Tip Acceleration for Android smartphones

Over time, you will feel the speed of your Android phone becomes quite slow and can not meet demand.  following article will show you some simple ways to improve speed for your phone without having to do a lot of complicated steps.

The update of the operating system and applications more severe

Software of Android phone was much different than a year ago. Did you get the updated version of this operating system, but they may not fit your device and can slow it. Alternatively, the network or the manufacturer has included in the updated application bloatwaretrong. Bloatware will run in the background and make the machine run more slowly.

Also, whether you are using the newer application versions or updates of the applications you have used a year ago, then the application will become more severe over time. Because more and more smartphone hardware improvements, the developers have created games or other applications that can integrate a complete hardware faster and they will become worse on older devices. This seems to happen on all platforms.

Solution:

Most people choose to install custom ROMs, and indeed a lot of phones that much faster. With most Android phones, there are a few or numerous custom ROM reserved for them. The most popular custom ROM now includes CyanogenMod, MIUI, Liquid, AOKP ...

Applications running in background

You probably will increasingly install more applications for your device. Some applications open when you boot the machine and run in the background, they consume a lot of CPU resources and memory occupancy of the device. If you have installed multiple applications running in the background, we can slow down the device. Also, animated wallpapers and a large number of widgets on the home screen as well as significant impacts to your device.

To check what applications are running in the background, you visit the Apps in Settings and navigate to Running.

Solution: disable the animated wallpapers, widgets relocation and removal of unnecessary heavy applications.

A file system is almost full

The solid-state hard drive becomes slow when you fill them, the same file system can be very slow if it is almost full. Storagetrong Application Settings screen will only show you the device's memory is full, and how something is occupied storage space.

Cache memory can consume a lot of storage space, so please clean the cache to help you remove the files that were installed but no longer used. You visit the Settings section of the application that uses the cache as Google and click the button to clear your cache (Clear Cache) to clean data cache.

Solution: uninstall the apps you do not use, delete unnecessary files, and delete the cache to free up storage space. You can also perform the restore status quo for the time as new devices shipped and installed only the applications you need to get equipment working like new.

Lack of adequate support TRIM

Lack of full TRIM support are the main reasons that makes the tablet Google Nexus 7 slow first time. This problem has been fixed in Android 4.3. On the Nexus device, the Android 4.3 update will help to overcome this problem.

If you own an older devices that have Android 4.3 and has not slowed down, you can implement TRIM by rooting and using LagFix applications.

Solution: please root your device and run LagFix if you are using an older device. This happens automatically on devices running Android version 4.3 or higher.

Why Android smartphones as users increasingly slow?

You feel your phone and your Android tablet running increasingly slow? Here are the reasons of this situation and how to fix it.

Due to the operating system and application upgrades worsening

Your Android phone is no longer used as the software has launched, which is also the reason why the machine run more slowly.

Specifically, when you get the update Android operating system, and this update is not perfect customization for your device, it can cause the machine to slow down. Or, manufacturers, network operators have additional applications in your computer, the application runs in the background (background) and delayed making machine.

Even if you have not updated, the application running in your device as well as a cause.

Whether you use the newer application or the updated version, the app seems to be getting worse.Because when developers reach faster smartphone hardware, games and applications can be customized for this faster hardware, and so they're less active than on the old device. This usually happens on all platforms.

And over time, these sites have become more severe, the application needs more RAM, the game needs more hardware.

 Solution: For this problem, there are many solutions for you. If the operating system is running slow, you may want to install a custom ROM like CyanogenMod, CyanogenMod for no bloatware software - that is, the application is added to the device by the manufacturer put on the same operating system . If your application is running slowly, look for other alternative uses lighter.

The application platform

There are more and more you can install more applications. Some applications that start up when you open the machine up and running in the background, consuming CPU resources and memory hungry devices. If you have installed multiple applications in the background, they can make your device slow down. The Android operating system provides multitasking, so apps can run in the background.

Applications running in the background can also consume a lot of resources. To check what applications are running in the background, go to the Apps screen in the settings app, and move them to another mode. If there are any applications running in the background that you do not use, uninstall them. If you can not uninstall because it was the default in the device, disable it. You do not end application, as it will automatically restart.

Solution: Please disable the wallpaper, removed the widget and remove or disable the applications that you do not take seriously. In fact, you can remove, disable all applications that you never use.

Coming full file system

SSD hard drives will slow down when they are full, so writing to the file system can be very slow.This makes the Android operating system and applications also operate much more slowly. Storage screen in the Settings app will show you the remaining capacity of your equipment, and what occupies this space.

The cache file can consume a lot of storage space if allowed to develop freely, not under their control, so deleting all the cache files can free storage space and help the file system you perform better. To delete stored data at the same time for all applications, open the Settings app, in the Storage section, scroll down and go to the Cached data, and click OK.

