Netizens made a tweet a few days ago and a small machine, which fitted with the 170+ exception occurred after the application of the machine problems. Small utility said a machine installed 170+ applications are definitely exceptions, unless that line specific or severe play lovers, people loaded dozens of application are almost the same. But it also raises the question: Android application installed on mobile phones affect speed? Ted Baker Galaxy S4 Case
There is a view that, we all have the feeling, the computer used for a long time, many things inside, speed will become slow, so we should always defragment the computer and reinstall the system, which, if the contents of the speed is slow. Which makes some sense, but not quite right.
Why? From the principle of slow computer start. Computer speed of speed main and CPU, and available memory size about, in computer jacket of program more has, directly of consequences is occupy has more big of disk space, these program occupied of disk space love you may not led to computer variable slow, but these software in installation and using in the usually will to system directory and system registered table in the writes some file and data, these data and file increasingly more, on will makes system increasingly bloated, led to system run efficiency declined. In addition, many programs require a certain amount of temporary disk space for data exchange, if it uses too much disk space, may also result in slower.
For Android phones, the principle is slightly different. As we all know, Android is a multitasking system, 2.x, Android's memory management mechanism, there is not much limit the number of background programs, along with the lack of stringent checks on quality, thus resulting in more efficiency and low memory condition, so the more software you install, use the longer, the more cards. However, after 4.0, Android application management system has been improved a lot, the user can limit the number of daemon (on the developer option you can choose), program activities are not preserved, saving memory.
On Android system, application contains "process" and "service", which "service" is a no interface, and long time run of application function, and not easily was terminated, and "process" including front desk process (is run, and screen Shang displayed of process and some system process), and visible process (not in front desk, but user still visible of process), and background process (was switch to background run of process), and empty process (some in program exit Hou still will in process in the resides a empty process). Process management strategy for Android will put these processes remain in memory, and to prioritize them, until the system needs more memory, then Android will automatically clears the process priority level, releasing the memory. Therefore these remain in the memory of the process usually will not affect the overall speed of the system, but once again, when the user activates the process can enhance the process of starting.
In General, unless is the need to open a large application, this time will trigger system adjustment process scheduling policy, it was operation consumes system resources, selective shutdown of the system memory, frequent scheduling will naturally slow down the system. Therefore, it is recommended that before opening a large application manually release memory close some process can significantly improve performance. But some small programs, fully managed by system.
So, why are there many users feel "application installed more phone stuck"? This is because many Android application now for their own purposes, after running in resident memory secretly sends and receives data in the background, especially now markets a wide variety of third parties, there are many who write malicious software package uploaded to lure users to download, thus dragging down the speed. So, to make their love and make a good run, the key is to keep good habits, good phone.
