How much running memory is your mobile phone? Generally speaking, in order to give consumers a variety of choices, the same model of mobile phone will have a variety of configuration combinations, such as running memory will generally have 4GB and 6GB versions or 6GB and 8GB versions. It is generally believed that 8GB memory is not necessary at all. Most people will wonder how to choose 4GB and 6GB memory. Today, Xiaobian will talk about whether to buy 4GB or 6GB memory for mobile phones. In fact, many people have chosen the wrong one!
What is running memory for
To understand this problem, we should know what the running memory is. Flash memory is equivalent to the hard disk on the computer, that is, the "warehouse" of the mobile phone, which contains a large number of system files and personal data. Your photos, music and videos are all stored here. The running memory is equivalent to the 'container' of the system and app. When you click the app, the processor will call the app's resources in flash memory, read them into the running memory, and then run them in the running memory. So from this point of view, the larger the running memory is, the more apps are running at the same time.
Composition of running memory occupation
The running memory can be divided into three parts. First, the Android system resources. For example, if the 4GB memory of the new mobile phone is only 2.5Gb, then the 1.5GB is basically occupied by the Android system. The second part is the occupation of third-party apps, such as foreground programs, background processes and so on. The third part is the remaining available memory, which will be used preferentially when a new app is opened.
Should I clear the background
Many people have totally different opinions on whether Android phones should clear the background. Some people say that is too laggy. They will not be empty, but the space will be stuck. Do you need to clear the backstage? I don't think it's necessary to clear the backstage for fluency at this time.
First of all, Android system is not a fool, it has a complete set of memory recycling strategy and management mechanism, and it even intelligently mobilizes the memory occupation of applications. For example, at present, the five programs of ABCDE occupy 70% of the memory. At this time, 40% of the memory is needed to run the F program. The system will intelligently judge and select some programs to close or compress so as to leave more space for the F program. The system will automatically complete this process without your concern.
So to some extent, a higher memory usage is often a good thing, because the app can load and open faster when you open it next time when you live in the background, which is why MIUI 10 does AI preloading.
How to choose
From the above analysis, it can be seen that the biggest gap between 4GB memory and 6GB memory experience is how many apps can be run at the same time. After one year's use, two 4GB memory phones in my hand can run about four large and medium-sized apps at the same time. Any more will be killed in the background, but there will be no stuck problem.
In addition, it may be a little faster than 4GB when loading programs under high load (because other programs will be killed first when there are loading programs in 4GB), but 6GB daily use will not be much smoother than 4GB. So in terms of fluency, 4GB is the best choice for the bottom line, 6GB is enough, 8GB is luxury.