Solution: again, clean up the hard drive of the machine will run faster. Uninstall apps you do not use, delete files you do not need to catch and clean up files to free up memory.

SSDs do not support TRIM

TRIM is a technology that allows to improve the speed of the action recorded current data on the SSD only. The SSD TRIM support allows to improve write speeds than conventional SSDs and especially when compared to mechanical hard drives. The lack of TRIM support is the main reason Google's Nexus 7 tablet slowly over time. This error has been handled in Android 4.3, adds support TRIM. On the Nexus device, the Android 4.3 update to solve this problem.

If you use the older devices running Android 4.3 and not the machine slowly and gradually over time, you can perform TRIM by rooting and LagFix application. This application is similar fstrim run Android 4.3 in the background. TRIM is essential for SSDs - because SSDs slow down over time due to the flash memory slot must be removed before they can be recorded. TRIM will remove the slot containing the data from the deleted file, make sure everything will run as fast as possible when Android needs to burn up the slots in the future.

Solution: Root and run LagFix machine if you are using older equipment. Android devices running Android 4.3 and newer versions have TRIM support, so you can be assured of this.

Android 4.4: important turning point run smoother and increase smartphone battery life

Throughout history, rapid growth and prolong choppy 5 years, compared with operating system version first, almost every aspect or feature of Android 4.4 has been changed. Every time Google releases a new version of Android, which are updated or upgraded fairly comprehensive, but everything except the most important: Dalvik. Accordingly, the virtual machine is responsible for running most Android apps remain like this since the first day. And to this point, Dalvik has revealed signs of age, slowness is visible. To keep pace and meet the demand for higher levels of users, Google has decided to use ART (short for Android Runtime) on the Android operating system version 4.4 to replace Dalvik KitKat. ART first version integrates with Android 4.4 can accelerate applications by 100%, while the complete version will be even better.



When you run the software on electronic devices, such as PC or smartphone, almost always your machine to run the compiler "compiled code". The compiler is responsible for shifting the source code written in a high level language into object code or machine language which can be executed directly by a computer or by a virtual machine. For example, if you open an EXE file, you will see the compiler "gobbledegook" help CPU can perform load cycle to start the application. Windows, web browser, Crysis 3, Linux, iOS apps are all examples that use the compiler.

Next, we are a different kind of code interpreter called "interpreted code" with many different types, but have one thing in common is that they can not be done directly by the CPU load. First, the interpreter must be decoded into machine code by a process called translation system JIT (Just-in-time). For example, the most popular of the JavaScript interpreter, according to which, the web browser will compile / interpreter code when a user visits a web page using JavaScript.

In addition, a typical example of the Java and Dalvik interpreter is essentially a "Google version" of Java. With Java, developers can write applications once only, and then convert it into the language of the hardware platform through an "interpreter" named Java Virtual Machine.Explains a lot, but we can generally shortened to the point that Google has decided to use the Dalvik virtual machine for Android app. This way, a developer can write a single application Dalvik and be assured that it will run on smartphones, tablets, TVs or other devices.


The chart shows the performance of JavaScript (red / green) than when compiling the source code (orange).

But now, the shortcomings of the interpreter "interpreted code" is it really slow. For example, JavaScript can be up to 20 times slower than the same code compiled with C or C + +. Java / Dalvik is not too slow, but can not compare with the speed of the original compiler. In many cases, especially with the processor's advanced 4, the speed difference is very clear. We can not be blamed entirely for the cause Dalvik Android devices lag or battery power, but this is certainly an important factor causing this. Basically, the Dalvik interpreter takes longer to decode and to calculate more CPU, so it directly reduces the battery life and smoother overall mobile device.

Android Runtime - ART

While using session Dalvik JIT (Just-in-time) to decode, ART on Android 4.4 using process AOT (Ahead-Of-Time). First visible effect of shortening the time it is decoded meaning shorten boot time, help applications launch time 2 times faster than the old Dalvik process. By activating ART, each Android application will be compiled into native code when you install it. Then, when you launch the application, it will act as a root application installed on your computer.



Currently, ART is still in the experimental stage, but you can still activate it on the machine running KitKat Nexus by going to Settings> Developer options> Select runtime, then just wait for the machine to reboot. This change also accounts for part of the machine capacity (increased about 10% to 20%) because your code is still being finalized. Maybe you will not notice the change of AOT for small applications, but for larger applications, the delay will be remedied. In addition, the main advantages of ART is to allow Android developers continue to write code and run on multiple handsets with different hardware configurations.



ART has been tested and Vietnam expressed its advantages: increased battery life, smoother handling and speed up application open. Once ART is fully developed, the current Android OS can be "disappeared", but instead is a new operating system faster, more powerful and more Vietnamese priority. Benefits are more easily seen when you run compute-intensive applications such as photo editing or video editing. At the same time we can hope for a smooth run Android as what iOS or Windows Phone has done.
