Android comes with all the awesomeness, this is an open source project, so that everyone can contribute to its development to make it faster and more reliable. As an ordinary user, you can also make Android run faster. There are many things you can do, if your Android has been rooted, then you can do more advanced things.
I have made a list for you, and some of them require root access. Check them out!
1. Turn off animations
Enable the developer option by tapping 7 times the build number in About phone section
If the developer options has been enabled, go through it and disable all animations in Window animation scale, Transition animation scale, and Animator duration scale options.
2. Use a static image for wallpaper
Please, don’t use any live wallpaper if you want to make your Android run faster.
3. Reduce the amount of widgets on home screens
Widgets are very functional, but please don’t use them to decorate the home screens. Use the important widgets.
4. Reduce the amount of home screens
Home screens are also functional, but make it more efficient with two or three screens.
5. Check recent apps and close the unused apps
After you close an app by pressing back button, actually it’s not completely closed. Check it on the recent apps, you can open it again with the last time view is closed. It means, the app is not start from the beginning.
Swipe to left or right to close an app.
6. Change the launcher, use a lightweight launcher
Typically, the stock launcher is quite heavy, even more if the launcher uses a lot of animations. Change it with a lightweight launcher, there are a lot of choices in the Play Store. FYI, Nove Launcher is a higly customizable and I’ve been using it for long time and I have never had any problem.
7. One purpose, one app
There are many news reader apps, but come on, choose the best of them. Use one app for one purpose.
8. Clear cache and junk files to free up the phone storage
It could be that you save gigabytes of junk files in your phone storage, you can remove them using a cleaner app such as Clean Master.
9. If you are using KitKat, switch to ART
Many people said that ART is faster than Dalvik and it is also more efficient for battery.
Go to Developer options and switch the runtime.
10. Uninstall unused apps
I think it’s very clear. Try App Eater to uninstall apps in bulk.
11. Reduce the amount of syncronized data
In the Account settings, you can choose the items to be syncronized, so choose wisely. If you are not going to use Google Contacts from an account, then disable it.
12. Factory reset
All the phone settings will be restored to the default, it’s like a new phone settings. Don’t forget to backup all your important data.
