Every app you install in your phone take some storage space and runs some background processes. The more storage space occupied or the more background processes running on your phone, the slower your phone’s performance.
You should regularly update your phone’s installed apps from Google Play. Try to get updates your apps when they are available in Google Play. Developers fix bugs and add features in new versions of apps. Updated apps perform better and faster.
Keep only the apps that you need and if you have got an app that isn’t really useful, you can uninstall or disable it. It will increase you phone's performance.
