7 Best Ways To Speed Up And Improve The Performance Of Any Android Smartphone

As A Nigerian It’s frustrating to spend several thousands of money on a high-end smartphone only to find that the smooth and speedy performance you expected remains elusive. Mid-rangers and the budget end of the market are even more prone to stuttering and lag. There are various ways to speed up that Android performance, and a few things you can do to make it feel faster.
...

1. TURN OFF/REDUCE ANIMATIONS
Imagine; You tap the home button but you get home before your phone does... Ahh! 
You can make your Android device feel snappier by reducing or turning off some of animations. You’ll need to enable Developer options in order to do this. Go to Settings > About phone and scroll down to the System section to look for Build number. Tap on it seven times and you should see a message about being a developer. You can now go back to the previous menu and you should see Developer options listed under System. Head in there and scroll down to find Window animation scale, Transition animation scale, and Animator duration scale. Tap each in turn and set it to .5x or off. Pick an option and find out what suits you, if you don’t like just go back in and change the values again.
I personally have window animation turned off on my device.

2.TURN OFF AUTO-SYNC
This causes a major lags on a some Chinese phones I've had access to..
Most of us end up adding a list of different accounts to our Android devices and we allow them to automatically sync in the background to pull in new data and provide us with updates. All this syncing has a big impact on performance, not to mention battery life.

You could go to Settings and find Auto-sync under Accounts and just turn it off altogether, but that will be too drastic for most people. Instead why not just reduce the sync frequency and remove any accounts you don’t really need? For a lot of apps, like Facebook, you’ll need to open up the app and find the settings to reduce the sync frequency.


3.UNINSTALL AND DISABLE BLOATWARES/APPS
BLOATWARES,, malwares? they eat up ram With time 

Bet, You certainly don’t want to allow apps that you never use to take up space on your device and potentially eat into system resources. Go to Settings > Apps and swipe over to the All tab. Take a good long look down the list and identify the apps you don’t want or need. If you’re in doubt about what any of them do then it’s time to hit Google and check.

Now, tap on any app you don’t want and then choose Uninstall or, if the option is not there to uninstall, tap Disable. Disabled apps will be listed in a new tab, so you can always enable them again in future if you change your mind.
You should also take a look in Settings > Apps at the Running tab. Some apps want to be running all the time and they can seriously impact on performance. Think carefully about whether you need what’s listed there.
I personally don't keep apps I don't make use of especially, Facebook and Messenger jeez! Zuckerberg's Space mongers...
I prefer Facebook lite or messenger lite.. I think you have to.

4.CLEAR CACHED APP DATA
Cached data for apps should help them to load more quickly, but it can build up over time to take up quite a lot of space and there will potentially be cached data in there for apps that you no longer use. Sometimes clearing cached data for an app can also help clear up flaky behavior, Yes, especially on browsers.
If you want to pick individual apps then head into Settings > Apps and slide over the All tab and tap on the relevant app then choose Clear cache. If you’ve decided to just clear the whole lot then go to Settings > Storage and tap on Cached data and then tap OK.


5.CLEAN UP YOUR HOME SCREEN [little or no widgets]
If you choose to use live wallpaper then consider replacing it with a good static image. You should also clean away any unused icons and limit your widgets to the essentials. The less cluttered your home screen is, the better in terms of performance.

Also do good to make use of static black background image like me..



6.UPDATE! UPDATE!! UPDATE!!!
The latest software will often contain bug fixes and general improvements and it can help your Android device to run better. Software updates tend to come OTA (Over The Air) and you should be automatically prompted to install them, but it doesn’t hurt to check. Go to Settings > About device > Software update and check for updates.

But, update files can be so large..with little bug fixes.
The same logic applies to apps, so fire up the Play Store, open the menu at the top left and tap My Apps and make sure all of the apps you use are up to date..


7.FINALLY TRY A FACTORY RESET
This is a drastic step,, I recommend that you do a factory reset periodically if you want your device running in tip-top condition. It’s a shortcut to cleaning up your device and getting rid of any junk you’ve accumulated, but it means wiping all of the data and settings. If you decide to try it then make sure you back up everything that’s important to you first. You can find the option to do it in Settings > Backup & reset > Factory data reset.

BONUS TIP: 
Your device can be laggy because of too much processes running in background, even after attempting the above solutions.

You’ll need to enable Developer options in order to do this. Go to Settings > About phone and scroll down to the System section to look for Build number. Tap on it seven times and you should see a message about being a developer. You can now go back to the previous menu and you should see Developer options listed under System. Head in there and scroll down to find Background Process Limit, Click and select > At most 2 processes or At most 3 processes.

But, After a reboot it goes back to default,,, 
do the same process all over and enjoy flawless multitasking.
Please comment other suggestions.
Thanks.
