Speed up an Android Smartphone

To keep your Android running quickly, you'll want to remove old apps and files that you don't use anymore. Clearing the app cache can also free up a lot of space and improve performance. If your device is loaded down with pictures, transferring them to a computer can be the quickest way to safely back them up. Finally, you can perform a factory reset and restore the device to its original performance.

Steps

Uninstalling Old Apps

  1. Tap the Settings app. You can find this in your app drawer by tapping the grid at the bottom of your Home screen. You can also typically access settings from the Notification Panel.
  2. Tap Apps or Application manager.
  3. Switch to the All tab. This will display all of the apps installed on your device.
  4. Scroll through the list to find apps you don't use. Apps that you know longer use may be taking up space and running in the background, slowing your device down. You'll see the amount of space each app takes next to the entry in the list.
    • Some versions of Android allow you to sort by size by tapping the ⋮ button.
  5. Tap an app that you want to uninstall.
  6. Tap the Uninstall button. If this button is not available, the app likely came preinstalled and cannot be completely removed.
  7. Tap Disable or Turn Off if you can't uninstall. You may have to tap "Uninstall updates" first.
  8. Repeat for any other apps you want to remove. The more apps you can remove, the more space your phone will have. This will lead to better performance.[1]

Tips

  • Avoid apps that claim to speed up your phone. By keeping storage clear on your device removing apps you don't need, you'll keep your Android running as quick as it can.
  • As devices age, they may not be able to keep up with the latest apps, even if your device is in peak shape. If your Android device is older than 3-4 years and you're trying to use apps like Facebook and Snapchat, you'll likely encounter a lot of performance problems.
