective methods.
A corporate shell have built-in means to release memory. Unloading of applications can happen automatically, once a certain period of time. But more often to free up memory you have to manually. Consider the order of user actions on the example of the smartphone from the company Samsung:
Step 1. Go to "Settings».
Step 2. Click on the item "Optimization».
Step 3. Wait for the end of the test device, and then click the "RAM". Either click on the "to Optimize" if you want to free the constant memory.
Step 4. The section "RAM" will be running additional checks. Then you need to click the "to Clean". The system will pre-tell, what amount of RAM will be released.
On smartphones and tablets of other companies integrated utility-the optimizer may be somewhere in the menu, visit "Settings," then not required. There are original shell and a built-in without the possibility of release of memory. Fortunately, nobody prevents the user to download from Google Play a special Annex dealing with the same. On clicmanager.net there is a separate article about the best SEO for Android — remains to choose the appropriate option. Let's try to download and install the CCleaner.
Step 1. USn the application established. When you first start you will need to press the button "Start».
Step 2. The program also can offer to upgrade to the paid version. It is devoid of advertising and supplemented by some useful functions. If you still spend money you do not want, then click the "Continue free».
Step 3. In the main application window, set the filled amount of ROM and RAM. To understand what amount it is possible to release, press the "Analysis».
Step 4. When you first start to fresh versions of Android there is a warning that the utility needs permissions to work with certain sections of the operating system. Click the " Clear" and grant the requested permissions.
Step 5. The analysis can last quite a long time — it all depends on how long CCleaner was run the last time. When the process is complete — you need to put ticks near items that can be removed permanent memory. After this it remains only to click the "to Clean».
Step 6. In the future you can tell the program to automatically clear RAM and ROM. This is done in a separate section. However, to activate this feature, you will need to purchase the paid version of the app.
Clearing RAM on modern versions of Android is a rare occurrence. Basically, this action may be necessary before you run some very heavy games. Overall, about RAM, can not think, if the volume of this type of memory is equal to or greater than 4 GB.
This article made it clear, what is the RAM of the smartphone. RAM is considerably faster flash memory, but it requires a constant supply of energy, without which all information is simply deleted. Suggest to familiarize with the how to increase memory — this article is also highly relevant for owners of budget smartphones.
