How to fix : Boost Android's speed performance

Speed is essential for your smartphones, after a while your phone's speed might reduce, it could be caused by high RAM usage, large amount of unused files/apps and many things(the ones that we will review) that posibbly could have interfered with speed performance and battery life.

You can see RAM used by your Apps
And you could try these solutions to speed up your Android phone's performance.

Boost Android phone's speed

• Use Back key to close current running App rather than using the Home key, Home key allows the App to run in the background, running Apps in the background still using some of memory, and also decrease battery live.
• Avoid so many home screen more fancy the home screen more memory used. 1-3 home screens is proportional for low or middle end gadgets.
• Don't use live wallpaper everthing related with Display consume a lot of battery life and memory usage, static wallpaper (or background) save memory usage and battery live.
• Avoid using so many widgets(installed and/or running) especially widgets that need Internet connection to do their tasks.
• Uninstall unwanted/rarely used Apps, you can go to Settings » Manage Applications, from this point you can also clear the cache for each of your Apps. If you use a launcher App, it might have a reminder about rarely used Apps
• Do Apps Syncing manually you can find the settings in Settings » Accounts and Sync » Auto-sync, please notice disabling auto-sync will make apps that need background data to automatic sync won't give you any notification/update contents until you sync them manually. Auto-sync is one of the things that makes your phone "smart", gives you recent news/updates/e-mails etc, so just don't forget to sync apps manually after you disable this feature.
• Delete old text messages, save a bit bytes from your memory press and hold the message » tap delete form the context menu
• Buy High-speed external memory card.
• Uninstall glitchy apps, if an app have a problem and sends you so many times of "Force close", I think it's time to update the app or uninstall it, this app will slow everything down because the hardware and Android OS will work harder to run this kind of App.
• Don't root if you don't know for sure about rooting, people probably will say "root" to boost more speed, it's true but if you don't know the risks or you know what root is from some tech magazine you've read once 3 years ago, just don't!
• And remove those shortcuts from your home screens.

Note : I don't think RAM booster Apps really work well enough, it's just contradictive because Apps need RAM to work but to boost phone's performance (one of the things) you need to free more memory usage. If you want to prevent some Apps running automatically in the background to save some memory you can update your phone OS, if you use old OS update to Android Ice Cream Sandwich that has built-in setting to do this.
